It’s all in the manual. You should really study it to avoid future misconceptions about inner workings of this mixer.
True and not just about this post but in general.
And I’ll add that having a good solid grasp of the routing and signal flow on an analog board and associated outboard equipment first helps in visualizing the routing of a digital board and everything else that a digital board can do.
At some installs I’ve done when it comes time for the training if there was an analog mixer inplace prior I’ll have it close by so I can show them the function on the analog
board and then where that function is on the digital board.
