The ATLK-EXT165 link extender allows users to extend the cable runs in compatible discussion and conference systems and mixers equipped with Audio-Technica LINK ports. When used with the ATUC-50 Digital Discussion System, it enables an increased discussion unit count of up to 100 DUs per ATUC-50CU control unit . The extender is equipped with two RJ-45 Audio-Technica LINK ports through which it supplies DC +48V power to connected devices. It can be set to power on/off automatically in tandem with a connected control unit or to operate locally, powering on/off with the press of the extender's Mode switch. The front of the unit is equipped with LED indicators that display power on/off of the extender and status of power supplied to connected devices. Another LED will blink, and the extender will stop supplying power, if a current overload (above 2.6A) is detected at the LINK ports. The ATLK-EXT165 comes with the AT8649 table mount kit that allow the extender to be mounted to the underside of a table.
