Given the extremely fragile nature of the phono signal, every effort must be pursued in order to preserve the integrity of that signal throughout the signal path. One area where the signal can suffer significant damage and loss is in the Phono Cable. Cartridge output levels are quite low, typically in the 3-5 millivolt range and often as low as 100 mircovolts. Audience's use of continuous cast High-Purity Copper as well as Low Loss Cable Geometry preserves the purity of this low level signal. Consumers often choose a Phono Cable based upon brand recognition alone. However, such a choice can inadvertently compromise a phono playback system due to mismatched impedance characteristics between Cartridge and Cable.
Audience has conducted considerable research into the electrical characteristics of Phono Cables and has concluded that a single Cable cannot possibly serve as an optimal Tonearm Phono Stage interface. The different internal electrical characteristics of Phono Cartridges make choosing a Cable designed to preserve and enhance those characteristics an all important issue. By choosing the wrong Cable you can lose precious low level detail information that is essential to overall sonic presentation.
For these reasons, Audience offers Vinyl Lovers a choice of three impedance-matched Phono Cables. Each model is designed to carefully optimize the electrical characteristics of the Cartridge to the Cable and to preserve signal flow to the Phono Stage without detrimental influences as follows:
Au24e Low Z MC Phono Cable - for Moving Coil Cartridges with internal resistance up to 30 ohms.
Au24e High Z MC Phono Cable - for Moving Coil Cartridges with internal resistance between 30 and 100 ohms.
Au24e MC/MI/MM Phono Cable - for all cartridges with internal resistance above 100 ohms which includes Moving Coil Cartidges rated at 47k ohms and most Moving Magnet or Moving Iron models.
