Currently I have my x3700 set to 11 amp mode and I'm powering 5 channels with an external amp and using the Denon to power my 4 height speakers. Soon I'll be adding 2 more channels so 7.2.4 in total and will just be adding the 2 extra channels to the Denon amp (surround backs).
My question is really just about how the amp setting works on the receiver. If I go by the image shown in the settings it looks like I have to run it at 11 channel amp mode for it to accept the external amp over the channels I want externally amped. If I switch between settings like 7 or 5 channel amped the image claims to require me to have the height channels and zone 2 channels externally amped.
Thanks!
