This 216 MHz LISTEN Technologies Intelligent DSP RF Receiver is an iDSP (Intelligent Digital Signal Processing) personal listening product. Thanks to its DSP SQ noise reduction technology, users experience 20 dB less noise than similar devices without it. The green battery technology 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-4200-216 has an OLED screen to display channel names, monitor battery status, channel status, and charge activation. You may connect the iDSP neck loop/lanyard or earphones via one of two 3.5mm output jacks, so the receiver can be shared with another user. 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.
