BLACK 3109 VCF/VCA
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 differences in sound. The Erica Black Series consists of a range of
modules that are needed to put together an entire synth. Enjoy! The Erica
Synths Black 3109 VCF/VCA is a lowpass filter and voltage-con-trolled amplifier
combo built around the AS3109 VCF integrated circuit, a contemporary version
of the IR3109 chip, found on vintage Roland synths such as the Jupiter series,
Juno series and the SH-101. The 3109 VCF/VCA is our attempt to recreate the
iconic sound of these synths, but we also aim to improve upon it. Filters
based on IR3109 had several drawbacks, including
a volume drop when the resonance is increased so we added a volume drop
compensation as well as a built-in VCA for more versatility in compact setups.
Additionally, 1V/oct tuning is implemented so you can use this module for
perfect VCF keyboard tracking and also as a VCO.

The Black 3109 VCF/VCA has a hidden feature – compatibility with the Black
Filter Coupler connector. The Erica Synths Black Filter Coupler is a satellite
module for the Black High Pass and the Black Low Pass VCFs and now also the
Black 3109 VCF/VCA. Similar to classical Moog systems, it turns both high-pass
and low-pass filters in to Bandpass and Band Reject filters with adjustable and
CV controllable bandwidth and center frequency and therefore significantly
expands the functionality of your modular system. Please note that the Black
Filter Coupler works only with Erica Synths modules and you need both the
Black High Pass and Low Pass VCFs.
