The IR-802 Infrared Wireless Classroom System consists of an IR Integrated Wide-dispersion Ceiling Speaker (IR-820SP) with a built in Infrared Receivers and Amplifier, an IR Wireless Tuner (IR-802T) and hands-free (IR-300M) IR Wireless Microphone, all connected by one CAT-5 cable. This system provides uniform sound throughout the classroom. Cost effective and providing quick installation, this system requires only one wide-dispersion Ceiling Speaker where conventional classroom systems rely on four ceiling speakers. The advantages of using an IR Wireless Classroom system is confidentiality, no longer a need to worry about using up all the available UHF channels, intelligible sound transmission, and the reduction of teacher fatigue during class.
