Experience the power of comprehensive auditory assistance with the LS-88-01 Portable ListenIR iDSP system. Designed to meet all IBC and ADA requirements, this system is perfect for small to medium-sized rooms, accommodating up to 50 individuals. It's a portable solution, easily transported and stored in its dedicated carrying case, making it ideal for a variety of settings, from classrooms and conferences to boardrooms and jury deliberation rooms.
The LS-88-01 system is more than just a transmitter; it's a complete package that includes a ListenIR Transmitter/Radiator Combo, receivers, ear speakers, and neck loop lanyards for multiple users, along with other necessary equipment. It's designed to provide on-demand assistive listening, ensuring that everyone in the room can participate fully.
This advanced assistive listening system (ALS) is capable of broadcasting up to two audio channels, offering a choice of four mono carrier frequencies: 2.3, 2.8, 3.3, and 3.8 MHz. With single channel transmission, the system can cover an area of up to 30,000 ft2 (2787 m2). It boasts a signal-to-noise ratio (SNR) of 60 dB or better and total harmonic distortion (THD) of less than 2%, ensuring clear, high-quality sound.
The system's audio frequency response ranges from 63 Hz to 15 kHz, +/- 3db, and includes an omnidirectional tabletop microphone for optimal audio pickup. The receivers are tuned to a single channel, with no user ability to change the channel, ensuring a consistent listening experience for all users. They 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. They feature two 3.5 mm (TRRS) connectors to drive the integrated neck loop lanyard or up to two mono or stereo earphones. A multi-functional OLED display indicates battery status, inventory number, volume level, and a customizable channel name.
Incorporating unique iDSPTM noise reduction technology, the receivers are fully programmable via PC software and feature a micro USB connector for programming/setup, inventory control, charging, and firmware upgrades. They use a non-proprietary lithium-ion battery and incorporate automatic battery charging circuitry. The receivers automatically turn on when removed from the charging device and turn off when returned, adding to the ease of use. Experience the LS-88-01 Portable ListenIR iDSP system, a complete solution for assistive listening needs.
