The LR-4200-IR receiver is one of Listen Technologies’ new generation of personal listening products, iDSP or Intelligent Digital Signal Processing.
The LR-4200-IR is a high performance IR receiver with extreme sensitivity providing the best pickup and range of any device of its kind. iDSP is the smallest device of its kind, making it easy for the end user to wear and operate and easier for the venues to dispense, store and maintain. The integrated neck loop/lanyard with DSP loop driver, improves the listening experience for T-coil users. The advanced 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 LR-4200-IR has an OLED display which shows unique channel names, battery status, channel status, volume status and charge activation. Connect the iDSP neck loop/lanyard or ear phones via two 3.5 mm output jacks (receivers can be shared). The Micro USB connection is used with the free iDSP software suite for set up, programming, inventory management, firmware updates and charging via any standard USB port. The LR-4200-IR is compatible with all iDSP accessories.
The result is an exceptional listening experience in small-to-medium places where it’s difficult to hear, like: theaters, boardrooms, classrooms, courtrooms, houses of worship, and more.
