im quite new here so here goes....
im using a pioneer component with built in dvd player but no dolby digital nor dts capability. More specifically, its the vs 300 model i think...
anyway, im just pissed cuz i cant enjoy my dvds even more due to lack of the above mentioned capabilites..
well, i tried checking out the manuals and it stated that it has a digital output...whatever that means ;D well, i guees i cn attach a decoder ,am i right?
1. well, my question is that where can i buy one of these decoders? I hope i dont have to buy a receiver cuz they really are exepensive but i do wna enjoy Dolby digital or dts output sana ;D
2. is there such a thing? just a decoder and not a receiver?
3. how much would it cost?
thnx ya all and hope you can help me out! 8)
Gaol/Bently,
I'm afraid egzbuen is correct. Pioneer DID come out with DVD mini-components without DD or DTS decoders.
In November 2000, I helped a friend canvas for a mini-compo with DVD player. That's how I became aware of this.
Sayang, I no longer have the Pioneer brochure with me but if I'm not mistaken, the Pioneer DVD mini-compos only had decoders starting with the VS500DVD. Since egzbuen says he has the 300 model, I'm afraid that does not have any decoders.
EGZBUEN,
Yes, your component may have a digital output, but I believe it doesn't have a 6-channel input. So even if you get a separate decoder, you'll only be able to connect the component to the decoder. but from there, wala na :(

Thnx guy for replyn asap! =) anyway, ill check my manuals again to make sure,ayt? Btw, wat do i look for? I just have to check that it has DTS stream and/or DTS surround out?
Thnx for the warm welcome guys!
GAOL : yup ppc also,wats your handle there? =)
buys ...this is the link of my unit
http://www.pioneer.com.sg/products/av_index.html
and the model is VS300DVD under mini systems....
thnx ya all! =)
you can still use the speakers on this unit pero kailangan mong ilipat yung speaker wires doon sa bagong receiver.
bently
good point jt, pero nakita ko kasi doon sa spec page ng pioneer na rated at 140W X 2 RMS yung output noong amp.
so if he got a new receiver/amp with an ouput of 100w per channel, then he should be okay..or he can just use this speakers as his rear...just to be safe ;)

yikes! so im stuck with this setup right now...
cguro it wud be better if i sell this...
considering i bought this for 26T and still has 2 years full warranty, how much can i sell these for?
anyone here tried using the VS500 series, tehy have built in dts and dd decoders na....
now, how am i suppose to sell these without getting to luge.... ???

mag sirs curious lang po...:)
if in fact the unit (pioneer mini compo/dvd) is used only as DVD player with dd/dts output sent to an external decoder/avr (whatever), nde na po ba tutunog ang speakers nya? o there is a need to for the speaker wires to be detached physically?
i was thinking along the line parang sa headphones, pag sinaksak sa jack, nag shut off ang speakers... ???
salamat po sa anumang paglilinaw na maipapaabot ninyo mga ka forum...
Are there any "amplifier-less" AC3/DTS decoders that can be bough here in Pinas?

mga katanungan po :D....wat is a solid state amp?....how does it differ from an intregrated amp?...does it has voluome level? tone?(bass/treble).....
....do all solid state amp have powerful output?
thanks!!!! ;)
1.) Does warming up producing a better sound have some basis in engineering theory? How about burning in?1. for the first 4 seconds yes, because it takes a finite amount of time for the electrolytic caps to fully charge!!!after that, its working time, solid state amps doesn't need to warm up really, as they can operate instantaneously unlike tube where the filaments takes about 11 secs to fully warm-up. burning-in is done at the factory to age the components and uncover weak parts (infantile mortality)....
2.) How much power would an amp rated at 1.5A at 230V consume if left on with the volume dial set to zero?
Yung integrated amp, preamp+amplifier. If your integrated amp is composed of transistors, then solid-state sya.
Tone controls is usually an indication ng pre-amp section.
AFAIK, solid-state amps has a wide range of output, it can go as low as 700mW (RMS) to 1000W (RMS) or more.

2. a solid state power amp rated at 1.5amp at 230volt will consume very little with zero volume, as little as 5 watts, compared to a dynaco st70 which can consume 100watts at idle....
hi edboy!
solid state amps - use transistors
tube amps - use vacuum tubes (triode, pentode, etc.)
hyrbid amps - use both transistors (normally for power amp section) and tubes (for pre-amp section)
hope this helps...thanks!
which of the three gives the best superb sound? pls enlighten me, tnx ;D
I have the following questions about speaker wire tweaks and if they can damage my ss amp.
1.)Would it be ok to use different lengths of speaker wire in bi-wiring speakers? I am currently using 1 3-meter run each of generic 12ga but have some very good quality 14 ga leftover from a previous experiment but each run is only 2.5m long.
2.) Tweakers sites recommend experimenting with the speaker wire connections, i.e., switching wires in both single run and b-wire setups to see if any improvement in sound results. Is there any possibility of long -term damage with these experiments?

"But for many audiophiles, it's the gear that gives them the most pleasurable listening experience that matters, whether it's hi-fi or not, valave or ss. So it's your ears that will decide. Personally, I prefer hi-fi ss sounds."
well said, av-phile, this is how it should be.....
You're saying that different lengths for bi-wirng are OK? Just to be sure. I'm more wary of O'brien's law: Murphy was an optimist.
Just for your peace of mind, I would suggest you make them of equal lengths. The mathematical differences in resistances are quite minute unless we're talking of lengths in the 20+meters.
mga sir, what does a higher (or lower) damping factor do to the sound? i tried reading a very lengthy technical explanation, but my short attention span left me at halfway the 20th paragraph.
is this the same as the "softness" switch in some amps?
i have an amp that sounds aggresive on some music material. when i turn on the "softness" switch, decay seem shorter but tonal balance remains the same, resulting in a smoother sound. is this an effect of damping factor? i remember seeing an accuphase amp with low/med/high adjustments on damping factor.

Will a ss integrated amp benefit from a tube preamp? say my Rotel RA-931 Mk II? Just curious since there are a few hybrid amps going around.
I tend to agree with the article in that DF is more a byproduct of negative feedback.

Class A naman.. sir, i see a lot of amps with emblems on the faceplate claiming Class A or even Class AA (Technics does this alot). I also saw in the norh site that their Le Amp II is class A in the gain stage and then class AB on the bipolar stage. What is the gain stage & bipolar stage? Also, how does a pure class A amp differ in sound from a semi-class A amp? Thanks!
Preamp question: why need for Lo Z and Hi Z -- for SS and tube amps? What's the big deal in Z's if i 'misused' them, say my preamp doesn't have that selection?
Capacitor questions:
How do bypass and filter caps differ by function? How do they affect the sound?
In replacing caps, what are the rules to follow in uF and voltage selection? How do the numbers affect the sound?
i got this old technics 2 channel amp. and it says it is class A (even have the schematic). it is rated at 60w/channel and the power consumtion is at 500watts. is this really class A?
Are solid state amps affected by vibration?
When playing music at not-so-loud volume level it's normal to feel vibrations on furniture. I can tell that it might affect the CD player, because some people put slabs of concrete on top of theirs just to dampen the vibrations. But does it affect amps? My sony amp makes a big deal out of it. The base of the chassis has a honeycomb design and the electrolytic condensers are held tight by rubber that is pressed downwards by fiberglass. Why would a manufacturer spend for that?
Vibration appears to be the primary design consideration for their fusion of silk fiber and manila hemp in their top-of-the-line SILMIC range.they can put whatever they want in the caps, but in the final analysis, it will be the quality of aluminum oxide dielectric, and the acqeous liquids that they use that will determine the outcome, after all an aluminum electrolytic is just that, made up of aluminum oxide, the other stuff they will put in will just serve as separators, so i am not very much impressed by their gimiks.....
OT: sir joan2, we may have a supplier who knows about the T-J115/K405 mosfets. he was asking are they P-ch or N-ch?2sk405/2sj115:
imho, you can cascade as many analog preamps as you like. the problem is, each stage degrades the sound. so, the more stages you have ...Very interesting. So kahit receivers pala pwedeng lagyan ng preamp.
Very interesting. So kahit receivers pala pwedeng lagyan ng preamp.
just a clarification... so this scenario possible: Power Amp + Pre AMp 1 + Preamp 2?
Another followup question: does that mean amps with pre-ins RCAs sound superior compared standard Aux RCA inputs if paired with Preamps? Am asking kasi some some integrated amps have provision for preamps and direct/integrated. Thanks!
can i use an external preamp in a processor loop?
i know i can use an equalizer here, but im not sure if a preamp would apply. the processor loop in some amps seem no different from a tape loop. is that right?

What specs (design, parts, data) to look at when evaluating a Power Amp? (Am currently in the hunt for HT setup but I consider going via the Power Amp route.)
The xFETS daze me and so are the publsihed numbers/data (which may not be true/reaslistic anyway).
First the size & weight should be hefty. If you carry it and half the weight is on one side, it means it has a big trafo, which implies high power handling, which implies a good power amp section. Of course there are exceptions. NAD C20bee and luxman hybrids are relatively light but they sound very good.
If you look at the RCA jacks at the back, and some or all terminals are gold-plated, then there may be some hint of good sound quality. I make this assumption because the manufacturer spent money on something that won't be seen by majority of potential buyers (because its at the back). Its also possible that the designer took into account the small percentage of buyers who will inspect the rear portion of the amp. Then that means they were targeting discerning buyers, not your average joe.
If its a pre-owned or surplus amp, i also check the net for the prevailing market price. If it has a high selling price, then there must be high demand, which means it must be good. In yahoo auctions or ebay you will even see pictures & specs.
If its possible to have it opened, i look at the parts used. This is where i would need an expert's help. I have an assumption that the more & bigger the power caps, then the higher the power handling? Is this correct?

Is it possible to convert the AUX input of my integrated amp into a power amp direct input?
I was hoping to use my old integrated amp as a separate power amp for my receiver but unfortunately it did not have main ins. This way i could use both the digital & analog outputs of my DVD player for playing movies & music respectively. When watching movies i switch to AUX to bypass the integrated preamp and use my receiver as the external preamp. When playing music i just switch to CD input to use the integrated preamp. I dont have to power up my receiver when playing music. I also dont have to switch speaker cables.
Akyat, I asked Mr. Rivo about that and a pre amp output as well for my Rotel. He says it can be done as long as you have schematics for your amp. Now that's the problem. Hehehe.
I remember buying some schematics from Raon. Can't remember the shop name though. I believe you can just ask some electronics shop about it.
yes it is possible. or you can put in a 1/4 in phone jack that automatically by-passes the preamp out and make your power amp direct in possible, this way you don't disrupt the operation of your integs, besides it is more tedious to connect rca plug than a single phone plug imho..
They have manufacturer model specific schematics?
hmm... i'll go back to raon one of these days to look for schematics. i saw some schematics for sale on the web but i think i'd rather get it from raon. sir av_phile, any idea how much they cost? para lang wag tayo mataga sa presyo.
av_phile,
are you into electronics too? i like your style of writing, very clear and to the point!!!
akyat,
what happens is that one stereo phone plug with rca dual jacks, will be used, now if you want to use the power amp only, all you do is plug it in, then when you are done just unplug it, and your system goes back to normal...i can even rig you switching breakout box so that all you do is just turn the knobs to whatever your setup requires...
i think i'll prefer the socket to be at the back. my short interconnect may not be able to reach the front. ideally though, it would be nice to have some kind of switch at the front bcoz the back of the amp would be hard to reach in my case. i wonder if its possible to hijack one of the unused switches like the "softness" or "subsonic filter"? i can see that the AUX input idea may not be possible.
Toroids + EI transfos: can these be interchanged in an amp, provided their specs are identical? Are there other considerations (except space perhaps)?
Am considering replacing some toroids but so far can't find local winders of such.
well, this can wait. am actually contemplating converting 220 to 110v and reading from previous posts, may try higher rating (VA?) for more power.
btw, why do other amps have autovoltage features? is that a design of the transfo or is there another device in between the transfo and the mains cord?
thank you Joan...
well, there's no shortcut to auto-volt. A swtiched/multi-tap will be economical indeed.
followup question: is there a way to protect a 110v component by adding a fuse (or something) that will break in case it's plugged accidentally to 220V?
About the speaker A & B terminals of an amp: Aren't they just connected in parallel?
I was wondering if this can be used to compare speaker cables. I'll plug cable A into speaker A, and cable B into speaker B. Then both will connect to one speaker pair with the HF/LF jumper in place. So when i switch to speaker A, i will be listening to cable A... when i switch to speaker B, i will be listening to cable B.
Now if i switched on both A & B with the jumper in the speakers still in place, will it short my amp? Note that the + and - aren't touching, just A+ to B+, and A- to B-. Well actually i know the answer to this one coz curiosity got the better of me and i couldnt resist. Not the most scientific procedure that, risking a short like i did, but in case people out there are starting to get those bright ideas, at least the gurus here could warn them.
yes, i posted that in akyat's thread about surplus amps, when akyat comes to my place, we will take pictures and post the schematics, a cheap tweak that can save you a lot in repair costs...
which of the three gives the best superb sound? pls enlighten me, tnx ;D
are power transistors just like power tubes -- when you change them, you change the sound of the amp?
or is it that the sound of an amp is made up of all its parts, so changing a power capacitor or the transformer will also change its sound? if so, which parts will have the most effect on the sound when changed?
There are 2 school of thought in comparison:
- the objective point of view
- the subjective point of view
The Objective point of way is to make parametric measurement of the performance of each amplifiers. The best of breeds of both type of amplifiers (tube and SS) yielded that SS always won hands down.
In some actual listening where both types have been tweaked to be of same loudness, the differences were hardly determined, especially if both amplifiers worked with less than few percent distortions.
The subjective point of view is where the word "superb" may rightly fall. "superb to whom"? Thus, the preferences of a person to the sound balance he likes determines superb condition. And there is no standard here, and also there is no point arguing which is superb and which is not. Part of the consideration here is the fact that our hearing deteriorates as we age. So different age groups may have different tonal inclinations.
With digital age, such subjectivity is more of a goner because the distortion or alteration to the sound can now be done in digital domain - very clean - and with various equalization in digital domain, sound of whatever you want can be tailor fitted to any amplifier. Its interesting to note that generic DVDs have built-in equalizer tool being applied in digital domain - and will be decoded by any AVR equipped with DACs.
Some people still go with tubes because it has vintage values (aesthetics), some still wanted soft clipping, and some wanted its tonal balance (distortions). To them, these are "superb"-ness. To others, these things may not be the case.
going back to ss amps, not all ss amps that measure well in terms of thd and im's guarantees it will get good reviews on actual listening tests!!

Are you saying that the tube users are enjoying distortions? So if you distort a SS it will sound like tubes?
Rather than ignore them, maybe it'sa good idea to educate consumers about them, so they don't get duped by savy marketers of lousy products. Then again, maybe not knowing about these number is just fine so savy marketers can't use those numbers to dupe consumers. In my case, I am just too old in the hobby not to know.
Are you saying that the tube users are enjoying distortions? So if you distort a SS it will sound like tubes?
In my own view, any form of harmonics that are not there with the source signals re-shapes that signal and is not my piece of cake. Whether they sound pleasant or not, i just can't enjoy the music knowing at the back of my head that something is being added to the sonics that is not supposed to be there.
same reasoning with jofverski. Same school?

he's passionate, you are full of compassion!!!
is it possible to get the best of both worlds? - a high power, low cost solid state amp that degrades gracefully like tubes. i don't really understand Gabe Velez's explanation behind his circuitry, but i do understand the claim he is making. well, the title says it all: the solid state tube. i'm just curious if anybody has verified it yet or whether it has any merit technically.
hi sirs, did i get it correctly, that the main difference between tubes & ss are in the way they handle clipping? tubes just have more finesse when pushed to its limit. if so, then the trick is to make the ss amp so high-powered that it will never clip? but the argument from the tube camp is that all amps will clip anyway because the musical peaks will require 1000w or more to reproduce without distortion.There are more differences such as slew rates, rise times, THDs, noise floor, frequency response, microphonics, etc.

ss class A amps can give tubes a good run!!! with ss amps, the rule is not to play it real hard so it does not clip, most of the listening will be done in the 250mW to 2watt or so range anyway, so an amp rated for 250watt continous ave, will have plenty of headroom!!! a good ss state amp in my book will have the following specs:
4. all stages operates class A except the output transistors
5. uses cascoding in the vas stage.
6. is push-pull from input to out put
If you want to make a solid state amp sound like vacuum tube...then just use tubes.
Can you have push-pull all the way? Don't you have a basic single ended input, then a splitter, then driver then the output...which is only the push-pull? Or the PASS amps that are single ended all the way.
Good SS amps, have the output stage in partial Class A...that is why the A/B class. You want all in class a except the output....?????? That will be a bad amp because of the transistor switching on and off....noise...at very low wattage...that would be very audible....or do want a digital amp.
What do you think of transformers? Colored?
Anyway what Solid State amps are you talking about? Does it include the common receivers like Pioneer,Marantz, Denon, Onkyo, Yamaha or Harman Kardon? My receiver is a solid state and very good sounding but its a far cry compared to my ordinary vintage tube? I dont think that Im just appreciating distortions because I have been using solid state ever since and I know what is good and bad. I did not try tubes if I was not impress with the sound. Im not referring to the high end solid state but Im just comparing a vintage amp to an average receiver. Aside from all the technical explanation which doesnt prove anything that it would translate to a good sound, why is it different? Listening and enjoying is different than reading and be fascinated by the specs. Guys any experience owning and listening to a tube amp for a long time?
i hope this thread doesn't turn into a tube vs. ss debate. this is for the benefit of those willing to learn about ss.

But what you are suggesting is in fact being done - allow more power bandwidth so that the onset of clipping beccomes unnecessary at listening levels. Many audiophiles actually shy away from modestly powered SS amps which is basically the province of entry level stuff and go for those that give at least 250 watts RMS per channel with instantaneous current handling capability reaching as far as twice that. Clipping is almost never reached at half volume or more for either continuous and peak signals. So get the most powerful SS amps you can buy and enjoy!!!
ss class A amps can give tubes a good run!!! with ss amps, the rule is not to play it real hard so it does not clip, most of the listening will be done in the 250mW to 2watt or so range anyway, so an amp rated for 250watt continous ave, will have plenty of headroom!!! a good ss state amp in my book will have the following specs:
1. an open loop bandwith of 20hz to 20khz.
2. a gain bandwith product of at least 8mhz.
3. has every stage with local degenaration.
4. all stages operates class A except the output transistors
5. uses cascoding in the vas stage.
6. is push-pull from input to out put
7. a thd of less than 0.2%

the path that you took, imho, is the best way to do it, you will appreciate tubes more if you started out with ss then migrate to tubes, i started out in the opposite direction, i built my first tube in 1968 from parts borrowed from a friend, i am not a convertional type, going along known paths...i started with ss sometime in the early 70's. i still remember the saturday's we spend at the national library looking at electronics magazines and trying to absorb as much as we can..i built my first ss amp around middle of 70's and my first leach amp in 1982....unlike some people, i do not keep a closed mind with regards to which is superior, tubes or ss, there is more to amps than just the superiority game!!!! i try to study amps circuitry tubes or ss and maybe second guess what the designer had in mind when he decided to build such an amp, his choice of components, etc...this gives me a lot of satisfaction....
in japan, they have what we may call "fads", in the begining, there are germanuim transistors with totem pole outputs, then came the silicon npn's in a quasi-complementary output, single ended input, boot-strapping drivers, were common...then came the long-tail-input(differential amp input) which still is common up to today, also about this time pnp output transistors came about, thus amps which are push-pull from input to output became a reality...
then there is Mr Nelson Pass, an icon in the amps buissines, his Threshold Stasis amps were used by Telarc Digatal....he advocated use of mosfets, and came up with diy amps such as the zen, and the aleph series, mosfets, mosfets have the input resistance of a tube and output resistance characteristics of bjt's....
so which of these are superior? only your ears can tell!!!
It has been interesting discussion comparing tube and SS. What I can see here as part of the problem in this comparison is the difference of technology before and now.
Before, we just have analog devices from the source to the speakers. All these devices alters the signals in the path - either as losses or amplifications.
Now, the only analog path that may remain are just the main amp driver. The CD/DVD, the DACS, and preamp may now all be digital, feeding the MAIN amp.
Whether we like it or not, we will not prefer a flat-sounding amp - it is dull and not exciting to listen with - and flat amps are generally for studio purposes. What we enjoy and run after are those amps we will enjoy hearing. Talk about marantz slightly laid back implementation is in itself an introduction of distortion to the original soud (you may call it equalization). The Denon is much more laid back than marantz - it is their sonic signature of Denon distortion - so goes with pioneer being bright or the NAD being soft or Yamaha somewhere in between with any of these.
Tube is basically 3% THD. It has soft clipping. These are distortions to sounds. Talk about sweet sounding even harmonics present in the sound makes it listenable - but it is not supposed to be there - thus it is distortion.
Basically, all SS amps (any brand) are almost identical linear (this is in fact the design concept of linear devices such as transistors). Their main differences is their signature distortions (equalizations) introduced in the preamp level. Further, your respective CDs like ARcam, HK, NAD and so on (if you use the analog line out) also provide another point of distortion (equalization) to maintain their signature sonic balance which has its own audiophile following.
Tubes, on its part has transformers in its signal path - it is an inductance in the signal path - and low gauge of magnet wire - which I deduce somehow explains the limitation of high frequency (because of inductance) and low frequency (because of gauge) - resulting in a minrangey sound. This is also distortion - and may explain the 3%THD typical of tubes.
So does tube listener enjoy distortion that why they loved tubes? I dare say yes! With the same reasoning, SS lovers loves distortions thats why they have brand following - av_phile for Onkyo, Others for HK, levi for Denon and others for NAD. anf all this are subjective preferences - and nobody can put his weight into saying tubes are better or SS is best.
Objectivity ought to have standards - and it is here parametric measurement will indicate superiority of SS in keeping signals almost unaltered (flat responses). but this is big deal to be made as basis for ones preference. Your ears, depending on your age level, type of your sonic balance, and music type you enjoy will dictate what amp to get.
Lastly, harmonics are sometimes very small issue (typically not audible) that is being magnified beyond practical terms by either camp.
In conclusion, scientifically and technically - tubes are already past its practical and economical life. but this does not mean that tube lovers should switch to SS - old technology can still thrive with the present though very expensive. This is why, tubes lovers are often referred to as hobbyist, and why debate about hobby.
akyat,
this is the third technology, first is the bjt, second are fet's and mosfet's, then this one, igbt's...this last one is nothing more than a combination of the two, it combines the very high input resistance of mosfets and the very low output resistance of bjt's..this device was invented for motor driving purposes and eventually found its way into audio....i haven't even touched this device yet.....

as before, new technology is always met with so much enthusiasm, whether it can live up to expectations is another thing, me i'd stick it out with my leach amps....
Anyway what Solid State amps are you talking about? Does it include the common receivers like Pioneer,Marantz, Denon, Onkyo, Yamaha or Harman Kardon? My receiver is a solid state and very good sounding but its a far cry compared to my ordinary vintage tube? I dont think that Im just appreciating distortions because I have been using solid state ever since and I know what is good and bad. I did not try tubes if I was not impress with the sound. Im not referring to the high end solid state but Im just comparing a vintage amp to an average receiver. Aside from all the technical explanation which doesnt prove anything that it would translate to a good sound, why is it different? Listening and enjoying is different than reading and be fascinated by the specs. Guys any experience owning and listening to a tube amp for a long time?
Ako I have a question.
What is the benefit of using a Torroidal Transformer in an amp compared to conventional transformer lang?
I've seen the Musical Fidelity of Narayan yesterday and inside you can see that it has a torroidal tranformer.
nels76
these are very good links. informative but a bit too technical. ??? so where do Leach and Gain fall? (?Fet or bipolar or whatever)...
btw, thanks for offering the cheaper in hifi enjoyment. :)
joan/arni
If solid states are the way to go, low distortion, solid state devices sounding the same...etc
When a designer uses feedback to make his amps stable or sound better....I think he is not a good designer :-X. Feedback causes a lot of newer problems....I think Matti Ottali some time in the 70's wrote about this....only THD measurements improve with feedback...not sound. :'(
Why are the Vintage Mark Levinson, Krell, Hi-end Accuphase/ONKYO, which were built with the best component (transformer, caps, heatsinks) ...only being used as book ends ;D now....in short not listened to.
Maybe you fixation with solid state being accurate and low distortion over rated.... :o
Maybe solid state design have inherent design flaws to begin with. Push pull for one splits the signal somewhere...then recombines....that is why Nelson Pass abandoned his Threshhold Design for his single ended Pass. It think that push pull if you like loud sound!
The Gain Clone is nice because it is cheap...but the number of components inside the MONOLITH Integrated Circuit is a lot and very complicated....such as you basic IC. What are your comment on Integrated Circuits versus DISCRETE? ??? ???
If tranformers are colored, why then does a hi-end company like ROWLAND RESEARCH always use transformers(JENSEN) in all their products ;D.
For that matter .....most Professional Studio/MIKE/MIXING amplifeers...have transformer...and even tubes...
During the recording process, I believe a lot of the music is damage/lost >:(....maybe you need a device to reconstruct what has been lost...something additive...even tube/transformer distortion! ;) :-*
gainclones were made (the japs are very fond of this!!! remember the AN214 chip used on Pioneer KP500 car Stereo that is still sough after today?)
I am not here to debate either, it just irritates me that there are some internet gurus who spread false info...now how do you have a push=pull circuit from input to output...that must be some cicuit! how many stages....? Please share this fantastic cicuit....
hope this satisfies your curiousity:http://users.ece.gatech.edu/~mleach/superamp/circuit.pdf (http://users.ece.gatech.edu/~mleach/superamp/circuit.pdf)
and this:http://users.ece.gatech.edu/~mleach/superamp/ (http://users.ece.gatech.edu/~mleach/superamp/) you can learn more about the author here:http://users.ece.gatech.edu/~mleach/ (http://users.ece.gatech.edu/~mleach/)
Maybe I am wrong, but it seem that this amp has a differrential input (as the link says), then it now acts as a single ended from the voltage stage, to the driver stage ;). Only at the OUPTUT Transistors will this amp act as a push-pull. Maybe you should say you want your push pull amp to have a symetric circuit in the voltageand driver stage-not push pull.
The problem with these solid state amp are that they manipulate the signals too much, they split the positive and negative half of the signal (at the input differential stage), then amplify it in the next stage, then amplify the current in the predriver, then recombine, all this with the injection of some feedback at different stages.
Realistically, when you inject feedback after 2-4 stages back to input, won't there be a phase shift/delay of the signal. Just think about that. ???
Every electronic device, whether tube or ss, will manupulate a signal. Every gain stage has a phase shift time delay introduced into the signal. The designer has to make sure that the signal rides well with the alterations within the tolerable limits of passive and activie devices and that the reconbined positive and negatives halves of the amplified signal in a push-pull configuration has the least crossover distortion at full amplificaition and is virtually identical to the input signal (except amplitude) before sending it to the speaker voice coils.
Crossover distortion is crossover distortion...only true class A biased amps avoid crossover distortion. Crossover distortion occurs when the transistor switches on or off. This occurs in the very low voltages. When you play loud volumes (which I don't often) the delicacy of the music is masked!
You are correct every stage has manipulation and phase shift, but just imagine an overall feedback from output to input, after the inherent phase shift of each stage!
Tolerable limits of components? So in short a designer designs his amp to sound as least colored and accurate as possible! Now this least colored and accurate sound is according to his taste! His personal taste.
Paul Macgowan (formerly of PS Audio) wrote that by biasing transistor to heavy or light will result in faster or more euphonic sound (tubey).

sirs, when i look inside my amps, i see a plastic knob labeled "BIAS ADJ"... i assume it is for adjusting the bias? how does it affect the sound?

joan/arniYou maybe right but note THD (total distortion + noise) has been improved. But looking at tubes, at 3% typical, SS could be technically a lot better. If there is problem on feedback introduction, I guess, with techniques, same can be overcome.

Heck, even crossover networks inverts the signals, 1st order is 90 degrees out of phase, second order is 180 degress, etc.
But that's precisely why transistors make very good switching in a push pull operation. As switching devices ss wins hands down over tubes. Ever heard a push push tube amp attemptng to give large sonic power with equally large crossover distortions? But not other tube types like pentodes in push-pull configuration.
We can debate all the various distortions a ss device can introduce. But at the ouput stage with massive 300 watts RMS of sine waves with only 0.001% THD and IM at full power, I simply can't raise my eyebrows high enough. At even half that volume, i'll be more bothered with the windows and walls rattling than any electronically induced distortion in such quantities.
;D I remember those! I have a boxfull of those chipamps back then when I get request from "jeepney" drivers who wants their KP500 repaired. Majority of the AN214s failure is due to output short! Human error eh.
JojoD
Now do I need 200+ watts or more efficient speakers ?

Av it seem that you are very fixated ;)with 200++++watts(what is the efficiency of yor speakers? ::)). There was an article in STEREOPHILE, it was a Sam Telligs (spell?) column, that the european and english solid state amp designer agree that parralleling output devices (transistor/mosfet) results in sound that is not as good as single (pair for push-pull).
86 db/watt speaker
at
1 watt = 86 db
2 watts= 89 db
4 watts= 92 db
8 watts= 95 db
16 watts=98 db
32 watts =102db this is pretty loud now! :o
That is why the NAIMs, UNISON research are abt 40-60 watts only.
If all designers follow only the device manufacturer exact operating parameter, 2 things
1. All amps would sound the same!
2. The manufacturer would make the best sounding amps! Eg. Hitachi, Toshiba, etc
I am not saying saying that one design is superior over the other, audio is an ART, the designer is an artist, I do not believe that the good designer follow the manufacturer specification exactly! They only use it as a staring point, then they change it, run it in the upper have of the linear operating range, or lower range of the operating range. Biasing it too much or too little or just right.
It is like food, the mixture of all the ingredients is the key. Then who is tasting it, if it is a thai-not enough spice, if british-too salty!
Now the question about accuracy and transparency is that who is correct, the solid state or tubero, I think it is the one closest to live music or the perception to live music. Is lower THD equal to live smaller difference to live sound.
Now do I need 200+ :'(watts or more efficient speakers ::)?
And like anything else, there are well engineered amps and lousy ones. The artisitry comes in in the design of the how the amp looks like, not how it performs.

av_phille,

how true!!! take the case of the legendary Dynaco ST70, David Hafler designed this amp with only one consideration in mind, that is to make it cheap and sell it cheap!! that it has become a legend that it had become today is something way beyond his wildest expectations!!!even the most expensive components on the planet can ever fool me!!! because the moment the mics pick up the signal, distortions and colorations already begun!! and to think of the many processes that had to be done before the reproduced music reaches your ears!!!
so what to do?
just enjoy the music in the knowledge that it is just a replica of the original, if you can accept that, i believe the better will be your enjoyment of the music!!
I am very disappointed that you stated that the only reason the Dyna ST70 is still alive and strong is because it is cheap. I guess all the ST70 users are deaf. Give more credit to the longevity due to the sound. The Mark Levinson ML2 or ML3 (designed by Jim Biorgiono) or the AMPZILLA (also cheap). I don't think any are still being used as their main amps, as sub woofer amps maybe! Just think why? These amps have all the specs that you want wattages, current, flat response.

and may i also add -- its price is going up as it gets older, not going down like most amps. is that correct? if true, then its a testament to its staying power. can't say if i'm too happy with that scenario, coz now i can't afford it. but i'm happy for the owners coz its going up in value.
I agree 100%, the moment the mike, a tranducers converts the mechanical sound waves in to electrical signals distortion mostly due to losses occur. Dynamics, small artifacts and all. Maybe you should consider the possibility of the need to add some distortion back in order to "restore" what was lost.
Sorry, but to even think that addting distortion in the playbaclk process would somehow restore what was lost in the recording process is sheer anathema to a hifi purist. But go ahead, like i said, enjoying the music often has nothing to do with hi-fi.
i suspect they purposely add distortions to the recorded music to make it sound attractive to would be buyers, compression is common so that music plays very loud or so it seems....
this thread is a sensible undertaking, giving options for other audiophile to enjoy clean music at so cheap a price and enjoying the fun of building it themselves.
There are more differences such as slew rates, rise times, THDs, noise floor, frequency response, microphonics, etc.
But what you are suggesting is in fact being done - allow more power bandwidth so that the onset of clipping beccomes unnecessary at listening levels. Many audiophiles actually shy away from modestly powered SS amps which is basically the province of entry level stuff and go for those that give at least 250 watts RMS per channel with instantaneous current handling capability reaching as far as twice that. Clipping is almost never reached at half volume or more for either continuous and peak signals. So get the most powerful SS amps you can buy and enjoy!!!
when the BIG boys talk, small boys (like me) listen and enjoy and learn. candid and healthy exchanges above surely educate. :) :) :)
Akyat, good idea: Leach and GC shootout or even just audition. I won't miss that thing.
we fall, we stand up, we try something new.
well fall allright--at least I did big time. I blew the midrange drivers of my speaker testing my d**n GC--zapped it with 25V DC ;D despite taking advice from Joan2. Oh well part of the fun I guess.
Sama ko dyan! Want to hear Leach perform too. As I also don't have strong preferences or conviction about tube vs. ss, it would be nice to hear din how it fares vs. tubes. Just an idea though.
...The differences between one amplifier's performance and another's, although easily measurable, are almost always inaudible. Even the minority of audiophiles who claim to hear variations from one amp to the next have to work very hard to do so....
Are there any truth to this statement? Are we going to hear differences between the Leach and the GC? I'd like to build one GC, with the help of someone, of course. Pwede bang pagawa na lang, di ako magaling sa electronics eh?
joan2,
I am interested in building the leach amp..... 8) 8) 8)How can you help me on this??? ::) ::) ::)Thanks....
Are there any truth to this statement? Are we going to hear differences between the Leach and the GC?
forgive me kung medyo OT itong itatanong ko. i like to know if this is an a/v receiver amplifier section problem:
after a power failure there's some power fluctuation and the receiver stops working. the lights on the receiver were still working including the LCD except an "OVERLOAD" word scrolls across the LCD. each time you press a button "switch off power" will be displayed on the LCD. there's no sound whatsoever the receiver is crippled.
receiver was brought to a (stupid)repair shop and was diagnose with 3 damaged amplifier modules. the modules was ordered abroad which cost an arm and a leg but after replacing the supposed broken modules the receiver is still not working exactly as before.
could it be the amplifier section? or could it be the overload protection circuits? but why didn't it reset by itself? can the power fluctuation damaged the overload protection circuitry that easily? is the overload protection circuit easy to fix?
any help will be appreciated.
kaya matutuloy lang ang shootout pag may maglalakas loob pagamit ng speakers hehehe.
Hi,
I have one of those Low TIM Leach Amps here: http://www.geocities.com/jojod818/leach_amp/leach_low_tim.htm
I currently use this amp and is really a very good design. The sonics are excellent too.
JojoD
ako din... mas gusto ko magpagawa na lang sa expert kaysa gawin ko ng sarili... if the price is right.
about amps sounding the same, i don't quite agree with the article cuz i have 5 amps and i do hear a difference. even equal-powered amps have a difference in tonal balance. the thing is... some amps will sound the same and some amps will sound different. for instance, when playing vocals or guitar it may be hard to distinguish the sound of the luxman lv-105 from the marantz sr7300. but play something with a double bass, and you will hear the difference in bass definition. sony 333es and sansui a707 are bass-heavy with soft treble. onkyo 819rs has sharp treble. how did i compare? with great risk & difficulty!! i was able to switch back & forth between 2 amps because my dvd/cd player has 2 audio outputs. i connected 2 amps to 1 speaker pair and switched between amps making sure that the speaker switch of one amp is on while the other is off. dangerous isn't it?? don't try this at home folks. its hard to resist when curiosity starts to itch.
if you set them up using the same speakers, same gain, same volume level, same equalisation, same program material!!! i doubt it!!!!
i see... so this means much of the sonic signature actually comes from the preamp?? i can see how my integrateds can sound different, they all have preamps. that's giving me something new to play with -- preamps!! pero mga sir, does this mean that tweaking an amp is useless? i thought replacing certain parts will improve it.
You hit it right on target!
I remember reading something like this, a shootout of amplifiers including tube amplifiers. But they made sure they are on same loudness level and some other adjustments on each maybe as permitted by their respective tone controls probably. Then they commissioned select and seasoned audio personalities to identify which is which. All claims just returned to ground zero.
Most of the time, it is the pre-amplifier components (pre-amp and phone/tape/CD decoders) that forces the differences of amplifiers. I tried this with my own setup.
I have a high-end integrated which has selector to bypass pre-amp and connect straight to main amp. Being integrated, it sound the balance I like. I have a separate AVR which I dont like the sound balance in music. This AVR has pre-outs though. Out of curiosity, I fed the pre-outs of my AVR to the main input of my high end amp. What I got is the sound balance similar to the AVR amp sound balance that I dont like.
So it gave me the impression that the amp of my AVR and the high end is (almost) the same. The tonal balance that dont satisfy me is basically coming from the preamp of the AVR. And the tonal balance I like from my high-end is coming from its own pre-amp circuits. The amp of both is basically just that - reproduce faithfully what has been altered by respective pre-amps.
The theoies as applied in amplifier design should result in amplifers sounding the same across many vendors. But because of design compromises in many commerical amps, among other things, sonic differences often result. I have come accross a couple of amps in the past the don't sound the same at any volume level even if they have the same circuit topologies and power reserves. What I heard was confirmed by an oscilliscope and a signal generator.
One school of thought suggests that the difference begin to be audible once the threashold of clipping begins. That's because distortion is a form of sound coloration. And different amps have differnet distrotion traits.
It's also possible that interchannel crosstalk is high in one amp courrtesy of some unbalanced grounding conditions that allow the left signal to leak into the other resulting in less stereophonic imaging.
Most of the difference I heard are in the extreme ends of the audio spectrum, where one has deeper bass or the other more pronounced cymbals. Often the culprit is in the preamp stages where the tone control flat settings are not really flat. Or some capacitor in the audio path that restricts frequency responses. I think transistors also account for some sonic signatures, mosfests vs bipolars vs germaniums vs JFETs vs integrateds, etc.. Theoretically they are supposed to give the same bandwidth albeit under different ccircuit parameters. But I think some give high bandwidths that can go to 100khz which could allow the high harmonics of instruments to pass through, giving them certain sonic qualities that otheriwse would not be heard.
If the amps don't have the same power reserves, it's possible that you could hear differences during transient peaks where one starts to distort while the other doesn't.
At any rate, while I would like to think all amps using tried and tested design pricniples should sound the same, it's often nice to now that difference can exist to justify upgrading. he he ;D But among well-made hi end amps that are accurate, I think differences can be so minute as to be inaudible.

sir joe3rp, you mean to say we should not be looking for high powered amps with low distortion ? what should we look for as an alternative ? i listen at moderate levels most of the time so i guess i dont usually need high power, but once in a while i like to listen to rock music at very loud volume. its that 5% of the time that i want to rock that made me upgrade my speakers because i could never enjoy that 5%, though 95% of the time i loved the sound.

That doesn't sound very friendly sir ;)

whats so special about an nec amp? wala lang just saw an nec int. amp and checked out its specs sa net, its dual mono, 60w per channel and has and amp in along with a preout. it uses jfets acc. to the site i checked.
Though the model is old it has some interesting specs.
Just wanted to get some feedbacks. anyway i'll be tryin them out.

well its an nec a10x ;D
'straight wire with gain' this site gives some explanation:http://www.weldon-northants.fsnet.co.uk/Hi-Fi%20-%20Amplifier.htm (http://www.weldon-northants.fsnet.co.uk/Hi-Fi%20-%20Amplifier.htm)
And if you think of it, if the SCOPE is that magical tool, why doesn't TEKTRONIX, Hewlett Packard, HITACHI, DUMONT, and other instrument makers make the best sounding Amplifiers? I would think making an amp or pre-amp would be easier and a lot cheaper to make. And the market would definitely be larger.
I am amused at that part of the article when the author asked the heckler if she can ask the conductor to play quieter.
joe3rp,
are youthe same joe3rp in pinoypc? just curious,
i remember i traced the cicuit of the Hafler XL280, another great amp from the late david hafler!!!
your tips about auditioning and buying audio gears is really cool!!!

if you liked your luxman, then you know the answer, hindi na maglalalayo dyan!!! actually 'a straight wire with gain' is also applicable to preamps... it is just the source and the speakers to think about....there are audio purist's who does not like tone controls, equalizers, or anything that may be construed to alter the character of the signal, i have not heard such a system myself, just read about them!!! tube pre-amps driving a ss amp is also possible, i had a client once who owned an Aragon power amp, driven by an Acoustic Research Tube pre-amp!!!
i do like the sound of the luxman. that's why i was wondering if it was the tubes that made it sound good. it basically sounds like my marantz receiver, w/c is pure ss. both amps sound smooth & sweet, with relatively lean bass. but luxman's bass is tuneful & detailed despite being lean, so it was my favorite amp until it broke and i got the sansui as replacement... luxman vs. sansui -- now thats one shootout i'd like to hear. its like a contest between detail vs. scale, microdynamics vs. macrodynamics. sana maayos na...
psu question.
i built one. AC hits accurately but after fullwave rect, DC hits higher volt. for example, AC=6V; DC becomes 9V. I don't think this is expected. any tips, please? thank you.
in that case, should i tap AC at 4.5 or 3V so I hit 6VDC (reqt of the device)? or this is nothing to lose sleep about... di naman kaya ma-damage yg device? salamat!You could if you can get a transformer with that secondary voltage. Or you can use a regulator, either an LM317 or 7806 to tune the DC to 6V. I actually use a 7806 for my tube filament. After the rectification, I have filter caps of about 200uf before and after the regulator. Like this maybe?:

mga sensei, is there a universally accepted standard voltage for CD/AUX inputs? what about power amp inputs?
in my marantz receiver there is a peak indicator that lights up when i'm feeding it too much signal. the sound gets harsh & distorted when this happens. it happens only if i play an audiophile CD with my x10-d connected to the analog inputs of my receiver. i suspect that since the x10-d causes the sound to be about 2db louder, it is somewhat amplifying the signal. if i play a CD that already has a high signal level (like audiophile CDs), the peak indicator lights up during musical peaks. strangely, my sansui amp doesn't distort with the x10-d. does this mean that the sansui has a higher maximum input level than the marantz?
Reads like the Rotel RMB1066. Excellent by any standard.
Wow, am impressed at your familiarity with Amps specs! That is RMB 1066 indeed!
Rectifier questions:
1. Pros-Cons of tube vs SS rectification
2. Pros-Cons of Half-wave vs. Full-wave rectification
How should Schottky (spell?) be classified? What about fast-recovery diodes? Pros and Cons of those?
Yup, Try feeding the x10d output to the main in of the marantx rathe than the line in. This is where matching becomes an issue. Some amps will overload wen fed with higher than expected rms votage at the input. Others wont. I strongly suspect that because the x10d is a buffer preamp that could have a gain higher than unity at the output, it is better connected to a main amp than to another preamp which is the case when you use the line level input of an integrated.
thanks for the responses mga sir!
i have another question: i have a power amp with an attenuator. well actually its my sansui integrated amp w/c has power amp main ins... when i switch to the power amp input, the volume control becomes an attenuator.
- will the signal be degraded because of the attenuator?
- if i set the attenuator to max (or +0db), is this equivalent to a direct connection, i.e. no attenuator at all?
i've seen the back of some attenuators... they're filled with resistors. do the resistors affect the sound? does the maximum volume level have no resistor so its basically a direct connection?
many thanks!
I thought so too! the x10d is a preamp, and has higher output than the LINE IN requirement standard of typical amp. the output of x10d is best applied to MAIN-IN based on its output and probably based on its output impedance (and input impedance of MAIN-IN of the amplifer).

if ur willing to get ur hands dirty, u can try a potentiometer to reduce the output voltage of ur receiver to suitable levels.
here's the schematic of the attenuator. it will provide an output range from 0 to approximately 1/10 of the original signal.

why are there balanced and unbalanced inputs? xlr's and rca's? what specific applications do they have?
sir iceman, sent u pm.
Hi joan2 and homer,
do you know a store where I can buy Black Gate capacitors? ;)
imho, balanced cables uses 3 wires, 2 for the signal 1 for ground and shield. xlr connectors are often used with these cables. due to their greater noise immunity, they are used for carrying low level signals or long cable runs.
unbalanced uses only 2 wires, 1 for the signal and the other for ground and shield. rca connectors are usually used.
to make it short, go balanced for lower noise, unbalanced for lower cost.

hello guys...dunno if this is the right thread but hear it goes :)
if i would bi amp a speaker using the pair sorround(say +and- pair would go to tweeter) amp of my reciever. my amp is rated@80w for all channels(L,C,R,RS,LS and SW)...and my speakers are rated 30-100watts...im just worried that i might overdrive the tweeter ???.
I fail to imagine your planned connections. Bi-ampling requres separate amps fed to your tweeter and woofers per channel bypassing the spekaer crossovers by using electronic crossovers between you preamp and power amp. And the same signal should be fed to those amps. A surround receiver will get different signalls for each amp. So if i got you correctly, your planned connection will drive different signals to your tweeter and woofer.
Hi homer,
thanks bro.... will these sprague and jackon electrolytics better than the stocks? electrolytics deteriorate thru passage of time thats why I need to replace some twins to get a cleaner sound... :D :D
Hi Julsp,

... all i can say is 110v is definitely less painful.
to transfer the same amount of power at half the voltage, across a transmission line, you will need to double the current capacity.
will higher current capacity translate to better sound repro?
will higher current capacity translate to better sound repro?
what is the appropriate oversizing of a transformer relative to an amp's requirements? this is based on the assumption that a circuit should be in a better position to have excess power reserves than short of it. 2x or 3x? any problems with excessive power reserves, like would it cause humming?
heard about sad stories of gear breaking down to due to cycle incompatibility. how do we know which cycles our amps should feed on? is this related to voltage standards (110 or 220 )?
Gear that has motors in it and derives its speed from AC lines will be affected by frequency, but will not in any way destroy the gear...

Thanks sir JojoD kaya pala mahal just check the net and was surprise of its price us$100 a piece for 4700UF +-20%, 50 vdc. Was interested panaman kaso at 100 bucks a piece x 4, di bale nalang....secondly 40mm yung size niya and my amps use only 20mm...
Thanks again...
Hi,
Tanong ko din ito, dati kasi nag-assemble ako ng 75W per channel stereo integrated amp, using a metal can power transistor (J9555 yata yun, limot ko na tsong). Para saan yung "trim pot" banda sa input ng power amp? ang alam ko para sa gain yun pero paano ko malalaman kung tama yung setting na yun?
Uy, thanks.. MJ2955 nga yun, limot ko na rin kasi dahil 1997 ko pa ina-assemble yun at medyo no practice na tayo sa electronics. I'll try to post the schematic, sana nandoon pa sa files ko yun kasama ng mga alexan electronic kits ko ;D ;D
this Q is intended for Jojo - the DIY master....
bro, how do you rate this power transistor:
Sanka 2SA1295 and 2SC3264
what would be a good replacement for this brand and what does SA and SC means?
thanks
coffee nga pala yung Sanka... Sanken pala yun.... hehehe
thanks a lot!! ang galeng mo talaga bro... pwedeng pwede na maging professor ng Electronics 101. ;D
At half or full volume, receiver's pre-out level can overdrive the amp beyond clipping. Just be careful with your volume setting. Perhaps a 10 o'clock position is max.
Why are VARIAC's good (or otherwise)? ???
Bro welcome back! ;D ;D
i didn't get an answer from the other thread, so i decided to post it here which is the proper forum:

kenwood does not make capacitors, they order them from elna, nichicon, etc with instructions to put kenwood in the label.
caps, need not be replaced at once, you should inspect them for leaks, or bulges, check also the rubber seals to make sure they have not gassed up! caps with these obvious defects needs to be replaced at once.
the big can reserviours as the brits fondly call them can be reformed if the equipment has been idle for years. but if you are able to power up your gear without incident, then let is sit powered up for a day, turn off for a day, them turn on again, repeat these cycles until you are satisfied with the sound.
here is a good japanese site illustrating such rebuilts involving caps and etc...have fun!
http://amp8.com/index.htm
caps can be reformed and the leakage current after rated working volts is reached can be used to judge if the cap have to be replaced, anything less than 1mA is a good figure~
OTOH, if you have money to spend, why not? and throw in some polyprop caps as bypass, you may yet be in for a surprise!
Sir tanong ulit yung bang electrolytic ay pwede palitan ng ibang type ng capacitor bastat parahas lang ang value ?
Since class A amps generally run hot, is it bad to continuously run the amp in this mode? Would it fry the internal wirings/capacitors? I usually switch amp to class A and AB due to the heat it generates but if given the choice i would rather run it always in the class A mode. Pls advise. tks
tube amps run very hot also!
to me, a hot object that can be held for say six seconds is not that hot! less i would think twice!
Kung makapal ang balat sa kamay at may kalyos, tatagal pa. ;D
master Jo, ano ba yung mga tinatawag na complimentary transistors? ano pagkakaiba ng mga BJT at MOSFETS o FETs? tenk yu :)
what is turnover frequency?
it is the frequency wherein the boost or cut action starts. the time constants formed by capacitors and resistors in the circuit determines this.
So what is (25hz, 50hz, 100hz)
It sounds very nice (to me) when the tone controls are used and imho that is what matters
in layman's terms, if you use the 25Hz knob which has a center frequency of 25Hz, your max boost of +10dB will only affect frequencies up to 100Hz since it's F3 is 100Hz.
happens to frequencies below 25Hz
Hello Sir JojoD,
Thanks for the explanation. To my [layman's] mind, your and sir 2ny's explanations agree with each other. But your post has made me wonder what happens to frequencies below 25Hz. Are they not affected at all? Or maybe what happens to the left side of the center frequency of 25Hz is a mirror image of what happens to the frequencies between 25Hz and 100Hz?

It has no signal coming out except for a frying sound.
SANSUI QRX 3500
I have a Bi-wirable Speakers and a solid state amp with output for speakers A & B. THis is my Question:
- The amp can set the speaker output to A + B is it possible to bi-wire the speakers using A output on Highs & B speakers on Low of speaker? ???
Is there any signigficance on this set-up? I believed polarity of speakers is very important because speakers though bi-wire they share same PCB circuit for the cross-over (Common Ground).
Anybody tried this set-up? Your reply is greatly appreciated.
Ask ko nalang dito, para hnd na ako gumawa ng bagong thread :D
1. If i have a digital amp. Lets say a Denon 1602 or Yamaha RXV-795 . . 5 Channel sya diba ?? Can I seperately Control the Volume of each speaker ?? Kunwari yung Rear Left speaker ko, masyado mahina. Pwede ko lakasan ??
No problem with this setup. I did it before with my receiver RXV1400 and for my speakers JBL LX2002. The result was more detail, better soundstage and imaging for movies. For music, too detailed for my taste (masakit sa tenga minsan). I still have the speakers and the amp today.
Okay to siguro kung separate yung HT setup from your Stereo/Audio setup.
Wala namang pumutok or nangamoy...hehehe.
You have to try it of course to see if you will like it.

question is, pwede ba ako mag bi-wire kung ang speaker ko ay 6 ohms na wharfedale 9.5,hindi po ba puputok yung amp ko

No problem w/ that. Isang pair lang naman gamit mo. Biwiring is different from using another pair of speakers (A+B).
Ala naman additonal speakers so there's no additional load. 6 ohms pa rin makikita ng amp.
I think A+B assumes speakers will be used in parallel. If so, Use the ff formula:
Effective impedance= 1 / ((1/impedance1) + (1/impedance2))
So, if you use 2 16-ohmers, you get 8 ohms w/c is what the "A or B" config recommends.

afaik amps produce the spec stated frequency range. tama ba? ;D
have u rechecked all connections? speaker fuse?
subukan mo muna hook-up another amp or your t-amp with cv speaker. siguro naman maski sa t-amp meron woofer cone movement ma-notice ka since 95db CV.
pwede din hookup the denon int.amp with another speaker to check if it drives the woofer of the speaker. at kung may problema amp usually tweeter ang tinatamaan ng clipped signal. hinay-hinay lang sa volume while testing :)
it could also mean that your subwoofer amp died....that is why no low frequency sound... :'(
This happened on BOTH channels at the same time?
Did you switch speakers from another make? Same thing?
Can you plug a headphone and see if there's no LF still?
This happened on BOTH channels at the same time?

Are you sure the woofers are already dead? Check them on another amp?
With bass coming out from a sub connected to the amp's pre-out, that means the preamp is fine.
If the woofers on both speaker sets are dead, your power amp section seems to be on a killing spree. ;D The best way to fry a woofer is to impress a high DC voltage for a few seconds or a low DC value at extended periods. This could happen if the amp leaks DC current. The tweets and mids won't be affected because their high pass crossover filters essentially blocks DC current. No such thing with woofers which use low pass filters that allow DC current to pass thru. So it's now a matter of troubleshooting why the amp is bleeding DC. And how both channels do it at the same time.
pleasant goodday guys,
ask ko lang if it is possible to assemble my own solid state amps even if i am a non-technical person?
How much kaya to assemble one and where can i get the parts?
thanks!
sirs,
would replacing all the transistors (assuming that the replacements are all of the same value) alter the general sound characteristic of an amplifier? my amp has a slight hiss on the right channel even though the volume control is set to zero. im thinking of having the transistors on the left and right channels replaced. would it be an overkill, considering that only the right channel has a hiss? thanks in advance for any answers. :)

what makes a solid state amp sound tube-like? (without adding a tube preamp/buffer/stage of course ;D )
i usually read comments on some brands of s/s amp sounding like tube amps, especially the vintage ones. is this true? can one design a s/s amp to mimic the sound of a tube amp (or maybe vice-versa)?

I still have to digest that thing "accuracy". Of course, tube injects those even harmonics, SS injects those (they say) odd harmonics.
From the standpoint of measurement, SS is more accurate (by the definition of current instrumentation of THD measurement). But whether the present instrument were really designed to measure some 'odd' artifacts in the traditional SS technology, seems to me more of a debate in my mind that I am tracking down in the internet.
When I was deep into gainclone, these tiny workhorse was measured with both odd & even out - totally diff animal eh! I just thought, is this the more accurate than both? ???
Of course, transistors' characteristics are way better than tubes - how transistors were used to make an amp is entirely a different story altogether.
we can say Tubes are "personality oriented, change the tube, even of the same type but different make, and the amp become another person" SS otoh are topology oriented, the ss circuits are designed so that it will be consistent in operation and does not depend on transistor gain,(beta).
the tube sound good(subjective) simply because it has higher levels of 2nd order harmonics, which are minimised in ss amps.
I think, it is not only because tube have 2nd harmonics, but the best of SET are in class A! Even the link that you provided points to the fact that SS in class A can have comparable sonics
class A has inherent low levels of distortion, tubes or ss. but since ss amps are almost always in push-pull, while SET is single ended, right there lies the difference. ;D
... so if you want 2nd or even order harmonics, then use tubes, single ended of course... ;D
The soft clipping nature of tubes driven to clipping results in smooth edged square waves that give rise to more 2nd order harmonic that can enhance the signal. Whereas SS hard clipping results in sharp-edged square waves the give rise to strong 3rd-order harmonics that makes the sound harsh.
On a curious note, don't tubes also produce 3rd order distortion? How is it possible for tubes to produce primarily 2nd order distortion?
Meron bang "breadboard" na puro butas lang? To hold the components tapos P2P sa ilalim?

questions:
1. what do you mean by the different numbers in the specification
2. i am planning to buy a floorstander, probably a wharfe 9.4 or 9.5 or evo, can my amp drive these based on the above specs.
3. are these specs real, the amp is made by teac of japan.

i'll look again this evening. but this morning all i saw was 100-240 watts. nothing on consumption.
the higher the better or the lower the better?

It seems that this very controversial issue is again on. ;D
...our hearing is imperfect...
True, I am 54 years old and I do not hear anything above 16 Khz anymore.
But our hearing is also a miracle. We are able to analyze a single sound wave in its original components.
When we listen to music we can distinguish the singer and the orchestra and the drums. But the actual soundwave is only one wave, the result of the interference of all the different sound sources.
And our hearing also filters out all unwanted noices.

"all Class AB amplifiers run in Class A for a small portion of the wattage (typically 1 to 5 watts) before switching to Class AB for the sake of efficiency ( and less heat )"
quoted above from one forum. is that true?
yes, and depending on quiscient bias, could be from 200mW to several watts, the drivers can be designed to operate classA while the output transistors classB, that is why the AB.
i say not to pay too much attention to this as there are lot more considerations than class operation alone..it has a lot to do with design and circuit topology... ;D
back to marantz quarterA series- it seems that the jap manufacturers just magnified the class A from a few milliwatts/watts to 1/4 (quarter) of its rated power (rms).
Hi Sir Tony,
Tanong lang po.
Given the attach picture, can my 220V amp be converted to 110V or 120V if I will be using it in 120V country without a need to buy a step-up transformer? There is a schematic on top of the transformer but I do not know if it is for voltage convertion. Can an ordinary technician do this tweak?
BTW the amp do not have a voltage selector that is why I am asking.

Does this mean that the torroid is somewhat like to xformer in 1 casing if there are 2 primary winding?
it is not unusuall for japanese amp makers to do this, since by doing so, they can hit markets anywhere in the world, all they had to do is change the power cord and change the taps. you are lucky to have one amp such as this. ;D
bigla akong nag-isip. Pwede nga pala yung NEC A10-II ko na dual monoblock, i-series yung 2 transformer, then I can use it at 220 na. What do you think?
go ahead, make your day! ;D but remember also that native jap amps are rated 100volts, i wouldn't hesitate doing it on my amps, but for others, some word of caution, if your local volatage goes over to 240volts then proceed with extreme care... ;D
Wow mag sirs, thanks! yung Pioneer SA8800II ko na dual mono pwede ko naman gawin 220V pala. :)
Hi Sir aHobbit/Sir Tony,
Nalito lang ako. Is there always a 10% voltage buffer in transformers, the NEC and my Pioneer are 100V, if connected in series with the other 100V xformer will have an operating voltage of 220V? Thanks.
The increasing line voltage should not increase DC bias of the amp.

Gurus,
This is a cheap china made integrated amp. Before it was modded, the 4 encircled parts were not there. This is the only change done. Before these 4 output transistors (2sc5200/2sa1943) were added, this had the typical "raon" sound. After adding, the sound improved considerably. Why?
TIA
Ofcourse!... with additional 2pairs of OP amps will double the power. only drawback of this is the increase of the unit.... ::)
??? ano ulit yung drawback?

increase of the unit what?
be happy with the improvement, what you achieved there was that you doubled the SOA of the output stage......contrary to popular belief, power remains the same even with the addition of output transistors...... ??? twice the SOA means that even if your speaker's nominal impedance droops from 8 ohms, your amp can survive.
now why same power? ??? it's because you still have the same power transformer and the same rail voltages, so in effect, as far as power goes, nothing has changed, you just made your amp more robust with additional transistors, and that is good, the fact that you heard improvemnts is bonus!!!! ;D

Sir Tony,
Inisip ko ulit yung explanation mo - you are saying na wala dapat epekto sa sound yung modification. hmmm... di ko tuloy alam ngayon kung bakit na-perceive ko na better in all aspects yung sound.
Ginagamit ko ito with a kef 104ab. Nasubukan ko na itong kef with alot of amps and receivers-dito lang nagmatch. Tsamba lang siguro. Anyway, tama ka - just be happy with the perceived improvement ;D 8)
hindi tsamba yan, doubling the output transistors in effect lowered the output impedance of your amp, and therefore increased damping which could actually be responsible for the perceived improvement. ;D
it is not uncommon for manufacturers to come up with just one board for different models, yours could have a higher model, they just had to add in more transistors and maybe change the power transformer and caps, and there you have it.....this is consistent with engineering economy.... ;D
let us say your amp is rated at 100watts per channel, so at full power, with an efficiency of 60%, 40watts is dissipated by 4 transistors, so each one dissipates 10 watts, now adding another 4 more transistors, 5watts then is dissipated by each transistor....so in effect, while heat generated remains the same, the output transistors actually operate at lower junction temperature.... are you with me? ;D
there are other considerations....but remember power delivered is always dictated by the speakers and the volume level you listen with... ;D

Sir, ask ko lang, why some audio experts prefer just 2 pairs of output transistors in a ss amp? They say the sound is sweeter and more musical, though, at the expense of power. I also experienced this on some mid level integrated amps. It seems that lower powered amps ( around 20w/ch to 50w/ch) are more musical than 100w up amps.
Is there any electrical basis for this? Thanks. :)
Thanks guys and gurus! I guess I need to to a lot of reading about it. :D
eto ang stupid question...
My amp runs extremely hot... pwede ba ako magpakulo ng tubig sa ibabaw nito ? ;D
Bro -- subukan mo muna mag-prito itlog ng pugo.. ;D
pag tinopak ako susubukan ko ito..with lots of aluminum foil..hehehe
1. What is the difference between an amp and a pre amp? I hear the two a lot. ???
2. What are the pre outs of receivers for?
3. What is the difference between intergrated, power, and ss amps?
Maawa na nga ako :) .. Let me try to give a very basic explanation.
First you have the sources - DVD player, CD player, Ipod, whatever.
The sources are connected to the preamp-processor, or pre-pro. The preamp section acts like a switch for the various sources so you can select between them. The processor section manipulates the sound (provides volume control, decodes Dolby Digital signals, adds tone controls, equalizes, etc.) and video (deinterlaces, scales, etc.). Sometimes, the processing is done by the source itself (some DVD players have built-in audio and video adjustments) but generally, this is better done after the source. Also, the display has its own video processing (brightness, contrast, etc.).
For the audio, you then have the power amp. The pre-pro feeds a low-powered signal which it has taken from the source, which is then amplified by the power amp. From there, it goes to the speakers.
For the video, the pre-pro sends the video signal to the display, which can be a TV or a projector.
An integrated amp combines the pre-pro and the power amp.
A SS amp uses solid state transistors, as opposed to tubes.
Answering your qq:
1. "Amp" is a generic term and can actually mean preamp or power amp or integrated amp.
2. "Preouts" are found in some integrated amps. This is a way to bypass the built-in power amp and send the signal to an external power amp.
3. Nasagot na.
In addition, there are "receivers." These are actually integrated amps with a tuner (radyo). Most of the HT integrated amps have tuners so they are called receivers.
This is a very basic explanation and there can be many variations. Hope this helps. :)
The pre-amplifier is actually an amplifier also. The pre-amp amplifies the signals from an audio source - eg CDP, DVD, phonostage etc.
If you are referring to the amplifier as being a power amplifier, this device amplifies the signal from the pre-amplifier. The reason why there are several stages of amplification is due to device limitations. You cannot amplify from very low level signal to speaker level rail voltages without penalty. To achieve proper amplification, below are the typical voltage levels in a generic amplifier.
audio source signal (<2V) -> pre-amplifier -> (~8V) power amplifer (~60V)
1. What is the difference between an amp and a pre amp? I hear the two a lot. ???
2. What are the pre outs of receivers for?
3. What is the difference between intergrated, power, and ss amps?
Let me give you stupid answers:
1. What is the difference between an amp and a pre amp? I hear the two a lot. ???
- The Amp or Amplifier is a general Term can be "Power Amp" & "Pre-Amp" (Let me explain)
The Power Amp has no controls like Inputs or Tone Controls (For some Amp) Most of them have no volume controls
They are the units with SPEAKER level out
* When you connect your CDplayer directly to them they are set to maximum volume level no control (don't do it)
- The Pre-amp: From the word Pre means before the Power Amp. They have the controls for the inputs (RCA) sometimes they have tone
controls. They have Line level output for the Power amps sometimes with Headphone Jack output.
* Tone control - The Bass & Treble adjustments
* Line level output - These are the pair RCA outputs similar in our source (like CD-Player & the likes)
2. What are the pre outs of receivers for?
These are the analog out (PCM) coming from the 6/7/9 channels of your receiver if you want to put separate power amp or
Integrated amp . These can be done if you have bigger rated speakers that your Receivers can't handle (under power)
* PCM - Pulse Code Modulation (Analog output) Mostly ranging from 1 to 2.5 volt AC
* Under Power (Receiver Power output max. 30 watts and your Speaker rated 300watts minimum 50 watts)
3. What is the difference between integrated, power, and ss amps?
- Integrated Amp. Pag pinagsama mo function ng Pre-Amp at Power Amp they can now call Integrated
- Integrated amp Lagyan mo ng Radio - Amp Receiver na
- Dagdagan mo ng inputs ang Video - A/V Receiver na
* A/V means Audio / Video
- Power means the ff:
* Could be AC Power like 220V
* Could be Audio Power in Watts
* Could be Power Amp (see number 1)
- SS means Solid State (They are the term used for Transistor base amplifier
- Tube means the amp use TUBES for amplification like 2a3, 300B, EL34/84, 845 and many more
* They are all the same Amplifier
;D
Pls correct me if Im wrong, but isnt PCM (pulse code modulation) a digital signal? ???

is there a difference between the 2ch receivers sa multi-ch receivers aside from their available chanels?
...
it looks like na yung 2ch is more for audio use tama ba?
...
if so ano pros and cons ng 2ch receiver VS an Integrated amp for audio purposes?
Point of clarification lang:
PCM is not analog out. PCM deals with digital bits (binaries, 1 or 0, with voltage or no voltage type of swing)
PCM is not outputted in a pre-out. PCM is processed by processor in the receiver (decoded to analog form and fed to pre-amp stage). This analog form amplified by the pre-amp is the one either or both fed to built-in amplifier and/or outputted to the pre-out - thus, it is analog form.

My dream is to have a 120" screen HT with killer sound. I don't really care for the multichannel sound.
I suppose what the OP meant by "Newbie" is being new at HT. Though he's an "oldie" in stereo. ;D There are many like that. Many avid stereophiles who once shunned multichannels are now realizing what they're missing. ;D That's because they didn't give the same painstaking effort to optimize a multichannel set-up the way they did with their stereo gears. Because if they did, the proper multichannel project can be more than twice as expensive as the investments they've put into their stereo set-ups. ;D
Just to add another advise for multichannel HT use often overlooked by "newbies," is the aspect of tuning or calibrating the channels. It goes further than stereo in making sure you can optimize the enveloping surround sound as well as ensuring seamless integration between subwoofers and the main speakers. These things did not exist when using just 2-channel stereo. But take heart, having the Audyssey MultiEQ makes this aspect a breeze. ;D (But more expensive.)
BTW, what's wrong with Bose ???
The Audyssey must be really good, as it is highly recommended here. I think it works the same way as the Copland DRC 205 (http://www.divertech.com/coplanddrc205.html), which I already have in my 2 channel system. I am also a big believer of these products. Well, I had to resort to it because my wife will not be very happy with bass traps and room treatments.
Thank you for the replies. How much po kaya yung Denon 1508? I went to the shops in Mega and Shangrila - those carrying Wharfdale recommended Pioneer RxV361. Ok na daw yun for the size of my condo unit (36 sq mtr, but the HT will just be in a portion of it). Any feedback on this AVR, and how it compares with other brands?
iv heard yamaha 659 hook up with wharf fs di maganda para sakin un sound. :(
much better if u can do demo..
Thank you sir - Denon 1508 costs P 19,800 sa Listen Up Glorietta. Yung Onkyo 506, P 18,500. Halos pareho lang specs nung dalawa. Ano kaya ang mas maganda?
I play music 60% of the time and HT 40%. Ano kaya ang mas maganda sa dalawa with wharf speakers?
sir, may i recommend fresh of the line. a perfect companion to your system.
http://pinoydvd.com/board/index.php?topic=81351.0
Hi,
Im a newbie trying to set up an HT set up for my 36 sq m studio condo. I'd like to ask for help on an appropriate reciever to use. I plan to get wharfedale 9.1 bookshelf front speakers a center and a sub for now. rear speakers are under consideration and may or may not follow.
what are the reciever specs I should watch out for? and what brands and models would you recommend? I read about HDMI and upscaler recievers in this forum - what do they mean exactly? I have a 37 ' Regza TV, and I have a Toshiba HDMI player/upscaler so I understand it from that context. May difference din ba kung HDMI and may upscaler yung AVR o wala?
I got a recommendation to try out Yamaha RXV361 - I know this is an entry level AVR, but will this allow me to maximize my speakers? I listen to music a lot aside from watching movies.
Your inputs would be appreciated. budget ia 15 to 20 K.
Yung amplifier nyo ba ay naka kabit sa Auto Voltage Regulator?...Madalas po bang mag-fluctuate and koriente nyo sa lugar ninyo? ???
Baka kasi nag-spike and koriente nyo, tapos wala kayong AVR, possible po na ma-overload ng biglang pag pasok ng koriente sa amp. :(
Sir wala po ko AVR, kapag ganun b po b eh possible na sira na amp ko? nag o on pa naman cya kya lang after ilang minutes bigla mag o overload.
Good PM, Patulong lang po, last night kasi ung amp ko JVC RX 5042 eh ayaw gumana, lumalabas sa display eh overload and then nag o off na cya. I already try to check the speaker wire pero I cant find any shorted portion on the wire. :( Anybody could help me kung ano b ngyari sa amp ko? meron po b member na gumagawa ng 5.1 amp kung sakali...salamat..hope you could help me...

Welcome to Pinoydvd, bro. quepuco.
Are these the speakers you are referring to?
(http://www.satelliteguys.us/attachment.php?attachmentid=19050&d=1190314535)
You might want to try out tube amplifiers to match with those speakers.

Mga Bossing,
Help naman para sa bagong member ng PDVD :). I'm planning to buy NMT (thinking of either HDPro or Xstream) to watch downloaded movies from the net. Initially, I was considering a generic 1080p HDMI DVD upscaler (Xtreme or Nextbase) and then I came across this NMT stuff. Read several posts here and was convinced on getting NMT instead (thanks to the gurus of PDVD).
I have a Philips SP120 5.1 speakers connected to my old DVD player (ACE) via 6 rca jacks. I assume I would need a receiver for the NMT to use my speakers since NMTs don't have 6 channel rca outputs (correct me if im wrong, sobrang newbie pa sa HT setup). Optical/Coaxial lang meron sa NMT to use DTS 5.1.
What would you guys recommend for an entry-level receiver with HDMI? I have an HD-Ready LCD and planning to purchase an xbox 360 sometime soon to connect to this receiver also. Pang movies/gaming lang talaga habol ko para magamit yun 5.1 surround sound.
Thanks!!!
entry level hdmi video pass throughs based receivers with optical and coax audio digital inputs is what you need. i think either a denon 1610 or onkyo 507. yamaha willhave one too but i forgot the model number.
Thanks for quick reply sir. By the way, my Philips SP120 5.1 has a powered active subwoofer (satellites are connected to the sub which has 5.1 channel RCA analog inputs w/c is then connected to my dvd player).
Meron bang RCA analog output yun denon and onkyo? Nakita ko lang kse yun meron (+) and (-) jacks sa likod ng mga receivers same as those output on the subwoofer. If ever pwede ko sasak ba directly yun mga satellites sa receiver? 4ohms each yun impedance ng mga satellites according sa manual, 8ohms nman yun subwoofer.
Sorry sobrang noob question ah. Im just beginning my journey on HT setup kse. Thanks again!!
Medyo may kamahalan din pala yun Denon or Onkyo receivers kahit entry level (papaluin ako ni misis nyan!!! ;D).
Another good tweak for an amplifier is changing the power supply rail diodes to ultrafast-soft recovery type. The best I tried so far was the HFA series from International Rectifiers. An HFA08TB60, is rated at 8amps, 600v, which is good enough for small amps. These can be bought at Farnell or RS Components. The best tweak for an amp.If for instance the entire power supply of an Audio Amplifier (having the typical power transformer (EI core), SS rectifiers, and large electrolytic capacitors) will be changed to a light weight Switching type power supplies with the same voltage and current (like those used in the desktop pc), will there be an improvement with the sound quality as it is almost purely regulated, or will be worst?
Another is to get the best powercaps you could with low ESR rating and bypass with polypropylene types of caps. If space is not a problem, double the uf rating.
And at the output stage, which is normally a zobel network for most amps, resistor and capacitor combination, i normally used a 5Watt Kiwame or Riken and Auricap.
Mga Sir,
I would like to ask for you advise. pasensya na at hindi ko masundan yung thread, ang haba na kasi.
I want to ask whats the best and cheapest 5.1 amp/receiver that has both digital and analog capability?
Im planning to buy one soon, Getting my 1st 37 panny or samsung lcd and a ps3. My old speaker set up in the house that i still want to use are: Front- Wharfedale 2090 8 ohms 200 watts, Satellite- Daichi book shelf 4-8 ohms 200 watts. My sub has 5.1 output but im changing it also to a downward firing one, and my center is just an ordinary old sony component speaker which i plan to change also same time with the sub if budget permits
Thank you

Sir iinas...pasensya na napakanoob question nito:
Meron po akong spare na Konzert av-302 w/c is 2channels only na amp. Balak ko po syang gamitan ng subwoofer. Source po ay PC...balak ko po syang gamiting HTPC pang small room only about 9sqm. Paano ko po makokonek yung powered sub kasi wlang subwoofer-out yung av302? Either of the 2 po na subs ang gagamitin ko>>>a-audio sub of anthony or pilyo's sub+amp4.
are there any receivers that is less than 10k with HDMI input? brand new or 2nd hand?
i dont think there are any for brand new ones. for second hand, you may get lucky, but i would be sure if there are it will be ones with hdmi1.2 spec'ed meaning, it can only do hdmi video and cant decode hd audio like tru hd and dts-ma.
and meron na ba ugn mga konzert ng mga hdmi input?
i think the konzerts and the sakuras still does not have hdmi inputs on their amplifier/receiver products.
hello,
just curious, do typical audio amplifiers have remote controls that adjust volume level of the amplifier? since i plan to use one for my lcd tv.
Thanks.
are there any receivers that is less than 10k with HDMI input? brand new or 2nd hand?
and meron na ba ugn mga konzert ng mga hdmi input?
for stereo amplifiers, some may have and some may not. depends on the model. but for surround sound receivers. a remote control is typical and part of the package that you buy.
if you are on a limited budget (like me :'() you can still enjoy great sounds with an old dd/dts a/v receiver via coaxial/optical inputs. dont fret too much on the hdmi input, it's more of a convenince lang, unless you have a bluray player (for the hd audio).
Agree ako jan.
I'm thinking about buying a Panny BD player, but even if I do get a BD player, I still won't upgrade my receiver just for the HD audio. OK na sa akin ang regular Dolby/DTS via optical.
Pero kung magkakaroon ng mid-priced Yamaha receiver na may internet radio, baka makumbinse na rin akong mag-upgrade sa HDMI receiver. As of now, medyo mahal pa ang receivers na may internet radio, e.
Paano ang connection non? Puwede kaya ang USB wireless? Kung LAN, puwede siguro ang wireless gaming adapter, medyo mahal lang.
Mga Sir Question lang po, may pagkakaiba ba ng PERFORMANCE ang AVR na 110V sa 220 volts?
kasi pansin ko lang sa mga nagttrade madalas inaayawan ang 110 volts ang reason po ba nito dahil sa ayaw nilang gumastos ng regulator para magamit sa pinas o dahil mahina ang performance ng 110 volts na AVR?
Appreciate you reply mga sirs :)
what is the cheapest DD-HD and DTS-HD capable receiver?Super late answer, but since I'm also looking around, I've found the following:
Super late answer, but since I'm also looking around, I've found the following:
- Onkyo TX-SR507
- Denon AVR 1610
- Yamaha RX-V663 (or is it 633? Sorry can't remember)
All of the above are selling for slightly under P21K for cash purchase.
You mean integrated stereo amps? The relatively older ones have motorized volume controls that can be remotely controlled. I used to play with one a few years back. It nice to see their illuminated pointer on the knob rotate from a distance. ;DSaw this on a Pioneer mini-hifi component system about 20 years ago, at my cousin's house in Cebu. It was so cool. The big volume knob actually turned as you adjusted the volume using the remote. :) When I finally got to buy my own system, the volume knob did not do the same thing and I never saw that cool feature again anywhere else :(
if its 663 and under 21K, grab it for two reasons,Sir Onkyo, I'm pretty sure it started with a "6" :) I'll try to look for it again...
1. WalA na nyan sa market even in the US
2. Price of this is around 35K brand new
Hindi kaya 363 yan sir?
mga master,I also have an HT-Z220 and am in the process of upgrading. So far I have bought a 5.1 speaker system from diy_master (the awesome Anthony of A-Audio). I will first try to connect these speakers to my HT-Z220 receiver/DVD player and see if I am satisfied with the result.
patulong nmn po...i want to upgrade my set up..kso i dont know where to start....currently i have a sammy htz220 (HTIB). pde b bli new speaker then palitan ung sammy speaker or receiver muna....my budget is around 20k..khit paunti unti sna muna. our room size is around 5m x 6m...thanks in advance...
what is the differences between stereo receivers and integrated amplifiers. tia
stereo reciever vs intergrated amplifiers alin sa dalawa magandang tumonog
1. a friend of mine is selling an Onkyo HTs5100B for 35K, is this expensive or should I buy separately?
2. Also, If I buy a Receiver instead, whats the best brand/model at 18-23K level with HDMI na? pre loved is ok with me, sabi kasi invest daw sa receivers kaya lang yung nakikita ko puro mga 40k up.. ang mahal,,
3. last, the speakers ba should all be the same brand when you set up your HT, or mix brands are ok?.. any suggestion on a good set up..
35k can get you started with seperates.
I would say invest in the speakers as they have more to do with the sound than receivers. Anyway, I think 18-23k can get you decent receivers from well known brands here like Yamaha, Denon, Onkyo etc.
Ideally, they should be same brand and model. Start with the fronts. I suggest bookshelfs sicne you can put these in the rear in case you get floorstanders in the future.
I'd rather buy an entry level receiver and connect my PC digitally. Some sound cards doesn't have a good DAC. Hence, a not so good SQ. Whereas a most receivers nowadays have very descent DAC for HT. Plus you get the benefit of simplicity in your system, less clutter and proper integration (assuming that you work w/in the parameters of the AV/R). There are also entry level AV/Rs that can accommodate external amplification for your speakers if in case mabitin ka sa amplification ng AV/R.
Just my dos centavos. ;)

Hello everyone,
Newbie here, I do not know if this would be the right thread to ask, but here it goes. I currently have a Marantz PM 72 and an Onkyo Integra A817XD. Both are non-functioning as of the moment because
The Marantz gave way to "too much volume" .. umusok!
The Onkyo, which I was using very carefully (complete with 100VAC transformer) did'nt turn on this morning .. no power, no click, nothing. I opened in up, checked if it was accidentally plugged into 220V, but I did'nt smell anything burnt. I labeled the plug.
Hence my query. Where can I have my amps checked and serviced? I live in Cavite, and work in Makati. I would prefer a shop that is highly recommended in fixing old school amps. If its around Makati, that would be much better.
Please help. :'( Many thanks in advance.
Kung Makati, Rene Rivo is your best bet. He also restores vintage amp to pristine condition.

i'm looking for a budget-friendly (i.e. cheap!) av reciever to be used for a very small room. it should be able to deliver 50 - 80 watts per speaker, has hdmi, optical and coaxial digital inputs and can decode dd and dts. any suggestions on what reciever to get, where to get them and the average price? tia
Don't go for cheap bro, I'll use "affordable" instead ;)
an Onkyo 508 is around 22k, but it would be great if we can have a blackfriday sale here like in the US during thanksgiving,. ;)
Hi Noob here,
my dad has some bose lifestyle v30 speakers. i was wondering if this is compatible with the pioneer vsx 1020k?
what will happen if i have a 5.1 source, a 5.1 receiver, but only have 3 speakers (Left, Right and Sub)?

elo po, bago po ako,
ask ko lang po sa mga expert guru kung magkano ang price ng mga sumusunod jan sa pinas.
1. vsx-820k price in Qatar 1500 QR
2.vsx-920k price in Qatar 2000 QR
at saka made of whatt po ang tatak ng pioneer pag jan ako bibili.
d2 kasi sa qatar made in china, pero yong materials hindi po china balak ko pa lang bumili this weekend.
yong bibilhan ko po distributor mismo ng pioneer d2 sa qatar.
antay ko po ang reply niyo.
salamat ng marami
qwert :)
elo po, bago po ako,Eto po yung cash price last year when i was still looking for a receiver.
ask ko lang po sa mga expert guru kung magkano ang price ng mga sumusunod jan sa pinas.
1. vsx-820k price in Qatar 1500 QR
2.vsx-920k price in Qatar 2000 QR
qwert :)
sir,
ask ko lang po kung reasonable price na ba yong Pioneer VSX-920K sa price na 22K. brand niyo po siya.
need your advice.
regards,
qwert.
when playing CDs i set my AVR to pure direct (vsx520) and only use the stereo mode when playing compressed files thrugh my ipod. ok lang ba to or should i set it always to stereo? trip ko kasi yung pure direct sa CDs para walang coloration yung sound pero i need to use the sound retriever when playing mp3s
[/quote
use the settings that best suit your taste. sabi mo nga my body... my temple... so is my tenga... my timpla... ;)
good day everyone, specially sa mga audio masters. may lumang pioneer receiver kami sira na its a Pioneer 4 Channel Receiver QX 4000, may nagaayos pa ba ng ganung kaluma na item? 70's pa yata yun.thanks in advance.
Mga masters,
Question lang regarding bi-amping of speakers.
Possible ba ito using the preout of AVR?
Would this configuration work?
AVR pre-out ---->>>> Y splitter ----->>>> 2 units monoblock power amp ---->>>> speaker's high and low binding post connection
Thanks :D
Yes, that will work.
Pero walang improvement yan, kasi passive bi-amping lang yan. Magkakaroon lang ng improvement kung active bi-amping ang setup.
Active bi-amping is the true bi-amping setup.
Sa active bi-amping, ang line signal ay dumadaan sa external crossover bago dumating sa amp. Yan ang true bi-amping, kasi yung filter ay nasa line-level signal ("active crossover").
Eto ang tamang connection:
(http://sound.westhost.com/biamp-f1.gif)
Ang problema mo ngayon, paano kang makakatiyak kung tama ba ang design at kung matching ba sa system mo ang external crossover na ikakabit mo? Alam mo ang sensitivity rating ng speaker set, pero ano ang sensitivity ng bawa't isang driver sa loob? Kailangan mo ba ng equipment para masukat ang mga frequencies? Tatanggalin mo ba ang internal crossover ng speaker set para maiwasan ang double filtering?
Sakit lang ng ulo ang mga bi-amping na yan. Ang advice ko, basta ikonekta mo na lang nang normal ang amp sa speaker, hindi ka pa tatanda nang maaga. :D
Ang tendency kasi ng mga manufacturers ay gumawa ng bi-wirable speakers, kasi mas mabenta pag may bi-wiring capability. Ang tendency naman ng consumers, pag nakita nila na may bi-wiring capability ang nabiling speakers, gusto nilang mag bi-wire or bi-amp, para ma-maximize ang gamit ng features. Sayang naman kasi kung may ganoong feature, tapos hindi naman nagagamit.
Bi-Amping: Pleasure or Pain?

Pwede din 1 monobloc per channel. Baka masmaganda. Kesa high & low.
mga masters,
i'm planning to have a set up at home
ok na ba na set up to.
onkyo tx-sr806 at polk audio 1 pair of rti a3 or 1 piece rti 10 (which speaker suits best)
will be placing them on our living room
tia!
That should be ok na. :). Come by the shop to check out the polks and other speakers. You can bring your amp if you want. :)
@courtmaster
pwede na yan. kulang ka lang ng CENTER speaker, POWERED sub at SIDE speaker.
thanks bro unti untiin ko yan.
san pala nakakabili svs sub dito?
ok din ba rti 10?
why dont you try the RTi A9 instead. MLY aka avshop has a pair ready for audition.
@ courtmaster
you won't go wrong namn with polks and onkyo because they are both versatile. they're generally good at HT and audio. but then again, dont limit your choices, there are other good avrs and speakers around. the best way to find out is to listen to them personally with your type of material.good luck.
@ sir nelson de leon..
I'm considering an upgrade of my receiver to onkyo TSR608... yung speakers ko 4ohms resistance lang pero yung sa tsr608 is 6-8ohms... compatible ba siya or meron bang loss of quality? Thanks in advance :)
HI Gurus,
My current set-up >> Floorstanding Phillips (Holland 8 in. cone resurrected by Anthony) speakers complete with center and surround, ONKYO 308, Omni Sub S8, and Samsung 51 D450. I already spruced portion of our living room as dedicated area for the gears. It looks good and sounds nice so far. But I want to improve the sound quality. I've been reading bout pre-amps in this forum and how it can upgrade the SQ.
How would I know the right pre-amp for my set-up? What are the indicators in selecting pre-amp? I'm 50/50 music and movies. What else level-entry gear should I add into my set-up?
Thanks for reading. Will appreciate your advise sirs. :)
I have Kumyoung na, instead of Konzert ampli with KOnzert Speaker
Im thinking of
Using entry level receiver , and maybe 9.1 BS ( entry level n speaker din)
hindi ba masisira kung gagamitin ko to sa Karaoke..
dadami kasi speaker ko if separate pa..
tia
:) good morning masters!
nakakahiya po yung tanong ko but sige for the sake of art .hehe..
possible po ba mag add ng sub sa isang stereo amp na 2 channels only?
my stereo amp is denon dra 685..if pwede..panong configuration?..salamat po..apir!
pwedeng pwede brader!! kung talagang bayo-bayo, kahit 2 powered sub pa!
check mo tong thread na to...
http://www.pinoydvd.com/index.php/topic,142375.msg1458350.html#msg1458350
anong speakers nga pala ang ginamit mo sa 685?
Ask lang po mga sir...
pano po kaya i-configure ang optical going to may pc.
kinabit ko naman ayao sya ma detect sa windows but xbmc andun naman sya
HK155
990FXA Gigabyte
6850 Toxic VC
TIA
Hi mga Master,
Bago lang po me sa HT world... tanong ko lang kung bakit may parang static yung speaker pag on ko ng AVR... nd naman malakas yung static pro pag wala naman naka play, maririnig mo parin sya. na check ko na po lahat ng wires and cables... ok naman po sila. Normal lang po ba yun? need ko po ba mag palit ordinary cable to high end para matanggal yung static?
Thank you in Advance po
Speaker: Bose Acoustimass 5 series II
AVR: Pioneer VSX D902S
Tanggalin mo muna lahat nang sources na connected sa AVR mo itira mo lang speakers ang nakakabit then pakinggan mo kung may static pa din when not playing anything..
Mga master noob question lang. Meron po kasi kaming old Sony speakers yung bookshelf type. Wood yung labas tapos malaki. May black and red wire cya. Connected kasi sa component ito dati mga 1980s pa. Pwede pa ba magamit yun kung bibili ako ng mga receiver gaya ng ONKYO? Ano po recommended? THanks
mga masters super newbie here.. gusto ko sana maexperience yung hd audio and video, the problem is bopol po ako pagdating sa mga wire connection ;D meron ako minana na bose 201 series v from my bro, at gusto ko bumili nung hk 156 avr here in pdvd.. my current set up ngayon is 24 devant led tv with only 1 hdmi port connected to samsung BD player.pag nanonood ako bluray movies bitin yung sound ng tv! ..pag meron na po ba akong hk 156 avr, paano ko ikakabit mga wire ko [hdmi]....... tv hdmi+bd player hdmi+ hk 156 avr hdmi+ bose 201 speakers?
nalilito ako how to achieve the high definition audio video!
turuan nyo naman ako masters..
Yes.
Receiver video output --hdmi cable--> TV
BD Player --hdmi cable (HD audio doesn't pass thru digital coax or optical)--> Reciever source input
Receiver Speaker output ---> Speakers
bale hindi na po didiretso sa tv ko yun bd player,dun ko na sa reciever [hdmi] source input iplug ang bdplayer... then receiver na ang magdadala ng video signal sa tv, via receiver [hdmi] video output?
tama po ba sir nelson? TIA
pahabol question po sa meron avr receiver na hk 156 kung meron ba itong standby pass through. TIA
confirmed HK 156 has no standby pass through feature :(
sayang gwapo pa namang avr ang hk-156.... haaayyy
Ok lang naman ata kung walang standby passthru feature. Baka naman most of the time, when you watch movies, you'll be using your AVR din naman. ;)
Ok lang naman ata kung walang standby passthru feature. Baka naman most of the time, when you watch movies, you'll be using your AVR din naman. ;)
pag tvpatrol news,mas gusto ko pag sa built in tv speakers lang galing audio at standby mode, or off
yung avr..kasi pag laging nakabukas si avr baka mamulubi ako sa kuryente ;D
Standby PassThru is a nice addition...
I play PS3, watch cartoons for my son and watch downloaded series with wifey without turning on the Receiver...
Sa TV ba nakakabit ang cable nyo sir?
Yes. It applies to those situations.
yes direct po sa tv ang coaxial cable from local cable tv provider!
So you don't really need to turn on the AVR to hear the sound maski na wala pass thru ang AVR. ;) The pass thru doesn't apply sa cable connection mo. ;)
another noob question again PDVD masters!
posible po ba ganito set up? from tv hdmi input to bd player hdmi out..from bd player rca audio out to my old receiver rca audio input...lalabas po ba sound to my old receiver 5.1 speakers or hindi because of hdmi..
me inaalok kasi sa akin na murang BD player..HOPING for replies MASTERS!!! :)
di ako master pero pwede pa rin yan. pero hindi yan true surround. check mo baka meron optical o coaxial inputs yung reciever para makalasap ka pa rin ng surround sound
thanks for answering my query sir!
meron po optical input old receiver ko :) my problem is baka di lumabas yung audio sa receiver ko because HDMI is audio and video na di po ba?
baka po wala na audio output capability yung BD player through its optical out dahil naka HDMI na..
di ko rin matesting kasi this bd player is not around :( gggrrrrrrrrr...
meron pa rin yan. not all recievers kasi, case in point, can accept audio through hdmi. there are some newer AVR's that can't accept audio through HDMI even though they have HDMI inputs and they still rely on coax or optical
unfortunately the cheaply offered SAMSUNG BD-D5100 to me has no optical out :( only digital coaxial audio OUT..
bye bye true surround experience for my old AVR :'( :'( :'(
wala bang coax input yung avr mo? di ba standard yun until now?
yep digital din yung coax capable of delivering surround sound. mas mura pa coax cables kesa sa toslink ;)
Ok lang naman ata kung walang standby passthru feature. Baka naman most of the time, when you watch movies, you'll be using your AVR din naman. ;)
Aside from the physical properties, how does the two really differ in performance? Or it is just proprietary based?
what is DAC sir nelson? :-[
heres my cheap receiver back panel.. [pic borrowed from the net]
and believe it or not i never tried to use those pre out L R SURROUND,CENTER, SUB coz im not sure if it would be audible?
[dahil tanging sa speaker line lang ako nagkakabit ng speaker dahil yun lang ang inaakala ko na audible port:-[...nakakahiya man pero yun ang totoo]
my new STUPID question is pag sinaksak ko ba yung RCA speaker wire DIRECTLY from my speakers sa pre out netong receiver L R SURROUND center, sub, eh may lalabas na DIGITAL AUDIO? heres my config... [ TV HDMI INPUT TO BD PLAYER... FROM BD PLAYER AUDIO OPTICAL OUT TO my receiver DIGITAL optical input] can this be possible for tru surround experience?
haay sana wag naman magsawa ang mga masters dito sumagot :-[ :-[ :-[
[/im(http://i1177.photobucket.com/albums/x344/rockyrollin/onkyofr-7gxdv.jpg)g]
@WARMASTER..sorry sir but my cheap receiver has no coax audio input ;D analog audio lang
ayun yung digital audio mo brother, optical input. yun nga lang yung center and surround mo ay pre out which means kailangan mo pa ng separate amps to power those speakers kasi pre out lang siya at hindi lineout.
And unfortunately, wala atang DTS decoding capability.
@rockysta! If your lookin for real surround capability, best if you could purchase na lang a preowned receiver if you have limited budget. The cost of buying external amps to power the surround and center might be the same or mas mahal pa kesa preowned receiver. Plus kung i think limited sa dolby digital ang capability niya.
[/img]
another AMPS :o :o :o hilong talelong na ako sa connection ng isang receiver dagdag pa ulit ng isang amp :'(
meron pa ako isang mumurahing mini i hope [BUT I DOUBT] this could cater the input needs and power for the surround and center pre out....

Digital to Analog Converter.
here's the link po masters...http://uk.harmankardon.com/harman-kardon-product-detail-uk/avr-156-.html (ftp://http://uk.harmankardon.com/harman-kardon-product-detail-uk/avr-156-.html)
Some say that digital coax cable is better in shorter runs. Others say it doesn't matter. The way i understand why better ang digital coax, is because before maging optical signal, may conversion pa na ginagawa from electric digital signal to optical and same with the receiving end. Although the quality of conversion would of surely be dependent on the manufacturer ng device. Unlike sa digital coax, na may minimal loss. Mahabang topic yun. ;D Dati naka-coax ako from source to my DAC. Kaso walang isolator ang DAC ko so nag-optical ako. Didn't hear the difference though.
juice ko po mamatay nalang yata akong di manlang malasap sa aking maralitang hapag ang tru surround?
:D :D :D :D
heto po yung ilang pahina HANGO sa manual ng HK156
Surround Modes
There are different theories as to the best way to present surround sound and to distribute
the individual channel information to the surround-sound system’s speakers. A variety
of algorithms have been developed in an effort to recreate the way we hear sounds in
the real world, resulting in a rich variety of options. Several companies have developed
different surround-sound technologies, all of which can be accurately reproduced by
your AVR:
•• Dolby Laboratories: Dolby TrueHD, Dolby Digital Plus, Dolby Digital, Dolby Digital EX,
Dolby Pro Logic II.
•• DTS: DTS-HD™ High Resolution Audio, DTS-HD Master Audio™, DTS, DTS 96/24™.

AVR 156
Surround Mode Description Incoming Bitstream or Signal
Dolby Digital Provides up to five separate main audio channels and a dedicated low-frequency
effects (LFE) channel.
••Dolby Digital 1/0/.0 or .1, 2/0/.0 or .1, 3/0/.0 or .1,
2/1/.0 or .1, 2/2/.0 or .1, 3/2/.0 or .1
••Dolby Digital EX (played as 5.1)
••Dolby Digital Plus decoded and delivered via coaxial or optical
connection
Dolby Digital Plus An enhanced version of Dolby Digital encoded more efficiently, Dolby Digital Plus
has the capacity for additional discrete channels and for streaming audio from the
Internet, all with enhanced audio quality. Source material may be delivered via an
HDMI connection or decoded to Dolby Digital or PCM and transmitted via coaxial or
optical digital audio.
••Dolby Digital Plus via HDMI connection (source device decodes to
Dolby Digital when a coaxial or optical connection is used)
Dolby TrueHD Dolby TrueHD is an expansion of MLP Lossless™ audio, the same format used on
DVD-Audio discs. Dolby TrueHD adds the features found in Dolby Digital, such as
night mode settings, while delivering fully lossless audio that is a true reproduction
of studio master recordings.
••Blu-ray Disc or HD-DVD encoded with Dolby TrueHD, delivered
via HDMI
DTS-HD DTS-HD is a high-definition audio format that complements the high-definition video
found on Blu-ray Disc and HD-DVD discs. It is transmitted using a DTS core with
high-resolution extensions. Even when only DTS 5.1 surround sound is desired (or
available, if the multizone system is in use), the higher capacity of high-resolution
discs serves up DTS at twice the bit rate used on DVD-Video discs.
••Blu-ray Disc or HD-DVD discs encoded with DTS-HD modes,
delivered via HDMI connection
DTS-HD Master Audio DTS-HD Master Audio technology delivers bit-for-bit reproductions of studio master
recordings for an incredibly accurate performance.
••Blu-ray Disc or HD-DVD discs encoded with DTS-HD Master

waiting for your verdict MASTERS......
basta may true HD at DTS Master audio sure na surround yan at sure na dadaan sa HDMI yang audio nyan. ipon ipon na brother, mag establish ka na ng working budget and audition AVR's na close sa budget mo. goodluck
@warmaster..
@masternelson...
thanks for confirming masters!!! it would be a cheap speakers set up since the room available for this HT set up is only 10x10 feet :D most probably pang mahirap lang na mga speakers ang afford ng lolo nyo ;D ; my only concern for HK156 is the after service and parts availability..ive heard isa lang service center nila sa manila...sabi nila mas marami daw parts and service centers ang yamaha if i consider yamy;s entry level avr..
more power to you MASTERS ;)
May distro naman dito ang HK kaya IMHO, it wouldn't be an issue. Unless you would prefer the sound of Yammy. In which, i would also personally prefer over HK. ;D
And unfortunately, wala atang DTS decoding capability.malabo na mata mo kakanood ng mga nagsasayaw sa patay-sinding ilaw. ;D may dts yung onkyo nya, written at the back panel.

@rocky, kung may pc speakers ka pwede mo kabit sa rear pre-out for the time being. meron ka na low-cost surround system!
meron pa ako isang denon mini, pwede kaya to gamitin to serve as a separate amp to power the pre out SR SL CENTER of the ONKYO?pwede yan for surrounds. toe-in mo na lang front speakers for better imaging, to compensate the absence of center amp/speaker. that setup can match or even outclass an entry level receiver in terms of sq.
Mga Bossing,
May pioneer HTZ111DVD ako HTIB. Huli ko na nalaman na di pala pwedeng mag accept ng digital input eto kasi walang sxa hdmi/coax/optical in..
balak ko sanang palitan ung receiver nya tapos retain ko ung mga speakers and sub nya.
Possible po kaya eto? 4 ohms ang mga speakers po neto.
ano pwede kong ipalit na receiver para sa speakers po?
thanks
like what ive said on the other thread
- baka masira ung receiver na bibilhin mo
lalo na if you play it loud
- technically pwede pero baka masayang lang
so better sell your htib and buy seperates
^banana plugs will fit, and are safer. with bare wires you have to be extra careful against frayed wires touching other terminals.
hi, im newbie with avr.. i currently own a onkyo tx-nr414.. at meron pa lang ako na front(polk tsi300) at rear speakers (polk rtia1)..
ask ko lng, dun sa sp config, para saan ung crossover, ano dapat value nun? at tama ba nilagay ko sa ibang setup..?
"SP Config"
Subwoofer=No
Front=Large
Center=None
Surround=Large
Crossover=100Hz
Double Bass=Off
Bro make all your speakers small at 80hz.. then Sub is yes... for movies
You can also play the settings of making just your Fronts Large then sub is non if you are playing 2 channel music..
hi, im newbie with avr.. i currently own a onkyo tx-nr414.. at meron pa lang ako na front(polk tsi300) at rear speakers (polk rtia1)..ayos na yan habang wala ka pang sub.

Hello mga Bossing!
Tanong lang po!:
Kung ang Receiver ko ay:
Amplifier
• 65 Watts/Channel @ 8 ohms (FTC)
• 100 Watts/Channel @ 6 ohms (IEC)
• 120 Watts/Channel @ 6 ohms (JEITA)
• Optimum Gain Volume Circuitry
• H.C.P.S. (High Current Power Supply) Massive High
Power Transformer
Ibig sabihin po ba ay compatible sya sa 6 ohms and 8 ohms speakers?
At kung ang receiver ko naman ay:
Dynamic Power** (front)
3 ohm 160W
4 ohm 125W
8 ohm 85W
Ibig sabihin ba nito ay di pupuwede ang 6 ohms?
Can somebody explain this?
Pasensya na po, Newbie lang po!
thank sa reply courage,
ONKYO may sale dito sa riyadh, pero SR-307 or SR-414 ata yun, yun lang ang kaya nang budget ko hehe!
If that's your future receiver then dont worry, it can easily drive your 6 ohms speakers..
I ended up with TX-SR313 5.1 Channel.
What's the best (6 ohms?) speaker for a 2.1 setup for this A/V receiver?
(http://img215.imageshack.us/img215/949/dsc0002ta.jpg)
Thanks!
Ang hirap mag hanap nang speakers dito sa riyadh! ito lang ang abot kaya ko na speakers.60w for a bs ??? ang taas nyan.
Luma nang model Yamaha NS-333.... sorry sa setup... headboard kasi, limited ang space!
(http://img824.imageshack.us/img824/9358/onkyotxsr313andyamahans.jpg)
Sabi sa specs nang (onkyo tx-sr313) receiver:
5 ch x 100W @ 6 ohms
Sabi sa specs nang (yamaha ns-333) speakers:
nominal input---60W, max input----150W
Impedance 6 ohms
Tanong ko lang po, di po ba mahihirapan si onkyo?
60w for a bs ??? ang taas nyan.
probably 70w ang binabato ni onkyo mo,clean power.kung tama ang specs ni yamaha 60w kaya pa yan pero wag lang sasagarin
Thanks! meron din murang HT package kaso, passive (tama ba?) yung subwoofer, di ata maganda yun!
Wala kasi masyadong mga hifi stores dito puro jamo pa speakers, meron ilang yamaha (ns-333), gusto ko kasi bookshelf type.
Bro since sabi mo nasa riyadh ka diba?
May bagong bukas diyan na ARCHIMEDIA.....B&W speakers ang ilan sa dala nila...check mo....
good afternoonmura na lang ang pioneer vsx 521.its a reciever and amplifier.
i have a blu-ray player connected sa LCDTV. im planning po sana na dagdagan, pero di ko alam kung amplifier or receiver ang ibibili ko due to limited budget.
Mga sir, sa tingin nyo po kung amplifier ang bilihin ko, anung klaseng amplifier po at anong speakers ang pwede sa kanya. Ganun din po sa receiver..
Thanks in advance.
mura na lang ang pioneer vsx 521.its a reciever and amplifier.
may nakita kse ako kanina lang sa isang mall na konzert amplifier...
my receiver is onkyo tx-sr313 (65 W/Ch. 8 Ohms, 20 Hz–20 kHz, 0.7% THD, 2 Channels Driven, FTC)yup ;)
Kaya ba nito yung polkaudio RTia1 which has 8 ohms Nominal Impedance and a 20-125 watts per channel recommended power amp.?
Thanks ulit!
yup ;)
Ask ko lng po kung pde na ipares d2 yung speaker konzert kss-12 or ks-650v (http://img444.imageshack.us/img444/8161/dsc00313zd.jpg)pede na yan siguro sir, kahit 2 speakers pa per channel.
QUESTION mga sirs :
1. If my AVR has a pre-out, pwede ba kong mag connect dun going to my integrated AMP then speakers?
Will just use it pag mag play ako ng digital audio.
2. Do AVRs have features where I can select between the pre-out and non-pre out?
please pardon my ignorance on such terms and jargons.
Gusto ko sanang set up eh, padaanin ko sa AVR ang digital audio ko, then labas sa pre-out going to my integrated amp.
Then pag movies, sa HT speakers.
3. pwede ba to mga sirs? sorry kung magulo tanong ko.
1. Yes.
2. usually, yun zone 2 preout is always available.
3. You might also want to consider an automatic speaker switcher from Don King Markcrenz.
thanks for the prompt reply Sir Nelson.
I was also thinking of a switcher.
follow up question, if I have two sets of speakers ( 2.0 for audio, 5.1 for HT ), can I connect them at the same time to my AVR ? We'll just select which one to be used.
considering the above metrics are met. 5.1 AVR with pre out ?
thanks
ponky
Kasama sa assumption natin dito yun intagrated amp where the 2.0 speakers are conected tama? If yes, then it's ok.
Mga masters and gurus of Audiophile i have question in my mind and I hope someone can help me
Do i need equalizer to my system?
I have yamaha receiver with marcopilyo amp4v2 and pioneer sub
A bookshelves and planning to buy a 3 way LEFT and Right loudspeaker...
Ano po bang magagawa ng equalizer pag bumili po ako nito?
Mas maganda po ba ang bagong equalizer or yung mga old models?
I play different kind of music but most of the time Hiphop/RNB like dubstep, lilwayne,remix etc.etc. and Alternative/OPM( Linkin park/parokya ni edgar/rivermaya etc etc) sometimes lang po lovesong and oldies song :)...
I hope someone could help me decide if I really need this stuff...;)
Hindi ako audiophile pero let me try to answer your question. If ok naman sa iyo yun sound ng system mo, you don't need an equalizer. Check mo din yan receiver mo baka may EQ na din yan.
Purpose of EQ is for room correction and/or if you want to boost certain frequencies to your liking. Pwedeng gumanda, pwede din hindi depende sa tuning (or preference sound) mo.
Preset equalizer meron sir like Concert Hall, Jazz Club, Disco, Rock Concert yung mga common po sa receiver...
Sabi po kasi ng friend ko mas lalakas daw pag gumamit ako ng equalizer +/-6 dB daw po ang ilalakas and kung bibili naman po ako ang sabi nya yung mga bagong equalizer daw po is matigas ang bass unlike ng mga luma malambot...Mixer na nga lang po sana ibuy ko kaso hindi naman ako mahilig magmix ng music continous playing lang po...
Unless may line driver yan, it's possible na lumakas. Pero hindi ko sure kung kaya ng 6 db. Parang double amp power na yun. Normally speaking, ang electronic EQ dati, and ngayon, dapat walang pinagkaiba ang bass. And, as what an average person percieve as matigas or malambot, for me, is nasa frequency na ilalabas ng track.
Thanks master Nelson... kakareview ko lang din ng EQ sa youtube it can remove unnecessary noise pala so I think i need this stuff...
Last question master nelson if I change my subwoofer to a single 18 inches subwoofer with the same enclosure of marco rather than purchasing another 12 inch sub can i still get the same gapang effect...
I want to save room space kasi sana pag 2 pcs kasi masyado na malaki...hehe
Normally, wala dapat noise ang system mo. Kung may hiss or loud hum (excluding tube system), may problem ang system mo. you need to fix your system, not EQ it. By EQing the hiss (not recorded) of your system, you also sacrifice the details in the recording that the recording company wants you to hear. Example, may hiss sa 10khz due to faulty amp, by lowering the 10khz freq, yun mga decay/extension ng voice, cymbals, ma-le-lessen
Though there are unnecessary noises din na kasama sa recording, why would you want that removed? Masarap madinig yun ubo ng mga musicians from the back etc. ;D Ano yun unnecessary noise na sinasabi mo?
Normally, bigger drivers would require bigger enclosures to maximize it's output and tuning. My 15" sub has more than 8 cubic feet of area. Pwede siguro, i seal mo na lang. But make sure na kaya ng pilyo amp mo ang 18" sealed. And prior to replacing it, kakasya pa ba yun 18" subwoofer (width and/or depth) sa enclosure? Baka naman pwede na ang 15" sa iyo. or add passive radiator sa 15" or 18" sub enclosure. pero, ang alam ko, kasing price na ng sub ang mga passive radiators.
Sa noise sir maybe hindi lang kaya ng bookshelves ko yung music na pinapatugtog ko like Dubstep and Skillrex meron mga noise dun na it looks like it can't handle by the bookshelve speaker distorted and output nya kahit nasa 10 o clock pa lang ang volume knob ng receiver ko and since im still searching for a big Left and Right with a good woofer and tweeter im still searching if equalizer or mixer can add more enhancement to the bass, mid and hi...
haha... parang nakukulangan pa ako sa lakas ng sub ko master nelson im still thinking if i will get another sub of marco or change it to 18 inches like what i see in lab of marcopilyo haha ... magpapalit din po ako ng enclosure syempre galing pa rin po kay sir marco kapag nag 18 inch ako na sub...amp4v2 can handle naman po up to 2kw...
I got your point na. I think you don't need an EQ. You need a bigger and more powerful speaker for that. I think yun noise is, either yun amp or speaker mo ang hirap na. Boosting certain frequencies ng music via EQ will only add stress to your already stressed gears. And the mere fact that nabitin ka sa low frequency ng 12" pilyo sub, music apps pa alng, that means malakas ka talaga magpatugtog. I would suggest sana, mga pro audio speakers kung ganyan ka kalakas magpatugtog kaso from your posts above, maliit lang ang room mo. Though may mga pro audio speakers na stand mounted. Teka, ano ba ang bookshelf speaker mo? Baka naman sobrang liit talaga.
Daichi and JBL po 5 inches woofer lang po ito kaya maliit tlaga hehe and 50W rms 8ohms lang which is not enough for my Yamaha receiver na 65W RMS... Pag nag loudspeaker naman po ako i think receiver should follow because my yamaha receiver has a maximum of 80W RMS only... Good pair na po kaya yung Aaudio charisma na for sale sa speaker marketplace plus my the marco sub or should i get loudspeaker 3 way diy from marcopilyo again...
Ehh hello, paClarify lang... because I am getting mixed answers from googling/binging about the "SW+" setting on my receiver on the internet. (yes I use 2 search engines :D)
Does the setting "SW+" mean that mapupunta lahat ng Bass sa subwoofer regardles of your speaker size settings?
OR
It means pagnaka Large ang setting mo sa front speakers, mapupunta rin ang Bass sa both subwoofer and sa Front Speakers?
Thanks mga master.
If you set your Fronts to Large and enable the sub at the same time. All low frequency will be directed to both your Speaker and Sub..
Ay sorry, bale sa settings kasi merong SW na settings with Normal or SW+ ang option
Di ko alam difference. :)
ok thanks ulit.
I think yung SW+ is if you want to use your Sub even with speakers set to Large...
Normally kasi sa AVR when you set your speakers to Large, walang pupuntang LFE sa sub.. by enabling the SW+ gagana pa din sub mo even with Large settings of speakers. When normal, gagana ang Sub mo only if your speaker setting is set to small..
Ok I just confirmed this last night. Setting the Fronts to Large when listening to Music ok siya even when turning the SubWoofer OFF. :D
Sa Movie ok nakaON ang subwoofer etc.
Ok thanks ulit I understand now ehehehe
Looks like buo na ang HT. Congrats!
mga sir question lang po since am new to this thing (ht stuff)since your using avr.pwede pagsabayin yan.most avr support different ohms combi.
am planning to build a 5.1 setup problem is limited budget lang so plano ko is hinay-hinay lang muna. mix and match nalang siguro muna ng speakers. now my question is about the nominal impedance. i tried reading stuff about these pero medjo nalilito ako eh..hehe! so my plan as of now is ganito:
avr (no particular brand/model yet pero eyeing on yamaha rxv371, rxv471 or rxv473)
diamond 10.5 fs
diamond 10cs
diamond 10 dfs surrounds
sub gx 10? (still looking for other options)
pero since limited budget lang plano muna mag 3.1 setup and will use a spare sony speakers that i have for surrounds. now my problem is wharfes has a nominal impedance of 6ohms and yung surrounds available ko is 16ohms. is it ok to match these speakers? can someone shed light regarding this stuff..yung sobrang simple lang sana..hahaha! salamat po!
well thanks for that! highly appreciated..anong speaker ang 16ohms?
anong speaker ang 16ohms?
konti na lang headset specs na yan :D
question ulit :D
Gaano kaimportante ang Automatic Voltage Regulators and/or UPS sa AVReceiver?
Ano mga advantages? Lately kasi parang nagoAuto Standby itong si Receiver kahit gawin ko na yung mga standard procedures e.g. turn it off, take all the speaker wires off etc.
For some reason, di ko nanaman maGoogle/Bing hehe.
Thanks.

Kelangan mo AVR for that bro. In my area nung wala akong AVR nag auauto standby din receiver ko.. after ikabit ko sa AVR di na ulit nangyari... Yung mga di nakakabit sa AVR ko like modem and router, minsan basta na lang mag rereboot tapos i hear clicking sa AVR ko meaning biglang nag fluctuate kuryente or bumababa sobra voltage...Kita nang ibang members kung gaano kababa kuryente sa amin nung nag EB.. minsan less than 200Vanlalaki ba naman ng gears mo eh.yung kuryente ng subdivision nyo sayo na lang napunta lahat :)
Is there a benefit if I add an EQUALIZER to my NAd 304? Thanks. :)

Thanks. Got me a UPS, but... it went worse. :D
So baka di sa fluctuation ang problem. We'll be sending it to the service center. :)
Help naman! Pano ba babaan yung level ng bass kasi nasa condo kami at ang hirap manuod ng movies kasi nagshashake daw yung mga gamit ng kapitbahay namin. Meron yung sa setting sa onkyo na may + or - dB, yun ba yung aayusin ko?
Baka yun UPS mo is limited sa pag provide ng power supply only. Walang regulation ng voltage. Try mo muna servo motor na avr.
Well meron o walang UPS full stand by mode na nangyari after or bago matapos movie na pinapanuod ko :)
Ayaw na magON sooo I think service center or palitan na hehehe. :-X
You can lower the gain knob at the back of your sub and lower the Sub level at the receiver it self..
My Vintage Akai Integrated Amp says in its back:
A,B (4 to16 ohms)
A+B (8 to16 ohms)
Does this mean that i can only hook up 8-16 ohms speakers if I use A and B at the same time, and if i use either A or B the speakers must not be below 8 ohms? YES
What will happen if i use both A and B with a 6 ohms speaker on B? Thanks ::) IT WILL JUST OPERATE NORMALLY, AS LONG AS YOU DON'T PUSH IT TO THE LIMIT. 6OHMS AT WHAT SENSITIVITY AND WATTS? AND ALSO THE SPECS OF YOUR INT AMP?
Question... Is the yamaha rxv 673 rated at 90 w per channel good enough to power kef r500 floor standers (30 to 150 watts)?
I tried this setup. Ok naman sa pandinig ko, but sabi sa akin ng supplier, di daw labas full potential ng r500 because 90w s peak, not rms.
Sorry for my ignorance, but how does an integrated or power amp work? Is it supposed to replace or complement a reeceiver?
You may want to bring our FS to audition both amps. See if the sound is to your liking.
I demoed an older version of the v473 (from a friend, forgot the model). Sound was clean, powerful but too clinical for my taste (maybe it didnt match my speakers).
Just like you, I was also looking at a 5.1 system but decided on getting a Marantz 5004 because it paired better with my speakers.
Mga sir napansin ko po medyo mabilis mag init yun amp ko. Ano po kaya magandang solusyon dito?blower bro. most of us here do this. intake or out, its up to you ;)
blower bro. most of us here do this. intake or out, its up to you ;)
Blower? You mean fans sir? Safe po ba gamitin yun? Intake at exhaust po parang pc?
A/V Receiver cooler

Low speed setting (at roughly ~60% power)
(http://img.photobucket.com/albums/v70/jojod818/AVR%20Fan%20Project/IMG_0337.jpg)
High speed setting (full power)
(http://img.photobucket.com/albums/v70/jojod818/AVR%20Fan%20Project/IMG_0336.jpg)
Actual tests takes less than 30 seconds to cool down a 45 degree Celcius AVR to room temperature at Low speed setting.
Cheers
i am neutral on the this...there are good solid-state designs as there are bad ones, same with tubes...superb sound, is not dependent on the amps alone, remember that the amps are but a third of the amplifying chain, we have the source, and the speakers to consider!!! so the sum of all three, oh yes, the interconnects too as some would have it!!! these make up for superb sound!!!----nice one for this ... "a good gears need a good piece of screws" same as eating of a nice and tasty foods u can say its a perfect cook when u see all the ingredients...----
i must admit i am a ss guy but only because it is cheaper...and with readily available parts....
you did some serious backreading there bro, that post is almost 10 years old!!!
same question lang mga masters as grohl asked couple of posts back:
2. sa mga new model ng AVR ngayon, meron bang feature na pwede i-bypass yung ibang speakers, like the center and sorrounds para ma-utilize ang fronts and sub speaker during movie watching or when listening to music?
as of now kasi 2.0 lang ang HT set up ko and wala pa akong AVR. so concern ko din po ito kasi wala pa ko plan mag surrounds kasi wala nang space talaga para dun. the most na magagawa ko is fronts, subs (dual maybe kung kaya ng budget) then center siguro? so meron po bang 3.1 or 3.2 set-up? hahahaha!
Ah so wala naman palang kaso yun sir nelson. Thanks!
Ano po ba ang pinaka use ng center speaker? And di naman po ba weird na may fronts, subs and center pero walang surrounds?
Question - I sometimes see amplifiers described as Class A, B, C etc. What does this mean?
Sirs may problems at a HDMI ports ng hk160 ko. Lahat no signal. Magkano pa repair ng ganun at worth it back I repair?
hi all!!
my yamaha receiver's HdMI out port 2 walang output :( i normally watch sa 2nd display and the projector sa 1st display is off
seems yung 2nd hdmi output port and walang display , ma repair pa kaya hdmi out 2nd display ?
o is there an HDMI output i can plug sa 1st display g receiver then split out ? if one exists , any pros and cons if i do this ?
san po kayo nagpaparepair ng yahama avantage nyo ? my Avantage 800 since 2013 pa ata ko nabili matibay talaga !

Sir Jim,
I also have a Yamaha receiver, gumamit na ako dati ng HDMI splitter kasi 3 display kinabit ko, 1 Projector, 1 42 Inches TV and 1 24 Inches LCD para pag nanonood ang son ko ng non stop cartoons.
Bale yung splitter nakakabit sa HDMI 1 nung Yammy, yung PJ sa HDMI 2. Nakakabit sa SPlitter yung 42 Inches and 24 inch LCD.
Ok naman sya, no issue..
idol! thanks ha?
Ayos, extended ulit ang buhay ng Yammy!!

May power sya sir JimYung passive most likely di gagana or magloloko. Read this sa feedback sa mga bumili ng passive splitters sa Lazada.
