When a ground loop occurs, the cable’s ground conductor (often the shield) ends up carrying both the audio ground and hum/noise caused by power flowing through the ground connection. Ground loops can be improved by using balanced connections, or, if that is not possible, by isolating the signal/power grounds between the devices. Below are a few things …
