Description

The Listen LK-1 is a simple and smart two way communication system found in one device. The new standard in two way communication with the capability of one to one, one to many and two to many portable communications. Ideal for facility and leisure tours, production intercom, assistive listening, training, language interpretation and translation, sports intercom and training or any situation where clear crisp communication and collaboration is required.

The Listen Technologies LK-1 transceiver  utilizes Listen Technologies proprietary encryption technology to ensure security, and provides easy-to-use, push-to-talk implementation in the field for simple coordination and communication among two or more collaborators in any scenario.

User controls such as volume up, volume down, talk, power/status, and pairing help you in tailoring the unit to your particular, moment-to-moment needs. Though the unit can be used with a Listen Technologies headset or standard smartphone earbuds the LK-1 comes with an LA-401 Universal Ear Speaker, as well as a lanyard (useful for on-the-go scenarios), and an LA-365 rechargeable lithium-ion battery. The LK-1 is fully compliant with ADA standards for assistive listening.

With the Listen LK-1 you can choose between listen mode (great for tour groups or seminars) Respond Mode (where participants can listen and respond to leaders only) or Discussion Mode (where participants can listen and respond to leader and group). Creating a group is simple and pairing the leader or leaders (max 2) to the participant units is as simple as touching them back to back or you can pair devices with the push of a button when using the optional docking station.
