  4. I’ve got a HK Audio rig that was running off a Honda eu70is inverter generator and had no rumbles. My friend was running a pair of Jbl speakers off a standard generator and suffered a bad case of the dc rumbles.
    If you can borrow an invertor generator you may be able to do a little test.

    Ok so next question, Does the amp produce this noise when nothing except the speakers are connected, and the gains are set at normal operating level. (P.s. What amp is it?)

    They are behringer active speakers, the noise was present as soon as the speakers were powered up

    Ok cool, right. The (noisy) output of that generator, combined with the inability of the powersupply within the speaker to filter it, is causing noise to enter the amplifier stage. Nothing you can do about that really.
