Keep your K4000 and K4000S in sync. Using the DMX Module, link multiple K4000 or K4000S LED Studio Panels together for consistent output and CCT (for K4000S). This user-expandable module is quick to install and perfect for gaining complete control over your K4000/K4000S panels. Similar to the SmartSync Control Circuit, users can link multiple panels together using standard CAT5 ethernet cables. However, users can also fully control their K4000 and K4000S Studio Panels from a DMX capable light board.
