Where sophistication meets functionality, the LA-140 Stationary IR Radiator/Emitter by Listen Technologies stands out as a premier solution for infrared assistive listening needs. This sleek and modern device is designed to blend seamlessly into any environment with its compact form and choice of white or grey finishes. Ideal for venues of all sizes, the LA-140 ensures comprehensive coverage with a substantial transmitting area of no less than 10,000 square feet (929 square meters), making it a reliable option for delivering clear, high-quality audio to individuals requiring assistance.
Engineered for versatility, the LA-140 can be easily expanded by horizontally or vertically mounting two units together, effectively doubling the power of your system without compromising on space.

The unit is not only user-friendly but also smartly designed with three indicating LEDs that signal power status, carrier presence, and absence. These LEDs are designed to deactivate after 30 minutes of inactivity, conserving energy when the audio signal from the transmitter is no longer present.
Architectural specifications highlight the LA-140's efficiency, with the radiator being powered through CAT-5 cabling while the RF signal from the transmitter is carried via a 50-ohm coaxial cable. The inclusion of all necessary mounting hardware in the package simplifies the installation process, allowing for quick and easy integration into any IR assistive listening system.
In summary, the Listen LA-140 Stationary IR Radiator/Emitter is a sophisticated, efficient, and versatile choice for those seeking to enhance accessibility and improve the auditory experience in a variety of settings.
