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

The ProCo Sound 516 Series EDAC multi-pin receptacle is designed for audio engineers, system integrators, and production teams requiring dense, reliable multi-channel connectivity in touring rigs, installed sound systems, and broadcast infrastructure. EDAC connectors are a standard in professional audio snaking and stage box applications, where a single connector must carry many balanced signals without cross-patching errors.

The 516 Series is available across a range of contact counts, making it a scalable solution whether you are building a 38-channel stage box, a high-density 120-channel audio router, or anything in between. The polarizing keying system ensures connectors cannot be mated incorrectly, which is critical in fast-paced live production environments where mis-patch could take down an entire audio system. The locknut secures the panel-mount installation, preventing accidental disconnection during a show.

For integrators specifying connectors for custom audio snakes, stage boxes, or patch bays, the 516 Series offers consistent construction across the family, simplifying procurement and installation. ProCo Sound's sourcing of these components ensures compatibility with standard EDAC 516-series mating connectors widely used across the industry.
