Voltage for the signal? What does that mean? Electricity isn't measured in purpose.Gain is the voltage of the signal. Volume is the voltage for the signal.
Gain is a characteristic of a circuit. You aren't adjusting the circuit's gain that simply. You are adjusting the input voltage that reaches the amplifier circuit, which results in adjusting the output, which causes the audible volume to change. Exactly what every other volume knob does. It does the same thing as "bass knobs" inline with your signal cables.
