Under the umbrella of advanced communication systems, the LKS-7-A1 ListenTALK R8 System stands out with its superior features and robust performance. This portable wireless communication system is designed for seamless one-way communication between one leader and up to seven participants. It's an ideal solution for various scenarios including guided tours, training sessions, and simultaneous interpretation.
The ListenTALK R8 System operates on the 1.9 GHz unlicensed PCS band, leveraging Frequency-Hopping Spread Spectrum (FHSS) techniques for interference-free communication. It employs a multi-layer security protocol, including a 40-bit group subscription, 32-bit authentication, and a 64-bit encryption scheme, ensuring secure transmission of information.
The system is user-friendly, with easy pairing and group formation via the Docking Station or Software Suite. It features simple operation controls with Power, Volume Up, and Volume Down buttons. The devices can support up to 10 simultaneous groups operating in the same area, making it a versatile choice for large-scale events.
Powering the system is a removable, non-proprietary rechargeable lithium-ion battery, with an optional compartment for 3 AAA alkaline batteries. The devices come with a 3.5 mm TRRS CTIA compliant headset connection, compatible with a standard electret style headset.
The leader device of the system, the LK-1 Transceiver, is equipped with a 64 x 128 OLED display with auto-dimming, providing a clear view of all current status indicators. It also features a built-in microphone with auto-detect circuitry, allowing users to use their personal earbuds. The leader clip designates the unit as a leader, enabling the leader or presenter to control pairing and group creation.
The LKR-12 Receiver Basic is a one-way device designed for participants who only need to listen to the group conversations. It boasts Listen Technologies' ergonomic design, encryption technology for added security, and easy-to-use volume control.
Completing the system is the LA-452 Headset 2 from Listen Technologies. It features a built-in boom mic and earpiece for hands-free communication. The over-the-head design ensures comfort and a secure fit, while the lightweight, compact design and crystal-clear audio performance enhance the user experience.
In summary, the LKS-7-A1 ListenTALK R8 System is a comprehensive solution for one-way communication needs, offering secure, clear, and easy-to-use features for a wide range of applications.
