US 2019/0356986 A1 · Loudspeaker Impedance Matching Device for Non-Permanent Applications

Abstract

An impedance matching device including a transformer having an input side and an output side, wherein the input side includes a first coil having a first impedance, a second coil having a second impedance, and a third coil having a third impedance. An input power connector is electrically connected to the input side of the transformer, and a pass through output power connector is electrically connected to the input side of the transformer, and the pass through output connector also is electrically connected in parallel to the input power connector. A speaker output connector having four electrical contacts is included, wherein a first pair of the four electrical contacts is connected electrically to the first coil, and a second pair of the four electrical contacts is connected electrically to the second coil.
