I think I may have discovered a way to get clean sound out of this microphone preamp. After doing a little research, I learned that after successfully hooking up the preamp into the audio interface, you need to learn something called, “gain staging”. I’ve been doing some reading on that. There is no ground loop issue through the preamp, it has something to do with “gain staging”. Fooling around with the controls and knobs. For example, I think I would need the gain turned all the way down on the mic pre. Then you would have to mess around with your volume controls on your recording software. Something like that. Gonna be researching “gain staging” today. I think I’m still able to get clean microphone sound, just gotta figure out the gain staging stuff. I’ll work on it.
