Handholding 480s with relatively nice mogami 15' mic cables resulted in *many* audible handling noises for DGQ - most sounded like deep bass, almost similar to wind noise. This was indoor with no AC circulation, so it was actually handling noise. In listening after the fact, I recall points when I was shifting mics (that setup gets heavy after a while), and the noise is obvious. I learned to be much more careful after that outing. Food for thought.
