LT-82 ListenIR 1-Channel IR Stationary Transmitter

Product Features

• Secure wireless communication – ideal for applications where isolation of the signal is important
• Up to four (4) channels mono, or four (4) channels stereo – no need to sacrifice multiple channels to achieve stereo transmissions (one LT-82 is required for each channel)
• Transmitter can power two (2) radiator/emitters (LA-140) using CAT-5 cabling
• Easy to specify, install and use
• Outstanding performance – ensures crystal clear sound for listeners
• Limited Lifetime Warranty
• True stereo audio (left and right) is transmitted on a single carrier frequency
