I am integrating a moip system across an entire house. Works well 20 receivers / 10 receivers, no issue on that system. Three of the displays are in a bonus room, the displays are all lined up horizontally on the wall Left | Center | Right. Whats the best way to control them on C4? I want to easily swap sources and audio between displays. 1 5.1 channel amplifier in the rack where the transmitters are located.
