Description
The LA-141 Expansion Radiator (Pat. 9,712,246) from Listen Technologies expands on the functionality and coverage area of the LT-84 Infrared Transmitter/Radiator combo system, giving users and clients an uninterrupted, high-performance listening experience.
Up to four (4) LA-141 Expansion Radiators can be added to the LT-84 system, providing additional coverage up to 2,787 m2 (30,000 ft2) with LR-4200-IR/LR-5200-IR receivers or 697 m2 (7,500 ft2) with LR-42/LR-44 receivers in single-channel mode. A single CAT-5e cable provides both power and signal to the radiators, and the included mounting hardware and single-cable design make installation and setup a breeze.
Features:
- The only product of its kind that provides complete, gap-less coverage in small- to mid-size spaces
- Up to four radiators can be added to the LT-84 system providing additional coverage up to 2,787 m2 (30,000 ft2)
- Single-cable CAT-5e provides power and audio signal for ease of setup
- Simple installation with the included mounting hardware
Includes:
- One (1) LA-141 ListenIR Expansion Radiator
- One (1) 25 ft. (7.6 m) CAT-5e Cable
- One (1) LA-344 Flexible Mounting Hardware
- One (1) Quick Start Guide
