Grounding and Shielding for your DIY Audio Projects
https://diyaudioprojects.com/Technical/Grounding-Shielding/
The signal ground's usual and primary function is to provide a return path for the audio. Likewise the power supply ground is the return path for the power used by the circuitry. The case ground I will cover a bit later. Remembering that anytime current flows through a conductor it will cause a voltage, let us see what happens if you mix the ...

The power supply ground/common lead is carried over to the audio chassis along with the supply voltage lead(s), and is then connected to the audio ground. In the audio chassis, connect the audio ground to the chassis, either directly or through a resistor and/or diode block and/or capacitor, per standard practice. ...

A star ground is a collection of grounds all meeting at the same point in a system. Most well designed audio equipment utilizes star grounding internally, but when you hook together products as a system, it’s best to try and utilize one ground point if possible. Dedicated AC lines form star grounds.

If the mixer grounding is not correctly done this path can be poor. The best method is: Ground the power supply metalwork to the a.c. ground with a standard 3 wire cable and plug. Isolate the audio ground. Connect the audio ground to the electrical ground with a small resistor and capacitor in parallel. The resistor can be 33 to 100 ohms.
