    I apologise for resurrecting such an old thread. I've built a controller to the same specs as what HxCxK has on that circuit diagram, however I'm running into a few issues.

    Bass control doesn't seem to be working

    There is a constant humming/buzzing on the subwoofer (Something isn't earthed properly and I think it's from the AC line). It gets louder when I touch the (insulated) SLINE (pin 1) wire.

    The only one thing I haven't done is ground Pin 3 to the actual chassis of the subwoofer.

    I've also compared it to jseaber's diagram and I've noticed a massive difference in the resistor values. How much of a difference does this make, I'm wondering?

    Any help would be greatly appreciated.
