Abstract
Abstract An interconnection cable for audio frequency high fidelity applications, such as loudspeakers, is provided wherein a first wire and a second wire extend between a reference end and a terminal end, the second or auxiliary wire being divided into two serial segments by a single electrical discontinuity separating each segment, wherein each segment is conductively terminated at its respective end in a signal common or ground with the first wire, and wherein the electrical discontinuity is at between 9/16 and 23/32 of the distance from a reference end. Multiple interconnection cables may be assembled into balanced transmission lines for a signal path and a signal return. It is preferable that the reference end be at the signal source and the terminal end is at the signal load.
