I have 3 rooms. each room has a smart TV and speakers in the ceiling. The speakers wire back to a central location. The central location has cat5, coax (cable tv), and the speaker wires. I want to be able to keep one remote in each of the 3 rooms to control the audio and video for that room. Would like to select a video source for the TV and the audio play through the ceiling speakers. Also would like to use same remote and select a different audio source like a streaming channel to play audio in that room. I've heard about Control4 boxes being able to do some of this but figure I need some kind of amplifier centrally located to drive the audio back to each ceiling speaker. Looking for some answers for wiring and hardware to accomplish this home AV automation
