I don't have that specification and I don't have a way to measure it anyhow. 2 channels driven is the published spec and it is a common spec, which is why I used it.
All channels driven simultaneously is not a common occurrence in any mix, so as a specification it's actually less relevant than the 2 channel spec. That's because the 2-channel spec gives you a better idea of what the built-in amps can do under normal conditions, which involves a dynamic allocation of power to the channels that need it.
There's a reason AVRs have "power supply limited" amplification... it's wasteful to put in a power supply that could feed all channel concurrently at full power and likely would create too much heat if someone ran it that way.
I'm not going to get bogged down obsessing over power specs. If someone feels insecure about their AVR delivering what they want, power wise, they should add an amp. Problem solved. Most folks using bass management who have subs in their system will get along fine with the built-in amplification.
It's likely someone else (audioholics maybe) will provide the number you seek anyhow. Anyhow, I'm not going to go after that spec because as I noted, it's not that meaningful and I don't have the means to measure it anyhow nor the motivation to start.
