Audio CableThe requirements on high-quality audio cables are fundamentally different from those on loudspeaker cables. The signals they carry are in the Millivolt region, and the currents that flow are relatively low.
Audio Triax is available terminating in four different connectors: Cinch leads with rhodium-plated RCA plugs; aerial leads with rhodium-plated co-ax plugs and rhodium-plated F-plugs; and digital leads terminating in BNC plugs. In all cases the plug housings are precision-machined from high-quality aluminium, and finished by hard anodising. The resultant surfaces are extremely tough and robust.
Where two devices are to be linked by an XLR connection, the basic requirement is for a cable with two signal conductors, one wire is in phase with respect to the source signal, the other wire is reversed in polarity, and at least one separate earth conductor. This principle makes it possible to cancel interference and noise by subtracting the two signals and also permits the use of very long cables. These are typically required for systems which utilise active speakers, or whose output stages are located immediately adjacent to the speaker cabinets. Audio Quad even features additional earth and control conductors.
When the aim is superior sound quality, the requirements on high-quality XLR cables correspond exactly to those of Cinch cables, and the design of the cable must therefore be equally refined and sophisticated. The complex construction and geometry of Audio Duo cable, incorporating different insulators, shielding measures and materials, ensures very low capacitance and transmission characteristics which are frequency-independent.
