Take your assistive listening capabilities to the next level with the LKS-4-A1 ListenTALK Portable ADA Kit, a comprehensive and user-friendly solution designed to meet the needs of individuals with hearing impairments in various environments. This innovative system complies with all IBC and ADA requirements for spaces accommodating up to 75 individuals, ensuring inclusivity and accessibility in listening centers, classrooms, conferences, boardrooms, and houses of worship.
The LKS-4-A1 kit features four LK-1 Transceivers, which are the epitome of high-quality two-way mobile communications. These transceivers are engineered with Listen Technologies' exclusive encryption technology, offering secure, interference-free full duplex communication on the 1.9 GHz unlicensed PCS band. The Frequency-Hopping Spread Spectrum (FHSS) techniques employed by these devices guarantee a crystal-clear connection without the risk of eavesdropping or interference.
Pairing and group formation are made effortless with Near-field communication (NFC), a Docking Station, or Software Suite, allowing for up to 10 simultaneous groups to operate in proximity without conflict. The transceivers are intuitively designed with simple controls for power, talk, and volume adjustments, and feature a 3.5 mm TRRS CTIA compliant headset connection compatible with standard electret style headsets.
The LK-1 Transceiver boasts a durable and portable design, with a leader clip that automatically designates the unit as a leader when inserted, granting the presenter control over pairing, group creation, and talkback modes. The built-in microphone with auto-detect circuitry accommodates personal earbuds, while the 64 x 128 OLED display with auto-dimming showcases all vital information, including group name, volume levels, and battery status.
For extended use, the devices are powered by a removable, rechargeable lithium-ion battery, with an optional compartment for 3 AAA alkaline batteries. Automatic battery charging circuitry ensures your transceivers are always ready for action, whether charged via micro USB port or docking station.
Included in the kit is the LA-451 Headset 1, which pairs perfectly with the LK-1 Transceiver for a seamless two-way communication experience. The headset features a single-earpiece design for exceptional audio clarity, allowing users to stay connected to their surroundings. The built-in boom mic adds convenience for clear conversations, and the lightweight, compact design ensures comfort during extended use.
Durable, high-quality, and portable, the LKS-4-A1 ListenTALK Portable ADA Kit from Listen Technologies is the ideal choice for providing superior assistive listening support in any setting. This innovative and user-friendly system is ready to deliver on-demand assistive listening with minimal setup time, ensuring that every participant can engage fully in the auditory experience.
