Hey I'm filming a seminar as we speak, the second audio channel isn't working. I'm shooting on my hvx200a in 480/24pa. I'm picking the speaker up on a lav, but the boom mic, in the second channel isn't working. When i plug the boom into channel one, it works. How do I get the second channel to work? I have channel two switched to Input 2 not internal. Please let me know!
