    H4N , Zoom digital mic recorder , crackling ,advice please

    Hi All

    These seem to be quite popular , but first time i'm attempting to repair one .

    Customer mentioned a crackling coming through when using an external mic to record via XLR ports .

    What i have experienced is the unit being tap sensitive & crackling even without playback .

    Anyone have experience of working on these units ?
