Offset / Attunuverter
A Eurorack attenuverter and offset generator.
The top knob attenuates or inverts the incoming signal. Clockwise from the 12 o’clock position the output signal is increased in phase with the input. Counter clockwise the signal level is also increased but inverted.
The offset control adds a DC offset to the signal. Positive clockwise from the centre position, negative in opposite direction.
The module is designed for control voltages but also works with audio.
With nothing plugged into the input a variable control voltage is available at the output controlled by the offset knob.
