3. GENERAl dESCRIPTION
The Infrared Wireless Microphone System using this IR-802T 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-802T is a 2-channel Infrared Wireless Tuner employing a fixed frequency system with 3 AUX inputs.
It is combined with an infrared wireless microphone and an infrared wireless speaker 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.
4. fEATURES
• Connected to the IR-820SP Infrared wireless speaker (with a built-in infrared receiver) using a single Category
5 straight through cable fitted with an RJ-45 connector, the IR-802T receives infrared signals and sends
mixed audio signals through the cable.
• 3 AUX inputs for PC, TV/DVD, and MP3 audio player.
• The IR-802T’s output can be muted by telephone paging input signals.
• Equalizer control knobs for low-, middle-, and high-frequency outputs.
• Mixing output terminal for the ALD (Assistive Listening Device).
• Operated on 24 V DC using the supplied AC adapter (UL/cUL approved product).
• Frequency response optimized to reduce occurrence of acoustic feedback in a classroom whose typical size
is about 10 m x 10 m (30 ft x 30 ft).
5. HANdlING PRECAUTIONS
• The supplied power supply cord is designed for exclusive use with the IR-802T. Never use it with other
equipment.
• Install the IR-802T as far as possible from fluorescent lights, digital equipment, PCs and other devices that
generate high-frequency noise.
• The Infrared Wireless Microphone System prevents transmitted contents from being revealed to people
outside walls or other shields. However, since transmissions may be eavesdropped by malicious third parties,
it is strongly suggested that the user take responsibility for carrying out measures to prevent eavesdropping.
TOA assumes no responsibility for any damages that may be sustained without taking appropriate protective
measures against eavesdropping.
• When cleaning, be sure to first switch off the tuner’s power, then wipe with a dry cloth. If the tuner is extremely
dirty, use a cloth moistened in a neutral detergent. Do not use benzene, thinner, alcohol and chemically-
processed towels, as they can cause damage to the tuner’s components and parts.
