About Listen Technologies LS-49-072 Listen Premiere Level III Stationary RF System, LT-800-072 Transmitter, 4x LR-400-072 Receiver, LA-317 Charging/Carry Case, 72 MHz

The LS-49-072 Listen Premiere Level III system has everything you need for an easy system to specify, install, operate, and meet legislative requirements for assistive listening. Includes NiMH batteries and a charging/carrying case ideal for managing the storage and dispensing of receivers to listeners. Great for larger venues to deliver an optimum range of up to 305 m (1,000 ft). Includes our LR-400 digital display receivers, which make it easier to monitor channel selection, battery level, and signal strength.

Ideal for applications when assistive listening, single channel language interpretation, and personal use are desired. Venues will benefit from managing the LR-400 when locking on one channel is needed, but programming multiple channels are not or if the receiver channel is not changed regularly by the user. The included neck loops and signage ensures the system meets the minimum legislative requirements for venues with a capacity up to 100.
