Okay, so this mic has 2 switches on the back. One is the pad switch. It has -10 and +10. What does it do to my vocals if I have it on -10 and what will it do if its on +10? The other switch has a straight line and a slanted line that goes into a straight line. What will it do to my vocals if its on the straight line and what will it do if its on the slanted one? You can see the switches here http://i.seimg.net/images/889562/main/at4040.jpg
