ADDAC System - 216 Sum & Difference

available

There are two equal sections in this module labeled A and B.This module is a peculiar type of mixer that instead of just summing two input signals (X & Y), it also allows the possibility to subtract the two signals.It works both for audio and CV signals and hence allows for the possibility to get the diference of two CVs or cancel the phase of two audio signals. The resulting signal, of sum or subtraction, is then routed through a switchable (on/off) full rectification circuit labeled: Absolute. After this the gain of the mixed signal goes through another attenuverter labeled: Amplitude to control the resulting signal gain which, being an attenuverter, also allows the possibility to invert the incoming signal. After the Amplitude comes an AC/DC coupling switch followed by an bipolar Offset knob.Besides the normal output there’s also an inverted output for each of the A & B sections.The outputs of section A & B are also summed and sent to the Average Output.Using a single input, just the X or Y input, the module can also be used as a simple dual Attenuverter & Offset CV processor with full rectification and AC coupling options.Features:• 2 independent sections each with:• 2 inputs with gain attenuverters• Amplitude attenuverter and bipolar Offset• Absolute/Bipolar and AC/DC switches• Output and inverted output• 2 leds monitor the Output polarities and gain.DIY-Kit-Type:SMD-Kit-2.

ADDAC System - 713 Stereo Discrete Mixer

only 2 left

ADDAC713 is the stereo version of our 703 Discrete Mixer. Inspired by Moog’s CP3 mixer, this is a fully discrete analog mixer and it's not, by any means, your standard breakfast mixer, although it can behave like one.This is a wolf in sheep's clothing. Despite its harmless looks there's a dark snarly soul behind that panel that wants to take your sounds into a realm of gritty gnarly growls.This new version was initially thought of as a percussion mixer, with mono inputs and panning, to allow placing percussive voices in the stereo field, while keeping channel 4 in mono for low end sources like a kick drum or Bass. In the development process we slightly changed this initial idea, adding stereo inputs for the first 3 channels, but still kept the 4th channel in mono.All four [GAIN] controls go to extreme levels, the first 3 channels also feature [PAN] controls.Feedback is used to overdrive the whole mix. As the control is turned clockwise the sound will be clipped harder until it goes completely off, this happens as feedback is increased the audio bias reference also moves up, at extreme levels it offsets the whole signal upwards until it completely goes above the top rail clipping the whole signal hence the resulting gate effect.The [MASTER OUTPUT] sets the overall output gain of the mixer, the two LEDs monitor the audio output signal.The soft clipping switch engages an anti-click circuit which adds a low pass before the output, the switch allows 3 states: Soft low pass / Off / Hard low passFeatures:• Three channels with stereo inputs, gain and pan knob• One channel with mono input and gain knob• Feedback/gate knob• Master output volume knob• Soft clipping switchDIY-Kit-Type:SMD-Kit-1.

ADDAC System - 805 VC Signal Router V2

available

Inspired by our ADDAC701 VCO waveform mixing section, our new VC Signal Router also updates our legacy X-Fade/Panner to a stereo configuration that also allows 4 quadrant mixing.Featuring two dedicated X-faders and a stereo VCA that can also be used as a third X-Fader. All controls have their own CV inputs and dedicated Attenuverters for precision control.4 quadrant mixing is achieved by using the stereo Master as a X-fader between left and right channels, this way you can plug 4 audio sources and sweep/crossfade between each and any of them using the 3 x-faders. Plug any 4 sources (4 waveforms of a VCO, 4 LFOs, 4 envelopes...) and sweep through morph through or have them all mixed together.For other configuration types Left and Right X-fader channels can be routed through the Master stereo VCA or sent directly to the outputs. A stereo Direct input can also be routed through the Master VCA or sent straight to the outputs.The Mono Sum output always mix Left and Right outputs together allowing the possibility to use the module as a peculiar 6 channel mono mixer.It can be used for both Audio or CV Signals.Features:• 6 mono inputs• 2 dedicated X-faders with Control knob + CV Input and Attenuverter Each X-fader can be routed through the Master mix or straight into the outputs.• Master channel can be used as a stereo VCA or an X-fader• Stereo direct inputs can be routed through the Master mix or straight into the outputs.• Fully analog audio path with high quality/low noise VCAs.DIY-Kit-Type:SMD-Kit-2.

Befaco - Hexmix

only 1 left

Hexmix System is a six channel performance mixer specially designed for Eurorack.The system has two separate modules, the core of the mixer: Hexmix that has six channels with three band EQ, mute, pan and EQ section on the master, and Hexpander that add three auxiliar sends per channel, PFL, individual outs and balanced output.The mixer has a strong inspiration in classical DJ mixers, providing sharp EQ’s for enhanced performance, auxilliar send for effects and individual outputs to record your performance per channel.The system is designed to be placed in 6U, instead of the traditional 3U paradigm in Eurorack. So we will have every feature for each channel vertically as a conventional tabletop mixing deck.Six channel mixer with three band EQ, vactrol mutes, pan and volume control per channel.Inputs for every channel are located at left side of Hexmix. Each jack is normalized to a VCA Expander connection in the back, so if you have a Hexmix VCA , you will have the output of each VCA to every input. connecting a jack in any input will disconnect whatever is coming from VCA.Gain is set to unity, so it will act as an attenuator of the input signal. Mutes are clickless, as they are vactrol based. This circuit provide some decay on the mutes, rather than a sharp cut.Swithces have latch position and momentary ones to unmute the channel, providing some really nice performative capabilities.EQs are quite sharp (12dB) inspired in classic dj mixers to aggresively cut selected frequencies.Master section has it’s own EQ and volume control for the mix of all channels. Master EQ is softer than individual channel’s (6dB) and it’s meant to provide control over the final mix.It’s possible to change output level from line to synth with a switch located in the back.This will be pretty useful when used in combination with hexpander, that provides a balanced out at line level. Like this its possible to have a mix at synth level to re-route the master signal while having an output to PAFeatures:• Six Channel Performance Mixer• Three Band EQ per channel inspired in classical DJ mixers• Vactrol based mutes with momentary action.• Pan and Volume control• VCA Expander connection to plug every channel of an Hexmix VCA directly.• Selectable Line or Modular output level.DIY-Kit-Type:THT-Kit-1.

Befaco / Divkid - Stereo Strip

available

Stereo Strip takes the idea of a channel strip and makes it modular. We hope that by bringing this long-established component of the audio engineering world into the Eurorack environment and by adding CV control over its key parameters that you will find new, creative ways to use it in your patches!It features stereo inputs and outputs for audio or CV with EQ, voltage controlled panning, stereo VCA, performable mute and input/output level switching for Eurorack or line level uses. Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.Stereo Strip was designed to be a creative part of a modular patch. Creating stereo images from mono sources, shaping and modulating existing stereo images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.The addition of line level gain boosting (for the input) or reduction (for the output) allow it to work as a stereo input or output interface for external gear with the advantage of the VCA, panning and the EQ to shape the sound. Experiment with bringing external gear into the Eurorack format and then shape and modulate those sounds them on the way in!Try patching Stereo Strip anywhere you would place a VCA in a system and/or explore its EQ and voltage controlled panning, which are rarer additions to the sound sculpting options for the Eurorack format.This module is designed in collaboration with Ben Wilson aka Divkid.Features:• 3 band EQ• Panning (manual and voltage controlled)• VCA level control (manual or voltage controlled)• 3 way performance muting (on-off-momentary)• Soft clipping limiter (distortion!)• Line level input and/or output adjustmentDIY-Kit-Type:SMD-Kit-1.
