ProCo Sound DOC4U 4 Universe DMX Break Box | Out | Truss Clamp

The ProCo Sound DoC4U series is engineered for lighting technicians, touring production crews, and install integrators who need to transport multiple DMX universes over long-distance structured cabling infrastructure. By converting four independent DMX lines into a single Neutrik EtherCON connector, the DoC4U eliminates the need to run multiple individual DMX cables across large venues, stages, or permanent installations.

The break-in and break-out box pairing allows AV and lighting teams to deploy reliable DMX distribution over CAT6 or CAT5e cable runs that are already present in a facility or rigged into a touring rig — reducing cable weight, complexity, and failure points at the same time. Whether managing a festival main stage, a fixed theatrical installation, or a corporate event with distributed lighting zones, the DoC4U system provides a clean, repeatable solution for multi-universe DMX transport.

Each variant in the DoC4U family shares the same core signal conversion architecture and Neutrik EtherCON connectivity, with mounting options available to suit different deployment environments. The standard version suits applications where dedicated mounting hardware is not required.
