Listen LS-58-072-D iDSP Advanced Level III Stationary RF System 72 MHz - Dante Supported LS-58-072-D

Ready to install and ideal for large or growing venues, the LS-58 Advanced Level III Stationary RF System utilizes Listen's LT-800-072 RF Transmitter, Dante compatible through the use of the LA-465 Dante adapter, and universal antenna kit to provide ample coverage. Complete with four of Listen's LR-5200-072 iDSP multi-channel RF receivers, universal ear speakers, and more, the LS-58 is a high-performance assistive listening solution that gives your listeners outstanding, reliable sound quality.

The LS-58 includes Listen's LA-381 Drop-in Charging/Dispensing Station, with room for charging, storing and managing up to twelve (12) receivers. The high-capacity station makes it easy to upgrade and expand your RF system as the demands of your venue grow.

Each LS-58 also includes an assistive listening notification signage kit to ensure that all visitors are aware of your assistive listening system's availability, and the signage meets legal compliance requirements as well. Combined with the universal antenna kit, rack mounting kit, ear speakers, neck loops/lanyards, and dual RCA cable, the LS-58 is a great choice for venues with a capacity of up to 100 people.
