1. An audio frequency signal transmission line having an input impedance for transmitting audio frequency signals from a source of audio signals to a load comprising:
- a first and second continuous electrical conductor having no discrete resistive, capacitive or inductive components located between the ends thereof; and
means for providing a capacitance coupled in parallel with at least one of said conductors such that a first and a second node at which the input impedance of said line changes from being an inductive impedance to a capacitive impedance and from a capacitive impedance to an inductive impedance, respectively, are located substantially outside of the audio frequency spectrum.

Abstract
In an audio signal transmission system having a source of audio signals and a load coupled thereto by means of a first and second transmission line, a discrete capacitor is coupled in parallel with one or both of the transmission lines. The magnitude of the capacitor is as large as stable operation of the amplifier to which it is connected will permit.
