Overview |
The MH-4200-072 receiver
is an LR-4200-072 with customized programming that incorporates Listen
Technologies’ new generation of personal listening products, iDSP or
Intelligent Digital Signal Processing.
With Listen’s unique DSP audio processing technology, users experience
crystal clear audio that is pleasing to any user, with or without
hearing loss. 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 integrated neck loop / lanyard with DSP loop driver, improves
the listening experience for T-coil users. iDSP is the smallest device
of its kind, making it easier to wear and easier for venues to dispense,
store and maintain.
The MH-4200-072 has an OLED display to program channel names, monitor
battery status, channel 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 for charging and with
the iDSP software suite for programming changes, inventory management
and firmware updates.
The result is an exceptional listening experience in your meeting house
chapel. |
