My Doc wants to do a system for her office,,she has 3 rooms and wants to be able to put sound into each of them ,,A reciever and a Cd Player will do the trick for music and I,m sure I can come up with some Satelite speaks,,( a little help would be good as I don,t know about Minis) what I need is the ability to run three sets of speakers and be able to control the volume on each,,this can,t be something complicated got any ideas,,Thanks
