Moon Modular - 502 S Simple VCA

"Simple" Dual VCA with some tricks.

The M502 S Simple VCA makes your job easy, but it's not necessarily simple.

Three potentiometers are used to adjust the response and the characteristic curve of the two VCAs and a switch is used to select between AC and DC mode for audio or CV modulations.

Both VCAs have their own input and output jacks for audio signals and their own CV inputs for amplitude modulation. Audio input 1 and CV input 1 are each normalized to inputs 2 to simplify mono to stereo effects and the common control of the two VCAs via a CV input.
