The A-133 has a manual offset control. If you e.g. turn this control to ~ +3
you can add an LFO signal with adjustable level to the CV input.

In general nearly all A-100 modules have an offset control for each voltage
controlled parameter. There are only a few exceptions like the low-cost dual
VCA A-132-1 or the dual crossfader A-134-2 with small 4 HP front panels
(only sockets, no controls).
