The Listen Technologies LT-800 offers outstanding audio clarity, digital signal strength, and 57 selectable channels, making it a perfect RF transmitter choice for a wide range of applications.
Connected to your main audio system, the LT-800 broadcasts strong, reliable audio to both belt pack receivers and stationary receivers, ideal for providing listeners with the best possible assistive listening experience. 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 LT-800 features Look and Listen LCD display for quick channel, programming, and channel lock status information, while balanced and unbalanced inputs allow you to connect with a variety of audio sources. It also features a built-in auto processor that optimizes audio (voice or music) prior to transmission. The VU level meter and test tone allow for simple installation and set up.
