EARTH GROUNDED SOURCE EQUIPMENT
Source units with a 3-pin mains power cord will typically have the audio output ground connected to the earth-grounded
chassis. This can be verified with an ohmmeter by disconnecting the mains power cord from the AC outlet and checking for
continuity between the earth ground pin and the audio output ground. This test should be done with the equipment
installed in the complete system, including cables. If the audio output ground is connected to the earth ground pin, it is
earth grounded equipment.

FLOATED SOURCE EQUIPMENT
Source units with a 2-pin mains power cord have no means to connect the audio output ground to earth ground, so usually
the audio output ground is floated from earth ground. However, this does not insure that when installed in a system, the
audio output ground will remain floated from earth ground. The input cable to this equipment may already be connected to
earth ground earlier in the audio chain, and it will typically be carried straight through to the output. It is also possible that
the audio output ground connects to the earth ground through the chassis to an earth-grounded rack. The only way to know
for sure is to test the installed system. Use an ohmmeter to check for continuity between the earth ground socket of the
mains power receptacle and the audio output ground. If the audio output ground is not connected to earth ground, it is
floated equipment.
