Listen Technologies Basic DSP RF Receiver (72 MHz) - LR-3200-072

Description

Basic DSP RF Receiver (72 MHz)

The LR-3200-072 receiver from Listen Technologies offers outstanding audio clarity and quality with the best range and reception in its class.

Part of our Intelligent Digital Signal Processing (iDSP) line, the LR-3200-072 is the smallest device of its kind, resulting in a compact unit that won’t burden the end user. An integrated neck loop/lanyard makes each receiver easy to wear, and the DSP loop driver offers an improved listening experience for anyone with a T-coil-equipped hearing aid. Dual 3.5mm output jacks also allow receivers to be shared between users.

Each receiver is equipped with a micro USB connection which can be used with free iDSP software for charging, set up, programming, inventory management and firmware updates.

Extended speaking sessions, presentations and more can be challenging for other devices, but the LR-3200-072 incorporates advanced Lithium-ion rechargeable batteries that offer long life and reliable power.
