Description

Listen Tech LS-49-072 Listen Premiere Level III Stationary RF System (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.

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 57 digital channels – Listen receivers are digitally-tuned so the transmission won't drift
  • Look & Listen™ LCD shows channel, battery status, and signal strength
  • Long transmission range ensures coverage for the entire venue
