passive attenuator and multiple
The CubuSynth 6xLevel module is a 8hp 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 white lines on the Front panel mark the normalisation routing.
