About Listen Technologies LS-54-072

Configured with permanent installations in mind, the LS-54 Stationary RF System comes with everything needed to immediately integrate and offer high-quality assistive listening while meeting compliance requirements.

Beginning with the LT-800-072 Stationary RF Transmitter and LA-122 Universal Antenna Kit, the system allows you to configure and rack mount the antenna ideal for your system and setup.

Four of our advanced LR-4200-072 iDSP Receivers are included as well, along with four universal ear speakers, two intelligent neck loops/lanyards, a four-port USB charger, RCA cable, and a notification signage kit. The result is a complete assistive listening system that provides outstanding audio performance and immediate compliance for your business or venue.

Architectural Specs
Furnish and install an RF wireless assistive listening system for use by the hearing-impaired. The assistive listening system (ALS) shall be capable of broadcasting on 57 channels and be frequency agile. The RF receiver shall be capable of receiving on 57 wide and narrow band channels. The device shall tune to a single channel and user shall not be able to change the channel. The receiver shall have a signal-to-noise ratio of 80 dB or greater and shall have an audio frequency response of 50 Hz - 15 kHz ( +/-3 dB). The device shall employ a unique DSP SQ noise reduction technology.

The unit shall have a programmable squelch circuit. The unit shall incorporate a multi-functional display that indicates battery status, inventory number and channel. The device shall have the option of being lanyard or belt clip worn and the lanyard shall have the option of an integrated DSP driven neck loop that automatically senses and sends optimized audio signals directly to hearing aids and cochlear implants equipped with telecoils. The neck loop shall have a field strength of 400 mA/m (+/- 3dB) and frequency response of 100Hz to 5kHz (+/- 3 dB ref 1kHz).

The device shall have a USB connector used for inventory control, set up, charging and firmware upgrades. The device shall incorporate automatic battery charging circuitry and use a non-proprietary lithium ion battery. The device shall have additional charging contacts to allow multiply charging options. The ALS system shall have 80dB SNR or greater, end-to-end. Listen Technologies Corporation products are specified.
