3. GENERAL DESCRIPTION
The Infrared Wireless Microphone System using this IR-820SP is a PA system designed for use in the school
classrooms assuming that their size is about 10 m x 10 m (30 ft x 30 ft).
The IR-820SP is a ceiling-mounted powered speaker with the infrared receiver and offers a wide frequency
range of high-quality sound output. It features a digital amplifier for the amplification section, and a full-range
speaker for the speaker section.
Use of the supplied mounting hardware and optional HY-TB1 Tile Bar Bridge permits it to be versatilely mounted
to match a wide range of applications and installation locations. This speaker is combined with an infrared
wireless microphone and the IR-802T Infrared Wireless Tuner to make up the infrared wireless microphone
system.
The infrared wireless microphone system eliminates problems with interference or eavesdropping, allowing
simultaneous use in adjacent school classrooms.
