WMD SPO Scaler Polarizer Offset Generator

Great condition, fully tested, incredibly useful. Comes with bus cable. 

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).

• Incorporates up to two inputs into a single scaler/offset generator
• Shifts signals into +/- voltage region
• Applied S.P.O. interfaces audio or CV
