Under the banner of sophisticated audio solutions, the LS-94 ListenIR Advanced iDSP Level II System stands out as a state-of-the-art assistive listening package, ideal for enhancing auditory experiences in environments such as courtrooms, classrooms, and venues with seating capacities of up to 50 individuals. This comprehensive system includes the innovative LT-84 ListenIR Transmitter/Radiator Combo, paired with two high-tech LR-5200-IR receivers, providing a seamless and advanced auditory setup for immediate use.
The system's versatility is further enhanced by the inclusion of the LA-381 Intelligent 12-Unit Charging Tray, which simplifies the process of expanding the number of receivers for growing needs. This tray offers a streamlined solution for charging, storing, and managing the receivers, ensuring they are ready for use whenever necessary.
With its exceptional coverage spanning up to 30,000 sq ft (2787 sq m) on a single channel transmission and a superior signal-to-noise ratio (SNR) of 60 dB or better, the LS-94 delivers unmatched clarity and reliability. The system's total harmonic distortion (THD) remains under 2%, and it boasts an audio frequency response from 63 Hz to 15 kHz, +/- 3db, ensuring high-fidelity sound reproduction.
The LS-94 is equipped with two independent mixing audio inputs for each transmission channel, featuring versatile connectivity options including a 3.5 mm Microphone input, a balanced Phoenix type input, and an unbalanced RCA input. Advanced audio processing capabilities such as Limiting, Compression, and Noise Gate, along with transmit level control and LED level indication, are integrated to maintain optimal audio quality.
Designed to accommodate up to four Expansion Radiators via CAT-5 cabling, the system ensures extensive coverage. The LR-5200-IR receivers are adept at receiving four wide band channels, with a programmable multi-function Listen button that can be customized for the venue's preferred channels, while also providing the option to electronically lock out unused channels.
The receivers are designed for user comfort and convenience, offering the flexibility to be worn with a lanyard or belt clip. The integrated neck loop lanyard is T-coil hearing aid compatible, enhancing accessibility for hearing-impaired users. The receivers are intelligent, automatically adjusting the audio output for earphones or the neck loop based on the connected device.
Featuring a multi-functional OLED display, the receivers provide essential information such as battery status, inventory number, volume level, and a customizable channel name. They incorporate iDSP noise reduction technology for crystal-clear sound and are fully programmable via PC software. The micro USB connector serves multiple purposes, including programming, inventory control, charging, and firmware updates.
The receivers utilize a non-proprietary lithium-ion battery with automatic charging circuitry, turning on when removed from the charging device and off when returned, further simplifying operation. Additional charging contacts allow for multiple charging options, ensuring the receivers are always powered and ready for use.
The LS-94 IR Advanced iDSP Level II System by Listen Technologies represents an innovative and sophisticated choice for venues seeking a high-performance, comprehensive assistive listening solution.
