Voltage controlled polarizer / ring modulator

quadroPOL is a four-channel voltage controlled polarizer.

Its level potentiometers have a dead-zone in their center-position. Thus, it's easy to find the setting where the signal of is suppressed. Each channel works with a four-quadrant-multiplier which offers the possibility to use it as real ring-modulator.
