Tanong ko lang po kung kaya nito ang 4 na 15" na speakers? Mas malakas po ang rating nito sa 735 na model, sabi ng tindero sa raon kaya raw ng 735 ang 4 na 15". Nag search ako sa site ng sakura at nakita ko na mas malakas po ang model na 730 tapos 5.1 pa. Pwedi rin bang gamitin dito sa av730 ang apat kong speakers maganda rin ba ang tunog kahit hindi ko gagamitin yung center and surround? Paki enlighten naman po ako about sa 5.1 at sa regular stereo type na amp.
Sakura AV-730
Digital Karaoke Mixing Amplifier
Description: 5.1 Channel USB/SD Port
Specifications:
* 2 x 750 watts output (8 ohms)
* 2 x 1350 watts output (4 ohms)
* 5.1 Channel
* USB / SD Port
* Music, Mic Volume Independently Control
* Digital Echo Delay
* 3 Microphone Input
* Built-in 4" Fan
Additional question, nabasa kopo sa isang topic dito na ang konzert 502 na 5.1 din ay pweding lagyan ng powered sub woofer, pwedi rin ba ito sa av730? Hindi naba ito nangangailangan ng additional na equipment kung gusto kong mag add ng subwoofer like crossover?
Pacencya napo baguhan lang. ;D
-
gaano siya kabigat?
-
Hindi kopa po nakita ng personal yung av730 kaya nagconsult ako dito. Yung 735 palang nakita ko. Yung mabigat naman yung 735. Paki sagot naman po yung mga katanungan ko sa taas.
-
as to the sakura with 5.1 channels, pwede lagyan ng sub, i tried mine but with the bass of the amp di na kailangan pang mag sub -- just hook speakers with big woofers. ;)
-

Powered sub po ba? Malakas naba kahit yung standard left and right lang ang gagamitin at hindi yung pang center at surround?
-
That .1 is not powered so hook up a powered sub if you want. yung left and right na channels sa akin OK na ang bass. ;)
-
gagamit papo ng crossover? How much po ang crossover?
-
hindi na..
-
Direct connection nalang po sa powered subwoofer. Salamat sa reply.
-
Hello uli... Ask kolang ulit kung ok lang na ipagsama ang pair of 8 ohms at pair of 4 ohms na speakers?
-
post naman rear panel pictures.
TIA.
-
* 2 x 750 watts output (8 ohms)
* 2 x 1350 watts output (4 ohms)
i find this incredible.....reason i asked for the weight, it is one measure of how powerful the amp is....a look at the inside and we will know for sure....

@Tony
Bought one today. Post ko pictures later.

Dissapointed lang ako sa mic output, not so clear and warm compared to my previous Pro Linear Amp with Shure SM58 microphone. Tsaka bad trip walang knob yung controls hirap mag timpla, need to use flat screw driver pa (provided).
May possible modifications pa ba pwede gawin sa Mic Output nito?
-
how much mo po nabili sir? how's the sound?
-
@jlester87
P4,500 bili ko. ok naman ang sound but yung mic output di ko gusto kahit anong timpla ko di maganda, though eto yung new release model ng Sakura.
Kaya bili na lang ako ng Behringer mic mixer muna.
-
this amp is a step up from the 502's, let us do some math:
45-0-45 on the secondary of the output traffo means that your unloaded rails are +/-63 volts,
assuming you can get a peak- to-peak output of 120 volts, peak of 60volts and rms at 42 volts, then with an 8ohm load, you can get 220 watts sine wave power. notice that the power transformer is only rated at 400va so that actual power may be lower than our computed power.
notice also that the heatsinks are not so big, so go easy on the volume controls..... ;D
in real world operation, music power demands from the power traffo will be much lower than sine wave power, so that the power traffo size is somewhat justified....
and at 4.5k pesos you have a winner...this is a better buy than the sakura av200...

Do you think overkill tong amp sa speaker kong Wharfedale KH1200? Volume level is set on the 1/8 turn lang, sobrang lakas pag nilagay ko sa 1/4 turn. And I noticed that the fan runs faster pag pataas yung level ng volume.
Specs:
Bass 1 x 12" (300mm)
Mid 2 x 6.5" (170mm)
Tweeter 2 x 1" (25mm)
Recommended Amplifier 100 - 200W
Nominal Impedence 4 - 8 ohm
Sensitivity 1W@1M 90dB
Freq. Range 45Hz - 20kHz
Crossover Freq. 800Hz, 5.5kHz
Size with spikes N/A
Size (HxWxD) 356 x 554 x 288mm
Weight 16.6kg
Finishes/Colour Dark Grey
Downside lang talaga yung mic output.
-
^no such thing as overkill when it comes to amps, specially ss amps.....
volume levels does not equal power level....your amps has too much gain that is why you get such levels with just a small turn of the volume control, it does not mean power....
-
@tony
Mas ok kaya if I replaced the amp with jojo's Baby "G"? Since I'll be using mic mixer.
BTW. Just came back from Deeco dito sa Cavite branch. wala silang mic mixer.

sir paki check nlng ung likod ng av730 kung ilan ang ampere ng fuse para macalculate ko kung ilang rms yang av730..pero i think nsa 135watts rms yan..
-
sir paki check nlng ung likod ng av730 kung ilan ang ampere ng fuse para macalculate ko kung ilang rms yang av730..pero i think nsa 135watts rms yan..
more often than not, the power consumption written at the back is the total watt consumption rating of the unit, this includes all other appliances that might be plugged into it.....
not an indication of output power rating.....
power rating of any amps is determined by its power supply......
-
sir paki check nlng ung likod ng av730 kung ilan ang ampere ng fuse para macalculate ko kung ilang rms yang av730..pero i think nsa 135watts rms yan..
the power computations were extensively and correctly discussed by tonyt in his previous post.
-
nakita natin na ang toroidal transformer nya is ac output is 45volts kung ang fuse nya is 6 ampere 45volts x 6 ampere of the fuse = 270 pero dahil sa heat..ang heat ang pangunahing kalaban ng power nababawasan eto ng 50% so divide it into 2 so ang lalabas is 135 or less depending on the heat produced (power loss) kaya sya may heatsink para maless ang power loss and i think that is the true rms of the av730,,kaya tinatanong ko kung ilang amperes ang fuse sa likod ng amp para macompute ung rms nya im just assuming na 6 amperes ang fuse nya sa likod,,second na nkasulat na ac output na 14volts kung ang fuse nya is 6amperes then we calculate 14volts x 6amperes = 84 - 50% heat (power loss) = 42
and some of us tintignan kung gano kabigat ang amp para malaman kung malakas ang amp the more mas mabigat mas malaki ang transformer sa loob its because mas mabigat ang transformer,more power it will produce..

^the fuse is there to prevent fires, it has nothing to do with power ratings of the amp.....
i do not know where you get your ideas, but i say you have them wrong.....
have a read here so you will know better: http://sound.westhost.com/amp-basics.htm
and here: http://www.rocketroberts.com/techart/amp.htm
-
but sir u know the fundamentals of electronics that power,voltage,current and resistance are related from each other..ung sa fuse bakit ba napuputol ang thin metal filament sa loob??its because of over current flowing from the filament kaya sya napuputol at hndi sa voltage..ang fuse ang finifilter nya is current not voltage..remember current is related sa amplification sir pero mostly satin ang purpose tlga ng fuse is for safety purposes pero if u analyze the circuitry the current that flowing from the circuit is equal or lower than the value of the fuse kc kpg sumobra sympre putok ang fuse so ang current na pumapasok sa fuse muna dumadaan so un ung equal or less than the value of the fuse ampere...na related ung calculations ko eto po ang calculator para malaman nyo po na related ang sinasabi ko..http://www.sengpielaudio.com/calculator-ohm.htm (http://www.sengpielaudio.com/calculator-ohm.htm)and para malaman nyo po kung ano ibig kong sabhn bakit tinatanong ko kung ano value ng fuse ng av730
-
^and you still have no clue..... 8)
btw, the transformer is a 45-0-45 traffo, 90volts secondary....
-
sir paki search nlng po ang watts law (power is equal to voltage times current)(P=V*I)and ano ang relationship ng power,voltage and current..sa fuse plang po makikita mo na kagad kung ilang current value ang dadaan sa circuitry ng amp equal or less than lang po kc kpg more than sympre putok ang fuse,,kita nman po sa toroidal transformer ac output kung ilan po ang kaya nyang ibuga na voltage sa circuitry
-
^masyadong basic yang theory mo at walang kinalaman sa power output ng SAKURA 733
to test the power output of any amp you need a dummy load, a signal generator, an oscilloscope or a distortion analyser.....
the maximum unclipped voltage developed across your dummy load tells you the power.......
for the last time, i say the fuse has nothing to do with amplifier power output...... kuha mo? ;D ;D

so then how will you get the power output without calculating the current value??where will you get the current value??
Electrical engineers often need to know the power, P, dissipated by an electrical resistance, R. It is easy to do the calculation when there is a constant current, I, through the resistance. For a load of R ohms, power is defined simply as:
However, if the current is a time-varying function, I(t), this formula must be extended to reflect the fact that the current (and thus the instantaneous power) is varying over time. If the function is periodic (such as household AC power), it is nonetheless still meaningful to talk about the average power dissipated over time, which we calculate by taking the simple average of the power at each instant in the waveform or, equivalently, the squared current. That is,
(where denotes the mean of a function)
(as R does not vary over time, it can be factored out)
(by definition of RMS)
So, the RMS value, IRMS, of the function I(t) is the constant signal that yields the same power dissipation as the time-averaged power dissipation of the current I(t).
We can also show by the same method that for a time-varying voltage, V(t), with RMS value VRMS,
This equation can be used for any periodic waveform, such as a sinusoidal or sawtooth waveform, allowing us to calculate the mean power delivered into a specified load.
By taking the square root of both these equations and multiplying them together, we get the equation
-
so then how will you get the power output without calculating the current value??where will you get the current value??
who says we need current to calculate power? if you have the voltage and the resistance, then you can compute for the missing parameter, this is OHM's Law....
power = E^2/R
my leach amp ouputs 45volts ac into 8 ohms, this is 250 watts....
-
is that rms sir?what about your fuse what is the value of your fuse?
-
yes, sine wave power.....
-
what is the value of the fuse??
-
what is the value of the fuse??
which ones? there are 5 fuses in my amp...i use 10amps for ac input....
-
I am taking this debate positively -- sige lang ;)
-
if u are using a 45volt toroidal transformer and used a 10ampere fuse lets compute
45x10=450 less 50% heat (powerloss depending on the heatsink) = 225
80 to 90% accurate
-
let me ask you sir tony is P=E2/R is applicable in car amplifiers??
-
Sorry bago lang ako dito! Baka hindit dito dapat but I need advice.
But I'm trying to ask what's the best deal on a 32 lcd or led flat tv as the prices seem the same. Sabi nila Toshiba, JVC or Panasonic raw.
Maybe somebody can advice.

Hmm, reading on the discussion below, I admit am confused--- are we discussing theoretical or actual ?
Wish a 3rd party technical and in authority step in to resolve the views below so we may resolve below and move forward to hear performance review/features ng Sakura AV-730, which i am most interested in.
-
let me ask you sir tony is P=E2/R is applicable in car amplifiers??
applicable to all amplifiers.....
NO no no no...all amplifier classes has its own efficiency..class AB is not the same with class D..class AB is only 75% and class D is 85%..
who says we need current to calculate power? if you have the voltage and the resistance, then you can compute for the missing parameter, this is OHM's Law....
power = E^2/R
my leach amp ouputs 45volts ac into 8 ohms, this is 250 watts....
but class AB amp is 0nly 75% maximum efficiency. the peak output is 187 watts or 132 watt rms. 250 watts may be the power consumption but not consistent and not the output power.
-
and one thing home amplifiers rms ranges 50 to 120watts..a 250watts rms amplifier u can consider this a PA amplifier
-
if u compute a 12volt car amp at 4 ohms using the P=E2/R

direct answer: 4 watts. now you ask, bakit may car amplifiers na 100, 200 or even 1000 watts? this is your answer:

-
if u compute a 12volt car amp at 4 ohms using the P=E2/R
what will be the result??
car amplifiers converts 12volts to +/-65volts in some models, they use an smps power supply to convert 12 volts dc to a higher voltage rails, so that higher power is possible...
the legendary KP500 pioneer car stereo used the AN214 ic, in this case power output is a mere 5 watts into 8 ohms....
-
and one thing home amplifiers rms ranges 50 to 120watts..a 250watts rms amplifier u can consider this a PA amplifier
really? i used this leach amp in my home system many years ago.....i used a 15inch woofer, 12inch low mid, 8 inch hi-mids and dome tweeter arrays for highs in a passive 4-way cross-over configuration....
the Pioneer Spec2 which is just as powerful is used in home systems and still much coveted till today...

naku sir hndi fit yang speaker mo sa sakura av730 ang need na speaker sa av730 atleast 12inches..
sa sakura av5024 ko dati im using diy 8 inches konzert speakers but nagpalit ako ng db audio 600watts 12 inches speaker..bass tripper ako kaya hndi umubra ang 8 inches sa av5024 ang nangyari nman sa db audio ko nung bagong taon kinabukasan nung bagong taon nagvideoke kame gamit ung sakura amp and ung db audio tapos may naririnig akong thump na basag..un pla ung left speaker ko un pla ung diperensya tapos nung binuksan ko nakita ko biyak ung magnet ng woofer ko..huhu..and napansin ko kc kpg bumabayo ung speaker on a long bass music grabe init parang bagong lutong kanin..hehe
nagtry narin akong maglagay ng 6inches jvc speakers galing sa component tapos nilagay ko sa sakura 5024 hndi tlga ubra kpg bumayo basag ung tunog parang lumilipad ung cone..so watch it..kung matigas ang surround ng bose 301 mo pede nya siguro ihandle pero i doubt it sa kaso ng av730
-
siguro sir nakakakita ka ng mga konzert amps na 502a na kayang idrive ang 12 to 15 inches woofer sa videoke..what more sa sakura av730 na mas powerful pa sa konzert 502a..so be careful..it is based on my experience..hndi naman po tulad ng mga branded yan na may filter ang signal..china amps or generic amp or even mostly diy uses pure amplification hndi katulad ng mga branded na may added features pa sila like dac,dolby built in equalization etc na kayang magcontrol its like having a car with an automatic transmission vs manual transmission

anong pede na sakura for this then? or any brand for that matter. i just want to put my bose in use for music and use them for karaoke sessions d2. AM a green person, i just need enough to drive these speakers, not necessarily too loud, but safe lang that i dont burn my speakers.

hmm, have no clue how to open/pry the cover eh. noob
ok..your speaker is an 8 inches woofer..try this model sakura av-882 and sakura av3022try to audition this sa raon..kung pupunta ka sa raon sir kelangan alam mo na ung bibilhin mo ung brand and model number sir para sila na mismo ang magbibigay ng mababang price without asking them thinking that you know about that item that you are looking for and say this "magkano mo ibibigay skin??" dont say "magkano" coz it will definitely know that u dont know the price of that item (coz lots of wise businessman out there)..thats the point that they will steady the price and not giving you the lowest price possible..

sa sakura av5024 ko dati im using diy 8 inches konzert speakers but nagpalit ako ng db audio 600watts 12 inches speaker..bass tripper ako kaya hndi umubra ang 8 inches sa av5024 ang nangyari nman sa db audio ko nung bagong taon kinabukasan nung bagong taon nagvideoke kame gamit ung sakura amp and ung db audio tapos may naririnig akong thump na basag..un pla ung left speaker ko un pla ung diperensya tapos nung binuksan ko nakita ko biyak ung magnet ng woofer ko..huhu..and napansin ko kc kpg bumabayo ung speaker on a long bass music grabe init parang bagong lutong kanin..hehe
nagtry narin akong maglagay ng 6inches jvc speakers galing sa component tapos nilagay ko sa sakura 5024 hndi tlga ubra kpg bumayo basag ung tunog parang lumilipad ung cone..so watch it..kung matigas ang surround ng bose 301 mo pede nya siguro ihandle pero i doubt it sa kaso ng av730
hindi kaya clipping na yung amp kaya nasira yung speaker mo?
anyway, ok kaya itong av-730 pang subwoofer amp? (i-ooff lang yung treble) kaya kaya nito yung 4ohms 300W sub? o bili nalang ako sa ebay ng 350w BTL tda7293 mono? mura lang eh nasa 1.5k yung kit (wala pang hsf ska traffo)
thanks

sir, newbie po ako need ko po yung advise ng mga dvd member, may sakura AV-730 plano ko lagyan ng 4 subwoofer 12inches na targa(3way/tweeter/midrange/subwoofer) ano/ilan impedance(4 or 8 ohms) ba kailangan ko ikonsider. thanks for comment and your suggestion
-
@baby_wilmar
you need 8 ohms impedance for 4 subwoofer. your amp can handle a load of 4 ohms
-
sir badoy, thanks for advised, kailangan ko nalang iseries yung targa(400watts) na dual voice coil to get 8ohms
-
sir pag may dividing network ba kailangan pa ba ng capacitor sa tweeter and midrange?
-
sir badoy, thanks for advised, kailangan ko nalang iseries yung targa(400watts) na dual voice coil to get 8ohms
DVC na yung targa mo the best option is only two subs na targa na lang. i tried targa subs at maganda din output nya pagdating sa bass driving the 2 coil at 4 ohms. sayang lang pag nag-series ka ng speaker at masyadong mahal. 4 speaker is the same performance with the 2 speaker. naka-design na ung targa for extra power at 2 ohms. i tried that. di sya katulad ng ibang speaker na parang lumalagatok pag pumalo ng todo ang 40Hz na bass at full power.
much better bili ka nalang ng pre-built na dividing network. kung DIY syempre tweeter and midrange need a capacitor in series connection. i cannot give you exact value kasi ako ginagawa ko hinahanap ko yung actual value ng capacitance based sa peak or full power ng amp na hindi sya distorted.

sir ang ibig kong sabihin yung DVC ng isang speaker ang iseseries ko para maging 8ohms, pede ring palang gamitin yung 2 VC(pede ba ang isang Voice coil sa Speaker A ng amplifier output(Left channel) then yung 2nd Voice coil sa speaker B ng amplifier output(left channel) and other set of speaker same sa right channel(A&B) ang worry ko lang baka maging 2ohms/impedance pag hindi ako nag series ng DVC(to avoid problem sa amplifier). thanks sa mga advised sir, highly appreciated

@mhavs, ikaw ba yung mhavski sa electronicslab.ph?
Sir mhavs, djan ka ba? kamustahin ko lang yung unit mo? seller ka ba ng sakura?
-
@baby_wilmar
pede ba ang isang Voice coil sa Speaker A ng amplifier output(Left channel) then yung 2nd Voice coil sa speaker B ng amplifier output(left channel)
yup pwede. the problem is your amp is only 4 ohms. if you do that its too dangerous for your amp kung magkamali ka switching the load will become 2 ohms. that option is good for 8 ohms DVC speaker. {{pero may ibang trick dyan driving 2 4omhs equivalent to 2omhs without damaging your amp. pero wag mo muna intindihin yang trick. baka masira pa amp mo.}}
better reserve mo nalang ang isang voice coil para kung sakali bumigay ang isang coil meroon ka pa... :) kung ang amp mo is tested to drive 4 ohms then use one voice coil. pero kung gusto mo selectable 8 ohms or 4 ohms for just for a single click of switch you can do that by putting a heavy duty switch.

thank you master, maraming maraming salamat marami akong natutunan, may idea na ako how to set up may sound system to protect my amp (by the way nagpalit kc ako ng amplifier from konzert av-301 to sakura av-730) thank you sir marahil marami na kayong natulungan by sharing your knowledge/ideas
-
kung sakali bumigay ang isang coil meroon ka pa...
in a dual voice coil speaker, if one set of coil burns out, it burns out as a short....nasunog na yung insulation....so even if you still have one good voice coil, distorted na rin ang kalalabasan nyan....
cnnect those voice coils as 8 ohms, your amplifier will be happy that you did... ;)

I handed to my mom a used Bose 301 series V. Paired with a NAD 320BEE, ayos na ayos sa rock and pop!!!! The NAD is only 50 watts per channel. :)

@baby_wilmar
if you want selectable 4 & 8 ohms and you're not familiar with it just PM us. they will help you.
-
sir, ok lang ba kung ang set up ko sa sakura AV-730, 2 subwoofer na 12inches 400watts(for A speaker out) at 2 instrumental 10inches 300watts(for B speaker out) o kailangan talaga na same yung watts ng subwoofer at instrumental or kung subwoofer lahat or instrumental lahat. base sa manual ng sakura av-730 need same watts and impedance para hindi madamage yung amp.
-
anong pede na sakura for this then? or any brand for that matter. i just want to put my bose in use for music and use them for karaoke sessions d2. AM a green person, i just need enough to drive these speakers, not necessarily too loud, but safe lang that i dont burn my speakers.
Ayun!, SAKURA AV-733 pang karaoke at nabuhay na yung FT ko from bien_Uy na BOSE Series III :)
Someone got this from raon just this am para sa karaoke session d2 sa office.
Di ko mafford mag libre ng team ko sa labas for my birthday, so bili na lang ako nito, tutal lagi namang karaoke at inom at kain ang celebration d2 sa opis.
Andoks + aling nene + booze + karaoke 99900 songs --- bottomless fun!
- individual mic controls, for 3 mikes tapos may aux plug para sa itouch/iphone
- 2 channels 8 ohms swak sa Bose Series III old but really nice output!

you mean 1 pair of sub and 1 pair of full range or instrumental. a total load of 4 ohms ganun ba. pwede din naman tutunog din naman yan lahat. pero alam mo walang principles or techniques na mag parallel ng deferent specs ng speaker kasi pwedeng mag cancel ang total magnitude ng sound imbes na maging additive. mas maganda nyan bili ka nalang ng maliit na amp para sa instrumental speaker para di mahirap mag mix.
IME di issue ang power ng speaker. any big amp can drive small speaker pero syempre ingat ka sa volume. pag di na kakayanin ng speaker ang amp lumalagatok yung speaker pero malabong masunog o masira agad. syempre much better na match ang amp at speaker. ang issue sa akin ay yung output impedance and always remember that.
-
@sir badoy
Thank you sir, so far concentrate na lang ako sa 1 pair of sub, yung instrumental next time na lang plus 1 amp.

From the sakura.com.ph, I called their office number, and got hold of their presales technical. sabi nya --- Wag na Sakura AV-730 kasi, while may 3 mic, common and controls for 3, unlike AV-733, per mic ang controls(low,mid,high)
I took time to match my BOSE speakers that i got for trade with bien_uy (speakers --- Bose 301 Series III{(this traded item is so awesome)}) it is 8 ohms na speaker with 10w-120w so shopping around, ito lagi binibigay ko info.
I was on the cheap side so i initially got a Mass amplifier from the plexing vendor ( which returned (2x) coz puro tama yung case as color silver, and later cancelled and got this Sakura AV-733 which turns out to be a BLESSING!)

Sir AV777 ba talaga o AV733? ;D
Target ko kasi yung lower model na AV732 sana kaso mas mababa ang wattage though with equalizer. Accurate o precise ba ang mga knobs? Malinis ba tumunog? Mahal kasi yung nasa mga AV shops eh. Tnx ;)

AV733 pala (hehe duling ako :)
ganda ng knobs malinis, at buo, nasa half lang ako, parang buhay na buhay yung bose ko.
i even tried the 30 years ago na technics SB-5 speaker ng dad ko mula sa bodega, aba, ang galing!

sa mga a-audio boys, pwede ko kaya pansamantalang gamitin ang Genesis BS? pang loob lang ng bahay at si misis at baby lang naman muna ang gagamit (hindi muna pang inuman) - kayanin kaya ng Genesis? takot ako masira lab ko yung speaker eh (wala pa pondo pang videoke speakers ni mastar tony!)

if i'm not wrong this was already available in mid 90's. that was 1998 may amp akong na set up sa studio may ganitong features AVR amp sya. hindi masyado sophisticated pero kahit malapit ka sa speaker walang feedback unless na itutok mo ung mic sa speaker.

Some people swear by them, others swear at them. ;D
malaking factor siguro dito ang setup/installation. kahit naman sa ht gears pag may mali sa setup or installation you can't maximize it. tingnan mo dito sa pdvd minsan ang gaganda ng gears pero di namamaximize coz of some setup/install problems or in some (most?) instances, di alam ng owner tamang gagawin. aminin! ;D ;D ;D

not to mention, di alam ang hinahanap. perhaps due to "hawa". OT na pero ito ang katotohanan sa iba o marami. ;) sobrang nag focus sa technical aspect and aesthetics. nalilibang sa kaka tweak and mix n match. iba rin talaga ang pdvd kasi. daming opportunities. daming setups to compare and admire. madaming magagaling kaya maraming natututunan at sa huli maiengganyo kang gumastos. tipong, "uy, ok yung setup nya a, gayahin ko kaya?" or "that's a good idea, try ko nga". without knowing na ang setup nya ay sapat na sa pangangailangan. some tend to forget to enjoy the music/movies. they forgot to settle down.
trend. curiosity. ego.

Sir,
Tanong ko lang sana. Meron bang pre-out/amp-in sa likod itong Sakura AV-733?
Thanks

eto naman ang sa akin hindi sya sakura pro kamuka rin sya meque ang tatak ganun din tumunog kaya ang dalawang 15 na 500 watts na speaker ang maganda ksi kontrolado mo ang low, mid at high me individual setting ang bawat mic tpos sa ibaba yun pinaka over all control pinaglalaruan ko yun delay at repeat na knob ksi nakakaganda rin ng boses hehehe eto pix nya.

bili nga lang dapat ng magandang mic ksi yun kasamang free mic ng midi player eh walang kwenta merong konzert original mic sa s.m 350 lang ganda ng tunog walang feedback.

Nakasubok na ako ng Meque dati, ok ang tunog ng mic input. Mas ok siguro yan dahil may clipping indicator. High pass filter ba yung yellow buttons sa left side? Magkano bili mo dyan sir?

Wow buhay na buhay pala ang ginawa kong topic! 1 year konang gamit ang sakura amp na av730 ginagamit ko ito sa isang pair of plastic acoustic 15" crown speakers at isang pair ng 12" phaser speakers at isang powered konzert subwoofer so far malakas po ito at napakagandang gamitin sa karaoke. I compared it w/ a konzert 502 mas malakas ito ng di hamak pero ang hindi ko nagustuhan ay yung blower na fan kasi pag mic lang ang gamit for PA purpose minsan namamatay ang amp dahil sa init siguro, compared sa konzert pag turn on ng amp na konzert gumagana na agad ang fan pero min lang unlike sa sakura may sensord sya sa sound off sya walang sound na involved. Pero pag music naman wala akong naexperience na namamataysya
