XLR 3-Pin Male to BNC Female Adapter

The Boxwave XLR 3-Pin Male to BNC Female Audio Adapter converts between professional XLR and BNC coaxial connectors. It enables direct connection of microphones, amplifiers, or mixing consoles to video systems, RF equipment, or broadcast gear using BNC inputs. The unbalanced wiring links XLR pins 1 and 3 to the BNC shield and pin 2 to the centre conductor.

Metal Shell Shielding and Passive Operation

A rugged zinc alloy die-cast housing with gold-plated contacts provides effective shielding against electromagnetic and radio-frequency interference. The adapter maintains stable signal integrity for both high and low-frequency analog signals without active electronics. It draws no power and adds no noise to the signal path during normal use.

Unbalanced Wiring Configuration

The internal wiring connects XLR Pin 1 (Shield) and Pin 3 to the BNC shield while XLR Pin 2 (Signal +) connects to the BNC centre conductor. This fixed unbalanced topology means the adapter cannot preserve balanced audio signals or provide impedance matching for balanced lines. Buyers who need balanced signal transmission should not use this adapter.

Questions about this item

How do I wire the XLR 3-pin male to BNC female adapter for an unbalanced signal?

Connect XLR pin 1 (shield) and pin 3 to the BNC shield, and XLR pin 2 (signal +) to the BNC center conductor; the adapter's internal wiring follows this unbalanced configuration.

Will the gold-plated contacts or zinc alloy housing need replacement over time?

Gold-plated contacts resist oxidation and the zinc alloy die-cast housing is built for long-term durability; neither component has a specified replacement interval under normal use.

At what point does EMI shielding become the limiting factor during extended cable runs?

The robust metal shell provides effective EMI/RFI shielding for reliable analog signal transmission, but shielding effectiveness over very long distances depends on the overall cable quality and environment.
