●LK-1 (LK1) is a transmitter and receiver of the ListenTALK wireless communication system manufactured by Listen Technologies, operating in the 1.9GHz band (DECT method). It plays a central role in ListenTALK. ●ListenTALK is a bidirectional wireless communication system that uses the 1.9GHz frequency band, making it resistant to interference. It is robust against noise and radio interference, allowing for hands-free use without affecting medical devices. Due to the DECT method operating at 1.9GHz, there is minimal interference and radio disruption. It does not interfere with wireless devices operating in the 2.4GHz band at all. ●LK-1 allows for unlimited simultaneous communication in half-duplex mode. In hands-free simultaneous communication, it can support up to 3 devices. It can be configured for a maximum of 20 groups. ●As a wireless guide system, LK-1 can stream audio to separately sold receivers (LKR-11, LKR-12). ●In half-duplex communication or when used as a transmitter, unlimited additional units can be added for one speaker (leader terminal). *For more details, please refer to the PDF document or feel free to contact us.*
