I’m not harping or disputing what’s been written, but let me share what happened at a gig last night.  Played a show with a terrific house sound system.  Surrounded by massive QSC beasts.  I don’t know whathey had behind the great and powerful Oz curtain controlling our sounds, but it i had to turn the volume knob to 95% in order for the sound guy to work with a signal.  I had the MX, and two korgs. 

I followed all the above post suggestions and gained some boost, but this goes beyond pumping out a few extra db’s

I’m not an engineer like BM, but could someone recommend a hardware device that would boost the output?
Or is this a flaw in my MX. 

I suspect it’s not.  Our local music store has heard same concerns.  And that’s was this is...a concern and not a complaint.  Just looking for solution or workaround. 
Thanks
