Description
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.
Features- Every Application – A choice of 72 or 216 MHz systems, complete antenna and accessory options and superb audio quality make Listen products ideal for a wide range of applications.Works Where Others Won't – Incorporates the latest, most advanced technology for clear transmission.Double the Range – 216 MHz systems offer double the range of more familiar 72 MHz systems – up to 3,000 feet (914 m).Superior Audio Quality – 80 dB signal-to-noise ratio,setting the industry's sound quality standard.Designed for installation – Rack mountable with remote antennas make installation easy and service reliable.
