| Modules A-130 and A-131 provide voltage-controlled amplification. For
audio signals, you would normally use the exponential VCA (A-131), and
for control voltages, the linear VCA (A-130). It doesn't always have to
be that way, though.
The amount of amplification the VCAs provide is determined by the
voltage at the CV input, and the position of the gain control, which
sets the overall gain in the system.
The VCA has two audio inputs, each with an attenuator. They are
amplified by an amount determined by the combination of the gain and
the two CV controls.
