I just bought the 1804 model and hooked up all of my speakers to it (5.1). When I listen to music it plays through the 2 main speakers plus the sub. But I wanted to know if there was a way to switch back and forth between my rear speakers and my fronts so I can hear the difference as they are 2 different models. I cant seem to find anything in the manual and I have played around with the remote for a while here, yet cant seem to find it. Thanks to anyone who may be able to help.
