    Question hardware volume control

    How would I go about making a hardware volume control? I'm using a SB Live and all four channels. Before the sound get inputed to the amp I need a hardware volume control. I want to make one knob controling all four channels volume. Is there a POT that contols for items? How do I use the POT, ie which wire goes where? What type of POT do I need. I want to be able to mount the knob in-dash or console. Any suggestion?

    There is a small, 5 pin header on the sblive that you can hook up momentary switches to to control the volume. Lemme go find some more info.

    I'm planning on doing this for my next project, so I dug up a little more info. I took a couple of pictures of my SBLive:

    I belive a switch between the top and the bottom would be volume up, and a switch between the middle and bottom would be volume down.

    Hope this helps you.

    use a poteniometer (it is basically a variable resistor)... wire it so that it has an input and output and u can just connect it between your existing wires with out cutting them

    Any type of poteniometer? Do I need 1K, 10K?I was thinking about using 4 like the one below. Then just stacking the four on top of each other and put a rod in the hole.

    im staying away from the soundblaster live and going with a hercules 5.1 with upfront bay contols and rear rca ouputs, i beleive they make a model with hardware volume built into the bay, i just have to see if it controls the front bay outputs or the rca rear outputs.
