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)

Optional Accessory

MB-15B-BK

The IR wireless system shall consist of an integrated IR (Infra-Red) tuner and audio mixer in a 1U height, 1/2 rack metal housing measuring 8.3” (W) x 1.8” (H) x 12.3” (D) and weighing 3.7 lbs. The unit is capable of being rackmounted via an optional rack kit (MB-15B-BK) or wall/deskmount via an option wall-bracket (TBA). The unit shall provide two independent IR channels, each selectable to one of two available IR frequencies in the 3 mHz range (3.10 & 3.35 mHz). Each channel shall have an independent front panel input level control. The unit shall also be equipped with (3) Auxiliary line input channels which will allow connection of various sources. Each will be designated for a particular source. These include (but are not limited to)DVD Player, PC & MP3 Player, each with a corresponding rear panel input connector (1/8” mini-plug, dual RCA & 1/8” mini-plug respectively) and front panel input level adjustment. There shall be a 1/8” mini-plug connection with volume control for use with an ALD (Assisted Listening Device) though this may also be used for recording or remote classroom feed. The rear panel shall be equipped with a 2-wire MUTE IN jack (on removable phoenix connector) allowing priority override via VOX signal from a school-wide paging source. This signal will mute the classroom audio as well as the ALD output. The rear panel shall be equipped with a three-band Equalizer, providing tonal adjustment for the classroom sound. The unit shall have a rear panel RJ-45 jack for connection to the remote powered speaker/IR sensor via CAT5 wiring. The unit shall power from a supplied external 24VDC power adapter and shall consume a max of 40W at rated output (IR-802SP). Security caps for front panel adjustment knobs shall be supplied and may replace the existing knobs to prevent unauthorized tampering. The unit shall be called the TOA IR-802T.
