I have a Beocenter 7700 that I bought new back in 1986 and in the former house I also had it linked via MCL links.I built my current home and had it all wired with B&O wiring.Installed MCL2A's 3 of them for the three sets of extra rooms speakers and links.Problem is that my beocentre 7700 remote will not control the links in the other rooms
