KRK V6 = computer noise? G5

    this may sound strange but, i just bought krk v6 monitors and replaced my old monitors BUT once i turned them on i hear a faint digital noise being produced which seems to come from my G5 running through my audio card.

    Example:
    When i load programs up i can hear the compuer through the monitors. Digital pulse, faint static and or squeeling sounds from the hard drive.

    i do not believe it's my audio card cause the speakers that i had on it just before do not produce such sounds. Does this sound familiar to anyone?

    Did i get a bum pair of KRKs? Is this a problem on my end or do I need to return them for a new pair?

    your probably hearing the higher definition of the krk's as opposed to your old speakers. If those krk's have higher dynamic reproduction then viola....youve stepped it up.

    Agreed...your new monitors will show the good and the bad. But you want to hear the bad, so you can fix it!

    thanks i think...lol

    so any ideas how to resolve this?
    the only way it dissapears is if my G5 is turned off... or if i turn off my audio card...

    neither sounds like a solution :/

    ideas anyone?

    the only thing i can think of is that im running my audio card as such:
    maudio firewire rca out to rca adapter to a 1/4" / xlr cable...

    problem is, that's the only outs my firewire card has...

    the krks are definitely better, i had first generation maudio monitors :(

    If you're running an RCA out that means you are going unbalanced....this could be the problem.

    i have also tried plugging my g5 and audio card power into one outlet and the krk's into another and i still hear the computer somehow...

    the audio cables are not even crossing any electrical cables that i can see?

    great...lol

    the only thing i can think of now is taking out my MIA card from my PC and dropping it into my G5 and run the 1/4" outs...

    but, that MIA card is only 20bit i believe :(

    actually the mia is 24/96k... will this be better than running my firewire card? will this increase latency though?

    ok... so the mia's pci slots don't align with the G5's pci slots :(

    i guess this means i need to trade in my firewire card and get a new pci audio card with balanced outs?

    That may work better, but what you have should work. I would try moving your firewire card around in your CPU tower. Or do Macs have them integrated somehow? Try a slot farther from your processor/harddrives. I use a SB Audigy for Windows sounds and there is an internal headphone out extension thingy that hooks to the headphone jack on the front of my CPU case. The normal audio outs on the card don't have the noise you describe, but the headphone jack on the front does. I'm guessing it has something to do with the wires connecting the jack and shielding or something to do with being closer to the Hard Drive and picking up more interference.

    I had buzzing in my new monitors that I never heard in my old ones. turns out it was ground looping.

    damn... thanks guys...

    as for my firewire card, it's actually a box that is connected via a firewire cable...

    the guy at guitar center said i should turn the trim on my krks down (they come default at +6) and maybe turninging it down to 0 or whatever may resolve his problem... but that just doesn't sound right...

    i am very confused...

    it's def not a ground problem because i actually don't get hum or buzz, i actually hear the computer working... eeks

    Right, I understand that your soundcard is external and hooked up to the computer by a cable. But how is that cable connected to the computer? It looks like G5s use some kind of integrated firewire ports so moving that around is probably impossible. Are you plugging into one of the front firewire ports? If so, try connecting your soundcard to the one in the rear. Those front ones are probably right under your hard drive. Fine for data or video transfer, but this could be interfering with your audio signal. Or if you can get an extra PCI firewire port card (usually pretty cheap) you could try that out to eliminate the possibility. Or maybe I'm full of crap.

    Thanks Reggie. This makes some sense now. I appreciate it.

    I would also like to share with all of you some info I received from Maudio (sounds card) and KRK (speakers):

    1 - Maudio said to make sure the audiophile is only being powered by the firewire 400 port

    2 - KRK said to put a 3-2 prong adapter on the KRK plugs to remove the ground from the speaker. He said the 3 prongs are designed for European use and our systems are dirtier here and this ground prong usually introduces feedback and loops.

    3 - KRK also suggested bringing the trim down from +6 to something more comfortable, possibly "12' o'clock", this will introduce less noise and background interference.

    I will try everyone's feedback and see what happens, Thank you all so much.

    First of all, there's nothing wrong with your speakers.

    This is normal.

    You're hearing things you just didn't hear before because of increased resolution. You're hearing the mouse move and other crap like that. Not hiss or ground loop issues.

    Personally, I've not found a way to get rid of the sounds you're talking about but they only occur when the mouse is executing commands or moving.

    These sounds do not actually get recorded, so you have no worries there.

    I have learned just to live with it and ignore it as it has no bearing whatsoever on the recording or mixing process.

    Thanks for all the help guys...

    This is what i have figured out with some help from KRK tech support... you may not believe this, but:

    Go and buy a 3 o 2 prong adapter and plug the speakers into them.

    Resolved my issues. no G5 noise anymore. All gone. All I hear now is some minor quiet ground buzz. Nothing major but at least i can trouble shoot this one. lol

    so once again, if anyone has this problem that i had - "hearing" your computer through your speakers, go to radio shack or home depot and spend $2 and get the 3 to 2 prong adapter to remove the ground prong :)
