How to use

Strip the cable jacket and separate the conductors according to the cable manufacturer’s instructions. Insert the prepared conductors into the connector contacts following the standard pin numbering for XLR: pin 1 = ground, pin 2 = hot (positive), pin 3 = cold (negative). Secure each conductor under the appropriate contact screw or solder joint depending on the connector variant, then assemble the housing and tighten any retaining screws or strain relief clamps. Verify continuity and correct wiring with a multimeter or cable tester before putting the cable into service.

Usage recommendations

Use appropriate soldering equipment or correct-size screwdrivers for termination to avoid damaging contacts. For permanent installations, apply a suitable strain relief and, where possible, use heat-shrink tubing to protect the solder joints. Test cables after installation to confirm balanced wiring and low resistance connections.
