Kontrol Z2 sound volume settings for powered speakers

I would really appreciate if someone with more experience could give me advise on how to adjust Z2 sound volume settigns to play with the powered speakers. I watched few online videos and even more confused. I presume output Master volume (knob located on the upper right, just above booth knob) should be in middle (12) position, gain for both channels should be also in middle (12) position?
Questions I have:
1. when settings are as described above, master led indicator is in blue (which is fine), but led indicators for channels A and B are often in red. Is that OK?
2. Powered speakers will be set to middle (12) position and away from me so I cannot change that settings while playing the set. To control overall sound volume I should use Master volume only?
3. is it better to use autogain?

thanks!

 

There's probably an infinite number of ways to do this.

1) Not ok. Maybe use autogain from (3) and ensure you don't go into red.

2) Yes. At some point at the beginning of your setup, take a minute to soundcheck to ensure you know what your mx volume will be, and then use the Master Volume to control appropriate volume levels.

 

Thanks for reply.

I did some net research and this video has good points if anyone else is interested to learn more:
