you need a ground loop isolater. you can get it at the shack or you use to
be able to. It is a long transformer that kills the ground loop. All hook
ups are in the box.
A cheap solve is to kill the ground on the computer but I didn't want to do
that. You can do that by hooking up one of those cheater plugs and not
hooking up the ground on it.----- Original Message -----

Subject: feedback from internal hard drives
Hi list,
This is a characteristically longwinded message from yours truly. you've
been warned!!
I've noticed upon hooking up my behringer 31 band eq that if I raise up
the higher bands I'm getting the feedback of my internal hard drive's
motor and some power static. the connections are as follows.
a pair of male xlr connecting to two rca outputs on a sound blaster x-fi
pro external sound card.
Two standard xlr male to female cables connect from the eq to two
nearfield active studio monitors, adam audio a7x's.
The power is grounded on all three-pronged plugs. I have an internal
soundcard which is an m-audio delta 1010 lt. That's the audio side of
things, here comes the computer side of the equation.
a thermaltake atx mid-tower case holds an asus wd5 delux motherboard,
don't quote me on the exact name. The hard drives, there are 3, are all
sata 2 drives, 2 500 gb drives and a 1.5 tb drive. The two 500 gb drives
are a few years old, they make more noise than the 1.5 tb drive. The catch
is that one of them is my main drive for program files and the like, so I
don't want to put it in an enclosure. The other two could be taken out and
enclosed.
My main concern is editting, the feedback won't get through to the digital
transfers, but I'm not sure if I can deal with this high pitched noise,
it's a high b-flat. I'm wondering if anyone has run into this and what a
good solution might be?
