My Denon 4802 allows me to assign a set of speakers in another zone via the surround 'B' speaker terminals - but I have them tied up in a 7-speaker setup in our family room. If I could wire the surround speakers AND a pair of living room (2nd zone) speakers to a switch box and wire that box to the one set of speaker terminals, I could switch back and forth between the surround 'B' speakers in my family room and the 2nd zone speakers in my living room. I could then adjust the receiver setup whenever I want to pipe music into the living room. A pain to be sure, but the only other solution is to run patch cables from the multi-zone preamp outputs to another receiver or amplifier in the living room (which is probably what I'll wind up doing). Does anybody know if a box that allows you to wire two seperate sets of speakers to one set of speaker terminals and select which set of speakers receives the output signal from the receiver exists?
