    Hey. I Just set up my first daw.

    I have a Hercules Firwire interface. Im using a pair of Fostex monitors.

    When the Firewire cord from the interface touches the metal around the input on my laptop its starts buzzing and does so when it is in all the way.

    It sounds like the buzzing is directly connected to what the computer is doing. For example, When i open up lets say cubase or any other progam the buzzing would get more intense or change in some way.

    How can i fix this?.. Thanks.

    It sounds like you have some type of ground loop problem between your computer and interface with your monitor amplifier and speakers? You may want to try and lift the ground on the AC cord to your interface unit or the amplifier? BUT BEWARE OF SHOCK HAZARD! To eliminate ground loops one must usually lift or disconnect a ground wire that is causing multiple paths to ground. If your interface, amplifier or PC don't have a grounded AC plug (3 connectors), just try flipping it in the outlet upside down, unless it has a larger phased electrode which cannot be inverted?

    MUCH more info needed.

    But.... check your power outlets, it's amazing how many can be wired backwards... even in brand new homes. Get a continuity tester from Home Depot (5-10 bucks), don't be 'inserting' plugs in backwards like Remy suggested, also, don't be disconnecting grounds unless you know what you are doing!! Yeah, OUCH; now i'm DEAD !*!!^#$@!!

    Anyway... is Remy a guy or a girl... all I know is, foam ain't no morning after pill..............

    Do you know the implications of the salutation "Ms."?
    Not to mention, what guy has a middle name of "Ann"?

    I tried turning the plug upside down with no luck. I plugged another surge protector into the outlet and mixed up the plugs and finally got results.

    I put the two plugs from both of the monitors on a seperate surge from the same outlet and all the buzzing went away.

    Thanks alot RemyRAD.

    hi I think if I lived over there I'd buy a 1000va mains isolator tranny and run all my audio kit off that. It is a wonder there are so many of you left! You cannot be so cavelier with 230volts.
    Nice to see your still kicking Remmy, ignore the creeps.

    bye bye be safe
