Slightly confusing issue (to me at least!) regarding audio and a cable change. I would really appreciate any help on the cause of the following problem and any offers of how to fix in FCP.

Test 1 has the problem and test 2 is fine.

I was surfing the forum and saw Cucco touch on some phase issues with recording drums, I am fairly new to recording(2 years) and havent really learned to much about phase problems when recording drums or anything for that matter. I'm interested about how to acknowledge phase problems when they are there and how to fix them.
