Thanks to its outstanding audio quality, the Listen LT-800
Stationary Transmitter can be used in a variety of applications.
The LT-800 can be connected to your main audio system to
broadcast a high quality audio signal to belt pack receivers,
stationary receivers, or wireless speaker/receivers (72/216MHz
only). 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 earphone.

programming information. It has multiple audio inputs with level
control and mix level control. It also includes a test tone for tuning.
