BLACK
LOW PASS VCF
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, put design and usability superior. Big knobs are assigned to functions
that make dierence in sound. Erica Black series consist of range of modules
that are needed to put together entire synth. Enjoy!
The Erica Synths Black Low Pass VCF is designed for analogue purists, who
take sound design seriously. It’s highly stable, 24dB/oct resonant low pass VCF
with voltage control over cuto (two CV inputs, one is with an attenuverter)
and resonance. Bonus features are built in post-filter overdrive circuit with user
adjustable drive amount and the Black Filter Coupler connector. When used in
combination with the Black High Pass VCF and the Black Filter Coupler, you get
a Holy Trinity of VCFs for an ultimate analogue modular system.
FEATURES:
Voltage control over cuto and resonance
Gain loss compensation on high resonance
Cuto CV attenuverter
Built in adjustable overdrive circuit
Filter coupler connector
CUTOFF
This is the main control of the module – manual cuto
frequency adjustment. The incoming CV is added to the
cuto knob position.
DRIVE
For extreme results, flip the DRIVE switch ON! This will
apply post-filter drive. You can preset drive level to your
taste by adjusting a trimpot close to the switch on the
back side of the module.
RESO CV IN
This is the resonance CV input.
IN LEVEL
Adjust the audio signal level.
RESONANCE
Adjust the resonance level manually. On settings over
1PM the filter will start to self-oscillate. The incoming CV is
added to the resonance knob position.
CV1 LEVEL
This is cuto CV attenuverter. Adjust the CV level to your
taste!
RESO CV LEVEL
Adjust the resonance CV level to your taste.
CV1; CV2
These are the cuto CV inputs. The CV1 level is adjustable
by CV1 LEVEL attenuverter knob, CV2 is applied to the
cuto without attenuation.
INPUT
Patch your audio signals here.
OUT
This is the audio output of the module.
