Description
The grey LA-140 Stationary IR Radiator from Listen Technologies uses standard components, allowing for simple and easy installation. It is powered through CAT-5 cabling, and the RF modulated carriers are delivered through standard coaxial cabling. There are included mounting brackets for mounting the radiator to the wall or ceiling, or to a desk, mic stand, or tripod. Power can be supplied through the transmitter or through a separate power supply. Built-in delay compensation prevents signal cancellation and eliminates the need for additional cabling. The Stationary IR Radiator covers up to 10,000 ft�, and features delay compensation, ensuring no drop out in the IR signal.
