I am lucky enough to have inherited a B & O BeoSystem 4500 (alas, without the turntable). I also have the full MCL passive x-tra speakers kit, and two extra passive speakers. I began set up over the weekend, and when I tested the connections (from the relay box a blue cable is attached which ends in six bare wires, which I attached to a short cable with pin connectors to the BeoMaster), I was able to control the extra speakers with the transceiver. A red light came on and off when I pressed it.
Well then I fed the blue cable through a hole in the wall to get the speakers in the next room and set up the relay box near the speakers. I reconnected the whole thing, and now the transceiver doesn't work. I CAN get the passive speakers to work when I turn on the BeoMaster in the next room - then both sets of speakers turn on.
I also set up the Beolink 1000, and it works with the BeoMaster, but not with the transceiver.
Only one thing happened - I dropped the relay box while setting it up (on carpeting). Help!
