Weird problem - Rear output plays out front speakers
I've had a Marantz SR7102 for some time now, the package initially came with bad network card... had to get that fixed. So recently, all of a sudden when surround left/right, back left right need to play, they all go out the front.
It just randomly happened. No setting changed, or anything. I did a factory reset, still no luck. My kids often have the remote (yes I know better), and possibly a setting was changed. However, I thought a factory reset, going through the Audyssey setup would have resolved it.
Any thoughts, or something I should be looking at?
