Introduction
2 modules in one:
Two independent VCAs in one module. VCAs are amplifiers whose
gains are under voltage control. This means you can use a modulation CV,
such as an LFO or EG signal, to modulate the level of another signal.
A typical use would be the output from an envelope generator altering
the volume level of a signal, such as a fiilter output.
Controls In Detail
The 2 VCAs are identical, except that VCA 2 does not have a Input
Signal level control.
IN LEVEL
Alters the input signal level
CV LEVEL
Alters the CV level, to adjust the amount of VCA modulation.
OUT LEVEL
Alters the output signal level.
Sockets In Detail
IN
VCA Signal input. Normally the signal would be audio, but CV signals
can also be modulated.
CV
CV signal input for VCA modulation.
OUT
Output from the VCA
