LA-140 Stationary IR Radiator/Emitter

The LA-140 IR radiator/emitter packs high infrared power in a small and attractive design, in your choice of grey or white colors. Designed for easy installation using standard components, the LA-140 is powered via CAT-5 cabling while the RF modulated carriers are delivered via standard coaxial cable. Mounting brackets are included for wall, ceiling, desk, mic stand, and tripod mounting. Power can be supplied by the LT-82 transmitter or from a separate power supply (LA-205). Built-in delay compensation prevents signal cancellation (multi-path) problems and eliminates the piled-up cabling that is required with other systems. The LA-140 is used for government compliance (such as ADA), assistive listening, language interpretation, live theatre, houses of worship, courtrooms, secure rooms, and auditory description.

1.LED Indicators The three colored LEDs provide visual indication of power, connectivity, and the presence of a signal. These LEDs can be deactivated in light sensitive rooms.

2.Mounting Hardware and Cable Installation is quick and easy with the included mounting hardware for wall, ceiling, desk (shown), mic stand or tripod. Listen also includes 25 feet (7.6 m) of CAT-5 and coaxial cables (including connectors).

3.RF Section RF from the LT-82 or another radiator is accepted at the RF INPUT BNC. The RF OUTPUT jack feeds RF to additional LA-140 radiator(s). The delay compensation adjustment ensures that all RF signals are transmitted by the radiator at the same time, thereby eliminating receiver drop outs created when signals are out of phase. The TERMINATION switch terminates the coaxial cable on the last radiator in the daisy chain.

4.Power Section The CAT-5 POWER INPUT connector accepts power from the LT-82 transmitter, from an optional LA-205 power supply or from another LA-140 radiator. The POWER OUTPUT connector provides power for up to one additional radiator. The dip switches are for setting options.
