When I started my studeo I always had and still have terible grounding
issues. We even changed out our fuse box thinkint that might help
because we had a very old one. Anyway, nothing helped until I got a
power conditioner. Now I have clean power running to everything and no
noise at all. I will say that you need to buy a power conditioner
first thing. I paid around 200 for mine and it has 8 inputs. This will
give you clean power to everything and save you the headache of
dealing with the power company and things like that. You could try
that rout but you may try for weeks and not have any luck changing a
thing. I can't tell you a power conditioner is what you need to many
times. It was the best $200 I have ever spent and I could kick myself
for not getting one years ago. So go out and buy one right now. Should
I say it again? Now! Now! Right now. Hahaha ok I am done

Grounding for a building depends on the terrain and what type of ground
required for that terrain. Dry sandy terrain would probably require a
chemically treated area where one or more metal rods are implanted. In this
situation tapping onto a metal pipe might create a ground loop that could be
dangerously harmful to both electrical equipment and people.
The point is do a little research with the equip manufacturer but first call
the electric power company for grounding conditions in your specific
location. Grounding conditions can change across a neighborhood. So be
ware.
Don't reinvent the wheel. Make a few phone calls to find out where you
stand. After getting an understanding of where you stand with the power
company and equipment manufacturer, better decisions can be made. And after
calls are made and you have access to a maintenance man or electrician talk
to them before trying to reinvent the wheel or spending money.
The simple advice would be not to tackle ground loops without understanding
your specific situation. Experts are available at low or no cost.
Be safe!
Hope this helps.
Andre, electrical engineer

Oh,
I wasn't suggesting hacking anything or re-inventing ground. Only simple
thoughts like a wire at an unconnected ground screw on a power conditioner
for example. Sorry for any confusion...

get rid of ground, or use something as ground that shouldn't be. That
could damage your equipment before you even turn it on or cause other
problems like EMI.
Becareful with ground lifting, which just gets rid of the ground. If
you know what you're doing, or are working with somebody who does, you
should be able to get great results without resorting to crazy hacks
that can only damage equipment or kill you!
But it all does start with a good, well thought out wiring scheme.
Also, consider all the equipment you have in the chain, and I mean all
of it, from the smallest to the greatest.

Yup,
Well, on a budget is going to be tough.
When I first built my studio up, 60 cycle drove me nuts.
My advice is experiment.
For example,
* try to avoid running audio cables along side ac power in parallel.
* Stay balance audio everywhere if you can afford it.
* Experiment with ground wires from power conditioners or outlet
strips to real ground like water pipes etc. You'll need to do this
with headphones on and with nothing except white noise in them.
This approach ought to keep you busy for like weeks.
It's all about eliminating ground loops.
And after all that, you might be lucky enough to reduce your noise
maby 20 to 30 percent.
Unless you are willing to dig in with a bunch of money and as DJX said
an expert, you may have to work around noise as well as incorporate a
good noise reduction plug-in to help.
There are a number of good ones like Cedar, Isotope etc.

you already stated you can't change, the building's electrical, you
would be better off consulting with someone who is experienced in
studio set up, and can help you work on your particular setup. V

Subject: [ddots-l] Power distribution on a budget
Hello all,
Can any of you recommend good publications I can read on the subject
of power distribution in the recording studio?
I'm not formally trained as an engineer and often find myself
perplexed and frustrated in my efforts to eliminate stray fields that
cause the dreaded 60Hz hum. Unfortunately though, I am not in the
position to change the building architecture, including redesigning
the house electrical system.
So, I'm hoping there is an affordable way to isolate the room I have
set up as a studio.
Warm regards,
Fran Franks
