BLACK DJ VCF
THANK YOU FOR PURCHASING THIS ERICA SYNTHS
BLACK SERIES MODULE!
The Erica Black Series includes high-end modules with unique functionality and
superior build quality. Only the best, highest quality components are used, all inputs
and outputs are protected against undesired overvoltage. When designing the
Black Series, we placed an emphasis on usability with the goal of providing an
enjoyable user experience. Big knobs are assigned to functions that make
dierences in sound. The Erica Black Series consists of a range of modules that are
needed to put together an entire synth. Enjoy!
As its name suggests, the Erica Synths Black DJ VCF provides sound treatment
functionality typically found on DJ decks – it is fully open when the cuto knob is set
to 12:00. When turned counter-clockwise, lowpass filtering is applied and when
turned clockwise, highpass filtering is applied. The filter also has a nice-sounding
resonance parameter. This module provides hands-on control over the sound
during performance, as well as unconventional timbre modulations that are hard
to achieve with conventional state variable filters. The Black DJ VCF is of a fully
analogue design and consists of two VCFs – highpass and lowpass in series and the
filter management is done by complex CV routing.
FEATURES:
Fully analogue DJ-style VCF
Manual resonance control
Cuto CV attenuverter and attenuator
Input and output
Protection against undesired overvoltage
SPECS:
Audio level 10Vptp
CV level -10V - +10V
Filter slope 24dB/oct
Power consumption +55mA, -58mA
Module width 10HP
Module depth 35mm
AUDIO LVL
Adjust the audio signal level
CV1 LVL
This is the cuto CV attenuverter.
Adjust the CV level to your taste!
Notice thatthe cuto CV works
dierently compared to conventional
state variable filters – it sweeps the
filter from closed lowpass through
fully open to closed highpass

CV1 IN
This is the cuto CV1 input. The CV1
level is adjustable by the CV1 LEVEL

CUTOFF
This is the main control of the module –
manual cuto frequency adjustment
with a twist – it’s fully open when the
cuto knob is set to 12:00. When turned
counter-clockwise, lowpass filtering is
applied and when turned clockwise,
highpass filtering is initiated
RESONANCE
Adjust the resonance level manually.
On settings over 1PM, the filter will
start to self-oscillate. The resonance
is incoming audio signal-sensitive –
a signal of greater amplitude may
reduce the impact of resonance on
the resulting sound
CV2 LVL
This is another cuto CV attenuator
CV2 IN
This is the cuto CV2 input, which is
controlled by the attenuator knob
OUTPUT
This is the audio output of the module
