IN A
- Input to VCA A.
The signal inserted here is amplified by
Voltage Controlled Amplifier A (at an amount
controlled by the
CV A
[3]
input) and sent out
the
VCA A out
[5]
jack.
[2]
IN B
- Input to VCA B.
The signal inserted here is amplified by
Voltage Controlled Amplifier B (at an amount
controlled by the
CV B
[3]
input) and sent out
the
VCA B out
[5]
jack.
IN A
[1]
is normalled to
IN B
[2]
, so if nothing
is inserted into
IN B
, then
IN A
feeds both
VCA A and VCA B.
[3]
CV A
- The CV input for controlling the linear
amplification level of VCA A.
The input range is 0 V to 10 V. At 0 , no output appears at
VCA A out
[5]
. 5 V results in unity
gain (meaning the voltage at
VCA A out
[5]
is the same as the voltage at
IN A
[1]
). Voltages
above 5V increase the gain, with a 10 V CV input resulting in a maximum gain of +6 dB.
The amount of voltage present at
CV A
[3]
is indicated by the brightness of the LED.
Common CV sources include envelope/function generators (for shaping the volume of the signal
patched into
IN A
[1]
) or LFOs (for generating tremolo effects).
[4]
CV B
- The CV input for controlling the linear amplification level of VCA B.
CV A
[3]
is normalled to
CV B
[4]
, so if nothing is inserted into
CV B
, then
CV A
controls the
amplification for both VCA A and VCA B.
[5]
VCA A out
- The output of Voltage Controlled Amplifier A.
If nothing is connected to this jack, then the output of VCA A is mixed with the output of VCA B,
and sent to the
VCA B out
[6]
jack.
[6]
VCA B out
- The output of Voltage Controlled Amplifier B.
If nothing is connected to the
VCA A out
[5]
jack, then it outputs the sum of VCA A and VCA B.
