I plugged in my DM 3200 after almost 7 years in my garage. For the first 45 minutes after I connected it to my MOTU 2408, to my Mac via USB and playing a few tracks in Logic, I heard a popping sound and all hell broke loose. All faders started moving up and down, all STATUS LEDs flickering an a constant intermittent popping sound like a machine gun. I reset to factory, did all diagnostic checks, and the thing that didn’t pass was the clock settings. I can still move the faders with DAW control, but can’t get passed that state. Is it a board issue ? I can upload a video if it helps. please help, anybody.
