WIR SYS 91V

SoundPlus ®  Two-channel Infrared System

The TX90 two-channel IR transmitter combines modulator and emitter technology into a single operating unit, which reduces operating cost, eliminates the need for rack space and eases set-up. The TX90 transmitter produces a wide-angle infrared signal that concentrates the IR energy efficiently in the listening area. Operating on the 2.3-3.8 MHz bandwidth, the TX90 is less susceptible to radio and lighting interference. Each TX90 transmitter can cover up to 28,000 sq ft (2,600 sq m) in singlechannel operation with WIR RX22-4N receivers. (The coverage area can be easily increased by connecting additional TX9 emitters). This system features our stylish NEW WIR RX15-2 headset-style, infrared receivers. A wall/ceiling omnidirectional mount is included, and stand kits are available for portable operation.

System includes:

(1) WIR TX90 infrared transmitter

(3) WIR RX15-2 infrared receivers

(1) WIR RX22-4 infrared receiver

(1) NKL 001 neckloop

(1) HED 021 headphone
