Listen Technologies Intelligent DSP RF Receiver (72 MHz)

This 72 MHz Intelligent DSP RF Receiver from LISTEN Technologies is an iDSP (Intelligent Digital Signal Processing) personal listening product. With the DSP SQTM noise reduction technology, users experience 20 dB less noise than similar devices without it. The green battery technology dramatically reduces costs of ownership and hassles while reducing the number of batteries in landfills. A field-replaceable lithium-ion battery is included with the unit. The integrated neck loop/lanyard with DSP loop driver, improves the listening experience for T-coil users. This iDSP device is small and easy to wear, dispense, store and maintain.

The LR-4200-072 has an OLED display to program channel names, monitor battery status, channel status, and charge activation. You may connect the iDSP neck loop/lanyard or earphones via two 3.5 mm output jacks and receivers can be shared. The micro-USB connection is used with free iDSP software for charging, set up, programming, inventory management and firmware updates. This listening device is suited for places where it's difficult to hear, such as theaters, lecture halls, concert venues, and houses of worship.
