Erica Synths PICO VCA2 User manual

Thank you for purchasing Erica Synths Pico Series module!
With Pico Series we challenged ourselves – can we make ANY superior
functionality synth module 3HP wide and affordable?
Yes, we can.
The Erica Synths Pico VCA2 is compact voltage controlled amplifier module,
based on reliable AS3330 chip. It features two independent channels, and the
first one comes with the manual offset adjustment, useful for full span
vibrato effects. Audio and CV inputs of the first VCA are normalled to the
second one, so the module can also be used as a buffered audio splitter. VCAs
are DC coupled, and they can be used for controlling amplitude of control
voltage signals.

This is the audio input of the first
VCA. It’s DC coupled, so, it also
will work for controlling an
amplitude of the control
voltages (LFOs, for example) Adjust the VCA bias manually, meaning –
you can offset the CV in order to have
desired amplitude modulation range on
the output. For example, for a tremolo
effect, you do not want the VCA close
completely at negative CVs from the LFO,
therefore using the BIAS control, you can
offset the CV1 so that it’s in 0-+10V range,
instead of -5V - +5V
This is the CV input of the first
VCA, It has linear response
This is the input of the second VCA.
It’s normalled to the input of the
first one, so, if nothing is patched
here, the signal from the first input
will be automatically applied to
this input, and the audio or CV gets
split into two channels
This is the output of the first VCA
This is the CV input of the second VCA.
It’s normalled to the CV1 input
This is the output of the second VCA
