BLACK QUAD VCA2
LEVEL1 LEVEL2
THANK YOU FOR PURCHASING ERICA SYNTHS
BLACK SERIES MODULE!
Erica Black Series include high-end, unique functionality and superior quality
modules. Only the best, highest quality components are used, all inputs and outputs
are protected against undesired overvoltage. When designing Black Series, we put
design and usability superior. Big knobs are assigned to key functions of the
module, which makes Black Series ideal for live performances. Enjoy!
Erica Synths Black Quad VCA2 is a versatile four channel voltage controlled
amplifier and mixer module for use in complex modular systems. Each channel has
linear/logarithmic response selector and signal level indicator LED. All outputs are
sequentially mixed and CV inputs are normalled to each other, so you can use the
module in various configurations. If no CV is applied, the Black Quad VCA2
performs as a signal mixer, and the 4th channel is DC coupled for controlling CV
sources, as well.
FEATURES:
4 independent VCAs
Selectable lin/log response for each channel
Manual CV bias and signal level adjustment
Sequential output mixing
Signal level indicator LEDs
SPECS:
CV level -10V - +10V
Attenuation level:
CV = 0V (max attenuation) -80dB
CV = +10V +3dB
Response lin/log
Power consumption 64mA @ +12, 62mA @ -12V
Module width 10HP
Module depth 35mm

Give visual feedback on the audio signal level on each channel
LEVEL 1, 2 , 3, 4
Select input level! Upper setting passes the audio at gain 1, middle setting – gain
0,5, bottom setting turns audio input o.
LIN / LOG
Select between linear or logarithmic response. Please note, that in LOG mode also
the level potentiometer will have dierent response, therefore, when selecting
between modes, you may need to readjust potentiometer settings
CV1, 2, 3, 4
Apply CV signals from EG, LFO or any modulator here! CV inputs are normalled in
series, meaning, if CV is applied to CV1 only, it will be copied to other inputs. If you
want to use some inputs without any CV, insert the patchcable in the CV to
terminate the internal normalling
IN1, 2, 3, 4
Patch your audio signals here.
OUT1, 2, 3, 4
These are VCA outputs. Interesting thing is that outputs are automatically mixed to the
next output to the right, if nothing is plugged in the relevant output. Meaning, if you
wish to have all outputs mixed together, you patch the cable in OUT4 only. If you plug
a patch cables in OUT2 and OUT4, you get independent sums of VCA1+VCA2 and
VCA3+VCA4. If you have patch cables in all 4 outputs, you have 4 independent VCAs.
SAFETY INSTRUCTIONS
Please follow the instructions for use of the Erica Synths module below,
‘cause only this will guarantee proper operation of the module and
ensure warranty from Erica Synths.
Water is lethal for most of the electric devices, unless they are made

-20° C. If you have transported module in extreme low temperatures,
leave it in room temperature for an hour before plugging it in.
Transport the instrument carefully, never let it drop or fall
over. Warranty does not apply to modules with visual
damages.
The module has to be shipped in the original packaging
only. Any module shipped to us for return, exchange and/or
warranty repair has to be in its original packaging. All other
deliveries will be rejected and returned to you. Make sure
you keep the original packaging and technical documentation.
This device complies to the EU guidelines and is manufactured RoHS conforming without use of lead, mercury,
