Noise on the Firewire - where do I start?

Discussion in 'Recording Gear and Equipment [BG]' started by LowDown Hal, Sep 4, 2008.


  1. I recently purchased my first mixer / recording device. It's an Alesis Multimix8 Firewire.

    Everything seems fine from the mixer point of view.

    As soon as I plug in the computer, via the firewire interface, I notice noise coming from the monitors.

    Any clues, suggestions, ??

    THANKS

    If its a "Crackel" type of sound try inceasing the buffer size in the software.

    Ballanced speaker cables?
     
  4. I will give that a try. Thanks,

    However, just to be clear the noise happens as soon as I connect everything. It seems buffer size would only matter when recording and/or playing back?
     
  5. It's probably a ground loop.

    Try plugging the speakers or the mixer into different outlets and power bars.
     
  6. Well, major progress. Root of the issue is identified just needs a solution now :)

    It seem to be a laptop power supply induced noise.
    It goes away when I run off of battery.

    Everything is plugged into the same power strip which is properly grounded etc. I assume the AC/DC converter power pack is dropping the ground reference somehow.

    Since my current laptop is using a PCMCIA Firewire adapter I'm wondering if there is a BIOS setting for PCMCIA Slot Power?

    ???????????

    Is your laptop an Acer?
     
  8. Im having this exact same problem with a saffire unit and my Imac. Weird....
     

  9. Nope, it's a Dell Precision M70.
    Next week I'm getting an HP. Hopefully that will be better, but I want to figure this out.............
     
  10. Finally got the new HP laptop. Installed everything and still have the same problem.
    Cr@p!!!

    I has high hopes since this one even has the little noise suppressor barrel clamped on the power cord.

    Anyone ever figure out a solution to this problem?
