AMPLIFIER GAIN – This knob controls the VCA's gain and
(1)
final output volume at the OUT jack.
UNMOD GAIN – This knob controls the IN A signal gain
(2)
when the module is in UNMOD mode (as indicated by the
UNMOD button). UNMOD mode allows the module to be
used as a VCA when modulation is not required.
AMPLIFIER CONTROL MODE (EXP'L/LINEAR) –
(3)
This sliding switch determines whether the VCA gain
response is exponential (EXP'L) or linear (LINEAR).

UNMOD – Press this button to place the module into
(4)
UNMOD mode. In UNMOD mode, the IN A signal passes to
the OUT jack without any modulation, and the signal level
is controlled by both the UNMOD GAIN and AMPLIFIER
GAIN knobs. IN B does not function in UNMOD mode.
MOD – Press the button to activate MOD mode. In MOD
(5)
mode, the circuit combines the IN A signal and the IN B
signal to produce an output signal that is a modulated
combination of the two input signals.
RATIO – Use this knob in MOD mode to offset the tune
(6)
control voltage that is sent out through the CV B jack.
This function only operates when MOD mode is selected.
TUNE – Use this knob in MOD mode to control the output
(7)
level of the tune control voltage sent out through both
the CV A and CV B jacks. This function only operates when
MOD mode is selected.
IN A – This knob controls the input level for the signal
(8)
coming in through the IN A jack.
IN B – This knob controls the input level for the signal
(9)
coming in through the IN B jack.
IN A / IN B – Use these input jacks to route in audio
(10)
signals for the internal modulation process via cables with
3.5 mm connectors.
CV A / CV B – Use these jacks to route TUNE (CV A and
(11)
CV B) and RATIO (CV B offset) control voltages out to the
two VCOs that typically supply the audio signals to the IN A
and IN B inputs to be modulated.
CV IN – Use this jack to route in control voltage signals for
(12)
remote control of the AMPLIFIER GAIN setting.
MOD – Use this jack to route in a trigger signal to remotely
(13)
activate MOD mode via a cable with 3.5 mm connectors.
GATE – Use this input jack to route in a gate signal to
(14)
turn the modulation circuit on and off via a cable with
3.5 mm connectors.
UNMOD – Use this jack to route in a trigger signal to
(15)
remotely switch off MOD mode via a cable with 3.5 mm
connectors
.
OUT – This jack sends out the final VCA signal via cable
(16)
with 3.5 mm connectors.
