audio problem

I'm getting crazy because of many audio problems:

when I put my ch1 and ch2 input levels on 'line' I don't get audio, (neither with the help of a mixer, neither with a direct solution (sennheiser EW100 G3 with lavallier) when I put it on 'mic' I get a free scratch sound, which I hear trhough my headphones.

I have the feeling that the BMCC leaks power that causes this problem.

I have waisted loads of time and I am not getting anywere near a solution.

Am I the only one with this problem?

I had a similar problem like this yesterday. This is what I did.. I set the Line Audio to 100%, my headphones to 100% and the Mixer (where I was getting sound from) to just below 0db.. I got good audio, it was not as loud as I wanted but it was a clean signal.

Then after the shoot, I increased the volume with Final Cut Pro 7 and sent the audio to Soundtrack to add a compressor to it. I got very good sound like that, it wasn't the best but it was very good.

Double post. Locking this one, please continue the conversation here: viewtopic.php?f=2&t=7859
