I didn’t power up the amp yet, but I guess I should try it (can’t do it now as landlords live above but will try in the daytime tomorrow). I have RCA’s going from AVR preamp (FL, FR, & C) to the amp plus the trigger cable and associated speaker wires. . So if that works and I run the room correction with the mic then set the levels with my sound meter then I’m all set.
I was hoping to be able to turn off the amps in the Denon for at least the front channels to free up some power for the others
