Just moved into a house wired for whole house audio. Wires come out in family room. I've learned that a speaker selector could be used for that. My question is if I can use my current stereo (Panasonic - SC-HT70), which is designed for surround sound. I think I can use the front L and R outputs to plug into the selector. If so, then I could still use the other surround speakers that aren't plugged into the selector, right? There are volume control knobs in each room with the built in ceiling speakers, so I would just have to turn those off, I guess, when watching a movie.
Does that sound right?
Also, do all volume control knobs have impedance protection or only some?
Thanks!!
