I ordered a Polk SurroundBAR SDA from Crutchfield's Canadian website and it arrived today in good order via Puralator. The setup for the system was easy to say the least. I hooked the RCA interconnects from the back of the SurroundBAR to the RCA output of my Sony Bravia LCD, set the channel ID to match that of the wireless subwoofer, plugged everything in and turned on the power. So far, so good. The system detected my remote so I could adjust the volume of the SurroundBAR. I went into the Sony's menu and turned off the TV speakers. Then I popped in the BluRay edition of Master and Commander to check out some scenes with dynamic sound effects and dialogue. As the unit played the audio for the first scene where HMS Surprise comes under cannon fire, the SurroundBAR suddenly stopped working. I could see the light was green on top and the subwoofer was pumping out the low bass signal, but everything else was gone. I paused the scene, turned the SurroundBAR off, then back on and the sound was restored. That is until a few minutes later when it stopped again. I went into the TV's menu to see if anything was amiss and could detect nothing obvious.... I had adjusted the volume of the television per the Polk instructions and turned up the volume of the SurroundBAR to a reasonable level. Volume adjustment was accomplished using the remote. All connections seem fine and there is no loss of power from what I can detect. Is there anything else I haven't considered? Could this particular SurroundBAR have a switch that protects it at high volumes in order to avoid blowing speakers? I don't think I was blasting it that loud, but with cannon fire you never know.
