Listen Technologies LKS-1 ListenTALK Base-4 Two-Way Communication System

The Listen Technologies LKS-1 ListenTALK Base-4 System is a complete portable wireless communication solution designed for small groups that need clear, reliable two-way conversations. Ideal for guided tours, educational programs, manufacturing facilities, corporate training, and event coordination, this four-person ListenTALK system allows one leader and up to three participants to communicate without shouting or gathering closely together.

Unlike traditional one-way tour guide systems, the ListenTALK LKS-1 supports two-way communication, allowing participants to ask questions, share information, and interact with their group leader. This makes it particularly useful for environments where communication, collaboration, and audience engagement are essential.

The LKS-1 includes four LK-1 ListenTALK transceivers with leader clips, one LA-452 over-the-head headset with boom microphone, and one LA-423 four-port USB charger. Each transceiver also includes a rechargeable lithium-ion battery, universal ear speaker, and breakaway lanyard.

Operating in the 1.9 GHz frequency band, ListenTALK uses digital wireless technology with frequency hopping and encryption to provide dependable communication for professional applications.

The system is expandable, allowing organizations to add compatible ListenTALK transceivers as their communication needs grow.

Two-Way Communication for Tours and Group Activities

The ListenTALK LKS-1 is designed for situations where participants need more than a traditional one-way listening system.

A tour guide, instructor, or team leader can communicate with participants while allowing questions and responses during the activity.

This interactive communication is especially beneficial for factory tours, campus visits, training sessions, and educational demonstrations where participants may be spread across an area or working in noisy surroundings.

The included leader clips help configure the system for organized group communication.

Reliable 1.9 GHz Digital Wireless Technology

ListenTALK operates in the 1.9 GHz frequency band and uses Frequency-Hopping Spread Spectrum (FHSS) technology to maintain wireless communication.

By operating outside the heavily used 2.4 GHz Wi-Fi band, ListenTALK can be a practical solution for facilities with numerous wireless devices.

The system also incorporates authentication and encryption technology to help keep group communications secure.

Rechargeable and Ready for Daily Use

Each included LK-1 transceiver features a rechargeable LA-365 lithium-ion battery, helping reduce the need for disposable batteries.

The included LA-423 four-port USB charger provides a convenient charging solution for all four transceivers.

For organizations that conduct daily tours, recurring training sessions, or scheduled events, rechargeable operation simplifies equipment preparation and ongoing battery management.

Expandable ListenTALK Communication System

The LKS-1 provides a practical starting point for organizations introducing wireless two-way communication.

Additional compatible LK-1 transceivers can be added as group sizes increase, allowing the system to grow without replacing the original equipment.

This flexibility makes the ListenTALK Base-4 system suitable for both small organizations and larger facilities planning to expand their communication capabilities.
