Product Overview
Listen makes it easy to add assistive listening to your venue with their Advanced level packaged systems.
The Listen LS-56-072 is an Advanced level I system designed to provide a quick and easy assistive listening solution for venues with a capacity of up to 100 people. The Advanced systems expand upon the Prime level systems by stepping up to the Listen LR-5200 intelligent DSP receiver with 4-port USB charger. The 5200s iDSP (intelligent digital signal processing) 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-56 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 board meetings, in-ear cueing, training sessions, auditory assistance, and more. Universal inputs on the transmitters ensure you can use the LS-56 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-56-072 comes with Listen's LR-5200 receiver that operates only in the 72 MHz frequency range.
