Default Chassis ground

In my 4-channel GC I am about to ground to chassis with a 100R and a 0,22uF.
Should each channel be grounded to cases with each set of 100R and 0,22uF or should they share one set only at the same chassis ground point?

..the ground wire from each channel comes from star ground.

Try the ground connection with no RC network first, you may not need it and it reduces safety. In my stereo GCs, I usually connect both amp grounds together and run them to the input connectors and connect to chassis ground there. This is one method of reducing ground loops.

My GC doesn't have AC ground, cause AC ground is normally not used in households my country, except for computer installations etc.
So does safety become an issue here then...?

Default RC network

By the way. What is the function of an RC Network? What does it do?

RC = Resistor/Capacitor or Zobel Neetwork.

transfer hi frequencies oscilatons to ground and stop chip overheating

You find value you required on many website
