ListenIR Expansion Radiator (For LT-84 Only) The LA-141 ListenIR Expansion Radiator is part of the most advanced, lowest cost IR solution available.The LA-144 can be added to the LT-84 ListenIR Transmitter/Radiator Combo for additional coverage of up to 7,500 ft² (697 m²) per LA-141, when mounted within 100 ft. (30.48 m) of cable length from the LT-84. Up to four (4) Expansion Radiators (LA-141) can be chained to an LT-84 system.A single CAT-5e cable carries both power and signal to the Expansion Radiators (LA-141) making it a true one-cable connection.  Placing additional Expansion Radiators (LA-141) 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.Audio
