Bipolar Mixer

Configurable attenuverting mixer

The module contains 4 x 2-channel mixer sections. When the output of a section is not patched, it's linked and summed to the next section. So depending on which outputs are patched, the module can be four 2-ch mixers, two 4-ch mixers, one 8-ch mixer, one 2-ch + one 6-ch mixer, two 2-ch + one 4-ch mixer, etc.. The module does not have any DC-blocking, so works equally well for audio and CV.

Each input has an attenuverter knob, giving zero in the center, inverting (-1x gain) to the full left and normal (1x gain) to the full right.

The first input of each 2-ch section is normalled to a voltage reference, which makes the knob into a +/- 5V offset control. So each section can function as an individual offset & attenuverter.
