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.

Notes: Premium analogue delay from Erica's flagship Black Series range. Two bucket brigade device delay lines work simultaneously with smooth crossfading and tons of voltage control. Lovely.

Supplier's Notes:
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 difference in sound. Erica Black series consist of range of modules that are needed to put together entire synth. Enjoy!

The Erica Synths Black BBD is one of kind analogue delay module. It features two BBD lines: short, 1024 stage and long, 4096 stage, that work simultaneously and you can smoothly fade between those two, thus creating distinct multitap effect.

Furthermore, an advanced BBD clock noise cancellation circuit is implemented that reduces unwanted BBD noise without filtering higher frequencies of audio signal. Most of parameters are voltage controlled, which allows to integrate the module in complex modular setups.

Time

This is delay time manual control.

Because of BBD clock suspension circuit, delay time can be pushed in extremely long regions, however in that case BBD clock noise may appear. The Time CV is added to the knob setting.

In level

This is the input attenuator switch. Select among full amplitude, half amplitude and audio off.

BBD mode

This control smoothly fades between short and long delays. Any setting in-between will result in distinct multitap delay effect.

LFO rate

Adjust the internal modulation LFO rate. The internal LFO controls delay time, and it's automatically disengaged, when an external modulation signal is connected. The LED gives visual feedback on the LFO rate.

LFO shape

Select the LFO shape. Three shapes are available - triangle, square and in-between shape - mix of triangle and square.

Input

This is the audio input of the module. This is manual Dry/Wet mix. The MIX CV is added to the knob setting.

Colour

Even though the module has BBD clock suspension circuit, the colour switch provides extra lowpass filtering of the signal. At top setting no filtering is applied, at lower settings increasing filtering is present.

Feedback

This is the delay feedback manual control. In extreme clockwise settings the module goes into self-oscillation, and by adjusting delay time and BBD mode settings, the module becomes a drone machine. The FBK CV is added to the knob setting.

CV level

This is the Time CV level attenuator. If nothing is patched into TIME CV socket, it controls the internal LFO amplitude.

WET out

This is the WET signal output of the module - use it for advanced patches.

Out

This is the main output of the module.

Time CV; FBK CV; Mix CV;
These are CV inputs for Time, Feedback and Dry/Wet mix.

SPECS:
Audio level 10Vptp
CV level (full span) -5V - +5V
Power consumption +95mA, -81mA
Module width 12HP
Module depth 35mm

Notes: Erica Synths Black Code Source Expander takes the Code Source to the next level by adding autobend feature and more noise/CV modes.

Autobend provides a useful attack envelope for the internal clock generator's pitch and some outside CV control. This feature helps to quickly achieve authentic chip-tune percussion and oldschool electronic game sounds.

Use the ribbon cable supplied with the module to connect the Expander to the Code Source! To connect the Expander you will need to remove the security jumper from the socket on the Code Source module. Pay close attention to the connector socket marking and do not mix it up with the PSU connector! The Code Source Expander will work only with the Code Source module and is not intended to work as a standalone module. Connecting PSU to the Expander will permanently damage it.

Technical specifications:

Power consumption: +16 mA, -11mA
Module width: 6HP
Module depth: 25 mm

Notes: Erica Synths Black Code Source is a unique design, true stereo digital noise or dual random CV generator using a complicated calculation of polynomials of various configurations.

Basically, you can consider it as a sample&hold noise generator, that is able to "rewind" or repeat incredibly long sequences of seemingly random levels. X, Y and S controls together provide over 4000 different dual CV sequences for every MODE switch position, that can be triggered via the S TRIG.

Technical specifications:

Output level: -5...+5V (or 0...+10V)
CV level: -10V - +10V
Power consumption: +143mA, -64mA
Module width: 10HP
Module depth: 35mm

Notes: Erica Black CV Processor allows you to manage CV signal levels and polarity.

It contains two parts; the input of the bottom one is normalled to the output of the top one, and if signal is plugged in Input of the top part only, it is split in two signals, each of which can be independently altered.

Erica Black Series includes high-end, unique functionality and superior quality modules.

Notes: The Black Digital Noise is Erica Synths' pathological brainchild. A unique noise module that makes wide range of noise effects; almost pure white noise, Atari console-like one bit noise and other crazy, more or less predictable sounds.

Notes: Take a DJ-mixer-style combined high-pass and low-pass filter, cram it into Eurorack and you have the DJ VCF. A simple formula, but one perfected by Erica's attention to detail, with CV control and adjustable resonance.

Supplier's Notes:
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 cutoff 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 the performance, as well as unconventional timbre modulations that are hard to achieve with conventional state variable filters. The Black DJ VCF is a fully analogue design and consists of two VCFs - highpass and lowpass in series and the filter management is done by complex CV routing.

CUTOFF
This is the main control of the module - manual cutoff frequency adjustment with a twist - it's fully open when the cutoff knob is set to 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is initiated

AUDIO LVL
Adjust the audio signal level

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

CV1 LVL
This is the cuto CV attenuverter. Adjust the CV level to your taste! Notice that the cutoff CV works differently compared to conventional state variable filters - it sweeps the filter from closed lowpass through fully open to closed highpass

CV2 LVL
This is another cuto CV attenuator

CV2 IN
This is the cuto CV2 input, which is controlled by the attenuator knob

AUDIO IN
Patch your audio signal here.

Notes: Erica Synths Black Double Bass is unique module that combines two transistor suboscillators (-1 and -2 octaves) and lowpass filter. It does not make sound on its own, but it will turn any VCO or beeper into massive bass sound with CV control over octave mix and cutoff frequency. Sync input that resets suboscillators on incoming pulse, provides even more versatility in sound design. The module can be also provide aggressive distortion, when used with percussive sounds like bassdrums.

Notes: 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 Erica Synths prioritised design and usability first Big knobs are assigned to functions that make difference in sound. Erica Black series consist of range of modules that are needed to put together entire synth. Enjoy!

The Erica Synths Black Dual ASR EG is a versatile, full analogue voltage controlled looping envelope generator and low frequency oscillator with manually and voltage controlled shape and rate, designed for use in advanced modular systems.

It has two identical parts, each featuring all typical envelope generator controls and bonus features - the end of the cycle output and bi-polar LFO output. When in loop mode the shortest attack and decay settings turn the module into voltage controlled drone oscillator with adjustable waveform (it will not track 1V/oct, though).

Notes: Two full ADSR EGs, two unique LFOs with plenty of features just in 10HP!

Erica Synths have managed to put two full ADSR envelope generators, you can adjust one by one or two simultaneous AD/ASR envelope generators and unique, not seen before functionality LFO in just 10HP! This saves a lot of rack space, you can use for other Black Series modules!

Notes: Erica Synths Black Dual VCF is a dual multimode filter with CV control over cutoff and resonance for serious modular patches.

At the core of this VCF is a highly stable, custom multimode VCF chip AS3320 (produced in Riga, btw). This module can be used as two independent VCFs with simultaneous HP, BP and LP outputs, controls can be linked to stereo application and both VCFs can be chained in series or parallel to the summing output for ultimate modulations. Bonus feature - the 16 band spectrum analyser gives you visual feedback on what happens on summing output.

Audio output amplitude: 10 Vptp
CV input (full sweep): 10 Vptp
Panel width: 18HP
Module depth: 35mm

Notes: Erica Synths Black Envelope Generator is a compact, fully analogue envelope generator with some cool bonus features like gated loop and gate delay for nice acid basslines and very slow drones.

Erica Synths have introduced a distinct looping feature (when the gate patchcable is patched, looping starts on gate on) and Gate Delay - the module outputs delayed gate signal after Attack stage. Chain up several (4-5) Envelope Generators, each with delayed gate to create evolving polyphonic synth-like pads!

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, design and usability was prioritised over module wirth. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.

Release time (short/long): 0...3"/35"

Panel width: 8HP

Module depth: 25mm

Power consumption: 25mA@+12V, 15mA@-12V

Notes: The Erica Synths Envelope Generator 2 is a re-triggerable, looping envelope generator with some unconventional features that are very useful for experimental setups. What sets the Black EG2 apart from other envelope generators is its optional GATE LENGTH setting, which allows for generating full ADSR envelopes even if a short trigger is used at the input. Likewise, in LOOP mode, the module outputs a full ADSR envelope instead of a classical AD envelope. The gate length is both manual and CV controlled, which allows for using this envelope generator in compact modular setups controlled by trigger sequencers only.

The Erica Synths Envelope Generator 2 is a re-triggerable, looping envelope generator with some unconventional features that are very useful for experimental setups. What sets the Black EG2 apart from other envelope generators is its optional GATE LENGTH setting, which allows for generating full ADSR envelopes even if a short trigger is used at the input. Likewise, in LOOP mode, the module outputs a full ADSR envelope instead of a classical AD envelope. The gate length is both manual and CV controlled, which allows for using this envelope generator in compact modular setups controlled by trigger sequencers only.

Notes: Multi-function eight-channel LFO, joystick, movement recorder and drone oscillator that packs in lots more functionality than you might expect. A real modulation powerhouse in a compact format.

Supplier's Notes:
Erica Synths Black Joystick2 is 8 channel multi functional CV and sound source - joystick, movement recorder, distinct LFO and drone/noise oscillator. It provides great interaction with the modular system and allows to develop unconventional modulation patterns instantly.

Notes: The Erica Synths Black K-Phaser is our take on a classical, genre defining FX unit - the Krautrock Phaser. It retains the original concept of 8 all-pass filters with photoresistors, but we redesigned the filters and modulation circuit and added several unique features. A dip switch allows for selecting the number of filter stages involved in the resonance path, while the resonance attenuverter brings in never-heard-before feedback artefacts, and most importantly - the SPREAD mode detunes the all-pass filters for even more distinct behaviour. A built-in voltage controlled LFO with selectable waveforms expands the modulation possibilities of the phaser and can be used as an independent modulation source for your modular system as well. The Black K-Phaser is our tribute to the German electronic music pioneers that largely shaped the sound of electronic music worldwide.

Notes: One of the most authentic sounding emulations of the famous Russian synth the Formanta Radio Factory Polivoks in 10HP

Erica Synths Black Polivoks VCF is one of the most authentic sounding emulations of the famous Russian synth the Formanta Radio Factory Polivoks.

The original Russian ICs K140UD12 are used in the sound circuit. Several updates were added to adapt the VCF for contemporary modular synth demands, it has independently buffered inputs, extended Cutoff knob, eliminated clicks when switching filter modes and output stage added to eliminate signal inversion. The result is a much punchier bass sound and very smooth controls.

Notes: Erica Synths Black Quad VCA2 is a versatile four channel voltage controlled amplifier and mixer module for use in complex modular systems. Each channel has linear/logarithmic response selector and signal level indicator LED. All outputs are sequentially mixed and CV inputs are normalled to each other, so you can use the module in various configurations. If no CV is applied, the Black Quad VCA2 performs as a signal mixer, and the 4th channel is DC coupled for controlling CV sources, as well.

Notes: The Erica Synths Black Ring-Xfade is an extremely versatile module for sound shaping. It consists of two unconventional ringmodulators/waveshapers, a crossfader that works both for audio and CV and a VCA. Unlike conventional ringmodulator that works only with a signal present on both signal and carrier inputs, the Black Ring-Xfade passes through the signal without alteration, if no carrier is present, but low level signals on the carrier input result in unique waveshaping. Add the crossfader between two ringmodulators (or as a separate unit) topped up with the VCA, and you have an amplitude modulation powerplant in 10HP!

Ring1 CV; Ring2 CV
These are the ringmodulator carrier (CV level) level controls. Unlike conventional ringmodulator, this one passes signal unaltered, if RING CV is turned down. With increasing Ring CV level a slight waveshaping turns into proper ringmodulation.

Xfade
This is a manual Crossfade control. This fades smoothly between signals patched into XFADE IN1 and XFADE IN2. The XFADE CV is added to the knob position.

Coupling
Set the Crossfader mode - AC is optimized for use with the audio signals, DC - for control voltages (but it will work fine with audio, as well).

Ring 1; Ring 2
The green LEDs give visual feedback on signal levels, applied to XFADE IN1 and XFADE IN2 respectively.

Vol CV
Select the VCA CV response. A 0-10V setting is intended for use with the envelope generator, a -5V - +5V setting - for nice tremolos with a LFO.

Xfade IN1; Xfade IN2
These are the Crossfader inputs. They are normalled to the Ringmodulator ouputs, so, if nothing is patched here, you can crossfade between two ringmodulated signals.

Xfade CV
This is the Crossfader CV input. The CV is added to the XFADE knob setting.

VOL CV
This is the VCA CV input. The VCA is post-crossfade - it controls the amplitude of a resulting signal after the crossfader. It will also work with low frequency control voltages applied to the XFADE Ins - nice for designing unconventional modulations.

Ring1 Out; Ring2 Out
These are the ringmodulator outputs.

Xfade Out
This is the Crossfader output and the main output of the module.

Ring2 In; Ring2 CV
These are the second Ringmoduator signal and carrier inputs respectively. These two are normalled to the RING1 inputs, and if no signal is patched here, the duplicate the first Ringmodulator. Interesting trick is to set RING CVs at different levels and crossfade between two ringmodulator signals.

Ring1 IN; Ring1 CV
These are the first Ringmoduator signal and carrier inputs respectively.

Fade L; Fade R
The red LEDs indicate the crossfader position.

Xfade CV LVL
This is a crossfade CV level attenuator. By adjusting it you can control a span of fading between inputs.
