IR-802T

INFRARED WIRELESS TUNER

IR-802T

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 #83x 10 m (30 ft #83x 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.

Designed for use in the school classrooms assuming that their size is about 10 m x 10 m with simultaneous use in adjacent school classrooms
Equalizer control knobs for low-, mid- and high-frequency outputs
Frequency response optimized to reduce acoustic feedback
3 AUX inputs for PC, TV/DVD player and MP3 audio player
Output muting by 25 V speaker line signal from emergency/intercom paging
Mixing output terminal for ALD (Assistive Listening Device)
