Cgs synth

I never connect my signal ground directly to mains ground. I always put a 1k
1 watt resistor between the two. This helps prevent ground/hum loops. That
also means that my panels cannot be mounted hard to a metal case that is
grounded to mains earth. I solve that by having my power supplies in their
own metal cases which are earthed to mains earth. The resistor between 0V
and mains earth is then installed in the power supply. If the power supply
needs to go into the same case as the rest of the synth, the power supply's
own smaller cabinet is mounted using some sort of insulators, such as small
rubber shock mounts, and the 0V connection is connected to the panel/case
earth.

side , is that correct ?
