Hey forum! I just got a new mixer: DOD 820 RM Mixer. When I say new, I mean "new"...I bought it used. It DOES work. I know this because the light is on, and the phantom power light and everything is on, but I can't seem to figure out how to work it...when I plug in a mic, no lights go on, even when I move the corresponding knobs. I have it connected to my computer, but it won't record in Audacity. Any help?? Thanks alot!
