The LR-3200-072 addresses the core challenge facing houses of worship, theaters, and conference venues: providing clear, reliable assistive listening without burdening staff or end users. Its compact form factor—the smallest in its category—simplifies dispensing, storage, and user adoption. The integrated neck loop with DSP loop driver ensures optimal compatibility with T-coil hearing aids, while dual 3.5mm jacks enable shared listening or personal headphone use.

Built for integrators managing large inventories, the receiver connects via micro USB to iDSP software for centralized programming, charging, and firmware management. The lithium-ion battery eliminates recurring alkaline costs and provides 24 hours of continuous operation, supporting extended services and multi-session events without recharging interruptions.

With best-in-class RF sensitivity down to 0.6 µV and 17-channel expandability, the LR-3200-072 fits single-channel ADA compliance installations and scalable multi-zone facilities alike. FCC Part 15 Class B and RoHS compliance ensure deployment readiness across regulated environments.
