Anyone tried doing four-channel audio recording on the HVX and getting all the channels at proper level? I have been shooting with the two on-camera channels as backup on channels 3-4, a long shotgun on channel 1 and a Lectronics lavalier on channel 2. I may be missing something in the documentation, but I can only get levels set on whatever is on channels 1-2. Any suggestions to get all four balanced?

Sorry about the double post. I got an error message when I submitted the first post and didn't think it went through.
