Designed for venues that demand reliable assistive listening without burdening users or staff, this receiver combines best-in-class RF sensitivity with a pocket-sized profile that simplifies distribution and storage. The integrated lanyard doubles as a neck loop with digital signal processing circuitry, providing T-coil users a cleaner audio path than passive induction accessories. Dual headphone jacks enable two listeners to share one unit during guided tours or side-by-side training sessions.

Installation teams benefit from micro USB connectivity that supports both charging and firmware updates through standard ports, eliminating proprietary docking hardware. The OLED screen displays channel selection, volume, and charge level without requiring the user to navigate complex menus. Lithium-ion cells deliver eight-hour runtime and recharge fully in two hours, reducing the operational cost and environmental impact of disposable batteries.

Built for lecture halls, conference centers, and worship spaces operating in the 216 MHz spectrum, this receiver balances portability with the RF performance required for large-venue coverage. Its sub-three-ounce weight and belt clip option make it unobtrusive for attendees who need amplification throughout extended programs.
