Thanks for you help,
I didn’t mix the the channels of my camera while I was shooting but the channel from the sound desk was the main out and the soundman played some music under the voice. I used a wireless mic to record the sound desk channel and it was a small simple sound desk so the soundman couldn’t split the out for me.
So now in post I have one channel my external mic that the sound on it is ok but changing because I was moving and second channel with the speakers voice and music background. Each speaker talked for 10 min and I’m making a 2 min for each but the music at the background sound bad.
Thanks
Oren
