The Listen Technologies LT-800 provides professional-grade RF transmission for fixed assistive listening installations in houses of worship, theaters, courtrooms, and conference centers. With dual input paths—balanced XLR/combo and unbalanced RCA—it integrates seamlessly into existing audio infrastructure. Fifty-seven selectable channels accommodate multi-room venues while the built-in compressor and contour filter optimize voice and music reproduction before broadcast.

The Look & Listen LCD provides at-a-glance channel status, lock confirmation, and RF power level monitoring, eliminating guesswork during installation and daily operation. Front-panel VU metering and test tone simplify gain staging with belt pack and stationary receivers up to 1,000 feet away. Half-rack form factor allows single or dual mounting in standard equipment racks.

Designed for permanent installations requiring FCC Part 15 and Part 90 compliance, this transmitter supports up to eight simultaneous units for large or complex venues. The LA-207 power supply and channel lock programming ensure long-term stability across seasonal temperature and humidity variations.
