Product description
What’s included: one passive XLR ground isolator with dual XLR connections and a three-position ground lift switch.
Build and materials: housed in a durable metal enclosure with soldered connections for long-term reliability. The unit is compact and feels substantial for its size.
Power: entirely passive — it requires no battery, adapter, or external power source to operate.
Connectors and compatibility: equipped with female and male XLR ports that work with most mixers, amplifiers, microphones, and professional XLR gear.
Size and footprint: small, palm-friendly form factor that won’t dominate a rack or pedalboard and is easy to tuck into a stage or studio signal path.
How to use: insert inline with a balanced XLR cable and select Standard, Semi-Isolated, or Full Lift to eliminate or test for ground-loop hum. Useful both as a permanent fix and as a troubleshooting aid to identify grounding faults.
Pros
- Passive — no external power needed
- Three grounding modes for flexible troubleshooting
- Sturdy metal housing and solid connectors
Cons
- XLR-only I/O — no RCA or 1/4" adapters included
- Limited to balanced XLR circuits
- May not solve noise from non-ground-loop causes
VerdictA simple, rugged tool for diagnosing and removing ground-loop hum in balanced XLR chains. Fully passive and easy to insert into a signal path, it gives three grounding options to help stop buzz without added power or complex wiring.

A pro-grade isolator when you need one
Built like pro audio gear: metal case, secure soldered joints, and rock-solid connections. Use it sparingly but confidently for any stereo or mono feed that needs grounding control.

Nathan R 5/5
Practical troubleshooting tool that performs
When moving cables and outlets don’t help, this unit makes isolating the problem easy. It’s compact, solid, and passive — plug it in and test. It won’t fix every noise source, but it reliably eliminates ground-loop hum when that’s the issue.

Ignacious R 5/5
Makes the hum disappear
A small but effective piece of kit — I used it with mixers and other stage gear and the annoying buzz vanished after switching the ground lift. Connections feel robust and there’s no extra power to manage.

Reviewer Manure 5/5
Quick cure for persistent ground buzz
Ground-loop hum can waste hours of troubleshooting. This inline XLR isolator gives three ground settings — standard, semi-isolated, and full lift — so you can both remove noise and determine if grounding is the culprit. Completely passive, no batteries or wall wart required.
