As far as I know the Master Control will only work with a Beosystem 5000. For the 7000 I would get a Beolink 7000. For daily operation a Beolink 1000 or 5000 is best, but a Beo4 will work as well, although that's a bit more complicated. I'm not sure if any of the other Master Control Panels (5500 or 6500) will work, but I think they do.
