The ZC21 from Xantech is a device that provides independent infrared remote control to two audio/video systems from two zones. One emitter port is provided for each zone, plus one common port so that components can be controlled from both zones. The ZC21 is a simplified unit, intended for use when only two zones are needed. When more zones are required, use the Xantech models 795-20 and 796-20 multizone controllers and expanders.
