1. An impedance matching device, comprising:

  • a transformer having an input side, wherein the input side includes a first input having a first input impedance, a second input having a second input impedance, and a third input having a third input impedance and an output side, wherein the output side includes a first output having a first output impedance, a second output having a second output impedance, and a common ground output;

    an input connector electrically connected to the input side of the transformer;

    a pass-through output connector electrically connected to the input side of the transformer, wherein the pass-through output connector also is connected electrically to the input connector; and

    a speaker output connector having four electrical contacts, wherein a first pair of the four electrical contacts is connected electrically to the first output, and a second pair of the four electrical contacts is connected electrically to the second output.
