WIR TX90 DC Two-channel Infrared System


The WIR TX90 DC two-channel Infrared transmitter combines modulator and emitter technology into a single operating unit, which reduces operating cost and eliminates precious rack space. This system comes with receivers and a charging bay.

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 single-channel operation. The coverage area can be easily increased by connecting additional TX9 emitters. A wall/ceiling omnidirectional mount is included, and stand kits are available for portable operation.

Available options:
WIR SYS 90 ADV WHT – white emitter
