Reply to Traktor Volume Question

So my last show was about 2 weeks ago... I am still pretty new to the whole djing thing, but I had a question concerning volume in Traktor...

I am going to try and explain this the best I can, so bare with me :/

My Traktor layout is pretty much

Limiter -3db
Master gain -10db
Deck Gain 0db each

My last show, the mix was actually kind of low, so I tried turning up the master gain my self, the volume jumped, and for a moment, I kind of screwed up my own set... I still feel kind of bad about it...

My next show is pretty soon, so I was wondering, what you guys run for volume settings in Traktor... Also, do you believe it would of been wise, for me to tell the PA people, to turn up the master out? The monitors at the show were really low also, so I brought 1 studio monitor, as a dedicated, and that helped a lot...

Hope to hear some feedback, thanks!
