Quad Gate Inverter
This 2HP Eurorack module will invert 4 separate gate signals. The outputs will always be either 0V or 5V. The positive-going threshold for each input is 1.5V and the negative-going threshold is 1V. This module has built-in over-under voltage protection so it is able to handle anything -12V to +12V at the inputs and at the outputs without damage.
