Question

I am trying to figure out how best to boost my MXL 990 to line level without background noise but cannot figure out how to adjust the x-max preamps without background hum (of which there is a lot even in the quietest room in my house). I am wondering if there is some preamp setting I am missing (because I am not using the Universal Control). I am just using Studio One 3.

You might need to troubleshoot for "ground loop hum".
