Hello,
My understanding of this module is that it only outputs fixed voltages from each of the 16 channels based on the position of the corresponding slider and the mode that it's respective switch is in. It is meant to be used as an ergonomic/hands-on/easily-accessible/performance controller of other modules.
It does not process external voltages. Based on what you've posted, I believe that's what you are asking about. It does not work like an attenuator/attenuverter, VCA, or mixer. You could, however, use this module's voltages to control a VCA level or channel levels in a voltage controllable mixer, for example.
I hope that info is helpful and answers your questions!
