The LT-800 transmitter connects 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. Auditory assistance is aided by installing the transmitter with your facility's main audio system. This can also help public facilities meet the Americans with Disabilities Act (ADA). Use with the Listen LR-400 Personal Receiver, LR-500 Portable Programmable FM Receiver and Listen LR-600 Wireless FM Receiver/Speaker. The Listen LT-800 Stationary Transmitter is available in both the 72MHz and 216MHz frequency ranges, with 57 channels in each frequency range. This means you are sure to find a clear signal, and can use up to five Listen LT-800 Stationary Transmitters in the same area (often used for simultaneous interpretation) in the 72MHz frequency (three in 216MHz). Remote amplification (also referred to as soundfields) can be achieved using the LT-800 and Listen's LR-100 Stationary Receiver/Power Amplifier or the LR-600 Wireless Speaker Receiver. Language interpretation (including multiple simultaneous interpretations) can utilize a sound booth (a separate area or room where the interpreter can speak and not disturb the rest of the audience), and broadcast the interpretation with an LT-800 to individual receivers. Highlights: A choice of 72 or 216 MHz systems, complete antenna and accessory options and superb audio quality 216 MHz system offers double the range of more familiar 72 MHz systems - up to 3,000 feet (914m) 80dB signal-to-noise ratio, setting the industry's sound quality standard Phantom Power: allows users to directly connect higher quality microphones (including condenser mics) to the LT-800 balanced microphone input without the need of an outboard mixer or phantom power supply.
