Listen Technologies LA-140

The Listen Technologies LA-140 IR radiator/emitter packs high infrared power in a small and attractive design.

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 RG-58 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 for auditory description.

  • Outstanding coverage - 10,000 square feet (929 square meters)
  • Two radiators can be powered from one LT-82 transmitter or optional power supply using standard CAT-5 cabling - eliminating the need for multiple cables
  • White or grey color - allows for a variety of aesthetic settings.
