Williams AV WIR TX90 DC Large-Area Multi-Channel Infrared Transmitter, Black

Optimize audio access and compliance in large venues with the Williams AV WIR TX90 DC large-area multi-channel infrared transmitter. Designed for theaters, houses of worship, conference centers and monitoring rooms, this Pro Assistive Listening Devices unit combines modulator and emitter technology to cut rack space and lower operating costs while delivering consistent, interference-resistant audio. The WIR TX90 DC covers up to 30,000 sq ft in single-channel mode and supports a frequency response from 80 Hz to 15 kHz, ensuring intelligible speech and full-range program audio. Its 2.3–3.8 MHz modulation bandwidth reduces susceptibility to radio and lighting noise, making it ideal for environments where security, surveillance, and monitoring systems operate alongside assistive listening solutions. Wide-angle infrared radiation concentrates energy where listeners need it most, and coverage is easily expanded by adding WIR TX9 DC emitters. Wall/ceiling mounting is included and portable stand kits are available for temporary or touring setups.
