Overview

Perfect for venues with a capacity of up to 100 people, the LS-57 Advanced Level II Stationary RF System broadcasts a strong, reliable RF signal from our LT-800-072 72 MHz transmitter, and four (4) LR-5200-072 Advanced iDSP receivers ensure the best possible listening experience for customers, clients, visitors, and more.

Our LR-5200-072 receiver offers listeners exceptional audio performance and clarity thanks to having 20 dB less hiss than other RF receivers on the market. Each unit gives listeners the choice of multiple channels, ideal for venues where language interpretation or alternate/separate audio streams are needed. The rechargeable Lithium-ion battery in each receiver offers long life and significant cost savings over the life of each unit, and they fully recharge within 2.5 hours.

The included universal antenna and universal rack mounting kit make the LS-57 an adaptable, flexible solution by allowing you to incorporate it into nearly any permanent audio setup. The system also includesuniversal ear speakers, neck loops/lanyards, a 4-port USB charger, and the assistive listening notification signage kit needed to meet the needs of your customers and ensure your venue’s compliance at the same time.
