ABSTRACT:
A two conductor audio cable having no delay from end to end as a function of the frequency of audio signals conducted therethrough. There are a pair of conductor assemblies each comprising an elongated cylindrical core member of a flexible insulating material extending between the ends of the cable. A plurality of strands of an electrical conducting material are longitudinally disposed between the ends of the cable along the outer surface of the core member to define a cylindrical conductor which is, in essence, all "skin". The strands are electrically insulated from one another. A cylindrical support tube of a flexible insulating material is disposed over the core member and extends between the ends of the cable and is supported concentrically about and spaced from the core member by a helically wrapped support tube. A flexible electrical shield of braided material is disposed around the pair of support tubes and extends between the ends of the cable for holding the support tubes together in parallel relationship and for providing electrical shielding for the conducting strands therein. An external, shielded ground return capable of conducting higher levels of DC is also proved outside of the main braided shield.
