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.” Further, power amplifiers can require immense reserves of transient current for their power supplies to react to and then stabilize during dynamic audio passages. Most AC power cords and power conditioner-regenerators, though helpful to a point, are simply not up to the task.
Power amplifiers present a real challenge for any AC power source, as the transient current requirements (though short in duration) can be many times that of the average (RMS) current consumption. Power amplifiers are also unique from all other components in that the current draw is dynamic, not constant, and it changes with volume and audio signal content. Though many AC power cords may feature low DC resistance to allow for some of this requirement, the characteristic impedance of the AC cable is equally responsible for assuring uncompromised performance. Many premium AC cords constrict or compress the audio transient as their characteristic impedance restricts the transient current.
RF/ND-Tech (Patented Radio-Frequency Ground-Noise Dissipation) Minimizes Circuit Misbehavior by Cancelling Induced RF Noise
US Patent # 8,988,168. AC Ground wires may provide protection from an electrical short circuit, but they also act as an antenna. 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 RF/ND-Tech 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-canceling array, in concert with proprietary dielectric materials which provide additional differential linear filtering.
High Purity Conductors – Perfect-Surface Copper (PSC) and Perfect-Surface Copper + (PSC+)
A carefully finessed combination of solid high-purity Perfect-Surface Copper (PSC) and extreme high-purity Perfect-Surface Copper + (PSC+) conductors to prevent strand interaction, a major source of ear fatiguing transient intermodulation distortion. The astonishingly smooth and pure Perfect-Surface Copper eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N, and other premium coppers. The superior purity of PSC+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor.
Uncompressed High (Variable) Current Transfer – Tornado
With a current capacity of 20 amps RMS @ 125VAC 50/60Hz (16 amps RMS @ 220-240VA 50/60Hz), Tornado/High ( Variable) Current can withstand current transient peaks many times its continuous (average) RMS rating. This makes Tornado/High (Variable) Current ideally suited for a wide assortment of AC power conditioners, power regenerators, AC isolation transformers, and AC battery backup devices, as well as any power amplifier, powered subwoofer, powered loudspeaker, powered receiver, or integrated amplifier.
72v Dielectric-Bias System with Level-X Radio-Frequency Trap (DBS)
All insulation is also a dielectric whose electrical properties affect the integrity of the signal. When the insulation is unbiased, dielectric-involvement (absorption and non-linear release of energy back into the signal flow) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a significant problem for very time-sensitive multi-octave audio. AudioQuest’s multi-patented DBS creates a strong, stable electrostatic field that saturates and polarizes (organizes) the molecules of the insulation. This minimizes the nonlinear time delays, resulting in clearer sound emerging from a “blacker” background. The Level-X RF Trap (a technology developed for AudioQuest’s Niagara Series of power products) in the DBS battery pack “pulls” RF Noise out of the cable, preventing RF from infiltrating the electronics. DBS Pack batteries last about 10 years. Use the test button to verify the condition.
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 indicate non-symmetrical attachment of shield and GND in order to optimize full-system performance.
