CV 2
This attenuator affects the level of voltage control at
socket ". It controls the amount of effect the CV has
on amplification.
3
IN 1 • 4 IN 2
Attenuators 3 and 4 control the level of the signals
input into the VCA.
H
If the output signal distorts in an unwanted
way, turn down the input level, using control
3
and/or 4.

Out
This attenuator controls the total volume of the VCA’s
output.

!
CV 1 • " CV 2
Sockets ! and " are control voltage inputs, whose
voltages are combined. The effective range of the
VCA goes from 0 V (no amplification) to +5 V
(maximum amplification).
