Hello BWers, Thought I'd share a note on my MCL setup from the weekend. I have extended my living room 3500 system to the kitchen via MCL cable from speakers 2 on the BM. This runs to the usual Xtra speakers relay unit and is operated by the usual transceiver in the second zone which is the kitchen. Music plays, full remote control, all is good. However, in the main room I found that I have fully independant volume control. I hadn't thought it through completely: my main set-up uses a BV7 as the main audio/visual source. This is connected to the Beosystem 3500 via a ML/MCL converter. So if I start playing a record in the living room - through my Pentas - then I go downstairs to the kitchen and unmute that room, I can adjust the kitchen volume without any interference with what's happening in the living room - and vice versa. Nothing earth shattering here. But it was an unforseen bonus of extending music into the kitchen.
