The MH-01-01 system comes equipped with MH-5200-072 receivers (LR-5200-072 with customized programming), Listen’s new generation of personal listening products, iDSP or Intelligent Digital Signal Processing. The system also includes the MH-800-072-01 transmitter (LT-800-072-01 with customized settings).
The new integrated neck loop/lanyard improves the experience for people who have hearing aids and cochlear implants with telecoils. Sleek and small, the iDSP receiver has a field replaceable, non-proprietary rechargeable lithium-ion battery, making obsolete the use of alkaline and NiMH batteries. Battery life is eight hours, with a 2.5-hour charge time.
The result is an innovative personal listening technology and solution that delivers an exceptional listening experience for users and an optimal experience for the venue that provide provides listening devices.
Great for large meeting houses to deliver an optimum range of up to 305 m (1,000 ft). Includes the LA-381-01 drop-in charging/dispensing station. Engineered for streamlined dispensing, collecting and care of the iDSP LR-5200 RF listening devices. The charging tray can be mounted several ways; wall, drawer, rack, or table top- all for easy dispensing.
