I just moved my 3311 to the bedroom. I bought a 4311 and two more speakers for the living room. I am using the 3311 with a small Klipsch mini-system (HD500) in the bedroom. When I run the setup I get phase warnings on several speakers. I have been connecting and reconnecting for the past two hours. If I reverse the red and the black, the three botched channels (CC, SL, and SR) pass. If I leave them correctly connected (black to black and red to red), they fail with a phase warning. Any help would be greatly appreciated. When I plugged in the 3311 in the bedroom, there was a software update. I ran it, and it completed successfully. I never had any problem in the living room with larger speakers.
