My us-122 is all messed up right now. It started with the left side just not working one day and i haven't been able to figure out how to fix it or where to fix it. Now on top of that everytime i plug my condenser into the right side and turn the phantom power on it makes a fuzzy hum noise that is like -5 db. really bad! if anyone knows how to fix either of these problems and help would be great.
