Only use balanced audio connections between several devices with their own power supply and grounding. If you are using decent equipment, chances are that they already have balanced line input/outputs with TRS 1/4" connectors (quarter inch jacks in tip-ring-shield configuration).

Some USB devices expect to be able to function at 480 MBps, but an audio ...
