My husband recently installed speakers in the 2nd half of the basement. He is utilizing Zone 2 through the MX 450. The problem we are having is that every time he uses the remote to turn on tv etc (zone 1) zone 2 turns on also. The speakers in basement come on with loud music. To turn it off, we have to get the remote to the AV receiver and hit off under zone 2. Kind of a pain. I have the same set up upstairs, but use a different URC. This does not turn on Zone 2. It is all controlled with the AV remote. How do I get the MX450 to stop turning on both Zone 1 & 2? Thanks for any help you can give me.
