Short summary

A high-current mains power cable for power amplifiers, which draw large reserves of transient current. The Thunder reduces the AC noise and RF interference that mask fine detail, supplying clean power for your amplifier’s dynamics.

Key info

  • Entry point to the high-current range
  • Stabilises supply during dynamic passages

Description

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.

Low-Z / Noise-Dissipation 3-Pole AC Power Cable

  • Solid Perfect-Surface Copper (PSC) Long-Grain Copper (LGC) Conductors
  • Uncompressed High-Current Transfer
  • Ground Noise-Dissipation Technology (US Patent # 9,373,439)
  • ZERO (No) Characteristic Impedance (50Hz – 1MHz)
  • 72VDC Dielectric-Bias System (US Patent #7,126,055)
  • Directionally Controlled Conductors

GND-Tech (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.

High Purity Conductors – Long-Grain Copper (LGC) and Perfect-Surface Copper (PSC)

A carefully finessed combination of solid high-purity Long-Grain Copper (LGC) and high-purity Perfect-Surface Copper (PSC) conductors prevent strand interaction, a major source of ear fatiguing transient intermodulation distortion. LGC allows a smoother and clearer sound than standard OFHC (Oxygen-Free-High-Conductivity) copper. The astonishingly smooth and pure Perfect-Surface Copper further eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other premium coppers.

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.

Uncompressed High (Variable) Current Transfer – Thunder

With current capacity of 20 amps RMS @ 125VAC 50/60Hz (16 amps RMS @ 220-240VA 50/60Hz), Thunder/High (Variable) Current can withstand current transient peaks many times its continuous (average) RMS rating. This makes Thunder/High (Variable) Current ideally suited for a wide assortment of AC power conditioners, power regenerators, AC isolation transformers, and AC battery back-up devices, as well as any power amplifier, powered subwoofer, powered loudspeaker, powered receiver, or integrated amplifier.
