Listen Technologies LS-58-072 iDSP Advanced Level III Stationary RF System 72 MHz

Stationary RF System 72 MHz

The LS-58-072 is a complete assistive listening package built for large or expanding venues. It combines an LT-800-072 transmitter with four LR-5200-072 receivers and a LA-381-01 charging tray that holds up to twelve units. The system ships with universal ear speakers and a notification signage kit for legal compliance.

72 MHz transmission frequency

The entire system operates on a fixed 72 MHz RF carrier, so every receiver must match that frequency for audio to be received. Venues already using a different band or requiring frequency-agile operation cannot use this kit without replacing all components. The single-frequency design simplifies setup but prevents multi-zone isolation.

Eight-hour continuous runtime

Each receiver runs on a lithium-ion cell rated for up to 8 hours of non-stop listening before the charging tray is required. During back-to-back events the tray must be powered and available to replenish the fleet, otherwise coverage gaps will appear. The transmitter remains mains-powered, so its output does not degrade over the same period.
