S.P.O. is a polarizing scaler and offset generator.
Up to two inputs can be summed into a single scaler/offset generator. The offset generator provides a DC voltage source for shifting signals into the positive or negative voltage region. The scaler provides a means of attenuating and polarizing (inverting) the applied signal. S.P.O. works with audio and control voltages (CV).
