At its fully clockwise (on) position, the control passes 100% signal level through. At the fully counter-clockwise (off) position, the control completely mutes the signal. This is an infinite control, meaning that there are no "steps" between off and on, the sound level smoothly increases as you turn the knob. This control has an audio taper, meaning that the increase in sound level seems proportionate with the amount turned, at the low end and at the high end.
Note that this is a passive control. It requires no power supply and thus it cannot amplify the signal. Max in is max out. For a nice companion piece when amplification is needed, see our LITTLE AMP. (AT-LITAMP)
