You can "see" this mechanically.
Turn the knob fully anticlockwise. The wiper will now be positioned at the stop next to Input. Wiper taps off maximum signal level (=loud).
Turn the pot fully clockwise till the wiper hits the Common stop. The wiper now taps off a near ground signal level (=quiet)
is this correct?
