found this, but it would mean one chip per channel, are there 8 or is
there really only one for all?
...I've reworked those for years. Poor man's plug in automation done
cleanly with MDAC's....

All the chatter around is about how it is passive, so it has “infinite” headroom, 0% distortion, 0% gain. I got one recently for a low price. I looked inside, eager to know the trick…. Vactrols? Motorized pots? something I don’t even know about? Inside the is a big chip 28pins or something with the label scratched off. Does anyone know what is actually going on in this thing? Is that an 8 channel digitally controlled pot? Just curious.
