A PAC LC-1 is a potentiometer with a variable resistor, the amount of current flowing through can be varied by adjusting the knob. So turning the knob full + = full current = full volume, whereas full - = no current = no volume. It is the exact same thing as your sliding/knob/dimmer light switch at home.
