Multi-Channel IR Emitter, 2.3/2.8/3.3/3.8 MHz, black housing, red lens

TX9 emitter produces a wide-angle infrared signal that concentrates the IR energy efficiently in the listening area. Operating on the 2.3-3.3 MHz bandwidth, the TX9 is less susceptible to radio and lighting interference. Each TX9 emitter can cover up to 28,000 sq. feet (2,600 sq. meters) in single-channel operation. The coverage area can be easily increased by daisy-chaining additional TX9 emitters. A wall/ceiling omnidirectional mount is included and stand kits are available for portable operation.
