Thanks to its outstanding audio quality, the Listen LT-800 Stationary Transmitter can be used in a variety of applications.
The LT-800 is connected to your main audio system, broadcasting a high quality audio signal to belt pack receivers,
stationary receivers, or wireless speaker / receivers. The end result – your audience can hear and understand the
presentation better because of improved speaker placement or because they have their own belt pack and headset.
The signature Look & Listen™ LCD shows channel, lock, programming and RF power.

Frequently Asked Questions
Q Does the LT-800 include the rack mount?
A No, but an LA-326 Universal Rack Mounting Kit is available for purchase.
Q Do I need a transmitter for each audio source?
A Yes.
Q What is the range of the LT-800 transmitter?
Line of site up to 1500 ft. (457 m) for 72 MHz.
A Line
of site up to 3,000 ft. (914 m) for 216 MHz.
Q
Line of site up to 400 ft. (122 m) 863 MHz.
Is there a limit to the number of transmitters I can use in one room?
Yes. The 72 MHz LT-800 has a maximum of six. The 216 MHz LT-800 has a maximum of
A three.
The 863 MHz LT-800 has a maximum of eight.
Q How many receivers can I have on a system?
As many as you want. The transmitter simply transmits a signal and you can have as many
A receivers
pick that signal up as necessary. It’s like a radio station transmitting and the receivers are the radios tuning into the “channel”.
