The Digital IR 25 W Radiator from Listen Technologies converts the digital, modulated signal from a transmitter into IR light. The unit is powered locally and has a coverage area up to 14,000 ft² with four mono standard quality channels (one carrier). Multiple radiators can be used for coverage of larger spaces and each radiator features independent delay compensation to adjust for cable length differences. When more channels and/or a higher channel quality and/or stereo signals are used, the coverage area of each radiator is reduced.

The radiator can broadcast up to 32 channels of mono audio, operates noise-free, indicates its status by the LED lights on the front of the unit, and employs Automatic Gain Control (AGC) to ensure maximum transmission efficiency. The radiator goes automatically into standby mode when the transmitter is switched off to extend the operating life of the LEDs. The radiator can be either ceiling-mounted, wall-mounted, or stand-mounted, and up to 30 digital radiators can be daisy-chained to reach up to 2,950 feet.
