Each output is a buffered negative version of the input. e.g. if an input is fed a 2v cv signal, the output will be a -2v signal.All outputs are normalled to the inverter input below it.
inverts audio inputs and shifts their phase by 180 degrees.This is not used for inverting gates. For this you need a logic inverter as found on the Plog module.More Info: Quad Inverter
