I got a Denon AVR 2805 a few days back and have a strange problem. The receiver switches off automatically at some times while playing movies. It seems to happen mostly during high pitch and treble music, like in action sequences. (Eg. "the showdown at the house of blue leaves" scene from Kill Bill 1 - great scene by the way). Has anyone faced this before? Am I just doing soething wrong with the way I have set up the receiver? I would appreciate some help.
