For operator safety all equipment should be referenced to a good mains earth.
Multiple earth paths cause earth loops resulting in audible hum.
If earth loops cause problems disconnect the signal cable shields at
destination
end. Mic cable shields should remain connected at both ends.
Ensure all equipment goes directly to the common earth star point.
Note: Some audio equipment comes with an earth lift to disconnect audio earth
(OV) from chassis earth. Refer to the User Manuals for that equipment. This is
often used in rack mount devices.
WARNING: Never remove earth connections without checking for continuity to
ground.
