Re: Serious noise issues
For a start, all shields should be taken to a central ground Star point, I know there are many manuf of BOB's and systems that say keep the commons separate and ungrounded, But I have always followed the opposite method where it is possible, and taken all power commons to the GND star point together with the service ground conductor.
I have not had any problems so far.
I had a long thread here by some one with the same issues and after following the above method, cured his problems, unfortunately posts over a year old cannot be found here with a search.
