Listen makes it easy to add assistive listening to your venue with their Advanced level packaged systems.

An Advanced level III system, the LS-58-072 expands upon the LS-57 system by adding an intelligent 12-unit charging tray so you can expand your system and make sure your always fully charged. The included LR-5200 iDSP (intelligent digital signal processing) receiver means users with tele-coil hearing devices will enjoy an improved listening experience, and dual 3.5mm outputs allow two listeners to share a single unit. An OLED display shows device settings, channel information, and battery level, allowing you to check system status at a glance. The LS-58 includes all of the needed system components and compliance verification you need to function right out of the box.

After a simple set up you'll have a system that's suited to a wide range of audio applications including lecture halls, public meeting rooms, playhouses, theaters, and more. Universal inputs on the transmitters ensure you can use the LS-58 with your preferred audio source; mixer, microphone, iPod or CD. Your users will enjoy Listen's Super Quiet technology that delivers audio with 20dB less noise than competing systems, leaving them with a more memorable overall experience.

The LS-58-072 comes with Listen's LR-5200 receiver that operates only in the 072 MHz frequency range.
