WIR TX90 DC Large area multi-channel infrared transmitter
Energy-efficient WIR TX90 DC emitter -- now featuring a DC power supply. Improved range - up to 30,000 square feet!
Features
The powerful four-channel WIR TX90 DC transmitter combines modulator and emitter technology into a single operating unit, which reduces operating costs, eliminates the need for rack space and eases set-up. The WIR TX90 DC features application pre-set controls for music, voice or hearing assistance applications – no guesswork required for audio configuration. Everything you need for installation is in the box.
The powerful emitter produces a wide-angle infrared signal that concentrates IR energy efficiently in the listening area. Operating on the 2.3-3.8 MHz bandwidth, the emitter is less susceptible to radio and lighting interference. Each emitter can cover up to 30,000 sq. feet (2,787 sq. meters) in single-channel operation. The coverage area can be easily increased by daisy-chaining additional WIR TX9 DC emitters.
