RANDOM SOUND BOARD QUESTION

What would rubbing alcohol spilled into a fader do, if anything? There
was some massive feedback during a show after this had occured and it
wasn't ever tracked down to anything. Maybe this had some effect?

I know..longshot at best.

What frequency was the feedback happening at?
I ask cause I once had a drink spill around the (top-oriented) connectors of
a desk which apparently caused a short in a channel using phantom power and
sending an almighty low-frequency roar through the system. It was the day I
realised why individual +48v is a cool feature.

I've also had a scotch'n'coke go down the crossfader of a DJ mixer which
brought in the "out" channel all of a sudden and remained that way until it
was replaced - no doubt due to the sticky goodness of the coke.

But I digress... Alchohol should evaporate rather quickly, especially when
warm. Are you still experiencing weirdness? Can you replicate the problem?

If you lose the ground connection to a fader, it has the effect of making
the fader fully up, possibly causing feedback if it controls a mic channel.
But it seems unlikely that a spillage of alcohol would do this.. Most
likely scenario is that you spilt the alcohol, it had no real effect, and
the feedback was caused by something totally unrelated.
