Signal cable assembly

Abstract

A signal cable assembly comprising a pair of cables adapted to respectively carry the positive and negative audio signals between a power source and a load. Each cable consists of a first conductor formed by a plurality of bundles of wire strands twisted together to form a single conductor, and a second conductor in the form of a solid conductor having a diameter larger than the diameter of each wire strand. Insulation sleeves extend around the conductors for at least a portion of the length thereof.
