The XLR plugs from Red River are gold-plated and feature arrows on their stems to indicate the direction of the cable.

The connectors in the Red River series complement the Bulk Spool cables of the River series, allowing for their construction and termination to suit various needs.

These specific connectors allow for solderless connections, using a high-pressure technique for terminating the signal cable and grounding. This process has beneficial effects on the sound performance of the system.
