Okay so the title is a little melodramatic
I just wanted to stress the importance grounding to newbies, like myself.
I had wrapped up my Channel Strip a couple days back (2 Green Pres and a
Calrec EQ) and I thought all was well, a little noisy but by enlarge it
worked great. I did find some anomalies but what came as a shock is that the
grounding was being done through my 002R!!!! The pres would not function if
the Calrec was not plugged into the 002R, all I got was a LOUD hum that went
away if the Calrec was inserted into the 002R.
After I discovered this I went about researching ?star grounding? here on
the board and came up with various posts and guidelines.
In my case I joined all the Pin 1?s on the XLR Ins and Outs to my AC/Chassis
ground and also attached the ground from my PSU to the same point.
After powering up with my new grounding config everything worked flawlessly,
not a single hum, no mater how you config the pres and EQ. The Calrec no
longer distorts or buzzes, which it occasionally did in the past and it is
as quiet as a mouse!
So the moral of the story is evaluate your grounding scheme, and even though
it might work, it might work better. I have def noticed a considerable drop
in noise as well, I?m not sure technically why this happens, but it is def.
noticeable.
Cheers
