I had an older model Denon that had a power outlet on the back. The installer had the power for the zone 2 amps plugged into this outlet so that they would go on and off with the receiver. I recently bought a new Denon, AVR-2112CI, so that I could upgrade to HDMI. This version does not have a power outlet. Is there still a way to have my amplifier power on and off automatically with the receiver?
