Separate and identify "clean" and "dirty" AC outlets. Use clean outlets for audio
equipment and the dirty ones for lighting, air conditioning, cola machines etc.
Do not intermix these two types of outlets. AC interference can be greatly
reduced by using an isolation transformer or some type of balanced ac power
device to power outlets. Ground this transformer directly to the "central star
point".
After all equipment is connected to the ac power, check with a ohm meter or
continuity tester to be sure of no possible chance of ground loops.
All equipment should be physically located as far as possible from the main
breaker panel and should be totally isolated from the equipment rack and other
equipment so ground loops are avoided. Equipment can be mounted in wood
rack rails to avoid ground loops or you can use "HUMFREES"
Now you can run a #12 stranded wire with jacket from each piece of equipment
to the "central star ground point". All ground wires should be the same length
with a tolerance of plus or minus 10% in order to have the same ground
potential everywhere. On the equipment ends of each ground wire you should
solder a round hole screw terminal.
Remove a chassis screw from each piece of equipment and file the paint in that
area so it will make good contact when you connect the terminal. Next, connect
the ground wire terminal to each piece of equipment and connect each wire at
the other ends to the "central star ground point".
