The TX90 two channel IR transmitter combines modulator and emitter technology into a single operating unit, which reduces operating cost and eliminates precious rack space. 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.


The WIR RX18 is a two-channel infrared receiver designed for use with a transmitter operating on 2.3 or 2.8 MHz or stereo. This easy-to-operate, stethoscope style receiver is ideal for listening applications where optimal sound quality is essential. The lightweight, one-piece design is comfortable and easy to clean. An on/off control is built into the arms of the unit, saving on battery life. BAT AP07D battery is included.


This multi-unit, drop-in style charger will conveniently charge and store up to 5 Williams Sound WIR RX18's under-the-chin style receivers. It helps keep your products organized and batteries consistently charged.
