Panel adapter Procab VC3MDL — 3‑pin male XLR panel connector

Procab VC3MDL panel adapter is a 3‑pin male XLR panel connector designed to provide secure and standardised audio and signal connections through equipment panels. The adapter offers a panel‑mount housing that fits into racks, consoles or custom enclosures and presents a fixed male XLR interface for wiring on the equipment side. It is intended for professional audio installations where a durable, serviceable connector is required for microphone, line or control signal routing.

Advantages

The adapter features a compact panel‑mount design that maintains the conventional 3‑pin XLR pinout for compatibility with microphones, mixers and other audio devices. Its metal housing ensures mechanical stability and shielding against physical stress and contact movement. The fixed male XLR interface simplifies cable mating and replacement while providing consistent contact pressure for reliable signal transmission. The unit is suitable for permanent installation and routine use in studio, stage and broadcast environments.

Suitable for

• Panel mounting in audio racks, consoles and equipment enclosures
• Creating permanent microphone and line input/output points
• Signal routing in live sound, studio and broadcast installations
• Custom panels and repair or replacement of existing panel connectors

Key specifications

• Connector type: 3‑pin male XLR (panel mount)
• Housing: metal panel housing for secure mounting
• Contact configuration: standard 3‑pin XLR pinout for balanced audio
• Mounting method: panel cutout with fastening hardware (screw/lock)
• Application: audio and low‑voltage signal connections

How to use

Prepare the panel cutout to match the adapter’s mounting dimensions and secure the housing using the provided fastening method. Wire the internal contacts to the corresponding cable or internal wiring, following the standard XLR pinout for balanced audio: pin 1 = ground, pin 2 = hot (positive), pin 3 = cold (negative). After wiring, verify that the connector is mechanically secure and that there are no exposed conductors. Mate the panel‑mounted male XLR with standard female XLR cables for normal operation.

Usage recommendations

For best performance, use the adapter in dry, protected equipment racks or enclosures and ensure proper strain relief on connected cables. Periodically inspect the contacts and mounting hardware for corrosion or loosening; clean contacts with appropriate contact cleaner if necessary. When installing in environments with frequent cable movement, confirm that mounting and cable routing reduce mechanical stress on the connector.
