The LR-4200-072 Intelligent DSP RF Receiver from Listen Technologies offers outstanding audio clarity and quality with the best range and reception in its class. The LR-4200-072 is the smallest device of its kind and a member of our Intelligent Digital Signal Processing (iDSP) series, creating a tiny gadget that won't burden the user. Each receiver is simple to wear thanks to an integrated neck loop/lanyard, and the DSP loop driver improves listening for anybody using a hearing aid with a T-coil. Dual 3.5mm output jacks also allow receivers to be shared between users.

Each receiver is equipped with a micro USB connection which can be used with free iDSP software for charging, set up, programming, inventory management and firmware updates. Extended speaking sessions, presentations and more can be challenging for other devices, but the LR-4200-072 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 classrooms to boardrooms, conferences and more, the LR-4200-072 is an outstanding receiver choice for any venue looking to offer convenient, reliable assistive listening.
