I was wondering if there is a specific way to connect my Stadium to my Apollo X4. I understand that the Stadium in and of itself can be used as an interface, but i like the way my Apollo works with all of my other stuff. I know it needs to run line level, but when I connect via XLR, I can only get sound at Mic Level. Is there something I'm missing. I'm not the most tech savvy guy and have used tube amps my whole life so this is quite new to me...
