So how would one hook up an older receiver to work with a newer one? And the main receiver still needs to "process" 11 channels?Technically it's 7.x.4 by the way. 7.4 would be 7 bed layer channels and four subwoofers. Scott would approve, but that's neither here nor there.
The AudioSource AMP-100 is one of the more common ones used.
I run the Onkyo M-5010 in my set up.
Any 2 channel stereo amp will do it...even an older receiver can be used.
