THANK YOU FOR CHOOSING 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 CV Tools is full
analogue CV and audio processor
module designed for advanced
manipulations with signals – mixing,
scaling, osetting, waveshaping, etc.
The module has several configurations
achievable via jumpers on the back
of the module.
FEATURES:
2x3 channel audio and CV mixer with
unity gain
2x attenuverters/boosters and
bipolar oset
Min and Max function extractor
+5V reference
LED bioplar level indicators
Configurable features – see the
description below
Scale A and Scale B knobs
adjust attenuation/boosting/
inverting levels for each
mixer output.
At 12 o’clock there will be no
signal on SCL output. Turning
the knob clockwise, the signal
level will increase until it’s
boosted to gain 2. Turning the
knob counter clockwise, the
signal is inverted
and gradually boosted to
the gain 2
These are oset control
knobs. At 12 o’clock the
signal on SCL outputs has
0 oset (for example,
if regular -5V - +5V
sinewave LFO is applied
to the any of mixer inputs,
the signal on the relevant
SCL output will be the
sinewave oscillating
around 0V), turning
the knob CW up to 10V
positive oset is added to
the incoming signal (you
can basically transpose
incoming CV, for example
or oset the middle
point of the sinewave
above 0V), turning the
knob CCW will result in
the negative oset
These are inputs of the
first mixer (A). If nothing is
patched in IN A1,
the +5V reference voltage
will appear on MIXA
output. You can also use
this as a CVs scaler to turn
any bipolar Cvs patched in
IN A2 into unipolar 1V/oct
inputs on VCOs or
opening VCAs!
These are inputs of
the second
mixer (B)
Scaled outputs take the
relevant mixer output
signal and pass it through
Scaler circuit (it’s basically
attenuverter with gain 2 –
it can boost and invert the
incoming signal. Boosting
large amplitude audio
signals will result in over-
drive eect) and Oset
circuit that osets audio
and CV signals in positive
or negative directions
These outputs derive
Maximum and Minimum
curves of MixA and MixB
signals. If several CVs are
applied to the inputs, Max
and Min curves will be
seemingly random CVs
that reflect interaction
between MixA and
MixB; if audio signals
are applied, the result on
Min and Max outputs is
extreme waveshaping
These are A and B mixer
outputs, the mixer works
with preset gain of 1

Summary

Erica Synths Black CV Tools Module Overview and Controls

Module Description

Full analogue CV and audio processor module for advanced signal manipulation: mixing, scaling, offsetting, waveshaping.

Offset Control Knobs

Explains offset control knobs, their 0-10V positive/negative offset adjustment and effect on incoming signals.

Mixer Inputs and Scaling

Details Mixer A inputs, including the +5V reference, and how Scale A/B knobs adjust signal levels, boost, and invert.

Mixer Outputs and Scaled Signals

Describes mixer outputs (A/B) with unity gain and scaled outputs processed by attenuverters and offset circuits.

Min;Max Outputs

Explains outputs deriving maximum and minimum signal curves from mixer inputs for complex waveshaping.

Jumper Configuration

NORM A1 Jumper Setting

Configures CV Mixer A for optional +5V or -5V output offset, useful for translating CV ranges.

MATH IN A;B Jumper Settings

Selects MIN/MAX function source: MIX signals or SCALED signals for varied processing.

MIN;MAX OUT SELECT Jumper Settings

Allows MIN/MAX outputs to act as signal splitters or provide inverse mix outputs.
