ONKYO TX-SR600
SPECIFICATIONS:
80watts/ch wit hall channels driven (6)
90 watts/channel in stereo
DYNAMIC POWER TO THE FRONTS:95WATTS




From a posts on audioreviews a few months back, I remember someone bashing my reciever for producing only 30/ch when all the channels were driven.

What confuses me is that amps supposedly output variable amount of power (DUh!). Shouldn't that equate to 0 watts/ch if nothing is inputed... or is that figure the 30watts/ch that figure?


This begs the question can the capacitors on my Onkyo tx-sr600 peak @ 6x80...as in 80watts delivered to ALL channels simulataneously? (such as in a really loud movie scence or music etc)


I know from conducted tests that ~91watts/channel are delivered to the Front two speakers in stereo, but what does that figure mean....Peak? Or are the always at the Specificated 80watts/channel

This doesn't really answer your question, but it might help you out...

It really depends I think. Harmon Kardon is well-known for putting out output numbers that are very conservative, and tests have shown that often these numbers are too low even when all channels are powered.

Various other companies are very liberal with their output numbers, and 3rd party tests show that their numbers are unachievable or only show the peak output.

In conclusion, I guess don't trust the numbers but trust your ears more.

I agree, but I am not referring to the watt/s scheme.


Basically, the amp prolly isn't pusing 80 watts x 6 al lthe time, but can it?

Say a 'sustain' in music......

That Onkyo more than likely can do it. Now, lesser brands probably can't

Appearntly the 70 watt/channel HK's can top out at 140watts according to what someone wrote on here the other day.


If so that's awesome
