The LT-84 is an all-in-one two channel infrared (IR) transmitter and radiator (Transmitter/Radiator Combo) packed
into a single mountable enclosure. The LT-84 IR radiator is located behind the IR transparent front panel and
provides line-of-sight coverage of 30,000 ft

(2787 m2) with LR-4200-IR/LR-5200-IR receivers or 7,500 ft
2
(697 m2)
with LR-42/LR-44 receivers. .
The LT-84 is perfect for high-quality audio applications like assistive listening, audio description or language

inputs accept microphone, consumer and line level inputs which are all mixed to the modulated IR transmission.
IR receivers then detect the modulated IR transmission and convert the IR signals back into an audio signal and
presents it to headphones.
For better line of sight coverage or for coverage in larger areas the LT-84 can be combined with up to four (4)
LA-141 Listen IR Expansion Radiators. The LA-141s are connected in a daisy chain fashion to the LT-84 via a
24
AWG unschielded CAT-5e cable. A maximum of two (2) LA-141s can be connected to each expansion link output
on the LT-84 with a maximum cable length of 100 ft. (30 m).
