I received my new Tascam DR100 Mark II from B&H yesterday.
I was immediately confronted with a slight, but ever present crackling/popping sound when I adjust the Record Levels (via the ganged knobs on the right side).
I was using a Sennheiser MKH-416 Mic with the Mic Gain on the back set to "H", however, I unplugged the mic and the record level knob continues to make this crackling/popping sound whenever I turn it.
Has anyone else encountered this problem or did I just receive a defective unit?
