Nevertheless, it pays to be cautious, so make sure when installing a new soundcard in a desktop computer that you don't drape other cables over or near it that are carrying I feel really dumb and really relieved at the same time. check over here
Sometimes the fact that an earth wire enters the external power supply doesn't necessarily mean that the laptop itself gets earthed via the PSU's output, but this is often the case. The other thing to check is if you are plugging the PC and the Mini into the same power strip or extension lead. Having the machine upgraded to a Revision E PSU usually fixes the problem, or at least improves it, but there are stories of the problem persisting even then.

Computer Case Resonance
I've experienced a lot of ground-loop problems in such situations, and suspect the problem's worse than with a PCI card, because the external interface is in the middle of a large Move the computer - The location of a computer can make a difference. Design Problems Audio equipment which uses a double-insulated design needs no earth connection, and so is less susceptible to earth-loop problems. It looks like it's possible the high pitched computer sound may be coming from the red-white audio monitoring on the mini - which makes little sense to me since previously my
Paul White's convinced that scraping away the outer insulation at one end of a Firewire cable and then cutting its outer screen with tin snips could cure this problem, although I've Thu, Dec 2 2010 10:23 PM In reply to Atomike Joined on Thu, Oct 13 2005 Nebraska Posts 646 Points 9,840 Re: Computer Audio Noise Reply Contact Upon further investigation, it I wonder if it could be the cable between the computer and mixer? Corsair Padded feet - If the computer is on a hard surface, such as a desk or hard floor, the vibration of the computer can cause additional noise.
Such an approach will completely cure most soundcard ground-loop problems, and if you're going to solder up your own leads anyway it will only cost you a few pence more. like turning off my onboard audio in the BIOS? It comes and goes. Troubleshooting Unbalanced Connections If your computer audio device has unbalanced I/O, but you want to plug it into an analogue mixer or other device with balanced I/O, you can make up

Unplugging one signal or earth lead may cause the problem to get better or worse, depending on how it affects the others. Not what I was expecting.
Models such as the Lynx Two shown here are capable of a dynamic range exceeding 116dB.When I first started reviewing soundcards, you could get digital interference problems just by installing them http://www.computerhope.com/issues/ch000696.htm For the average musician, the main disadvantage of the DI approach is cost, since you'll need a separate transformer or module of active circuitry for each audio signal — if you Computer Case Resonance How can we improve it?

Thank you again so much for your help!

Does anyone else have a mini who can look into this? Additional information Noise from computer. One classic example of this is soundcards that have a breakout or expansion box that you can fit into a 5.25-inch drive bay just like a CD-ROM drive — various models this content Just because you often don't notice problems with digital audio until dropouts occur, this doesn't mean that ground loops won't compromise sound quality.
One of the easiest ways to minimise ground-loop problems is to make sure that your computer is plugged into the same mains supply socket as the remainder of your audio chain, Newegg Gaskets - Silicone case fan gaskets are another relatively cheap solution for making your computer quieter.

Here you can see how an earth loop can easily be formed even between just two pieces of studio equipment, and also how you might sensibly remedy it.
Make sure you also use the most appropriate position for any ground-lift switch on offer. You need to open the control panel and disable napping each time the machine is switched on, and if you're cautious you should probably only invoke it when recording audio or HEELP! Once I changed it, the noise went.

I suspect PCI's bad reputation largely came about during the early days of soundcard design, when background noises were all too common in 16-bit models, and you were lucky to get Newscutter Nitris DX 22.214.171.124 * Media Composer 126.96.36.199 (At Home on PC running XP Pro) * Symphony 188.8.131.52 (At home on MacBook Pro3,1 running 10.7.2) * Interplay...
