    What does volume do?
    When you turn that volume knob, what's actually happening? The amount of power given to the amp changes, or what?

    Skeptic can probably give you a more indepth answer, but in essence the volume controls the amount of current going to the amplifier.

    A volume control is basically a voltage divider.

    It controls the amount of voltage that is passed from the preamp section to the power amp section.

    Since voltage is a component of power (P=V*I or P=V*V/R), power is also controlled, by the square of the signal voltage (for a given Rspeaker impedance).

    You can think of volume control as a faucet that controls the output of a water reserve.

    Hi F1,

    Thanks for digging that up. As there more and more posts on the board, there's so much more value added to being a member.
