FAQ
Q What is the warranty of Listen transmitters?
A Limited lifetime warranty. The following cases will void the warranty: Misuse, dropping, or any other noticeable cosmetic damage.
Q What is the range of the LT-803-072 transmitter?
A Line of site up to 305 m (1,000 ft.) with remote antenna.
Q Does the LT-803-072 include the rack mount?
A No, but an LA-326 Universal Rack Mounting Kit is available for purchase. Antenna options for rack mounting also available.
Q Is there a limit to the number of LT-803-072 transmitters I can use in one room?
A Yes. The maximum is (3) three.
Q Is the LT-803-072 compatible with Listen's other receivers (LR-300-072, LR-400-072, LR-500-072, LR-100-072, and LR-600-072)?
A Yes. Remember, the LT-803-072 has only three (3) channels (A, E, H) therefore the receiver will need to be tuned to one of those channels. Also, the SQ (Super Quiet) function must be turned off on the receiver.
Q Do I need a transmitter for each audio source?
A Each audio source requires a transmitter.
Q How many receivers can I have on a system?
A As many as you want. The transmitter simply transmits a signal and you can have as many receivers pick that signal up as necessary. It's like a radio station transmitting and the receivers are the radios tuning into the "channel".

We've been impressed by the Listen system's ease of use (and installation), as well as its flexibility. The difference between your system and what we had been using is amazing. Patrons are happy and thus, so are we.
