Hi Gonk...thanks for your reply...I did check the front panel (with a locked digital signal) and there are no red speaker icons visible. There is audio (white noise) coming from the speakers when I try to do a speaker setup\calibration...so I know there are no issues with either the signal to the amp or the amp itself...that is what I find weird. Can't quite get my finger on it...hopefully it is just something I'm missing!
