Features & Specifications
Fully Analogue Voltage Controlled Amplifiers
10 HP wide (50.5mm), 20mm deep
Two independent and identical VCAs in one module
Current consumption: +12V 25ma, -12V 25ma
Linear or Logarithmic response switch
Dual linked audio inputs
Dual linked CV inputs
At normal levels (+/-5v), a very transparent utility VCA, but gain and bias can be set
to overdrive the signal with very pleasing distortion characteristics.
Description of Functionality
Gain
Together with the Init trimmers on the
rear, this knob sets the starting gain
of the VCA before CV is applied to it.
Turn to the right to add gain and
overdrive to the signal, or turn to
the left to ensure silence at times
when no CV input is present.
Signal Inputs
Inputs for the signal whose amplitude
you would like to control. Both inputs
are summed - useful for controlling
two sources together, for example
as an oscillator mixer.
CV Inputs
Inputs for the CVs used to control the
amplitude of the signal inputs. Both
inputs are summed - useful for applying
multiple CVs to the same amplifier, for
example, an ADSR amplitude envelope
and an LFO tremolo.

AVS-VCA-1
Dual VCA
2-position switch that chooses between
a linear (up) and logarithmic (down)
response for the VCA. When using
analogue envelopes such as the
AVS-ADSR-1, linear will generally be
used. However, when using digital,
linear-shaped envelopes, it may be
desirable to use the logarithmic
response. In this case, extra gain
may need to be applied in order to
achieve the desired output level.
The output of the CV-controlled
attenuated or boosted signal.

The bottom half of the module
is an identical reproduction of
the top half with entirely
independent circuitry.
