The Attenumixer is a 4hp 3 channel Passive Attenuator and Mixer Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.
Each channel is normalled to the sum(VI) so it can be used as a 2 channel mixer and 1 channel attenuator, or a 3 channel mixer, or as 3 separate attenuators. Normalization to the sum is broken by inserting a jack into the outs of channels I-III. The Attenumixer works well with both cv and audio, although the potentiometers have a linear response. Since the module is passive there will be signal loss at the sum out.
The module comes with a double sided panel one side is classic with the traditional graphics and the reverse side is soulless with no graphics, only text.
