Yamaha RX-V2500 real watts???

[kirbyevie]

Hi guys,... I just bought a new RX-V2500 and I love it's performance (enough for my ears). I just want to know it's actual power, I mean the RMS continuous watts. It states that the receiver is at 130 watts X 7 rms. is it really 130 watts? I'm getting confused here and a friend of mine told me that it's only 50 watts max!! I want to know the real (actual) power of my receiver before it fry my back surround/presence speakers. I'm using JBL E10 for the presence speaker, E100 for main, E30 for L & R surround, E10 for L & R back surround, EC35 center and E250P for sub.
Thank you in advance... GOD bless.

There are a number of standards for rating the power of amps and receivers. The full bandwidth (20Hz - 20 kHz) FTC rating is the 130 watts x 7 listed in the specs. That means that each channel is capable of 130 watts; it does not say that it can maintain that power when every channel is driven at the same time, unless the specs specifically state that fact.

The top-tier receiver manufacturers tend to rate the power of their receivers into 2 channels, which in the case of the Yamaha means that when 2 channels are driven simultaneously, each can output 130 watts. When all channels are driven simultaneously (a very rare case), the power available to each channel will be lower than 130 watts - that is where claims that the receiver is only capable of 50 wpc come from. So, 130 wpc is true when only 2 channels are driven at the same time and 50 wpc could also be true when all channels are driven at the same time. [Note that to be fair both 2 channel and all channel ratings must be derived using the exact same test criteria - otherwise you would be comparing apples to oranges.]

That receiver has enough power to drive relatively efficient speakers to ear bleeding levels in all but the largest of rooms.

See the All Channels Driven Fallacy thread for a lot more info...

Any single channel, of that receiver, at any given time, is capable of delivering a FULL 130+ watts as listed. This does not mean that it delivers it when you have the volume at 10% though.

When the volume is CRANKED - way up there - that is when the receiver will be pushing the maximum wattage. Since this may rarely, or never, be the case, you likely may never see that much power flowing into your speakers ever.

But, in real world situations, the receiver is 100% capable of it. In LAB conditions, where all 7 channels may be driven at once, it is not capable of it. But, you don't live in a lab, and the real world may drive a rear surround speaker or a center channel at full levels individually.

My advice?

Get bigger & better speakers. TIME FOR AN UPGRADE!

This is such a fun hobby.

Oh, and after the new speakers - get an outboard amp - you'll need more power.

I think the local review gave the amp between 60 and 70 watts with all driven (which pretty much never happens.) Anyway, the amp will satisfy most speakers, although you will definitely want external amplification for your new speakers. Welcome to the club...there's always a bigger fish.

Technically, wattage only means volume, although others say it improves sound quality...but we won't get into that here. It may be worth searching the forums for, however.

Are you kidding BMX? Hopefully, lol. Otherwise.....

What's wrong with his current speakers? Have you heard them? How do you know what he likes in the way of speaker sound?

Isn't this Audioholics? It is ALWAYS time for bigger/better speakers, bigger amps, and more power!

Yes, of course it's a joking - that's why it is surrounded with not one, but TWO smiley faces.

This was taken from Wikipedia:

In the field of audio, mean power is often (misleadingly) referred to as RMS power. This is probably because it can be derived from the RMS voltage or RMS current. Furthermore, because RMS implies some form of averaging, expressions such as "peak RMS power", sometimes used in advertisements for audio amplifiers, are meaningless.
