User-expandable F&V Lighting DMX Module for the K4000 and K4000S Studio Panels. Similar to the SmartSync Control Circuit, users can link multiple panels together using standard CAT5 Ethernet cables. Users can also fully control their K4000 and K4000S Studio Panels from a DMX capable light board. Link Studio Panels together and keep intensity and CCT (for the K4000S) in sync. Perfect for studio applications for rigged lights needing consistent output and setting.
