I am new to the forum and have seen quite a bit about this topic but am still confused. All I am trying to accomplish is to play music (either CD or Radio) on Patio Speakers and have the surround speakers inside the house off. I just can't seem to get the multizone feature to do this. I wrote Denon 4 times and got no response. The only advice I received from the salesman was to purchase an additional amp and use the REC out of the Denon.
