It seems I've got a smilar problem as one mentioned in topic July 18.
I use 2 jack cables from Monitor out and Direct out to 2 jack inputs on a mixer. Then I connect 2 QSC 1000 W. K8 speaker cabs to the L+R outputs on the mixer both with XLR cables. All for monitor reasons. Main outs go to large mixer.
With this connections my guitar volume drops significantly. Raising the potmeters on the mixer doesn't help. Raising more gain on mixer results quickly in red blinking leds. Raising Output on the Profiler seems to me not a good idea. Raising my volume pedal from minimum to max (for soloing) has also no effect. Volume stays at a certain (low) level on stage.
Someone with an idea?
