ProCo Sound DMX4U-BI-6 DMX Over Cat EtherCON Breakout Fan

The ProCo Sound DMX4U-BI-6 is part of the DoC (DMX over Category) cable system, designed for lighting engineers and production teams who need to consolidate multiple DMX universes into a single structured cabling infrastructure. The 4-universe break-in fan allows incoming DMX signals from four separate lines to be combined into one Neutrik EtherCON connector, dramatically reducing cable runs across long-distance CAT6 or CAT5e infrastructures found in touring rigs, theatrical installs, and large-scale event production.

The DoC system addresses a practical problem in high-universe-count lighting rigs: managing dozens of individual DMX lines across a venue or stage. By consolidating up to four universes over a single EtherCON-terminated CAT6 run, crews reduce weight on cable runs, simplify patch points, and maintain signal integrity over distances that would challenge conventional DMX cabling. The DoC cables are fully compatible with the DoC4U-I and DoC4U-O break in/out boxes, which are available with eyelet or truss-clamp mounting options for flexible deployment in both flown and ground-based installations.

For production electricians and systems integrators working with multi-universe LED, moving light, or fixture-dense touring systems, the DoC family provides a structured, repeatable cabling solution that scales from two to four universes without switching to a proprietary protocol or additional hardware.
