Notice how the output CV (magenta) is now stepped, and only changes when the audio passes
through zero. Also, the output waveform no longer has the click at the start, since it remains at
zero until the frst zero-crossing.
For an even more example consider the images below, now using a simple gate pulse as the CV
input:
On the left (without zero-cross detection), note the random clicks that will occur at the start and
end of each burst. On the right (with zero-cross detection), note how each burst begins and ends
cleanly at zero.
Calibration
A trim pot (marked RV5) on the PCB allows for adjusting the VCA gain. Persephone is factory-
calibrated so that the module gives unity gain with Bias set to 10, Pre set to 0, and Post set to 10.
