Hi, direct connection of audio ground to Safety Earth can give rise to a grounding loop causing hum. Connect the safety Earth to the audio ground through a disconnecting network to break that loop. But is it safe? The main purpose of the Safety Earth is to ensure the chassis and any exposed...

Figure 1 show conventional audio device plugged on main sector. Phase conductor transports main tension (220V 50Hz / 120V 60Hz) and current. Neutral conductor is normal return line current. Safety earth ground (not used on this sample) returns abnormal current to earth. Safety earth ground and neutral were link before security circuit breaker.

The safety ground wire in the cable is connected to each chassis at its system star ground, thereby extending the safety ground function to the second chassis. Be careful of the routing of the safety ground wire that connects the two chassis – it should take as direct a route as possible and lie close to the chassis.

If you are planning on adding more advanced Earth grounding to improve the performance of your audio system, it would be a good idea to make sure the electrician installing your Earth grounding systems isolates your building's lightning ground, your building’s main Earth ground, and your dedicated audio ground from one another. First things first.
