Do I need star grounding for my audio system?

Why do balanced Shields connect to audio signal ground?

  • Many audio manufacturers, consciously or unconsciously, connect balanced shields to audio signal ground; pin 1 for 3-pin (XLR-type) connectors, the sleeve on 1/4" (6.35mm) jacks. Any currents induced into the shield modulate the ground where the shield is terminated. This also modulates the signal referenced to that ground.

What is a star ground in a music room?

  • In the PS Audio Music Room we have multiple grounded AC receptacles on dedicated lines. That means that each AC receptacle has its own wires running back to the central breaker box where the main ground is also located. If each piece of gear is plugged into its own dedicated outlet, then you’ve formed a star ground.
