Attenuator
available
Quad Attenuator/Inverter, Splitter, and Offset GeneratorScale your audio or CV sources and route them to various destinations with this versatile utility. It consists of four identical unity gain amplifiers. Each amplifier can multiply an incoming signal by values ranging from 0 to 1 (for attenuation) or from 0 to -1 (for inverting attenuation). The input of each channel is normalled to the input of the next channel, allowing for easy signal routing from one input to the subsequent ones.The first channel is normalled to 10V, enabling the module to function as an offset generator when no input is connected.Features:• Inversion switch per channel.• Precise zero at the left side of the pots.• Four level LEDs indicate output level and polarity.• Cascaded input topologyDIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder.

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.

The CubuSynth 6xLevel module is a 8 HP passive attenuator, which allows scaling of CV and audio signals. The inputs are normalized from the outputs above, which allows passive multiplication with attenuation. The normalized path is attenuated by the potentiometer before, so you can also create very subtle changes (e.g. Fine tune a VCO). The silver lines on the front panel mark the normalisation routing.Note, that it is a passive module, for multiplying non-precise voltages. It is recommended to not use more than 3 outputs from the same input.Features:• 6 individual attenuators• flexible passive multiple (1x6, 2x3, 3x2, 1x4 + 1x2)• normalized inputs from output aboveDIY-Kit-Type:THT-Kit-1.

Macro ControllerKNOBI is a multi-tool able to mix, attenuate, invert, display and multiply any kind of signal. Knobi can serve a wide range of purposes thanks to its internal signal path that makes use of some of the most useful building blocks of analog synthesis: a 4-channel mixer, a three-range offset, an attenuverter, a fixed manual gate and lastly a cascading multiple derived from the output stage of Agogô.a, b, c and d are Knobi’s inputs while r is a fixed 5v reference output. The toggle switch next to d sets the range of the offset - the big knob below the meter. Connect a signal into one of the inputs to visualize its voltage value in the three digits meter. Keep in mind that this reading happens post offset and attenuverter - the smaller knob with (-) and (+) indications.The pushbutton next to x4 adds a gate of 5v to the mix: with no input connected it will act as a manual gate output. Autopatch the r reference output into one of the inputs to use Knobi as a macro controller thanks the offset knob and switch to set the range and the attenuverter.x1, x2, x3 and x4 are all cascading copies of the final signal path. Plugging a cable will break the normalization and the multiplication will reset starting from the next output. Four cables plugged in will output a copy at the same factor x1 - unity gain - making Knobi a versatile buffered multiple.Features:• Thermally compensated 5v voltage source with dedicated output.• Four channel mixer with four buffered output.• Built in 3 digits voltage meter post mix / attenuation / inversion.• Offset with a dedicated three positions range toggle.• Manual gate button tied to the mix.• 4 cascading outputs in an open design configuration.• Unique signal path: mix - attenuate - invert - add - visualize - multiplicate.• “Whatever” power connector a.k.a. don’t mind the polarity.DIY-Kit-Type:SMD-Kit-1.

The SetonixSynth Noise Complaint! is a passive utility module which provides a bank of four passive attenuators which can be used with audio or CV. Each of the Noise Complaint’s four inputs are normalized (left to right), so that with nothing patched to a channel’s input it can be used as an attenuated mult, distributing up to four versions of one input signal and opening up myriad control possibilities, such as use of Channel One as a Macro control over the three other outputs. Channels 1-3 also have muting switches for performance-friendliness and preservation of settings.The Noise Complaint! has proven to be a very useful module for attenuation of all kinds, and adds a nice-feeling, sturdy set of performance controls to what is often a cluttered rack full of densely-packed jacks and tiny attenuation knobs.Features:• Four passive attenuator channels, three with mute switch• Inputs normalized A-D for use as an attenuated mult and more• Sturdy, performance-friendly hardware and designDIY-Kit-Type:THT-Kit-1.
