Hi, I hope I am making sense with my question. I just moved into a house that is totally wired for home theater. There are center, front (l/r), rear (l/r) speakers in the main room, and 2 speakers in the living room, as well as 2 speakers outside in the back and 2 in the kitchen. I have a lot of wires that are marked pretty clearly. I have no HT components at all currently. What do I need to buy to get started using these components that are already in this home? I read a little bit and think I need an av receiver and a speaker switcher? Can I get an idea or a diagram of what I need to do to get going? thanks in advance for all your help!
