Listen Technologies LWR-1050 ListenWIFI Wi-Fi audio receiver

General Description

The LWR-1050 is a dedicated receiver to enable a user to listen to a ListenWIFI system. The receiver has a standard 3.5mm socket to connect earbuds, headphones or an LA-438 neck loop (for use with hearing aids that have telecoils). 

This receiver allows the user to connect to ListenWIFI Audio Servers to hear crystal-clear audio streams in real-time.

Receivers are ideal for venues to issue to guests that do not have a smartphone with the ListenWIFI app.

The LWR-1050 can automatically switch to the appropriate channel based on its location with the help of LA-490 Bluetooth/IR Beacons. These ensure a seamless audio experience in venues that operate with multiple channels. Making them ideal for use in concerts halls, theatres, exhibitions spaces, stadiums, sport bars, airport lounges, museums, music festivals, college campuses, places of worship and many other places.
