    hello.
    i was recording my synthesizer SY 85 into Apogee trak2 through coaxial digital cable using Sony Sound forge apps.
    even though i didn't play SY 85, the noise floor level is changing
    why did it happen?
    the noise level was -69 dbfs, but suddenly it was changed to -79dbfs. then again it was -79dbfs
    i live in south korea. and my outlet don't have ground wire ..therefore, i only use two wire such as -,+ for powering up equipment and computer etc..
    is it because of ground wire?

    get a LONG! shiny metal tupe or pole. Hammer it down in the ground and connect a wire to it.

    There you go :D
    DIY grounding :p
