I bought this volume sub/treble control unit. I have no idea what the two cables on the back are for. One looks like a out audio cable from computer, I think. But there's a 5~pin din. Are these speaker line outlets? Surround sound? I guess my question is "would you be so kind and share with me and the world the (SFX) pinout". I'd be most greatful and your biggest fan. Thank you MTB
