Low-Z / Noise-Dissipation 3-Pole AC Power Cable Solid Perfect-Surface Silver (PSS) Conductors Optimized For Source Components Ground Noise-Dissipation Technology (US Patent # 9,373,439) ZERO: No Characteristic Impedance Dielectric-Bias System with Radio Frequency Noise Trap Directionally Controlled Conductors Alternating Current (AC), is a far-from-perfect power source. AC power technology is well over a century old and was never designed to meet the exacting standards of today’s high resolution audio-video components. AC noise is present at the utility source, and is then exacerbated by radio frequency noise that is induced (picked up by the AC power cord) and coupled to the component power supplies and to circuit ground. This creates distortion and low-level signal losses via the “masking effect.” Most AC power cords and power conditioner-regenerators, though helpful to a point, are simply not up to the task.Note: AudioQuest Dragon/Source AC power cable is not appropriate for use with AC power conditioners, power regenerators, AC isolation transformers, AC battery back-up devices, as well as any power amplifier, powered sub-woofer, powered loudspeaker, powered receiver, or integrated amplifier (whether tube, solid state or digital switching). These products will require greater RMS and transient current capacity. In extreme instances, they could suffer diminished performance and/or present an electrical danger by exceeding the AudioQuest Dragon/Source AC power cable’s maximum current capacity. For those applications, we highly recommend selecting the AudioQuest’s Dragon/High-Current AC power cable. SOLID PERFECT-SURFACE SILVER (PSS) CONDUCTORS Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest's highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers. GND (GROUND-NOISE DISSIPATION) AC Ground wires provide protection from current-wiring faults, but they also act as antennas. Thus, they are subject to induced radio-frequency (RF) noise. This RF noise bypasses component power supplies and is typically coupled directly into a system’s most sensitive audio/video circuits. AudioQuest’s patented Ground-Noise Dissipation (GND) greatly reduces this distortion, yielding unprecedented levels of noise dissipation across the widest bandwidth (range) of radio frequencies possible. Our unique circuit topology utilizes a common-mode phase-cancelling array, in concert with proprietary dielectric materials which provide additional differential linear filtering. (US Patent # 9,373,439) DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio-frequency noise will not be induced into the signal conductors from the DBS field elements. (DBS, US Pat #s 7,126,055 & 7,872,195 B1) DIRECTIONALITY All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality. For most models of AQ cable, the arrows not only indicate the direction that optimizes metal-directionality as part of Noise-Dissipation, but also indicates non-symmetrical attachment of shield and GND in order to optimize full-system performance.
