Conclusion -

Using the guidlines presented in this paper to select the proper type of audio cable for a project will optimize system performance and in most cases reduce the overall cabling expense. The chart below lists some common audio cable applications and expamples of recommended product types.

Definitions

Wire : metal in the form of a usually very flexible thread or slender rod

Cable : an assembly of electrical conductors insulated from each other but laid up together usually by being twisted around a central core.

Conductor : a material or object that permits an electric current to flow easily

Insulator : a material that is a poor conductor (as of electricity or heat)

Current : a flow of electric charge; also: the rate of such flow

Inductance : a : a property of an electric circuit by which an electromotive force is induced in it by a variation of current either in the circuit itself or in a neighboring circuit b: the measure of this property that is equal to the ratio of the induced electromotive force to the rate of change of the inducing current

Capacitance : a : the property of an electric nonconductor that permits the storage of energy as a result of the separation of charge that occurs when opposite surfaces of the nonconductor are maintained at a difference of potential b: the measure of this property that is equal to the ratio of the charge on either surface to the potential difference between the surfaces.

Balanced Line : a : an audio transmission line where the signal is applied differentially between two conductors, each of which has equal impedances to ground or common.

Impedance : a : the apparent opposition in an electrical circuit to the flow of an alternating current that is analogous to the actual electrical resistance to a direct current and that is the ratio of effective electromotive force to the effective current

That's all for the moment, folks. Thank for reading & visiting. Would like to wish "Gong Xi Fatt Choy" for those who celebrate Chinese New Year & Prosperity year ahead.
