I have a graduation ceremony to film tomorrow night. The sound tech helped me hook up my Sony DSR-PDX10 to the sound board. We ran an XLR to inputs 1 and 2 (two mic cords) and an S-Video out to their jumbotron type screen. He left to go produce a video, so he’s unavailable.
When testing the sound through headphones, there is a constant buzz. I’ve tried connecting the XLR cord straight to the XLR adapter on my camera, where they had two cords joined together to make a longer cord. Still had buzzing noise. The noise is still there when I tried to run everything off of the battery instead of plugging it in. I can hear the voices from the mics on stage, but it just has that constant hum or buzz. This is not the case when I just use the directional shotgun mic that came with the camera (only when I plug it into a sound board). Any suggestions of what I can try, would be greatly appreciated.
