Hjertet i Listen Technologies ListenIR-systemet er LT-82 enkanalssenderen. LT-82 kan fungere i enten mono- eller stereomodus, og overfører lydsignalet ditt til og gir likestrøm til en eller flere LA-140 infrarøde radiator-/emitterenheter gjennom en standard CAT-5-kabel. I tillegg kan enheter kombineres for å tilby opptil fire (4) kanaler med mono- eller stereolyd for utvidede applikasjoner.

LT-82-senderen er en ideell infrarød sender for et bredt spekter av assisterende lyttebehov, inkludert teatre, bedehus, språktolkning og mer.
