AVR watt per channel ratings

[Alexander]

 

Have any of you ever notice that many AVR's will advertise say “100wpc” on a 7 channel receiver but if you were to look at the listed max total rated power consumed you would see something like 560 watts. In this example that really means the most power per channel would only be  the total watts consumed divided by the number of channels. So 80w is the max all channels driven, and that is assuming the receiver itself doesn't use any power to run.

You have to read the fine print with AVR power marketing numbers.  Look at reviews too.  Most of the time, a 9 or 11 channel AVR rated at 110WPC is only for "2 channels driven" at very high distortion.  There's only so much power you can pack into a single chassis that also contains every home theater feature and connection available.

80w max maybe with high distortion.

It is also important if the rating is at 1Khz or 20Hz-20Khz with the latter being far better.
