    Dear all,

    I am just setting my recording studio, I hope you can help me and accept my very basic questions.
    My devices consist in:
    AKG 414 LTD mic;
    SPL Channel One preamp;
    Fireface 400 UCX;
    MacBook Pro.

    The mic is connected to the pre-amp through a XLR cable. From the output of the pre-amp a balanced cable goes to an analog input of the Fireface.
    Now I am trying to record, with the Phantom switched on, and what I see is that if I increase (after 30 dB) the mic-gain in the Channel One I start hearing a quite strong low frequency disturb. I need to increase the gain because otherwise the signal is very weak.
    With this interference the quality of the recording would be unacceptable
    May you shine a light on what is happening?
    It would be great.

    Thanks!

    Giuseppe

    You probably have some sort of ground issue - Try changing everything in the chain out, one piece at a time.

    But yeah, this has about as much to do with mastering as ---- well, as much as a ground hum in a tracking chain would have to do with mastering.

    Make sure you're going from line out to line in and not into the mic in. You never know.
