A Question About Volume Controls Types

One control is entirely analog and that is what you are adjusting.
The other is digitally controlled, and remembers what its setting was last time it was operated. The control itself is simply a counter wheel and can spin as much as you like. When on, the circuit counts the notches that have gone by as you advance the control and makes the change in volume.

Thanks for all the answers!

@oddiofyl This amp sound so much better than the Counterpoint SA3.1 preamp/Adcom GFA555 amp combo that I had been using for over 30 years. I still have a tube front end with a solid state output stage like before, but this integrated amp is a real step up for me.

I have one more question if you don’t mind; are there any advantages with one type of volume control over the other?

No input for the OP’s post, it reminded me of something. Lil humor.

Raised my son always use the remote never use the components buttons. Years later he brought that subject up, it didn't dawn on him til he had kids...I grinned.

Maybe somebody else can tell if there's an advantage with one type of volume control over another?

Well, with the regular type volume control, it's probably a potentiometer which is basically a variable resistor and typically these continuously contact a resistive plate, which can wear out and become statick-y over time. The other type is a stepped attenuator, with discrete contact positions which attenuate the signal using a set of resistors. These contacts are discrete steps so at any position the knob is connected to two contacts, one at the input...then the signal passing through a set of resistors, and going to the output contact position. The possibility of wear and tear is less.
