The SISM is a 4-channel voltage manipulator that can scale, invert, attenuate, shift (dc offset), mix, split, and slice your CV and audio signals.

A plethora of red and blue LEDs (14) show exactly what each channel and output jack is doing: red = negative voltage, blue = positive.

Each channel is independent and has an input jack, output jack, a knob for attenuating/inverting (Scale), and a knob for applying positive or negative DC offset

Note: This is a used module. It may exhibit minor signs of wear such as rack rash but is fully functional. This module will include M3 screws, ribbon cable, and a box, but not the original box.
