ProCo Sound 516 Series EDAC Multi-Pin Plug | With Actuating Screw & Polarizing Hardware | 56 Contacts | Grey Polycarbonate

The ProCo Sound 516 Series EDAC multi-pin plug is designed for audio engineers, systems integrators, and production facilities that require high-density, multi-channel connectivity in touring snake systems, installed audio infrastructure, and broadcast patch environments. EDAC multi-pin connectors are a proven standard in professional audio for consolidating large channel counts into a single, mechanically secure interface, reducing connector count and cable clutter at stage boxes, rack systems, and console tie lines.

Available across a range of contact configurations, the 516 Series accommodates installations ranging from compact studio setups to large-format live production systems. The grey polycarbonate housing provides a lightweight yet durable shell suited to repeated connection cycles in demanding environments. Included actuating screw and polarizing hardware ensure correct orientation on every mate and prevent accidental disconnection — critical in touring and fixed-install applications where reliability between sound check and show time is non-negotiable.

For integrators specifying EDAC wiring on custom snake builds or system retrofits, the 516 Series delivers a field-proven interconnect solution that pairs with standard EDAC-compatible receptacles across leading console and stage box manufacturers.
