Okay so I've been using a shitty m-audio interface and just got a newer behringer xenix x1622 usb mixer for free so I decided to start using this. I've been watching videos on youtube about it and recording from it and for some reason I can't seem to record anything vocal wise. Logic picks up the signal but it's super low and when I try to record, nothing. Can anyone tell me what I'm doing wrong? I'm new to mixers so it's probably something so stupid but I can't figure it out.
