I just brought home my new AVR 635 last night and haven't had much time to play with it yet. But when connecting my components I noticed there's no apparent tape monitor loop. I used this with my old receiver to put my external equalizer in, which meant I could use it with any audio source. Is there any way I can use the EQ with multiple sources with the 635? I believe I should be able to do something ridiculously cumbersome with the zone 2 functionality but I'm hoping there's a better answer.
