Hello, I just closed on a house that is wired for sound. It has 5.1 surround in the living room, 7.1 in the theater, and it has 3 sets of two speakers for music. All of the wires go to one box in the basement. I have done a little research and know that I need to power the speakers, and I need an audio controller that can do 4 zones, if there is such a thing. (two of my music speakers are close together, so we can keep them on the same zone.) So, do I find a audio system that has 4 zones and like 20 channels to power the speakers? or do I get two systems with 10 channels or so, or do I get a system and an amplifier?
