Yamaha RX-A1060 and WPC

Hi folks,

Yamaha RX-A1060 is rated 120 W per one channel and 110W per two channel. So, for example if I run 7 channel stereo simultaneously what would each channel deliver (guess 30W, 40W ..) ? I can't find that information in Yamaha specs. Rating 110W per 2 channel is confused when receiver is 7.2 type.

Ten years ago, I had a Yamaha RX-V420 it clearly said 65W per channel. Why WPC (watt per channel) is no longer used in nowadays' rating ? Thanks

Because receiver manufacturers are trying to fit everything they can processing wise in a one box solution and the amp is secondary because they are trying to keep all that under a certain price point. It's why I no longer trust receivers and have been forced back to separates. They are trying to be everything to everyone.

Because it was dishonest to consumers. Yes receivers pack a lot into one box. Not that their amps are bad but if you have speakers that present a difficult load to the amp you may not be able to hit the high volumes you had hoped for.

Love my 3060 too btw!

A good estimate is about 70% of the 2ch rating into all channels at once. So about 75 watts, give or take. Watt per channel ratings are useless, unless the manufacturer has actually done an all channels driven test from 20hz-20khz. The 2ch FTC full bandwidth rating is the only one that means anything. A 1khz 1ch driven at 10% THD is useless. Multichannel power is almost always limited by current. 110w into 8ohms is 29.7v, and 3.7A, 7.35A for both channels. Does the receiver list output values into 6ohms and 4ohms or peak power ratings? Those ratings relative to the 8 ohm rating can give you an idea of how good the PSU us at delivering extra current.

Here's an examples of bench test data for a Yamaha and a Denon lower end AVR WPC for 1,2 and all channels:
