Listen Technologies LR-4200-216 Intelligent DSP RF Receiver (216 MHz)

The LR-4200-216 Intelligent DSP RF Receiver (216 MHz) from Listen Technologies offers outstanding audio clarity and quality with the best range and reception available for the 216 MHz band. Because the LR-4200-216 is the smallest of its class, it is a lightweight, portable gadget. It is a component of our Intelligent Digital Signal Processing (iDSP) range and has an integrated neck loop/lanyard for simple wear. The DSP loop driver provides a better listening experience for anyone wearing a hearing aid with a T-coil. Additionally, users may share receivers thanks to dual 3.5mm output connectors.

Each receiver is also equipped with a micro USB connection, making it easy for venues to charge and update the units with free iDSP software via any standard USB port. Extended speaking sessions, presentations and more can be challenging for other devices, but the LR-4200-216 incorporates advanced Lithium-ion rechargeable batteries that offer long life and reliable power. Charge status, along with channel information and volume level, are easy to read on the integrated OLED display. From lecture halls to conferences, classrooms, and more, the LR-4200-216 is an outstanding receiver choice for any venue looking to offer convenient, reliable assistive listening.
