Im using my audiobox 1818vsl to record drums, guitar, and vocals. The recording software I use is reaper but regardless of what I do, there's always a ridiculous amount of static in the background. I've tried turning it off and on multiple times, fiddling around with the mics, used different mics, used different softwares, but nothing can get rid of it. Sometimes if I'm lucky, after a while of fiddling around the static goes away. But it always comes back once I turn the interface off and back on again.
I have a macbooc pro 13", OSX Yosemite, Version 10.10.5, if that makes any difference.
Please help me!
