Utilitarian Audio & CV Mixer - (Version 2025)Combine up to four audio and or CV sources into one output, with independent manual level control. It can be used as a four-channel mixer or as two separate two-channel mixers, depending on the connection. If a cable is connected to the Master output but not to the 1+2 output, all channels will be summed at the Master output. If both the Master and 1+2 outputs are connected, the Master will output the mix of channels 3 and 4, while the 1+2 output will provide the mix of channels 1 and 2. Each pair of channels has an LED indicator that shows the presence of a signal.DIY-Kit-Type:THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module.

Befaco / Divkid - Stereo Strip
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.

DC is a unique and innovative module that combines the strength of both Averager and Unity Gain mixers without their weaknesses. Along with some additional unique features that make it stand out from other mixers on the market.To create DC we had to rethink the mixer, start from scratch, try new design, prototype many circuits and fail in order to succeed. The result is DC a new type of mixer that offer low noise floor, stable output signal and mix accurately signal without introducing any distortion, clipping, attenuation or unwanted noise and those regardless of the number of inputs signals or their gain.We called this new mixer design a «Combinator,» and the name «DC» stands for «Dual Combinator.» This versatile mixer can function as a dual-channel, mixing up to 3 inputs into a single output, or as a single-channel, allowing up to 5 inputs to be mixed into a single output.We put time and effort into the design of DC because we think that it is an essential module in any Eurorack system.

GOMA II is our new take on the classic attenuvertermixer concept. It stands for Generator, Offset, Mixer, Attenuverter.Featuring 4 channels within a 4HP width, GOMA II pushes the boundaries of space efficiency, maintaining intuitive operation and high-end components for max precision (low tolerance resistors, low noise/distortion opamps).GOMA II offers 4 channels to attenuate or polarize (attenuverter) any audio or CV signal. Additionally, each channel can act as a high precision voltage generator (–5V to +5V) to offset another channel or control external parameters.The 4 channels can be processed separately or summed through cascade mixing, which can extend further than a single module since all the GOMA family (I, II, Pro) can be daisy chained to unlock virtually infinite mixing.DIY-Kit-Type:SMD-Kit-1.
