Abstract: A plug for connection to an RCA or phono type socket wherein a signal pin (15) is frictionally located within the bore of said socket and a pin-like return conductor (16) is adapted to make contact with the socket casing. The spacing (17) between the signal pin and return conductor is by means of a non-conductive plastic polymer or similar material, such material also assisting to engage the return conductor against the outside casing of the RCA socket. By reducing the amount of conductive metal material used in the return conductor of a typical RCA plug i.e. by using a pin-like return conductor rather than a cylindrical conductive band and associated support body, the present invention reduces inductive, capacitive and eddy current distortion and offers improved signal transmission.

Abstract: A signal carrying cable in which the return, negative or cold conductor is greater in overall cross sectional area and mass than the signal, positive or hot conductor, based on a specific ratio that balances the flow of electrons, enhances electron movement and as a result improves signal transmission. The ratio is based firstly on the cross sectional area of each signal core/s in relation to each return core/s, and secondly on the diameter or perimeter of each signal strand in relation to each return strand. The ratio works effectively whether there are one or more strands in each conductor. For cables where the diameter or perimeter of each strand is the same for both signal and return, the ratio is based on cross sectional area only. Cables can comprise conductor strands other than round i.e. square, flat, rectangular, tubular etc.
