Audio Ground Lifter

The Hosa Technology XLR3F to XLR3M Ground Lifter is an audio component designed to remove ground-loop hum from balanced signal paths. It connects between a male XLR output and a female XLR input, lifting pin one to break the ground connection while passing audio unchanged. The adapter suits live sound, broadcast and studio environments where interconnected gear creates audible buzz.

Connection Check

Verify that both devices in the signal chain use standard three-pin XLR connectors and that the source provides a balanced output. Confirm the hum disappears when the shield is lifted at one end, as some systems require a grounded reference for phantom power or noise rejection. Ensure the adapter orientation matches the direction of signal flow from output to input.

Build Integration

The barrel-style body inserts directly into the cable run without extra cables or power, freeing rack space and patch-bay ports. It isolates the shield on a single channel, allowing the rest of the system to remain grounded. The passive design adds no active circuitry, so it introduces no latency, distortion or colouration to the audio path.

Questions about this item

What connectors does the Hosa XLR3F to XLR3M Ground Lifter use?

It has a female XLR3 input and a male XLR3 output, so it plugs inline between a microphone or line-level source and the next piece of gear without extra cables.

Is there more than one version of this ground lifter to choose from?

The product is offered as a single model with XLR3F-to-XLR3M wiring; no alternative pin counts, colours or form factors are listed.

What does lifting Pin 1 actually do for the audio signal?

It breaks the ground connection between the two XLR devices, stopping ground-loop current that causes hum while keeping the audio signal path intact.
