This circuit is known for decades and allows gain setting over a bigger level range than with a passive pot provideing a good noise performance as well. You can find it in analogue mixing consoles.
Nothing esoteric with it.
But the potentiometer they use looks like some el cheapo low quality stuff, anything else but high-end.

It's just a unity gain buffer behind the volume control. It's as simple as a wikipedia circuit. Provide local bypassing on the board. Capacitor couple what you need to for your circuit. You can even configure it for gain with the addition of 4 more resistors.
Que coño has querido decir aqui amigo mio?!!!Translation; WTF were you trying to say here my friend.
I love conundrums but this one was too much for my intellect.
It just varies the gain of the active circuit. It's very useful.
This is the issue with the circuit. If the potentiometer displays any intermittent operation, then the circuit goes nuts. Any scratchiness is amplified in a nasty way. Any nonlinearities in the potentiometer are amplified.
Fitero, I meant that as someone has said that the device can operate, will set to work. If I make a mistake it's because I have not mastered English well and therefore use the Google translator. Or because I write from a mobile phone, which leads spelling errors. I apologize, but I'm not a new user, I have intervened on many issues and no one has made a mistake taunts. Greetings.
