Listen Technologies LA-140 Stationary IR Radiator, White

Optimize assistive listening and IR-based monitoring with the Listen Technologies LA-140 Stationary IR Radiator. Designed for professional installations, this infrared radiator delivers predictable coverage up to 3,716 m² (40,000 ft²) per unit so every listener or operator receives a clear, interference-resistant signal. Two LA-140 radiators can be mounted together and powered by a single LT-82 transmitter—or by an optional power supply—over standard CAT-5 cabling, simplifying networked installations and reducing rack space. The compact 8" × 5.5" × 2.6" enclosure and multiple mounting options (ceiling, wall, desk, tripod) make the LA-140 ideal for theaters, conference centers, surveillance command centers and other security or monitoring environments that require discreet, dependable audio distribution. Reliability features like delay compensation and automatic diode shutoff maintain uninterrupted performance and lower service demands. Backed by Listen Technologies’ pro-grade design, the LA-140 is a flexible IR emitter for assistive listening and secure audio delivery.
