Product Description
Listen Technologies LA-140 Stationary IR Radiator
Overview
The LA-140 Stationary IR Radiator from Listen Technologies is designed for use with the LT-82 transmitter and allows you expand your assisted listening system's infrared coverage. Each LA-140 covers up to 10,000 ft², and two units can be powered directly from the transmitter. The unit can also be powered from an LA-205 power supply (available separately).
The radiator is easy to install and hardware is included for mounting the unit to a wall, ceiling, desk, mic stand, or tripod. Power is supplied through Cat 5 cabling, with standard coaxial cabling for the RF signal. Two LA-140 units can be mounted together horizontally or vertically, doubling the power of your system without taking up an excessive amount of space. Built-in delay compensation allows you to make adjustments when using multiple LA-140 units together to prevent phasing problems and signal cancellation.
