So i was setup in the cafe at my school and I was in a middle of a song, and all of a sudden my music went really statticy and was distorted, also i have a problem with my volume faders, when i cue a song and the fader is not at 100 percent, the song blast at 100 until i move the fader then it reajusts....

I hope these aren't noob questions, I'll keep searching for answers in the meantime.
