About Listen Technologies LS-95

Explore the LS-95 IR Advanced iDSP Level III System, a comprehensive audio solution designed to cater to venues with up to 100 seats. This system is inclusive of the LT-84 Transmitter/Radiator Combo, four LR-5200-IR Advanced iDSP Receivers, a 12-unit charging tray, a log book, and the LA-382 Cable Management Unit, providing everything necessary to deliver a superior assistive listening experience.

Ideal for classrooms, boardrooms, theaters, meeting spaces, and a myriad of other environments, the LS-95 ensures secure audio transmission and exceptional signal clarity. This IR wireless assistive listening system is designed to aid the hearing-impaired, boasting the capacity to broadcast up to two audio channels with a choice of four mono carrier frequencies; 2.3, 2.8, 3.3, and 3.8 MHz.

The system's coverage area extends up to 30,000 ft (2787 m) with single channel transmission, and it guarantees a Signal-to-Noise Ratio (SNR) of 60 dB or better and Total Harmonic Distortion (THD) of less than 2%. With an audio frequency response of 63 Hz to 15 kHz, +/- 3db, the LS-95 delivers clear and crisp sound.

The system features two independent mixing audio inputs, each consisting of a 3.5 mm Microphone input, a balanced Phoenix type input, and an unbalanced RCA input. It also includes independent channel audio processing with Limiting, Compression, and Noise Gate, as well as transmit level control and level indication via an LED.

The LS-95 system can provide Power and RF signal for up to four Expansion Radiators over CAT-5 cable for additional coverage. The receivers are capable of receiving on four wide band channels and have a programmable multi-function Listen button that can be tuned for the venue's desired channels and electronically lock out any unused channels.

The receivers can be worn with a lanyard or belt clip, and the lanyard incorporates an integrated neck loop for compatibility with T-coil hearing aids. The receivers are intelligent, providing customized audio to either earphones or the integrated neck loop based on which is connected.

Each receiver features two 3.5 mm (TRRS) connectors to drive the integrated neck loop lanyard or up to two mono or stereo earphones. They also incorporate a multi-functional display (OLED) that indicates battery status, inventory number, volume level, and a customizable channel name.

The receivers employ unique iDSPTM noise reduction technology and are fully programmable via PC software. They have a micro USB connector used for programming/setup, inventory control, charging, and firmware upgrades. The receivers use a non-proprietary lithium-ion battery and incorporate automatic battery charging circuitry. They automatically turn on when removed from the charging device and turn off when returned to the charging device, offering multiple charging options.
