Listen Tech LS-53-072 Listen iDSP Premiere Level I Stationary RF System (72 MHz)

Product Overview

The Listen Technologies LS-53-072 is a single-channel iDSP Level I stationary RF assistive listening system on the 72 MHz band, packaged for fast deployment in commercial venues. It pairs the LT-800 Stationary RF Transmitter (72 MHz) with four LR-4200-072 iDSP RF Receivers and the accessories needed to begin offering RF assistive listening immediately. Advanced iDSP signal processing delivers cleaner audio than conventional RF, making it a practical compliance solution for permanent installations.

Product Description

The LS-53-072 is built around Listen's iDSP (Intelligent Digital Signal Processing) receiver platform, which the manufacturer rates at 20 dB less hiss than other RF receivers for noticeably clearer assistive listening. Each LR-4200-072 receiver uses a field-replaceable, non-proprietary rechargeable lithium-ion battery rated at roughly eight hours of use with a 2.5-hour charge, removing the cost and waste of disposable batteries. Integrated neck loops improve the experience for listeners with telecoil-equipped hearing aids and cochlear implants. The included LA-106 telescoping antenna provides transmitter range for the room, and the LA-304 notification signage kit supports ADA compliance. Universal ear speakers, neck-loop lanyards, a four-port USB charger, and an RCA cable round out a single-channel RF system ready to install in conference rooms, training rooms, and similar commercial meeting spaces.
