The LR-5200-072 brings professional-grade DSP processing to assistive listening installations where space, budget, and audio quality all matter. Designed for houses of worship, performing arts centers, conference facilities, and educational venues, this 72 MHz receiver combines best-in-class RF sensitivity with a body size 30% smaller than legacy models, making it easier to deploy, wear, and maintain across large listener populations.
Lithium-ion rechargeable battery technology delivers eight hours of continuous operation and eliminates the recurring cost and waste associated with disposable cells. Micro-USB charging and firmware updates simplify fleet management, while iDSP software enables venue-specific programming including channel lockouts, volume limits, and custom labeling. The integrated neck loop with onboard DSP loop driver ensures consistent induction field strength for T-coil users without external amplification.
Built-in OLED display provides real-time feedback on channel selection, battery status, and audio levels, reducing help desk calls and improving user independence. Wide-band and narrow-band channel modes support legacy and high-density RF environments, making the LR-5200-072 a future-ready choice for AV integrators managing assistive listening mandates and ADA compliance.
