hello keld,

afaik the modules a120, a121, a122 and a123
can't be overdriven with standard a100 signals.
they haven't changed the design of these modules,
but they designed all the later filters in a way
that the inputs can be overdriven.

the a124 seems to have a bit more gain than the a122,
but not as much as the a108 for example. i never had
a problem with low gain on the a124, so it seems to
be alright here.

from my point of view the a120 would benefit the most
from changing the input sensitivity.

best wishes

ingo
