I wonder if it could've been a poor connection or plug, cable, outlet box at the power source.  Loose plug, poor connection in wall socket, something that caused you to lose juice just based on positioning of cord, or plug, maybe a dirty main pot or fader position, was there poppin too ?  That could be ground... Did you notice if your pilot lights also cut in and out on your amp/mixer when this happened, this would of course mean a connection at the power source, or perhaps ground problem causing amp to go into protection mode ?  Can you determine if it was an intermittent cutting out at a power source ?  


I've had dirty contact points in potentiometers, cause crackling cutting out that I thought was a bad jack, or cable.   This has happened to a few guitars of mine,  and although I thought it was my cable or a bad jack (into the guitar or amp, and I was about to replace the 1/4 inch jack on the guitar), the tech told me, that wasn't likely the problem,  he had to open the guitar and spray the potentiometers with chemtronics tuner degreaser, to clean the contacts which were causing total cutting out, and cracking... dirty pots, or contact points, sliders, etc...

This a weird one and I just love a puzzle.  You say it doesn't affect the music just the mics.  What sort of mixer amp do you have?  How is the music connected?  
Tape-in through RCA jacks or into chanels via quarter inch or XLR?  Does the problem occur even if the amp has been on for 20 minutes before you start?

If the problem is JUST on the vocals ..try another  channel - If your like me I hook my mics up in the same 3 channels week after week- maybe they are worn ?

Do you run your monitor in such a way that it would cause a short to your mains though ?    Assuming the monitor was the problem ?  How would the monitor cutting out affect your mains ?   I guess this depends on how you wire these things...

Was there any popping ?  Pop and cutout ?  That could be a sign of grounding problems.  Certain amps will go into protection mode if there are significant ground probs... or there's an overload.  Not sure how you wire your setup..   Have you checked your jacks and speaker cables for bad solder points ?

This is kinda out in left field but it fits.  If you're using the dynamic mics make sure the phantom power is off.  Next, there is a button on the amp that kills chanels 1-6.  With the amp off click that a bunch of times to clear the contacts.  Turn it back on and see if that cleared things up.

Could be the built in compressor is taking time to warm up, before it functions properly......just a thought.......

My 5016 does 15 minutes of stretching, and a couple of laps around the block before it starts a gig......

It seems when you hit the break button the speakers make a pop sound. After clicking the break button on and off a bunch the problem with the speakers didn't happen.

Babs I firget what it looks like on 808 but if its like mine the knob is rectangular.  With a regular pair of pliers carefully pull the knob off. Then take a big straw and place it over the switch arm and tight against the switch then blow on it inshort hard blasts Then spray with tuner cleaner or contact cleaner Then do the straw trick again. Replace the knob Chances are that will do it
