The Infrared (IR) Repeater System consists of three pieces: an IR Target, IR Emitter and a distribution block for distributing control signals to multiple emitters. The IR Target easily installs in the ceiling or wall, and connects with Category 5/5e cable to the IR Emitter. A separate IR Emitter is used for each controlled audio/video component, through the distribution block in the Structured Mediaâ„¢ enclosure.
