Listen Technologies Advanced Intelligent DSP RF Receiver (72 MHz)(Listen Technologies Advanced Intelligent Dsp Rf Receiver 72 Mhz)

The Advanced Intelligent DSP RF Receiver from Listen Technologies is an advanced iDSP IR receiver. It features DSP SQ noise reduction technology, allowing users to experience 20 dB less noise and hiss. 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.

The unit has an OLED display to program channel names, monitor battery status, channel status, and charge activation. Programmable channel select summary allows user to cycle through active channels, seek to, or lock to a channel. Connect the iDSP neck loop/lanyard or ear phones via two 3.5mm output jacks (ear phones could be shared). The micro-USB connection is used with the included iDSP software for charging, set up, programming, inventory management, and firmware updates.
