Frequently Asked Questions About Ground Loop Isolators What is a ground-loop isolator?Ī ground-loop isolator is a handy tool used to remove electronic noise from an audio signal. If you need other stage and studio audio tools, see our range of DI boxes and peripheral audio equipment. Using electronically balanced signal cables over longer distances and keeping them well clear of any power cables, video cables or other signal-carrying cables also helps. The best way to avoid any ground-loop issues is to hook all of your audio equipment up to the same power group. Some isolators can treat both balanced and unbalanced audio signals, and some isolators will also come fitted with noise level controls. This effectively 'skips' any DC-related noise, leaving you with clean and hum-free sound.

Your average ground-loop isolator will have one or more channels with an input and output, where each channel is kitted out with a special transformer that transfers sound signals magnetically rather than electrically. Clean Up the Audio with a Ground Loop Isolator Thankfully, there are plenty of ground-loop solutions out there, so you can find the right tool for the job.
