Part of Listen Technologies' iDSP receiver family, the LR-4200-216 features an integrated neck loop/lanyard with a DSP loop driver for use with compatible T-coil-equipped hearing aids, dual 3.5mm audio outputs, an OLED display, programmable squelch, and a rechargeable lithium-ion battery.

216 MHz Assistive Listening Receiver

The LR-4200-216 operates across the 216.0125–216.9875 MHz frequency range and provides:

• 19 wideband channels
• 38 narrowband channels
• 57 total selectable channels
• Programmable squelch with 20 settings
• Automatic squelch when the RF signal is lost

This makes the receiver suitable for Listen 216 MHz RF assistive listening systems used in theaters, houses of worship, classrooms, lecture halls, conference facilities, and other public venues.

Integrated Neck Loop for T-Coil Hearing Aids

The LR-4200-216 features an integrated neck loop/lanyard and DSP loop driver for use with compatible hearing aids equipped with a telecoil or T-coil.

This allows audio from the assistive listening system to be delivered through the neck loop to a compatible hearing aid without requiring a conventional ear speaker.

The receiver can also be used with compatible Listen earphones and other listening accessories.

Dual 3.5mm Audio Outputs

Two 3.5mm audio output connections provide flexibility when connecting compatible headphones, ear speakers, neck loops, or other listening accessories.

The outputs provide a nominal level of 0 dBu with a maximum output of 16mW into a 32-ohm load.

OLED Status Display

The integrated display provides important receiver information directly on the unit, including:

• Channel designation
• Battery level
• Unit number
• Charging status

Simple power and volume controls make the receiver straightforward for users to operate after the system has been configured.

Rechargeable Lithium-Ion Battery

The LR-4200-216 uses an integrated lithium-ion rechargeable battery that provides up to 8 hours of continuous operation.

A full charge takes approximately 2 hours using the receiver's Micro USB charging connection.

An LED provides power and charging information, flashing when the battery is low or while charging and remaining solid when charging is complete.

USB Programming

Receiver settings can be programmed through the USB connection and compatible Listen software.

The RF channel can also be changed directly from the receiver by pressing and holding the volume up and down controls for five seconds and then selecting the desired channel.
