In the A-100 system the attenuators are located at the inputs of the modules
but not at the outputs as this principle is much easier from our point of
view than having the attenuators at the outputs. Most modules have this
input structure for control voltages:

one manual control or offset (e.g. manual filter frequency control)
at least one CV input with attenuator

With the manual control you adjust the offset of the parameter in question
(e.g. VCF filter frequency, VCA loudness, VCO pitch), with the CV attenuator
you adjust the amount of the effect of the external CV, e.g. how much a
triangle output of an LFO modulates the filter frequency.

I hope everything is a bit more clear now.
