Question about Main outputs of the KPA, as well as a Volume question?

    After playing 2 Mackie HD 1521's in stereo today at my local music store, I am totally convinced 100 percent that FRFR is the way to go. It was absolutely fantastic, incredible to say the least. However, of course i had to use the 2 XLR outs of the KPA for this to work. My question is, if I want to run 2 mackie HD PA's as my live monitor rig, and use the other 2 main outputs to go to the FOH, is this possible? Is it possible to use all 4 ouputs at once? Sorry for the newb question, I just wanted to make sure.



    Also, volume knob questions: Is the "master volume" knob the same as the Main output volume under the output menu? The reason why I ask is, when I was under the output menu messing with my main output EQ settings, I turned the "master volume" knob, and the main ouput volume LED lit up and was turning while turning the master volume knob, thought this was strange. Thanks guys.

    Well you can use the monitor out to one of the Mackie's then use the Thru on the monitor to supply the 2nd mackie, freeing up both Main L/R for FOH - this is the better way that way you can control your direct monitoring easier/better, and the FOH can be set differently too. - of course its whatever works for you the best. so you have choice and thats a good thing! YAY!
    But if you want to use stereo, then yes you can use both sets of outputs at once.
