General Description

The LA-140 Infrared radiator/emitter packs high infrared power in a compact and attractive design. This unit is designed for easy installation and is supplied complete with wall, ceiling, desktop, mic stand and tripod mounting brackets. The LA-140 is powered via CAT-5 cabling while the RF modulated carriers are delivered via standard coax cable.

Power can be supplied by the LT-82 transmitter or from a separate LA-205 power supply (not supplied). 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 assistive listening, audio description or language interpretation.
