S2 mic engage broken? Any ideas?

Pretty simple. Used to work no problem. Simply will not let audio throught. You can vaguely hear mic noises when you power up the unit, but then back to silence.

Bought used, not going to try to messing with NI, guess I'll just be plugging/unplugging from one of my powered speakers if I need to use a mic. Not terrible, cuz I hate using it anyhow, but the manager at my gig last night said I'd need one. :/

Found the problem! Opened unit and found a loose pin on the 10 pin connector near the button. I can hold my finger on it and it works.

Now to solder this back on there :/
