Listen Tech LS-47-072 Listen Premiere Level I Stationary RF System (72 MHz)

The LS-47-072 Premiere Level I system comes equipped with 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. Telescoping antenna gives smaller venues the option for using the transmitter within a 198 m (650 ft.) range.

Features

Features

Ensures public venues deliver an enriched listening experience while meeting new legislative requirements for assistive listening
Superior audio quality – 80dB signal-to-noise ratio (SNR), setting the industry's sound quality standard
Offers 57digital channels – Listen receivers are digitally-tuned so the transmission won't drift
