Topic: 110V-120V AV Receivers

[rhodem24]

Hello mga sir!

Okay lang ba if 110-120V yung AV Receiver ko? Then i'll just use a step down transformer/AVR? Or what would you recommend? Step down transformer or an AVR? Is it safe?

I'm planning to buy an Onkyo TX-NR509 here in pinoyDVD, but the only problem is the voltage. Anong brand ang ma recommend ninyo?


Thanks!

[joko11]

any of them will do the job.but if i were you il get avr with 110 output.

Thanks for your input.

What brand would you recommend po?

[reynold]

Stac kaso mahal, you can go with Yaden, Goldsource, Panther, Omni, etc.. Just get a high-wattage avr, 1500 watts or higher...

[joko11]

any reputable brand is aok.
panther omni or imarflex.pm ricky regarding imarflex.i think he still sell this brand

Like you, it was my first time to own a 110V receiver (Onkyo 809, bought 4 months ago).  I decided to get a 1500W AVR (Stac), and so far, I've never had a problem.  Do take note that since you're plugging it to the 110 outlet of the AVR, you can only use half the total capacity of the AVR.  I'm not an expert on this but the way it was explained to me is this... The total wattage of the equipment plugged to the AVR should not exceed 75% of the AVR capacity (for a 1000W AVR, it's wise not to exceed 750W if you're plugging in the 220V outlet of the AVR or 375W if you're plugging in the 110V outlet).  I hope somebody corrects me if I'm wrong.  So it's really better to get a higher capacity AVR (at least 1500W) since you'll also be plugging your  TV, DVD/BD player, NMT.....

On a side note, Stac is a very nice AVR but the fan is a bit noisy, though you won't hear it anymore once the movie plays.  Also, it consumes more power (20W compared to a similar 1500W akari AVR which consumes 8W....both tested using a power meter).  But you get the peace of mind that your equipment is in good hands.

sorry for the OT, but i think this should be relevant as well...

@R1DVD, can you share some info on the measured power draw of of your 809 in typical movie viewing? (peak and average wattage readings would be nice)

[rhodem24]

Thanks bro!

The Onkyo TX-NR509 has a power consumption of 410W (based on the specs sheet). Is it okay if im going to use a 1000W AVR (with one 110V and three 220V outlets)? 110V for the Receiver, 220V for the Samsung 40" LED, 220V for the Samsung Bluray player and the other 220V for the SkyCable box. Or should I get the 1500W?

[rthirtyfourgtr]

^ if i were in your shoes i'd get the highest wattage i can afford (headroom for future expansion,) stick to brands with good build quality.

Here is the setup.  Onkyo 809 receiver with the following speakers attached (B&W 684 for fronts, B&W HTM62 for center, and Energy Take 5 satellites for surround.  The SVS SB12NSD wouldn't have any effect as it has it's own amp and power source.  With only the Onkyo 809 attached to the watt meter (the BD and PJ attached to another Voltage regulator), I got the following readings:

Onkyo turned on but no sound playing (70W)
Playing Avatar BD in my usual listening volume (70 db) = 80-100W
playing Avatar BD at THX reference volume (82 db) = 85W-160W.

The 160W reading registered at the watt meter during those scenes with explosions, but for those scenes with dialogues only, average is 85W.  By the way, subtract 8W from all these readings because the Akari Voltage regulator that I used consumes 8W.  

Based on the specs sheet, the 809 has power consumption of 710W but I guess it will only consume that much electricity at full volume.  The 160W reading that I got was taken at THX reference volume which is pretty loud na rin.  While watching movies, I rarely find the need to turn volume up to reference level.

The 1000W AVR can probably handle it.  My Sony 40" LED TV consumes only 48W.  The BD player consumes much less.  I'm sure the onkyo 509 won't consume 410W at your usual listening volume.  But I suggest getting a 1500W for future expansion/upgrades

thanks for sharing, at least now i have a rough idea. currently using an 805 rated at 870W on a 1000w transformer, so i guess i should be fine for now

[-lee-]

what could possibly happen if the stepdown transformer is not enough for the receiver? i'm using a 500VA stepdown transormer at the moment to power my denon 1912, rated at 460W based from the specs.. i guess everything's working fine but it doesn't stop me from wondering what if i'm using a higher rated transformer..

Maooverload po yung transformer which would eventually burn its internal windings if used for longer periods of time. To be safe do not use under rated / lower capacity transformers. In industry it is recommended not to exceed 80% of transformer rated capacity

You need to provision 1k step down for the receiver load alone , 460 watts /.7 rounded up to the next available transformer. I went for imarflex 2kva with both 110v and 220v plugs in a black finish, great transformer/regulator

[-lee-]

thanks for your inputs mga sir. may Panther stepdown transformer 1kVA pala dito, eto muna gagamitin ko, buti hindi na ginagamit 

medyo mainit nga yung 500VA pag matagal naka-on yung receiver..

Thank you all for your replies.

I went to True Value this afternoon and I saw a couple of AVRs. Omni, Panther, etc... 1500W costs around 4-5K. Each of them has at least 1 110V and 3 220V.

Is it okay to plug in the subwoofer in the same AVR or not? Separate na lang? I think 350W yung US Audio 512.


FOLLOWUP QUESTION:

120V pala yung Onyko na bibilhin ko, okay lang ba to use it sa 110V na AVR? I can't find any AVRs or Step down transformer that has 120V outlet, 110V lang.

Yes, 110V AVR is ok for the 120V.  I was concerned too about this but after researching on the web, I learned that 110V is ok.  

With regards to the subwoofer being plugged in on the same AVR, I'm curious as well as to the opinion of our experts here.  I was previously advised by someone not to plug it on the same AVR.  But after measuring the total power draw of my setup (receiver, BD Player, SVS-Sb12NSD),  I got a maximum reading of 250W (at THX reference volume, with loud explosions at that) which made me confident that my 1500W AVR can handle the power requirement.  I've been doing this for 4 months already and so far, I've never encountered any problems.  The important thing is you should know the power draw of your setup and you get a higher capacity AVR that can handle the power requirement.  It would be wise to also invest on a watt meter.  Mine is OMNI watt meter which I got from Wilcon Home depot for P995

Thanks... I just have to separate the subwoofer from a different outlet. Just to make sure. Hehehe
