I believe if you only have a single rear channel speaker hooked up to my 3808 the Denon will run the system with surround and rear channels into that one speaker, so it should be possible depending on the receiver and its algorithms.

I just checked my manual and it states if no surround speakers are hooked up then you can not use the rear channels, yet I am sure I disconnected them and tried out this 4.1 sceanrio and it worked, could be I didn't set them to NO in the receiver and only disconnected them to check on how the rear center sounded on its own. So it seems that this 4.1 scenario will not work.
