Listen Technologies LA-141 ListenIR Expansion Radiator for LT-84

Optimize and extend the LT-84 infrared system for uninterrupted assistive listening across larger spaces. The Listen Technologies LA-141 ListenIR Expansion Radiator is a purpose-built infrared radiator that boosts coverage and fills gaps, ensuring patrons, visitors, and attendees receive reliable, high-quality audio. Install up to four LA-141 units to expand coverage up to 2,787 m2 (30,000 ft2) with LR-4200-IR/LR-5200-IR receivers or up to 697 m2 (7,500 ft2) with LR-42/LR-44 receivers in single-channel mode. A single CAT-5e cable supplies both power and signal, reducing installation time and ongoing maintenance costs. Its low-profile, lightweight form and included mounting hardware make it ideal for retrofits and new builds in environments that require dependable monitoring and clear communication — from security command centers and surveillance control rooms to public assembly venues. RoHS and WEEE compliance also supports sustainability goals. Add LA-141 radiators to your ListenIR LT-84 system for seamless, gap-less audio distribution — contact us to specify the right configuration for your venue or integrate with your security and monitoring infrastructure today.
