Quad Comparator


It’s a simple quad comparator based around the LM339.

It will take your Voltages and turn them into Logic On.

When your signal is higher than the threshold the Gate goes high and the NOT Gate goes low.
When your signal is lower than the threshold the NOT gate goes high and the Gate goes low.

You can set the threshold anywhere from about -10V to +10V.

Input 1 is buffered then normalled to JackSwitches 2->4. So you could send an LFO in to Input 1, set different thresholds for all the inputs and have all the gates/NOT Gates fire at different points from the same LFO.
