Listen Technologies LR-4200-IR Dsp Ir Receiver

Product Description

The LISTEN TECHNOLOGIES LR-4200-IR is an intelligent digital signal processing (DSP) infrared receiver designed for assisted listening applications. It captures infrared audio transmissions and delivers clear, processed sound to the listener through a headphone or earpiece output. DSP-based processing allows the receiver to handle signal conditioning internally, reducing noise and improving audio clarity. Licensed audio technicians, AV integrators, and assistive technology specialists typically install and configure this type of equipment in permanent or portable assisted listening deployments.

The LR-4200-IR is suited for venues and facilities that require assistive listening coverage under ADA guidelines or similar accessibility requirements. Typical installation environments include houses of worship, courtrooms, theaters, conference centers, and educational facilities. The receiver is intended for use as part of a larger infrared assisted listening system, pairing with a compatible IR transmitter and radiator to deliver audio to end users who require hearing assistance or language interpretation services.

• Intelligent DSP processing for improved audio clarity and noise reduction
• Infrared reception technology for contained, room-specific audio coverage

Installation Notes

Installation and system configuration should be performed by a qualified AV integrator or assistive technology specialist familiar with infrared audio distribution systems. Power down the transmitter and associated equipment before connecting or servicing the receiver. Placement of IR receivers should account for line-of-sight coverage from the IR radiators to avoid signal dropout. Installations in public accommodations should be reviewed against applicable accessibility codes and local AHJ requirements.
