The Erica Synths Black 3109 VCF / VCA is a lowpass filter and voltage-controlled 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 Erica Synths' attempt to recreate the iconic sound of these synths, but there was also an 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.
Specs:
Audio level 10Vptp
Cutoff CV level (full span) -5V - +5V
VCA CV level 0 - +10V
Max power consumption 25mA@+12V, 25mA@-12V
Module width 10HP
Module depth 35mm
Cutoff - This is the manual cutoff control. An external CV is added to the knob position.
CV2 - This is the second cutoff CV input. It applies the CV without attenuation, therefore here you can connect the CV for 1V / oct tracking.
Vol Comp - This is the volume drop compensation switch. When it is ON, the volume will not drop when resonance is increased.
Audio Lvl - This is the audio signal level attenuator.
Resonance - This is the resonance control. In "classic" mode (VOL COMP switch set to OFF), the volume will drop slightly when the resonance is increased. If you set the VCF to self-oscillate and apply 1V / oct CV, you can use the module as a VCO. It works particularly well as bass drum synthesizer when punchy envelopes are applied to the CV input.
VCF CV1 LVL - This is the cutoff CV attenuverter. At 12:00 no CV is applied, turning the knob clockwise increases the CV amount, turning it counter-clockwise, the incoming CV is inverted.
VCA CV LV L- This is the VCA CV attenuator. If nothing is patched into VCA CV IN, it acts as VCA bias control - you need to dial it all way clockwise in order to open the VCA.
Input - This is the audio input of the module.
VCF CV In - This is the cutoff CV input with the attenuverter.
Output - This is the audio output.
VCA CV In - This is the VCA CV input. Please, note that the input is normalled to +10V and you need a 0 - +10V envelope to fully open the VCA.
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 centre 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.
