General Description

The Listen Technologies LA-141 is an infrared expansion radiator that can be added to the LT-84 ListenIR Transmitter/Radiator Combo for additional coverage of up to 2787 m² with LR-4200-IR/LR-5200-IR receivers or 697 m² with LR-42/LR-44 receivers in single channel mode, when mounted within 30.48 m of cable length from the LT-84. Up to four Expansion Radiators can be daisy chained to an LT-84 system.

A single CAT-5e cable carries both power and signal to the Expansion Radiators making it a true one-cable connection. Placing additional Expansion in the same room increases the overall coverage area and enhances the freedom of movement within the room. The included mounting hardware allows the LA-141 to be easily mounted to the wall, ceiling or table.

Features

Use up to four LA-141 to expand the coverage area
The only product of its kind that provides complete, gap-less coverage in small-to-medium spaces
Easy installation with included mounting hardware and single Cat-5e cable for power and audio signal

Delivery Includes

1 LA-141 Expansion radiator
1 7.6 m CAT-5e cable
1 LA-344 Flexible mounting hardware
1 Quick start guide
