Chord Ground Loop Isolator | 3.5mm Jack to 3.5mm Socket | 600mm Cable

Eliminate Earth Hum from Your Audio System

Ground loop hum is one of the most frustrating problems in audio — a persistent low-frequency buzz caused by differing earth potentials between connected equipment. This Chord ground loop isolator solves the problem cleanly and simply, breaking the ground connection between two devices to stop the hum at its source without affecting your audio signal.

Fitted with a 3.5mm jack plug input and 3.5mm jack socket output, it connects inline between any two pieces of audio equipment sharing a 3.5mm connection — ideal for linking a phone, laptop, or media player to a mixer, amplifier, or car stereo. The 600mm cable gives you enough reach to route neatly in most setups.

Compact, passive, and requiring no power, this isolator is an essential troubleshooting tool for home studios, live rigs, and everyday audio systems. Sold individually.
