Listen Technologies LA-141 Overview

The LA-141 ListenIR Expansion Radiator from Listen Technologies is designed to be used with the company's LT-84 ListenIR Transmitter/Radiator Combo. Up to four Expansion Radiators can be daisy chained to each LT-84 system for additional coverage. The LA-141 and the LT-84 combination are compatible with the LR-4200-IR and LR-5200-IR receivers for coverage of up to 30,000 ft², or with the LR-42 and LR-44 receivers in single channel mode for coverage of up to 7,500 ft². A single Cat 5e cable carries both power and signal to the radiator for a simple one-cable connection. Placing additional Expansion Radiators in the same space can increase your coverage area and freedom of movement. The LA-141 includes mounting hardware for mounting to the wall, ceiling, or table.

Use up to four ListenIR Expansion Radiators to expand your coverage area
Provides gap-less coverage in small-to-medium spaces
Easy installation with included mounting hardware
Included single Cat 5e cable for power and audio signal
Power save mode will shut the radiator off when no audio is present for 15 minutes on both channels, to save radiator life
