¡ Transient Power Correction provides power amplifiers a current reservoir of over 90 amps peak
(up to 25mS)
¡ Patented Ground-Noise Dissipation System yields lower distortion and greater resolution from
audio, video, and digital components with grounded AC cords/circuits
¡ Level-X Ultra-Linear Noise-Dissipation Technology: More than 23 octaves differential-mode
filtering (3kHz-1GHz in excess of 24dB reduction) and 20 octaves common-mode filtering (20kHz-
100MHz in excess of 30dB reduction) with linear response, optimized for varying line and load
impedance
¡ 12 Low-Z NRG Series AC Power outlets: 4 High-Current Low-Z Power; 8 Level-X Ultra-Linear
Filtered Power (source components) Outlets feature thick direct-silver plating over beryllium
copper. This assures the most efficient dissipation of induced radio frequency noise possible.
Introduction
The science of AC power is not simple; it demands focus, and the devil is in the details. In fact, the mammoth
increase in airborne and AC-line-transmitted radio signals, combined with overtaxed utility lines and the ever-
increasing demands from high-definition audio/video components, has rendered our utilities' AC power an
antiquated technology.
Where Alternating Current (AC) is concerned, we're relying on a century-old technology created for incandescent
lights and electric motors—technology that was certainly never meant to power the sophisticated analog and
digital circuits used in premium audio/video systems. To properly accommodate the promise of today's ever-
increasing bandwidth and dynamic range, we must achieve extraordinarily low noise across a wide range of
frequencies.
Further, today's power amplifiers are being taxed for instantaneous peak-current demand, even when they're
driven at modest volumes. Although we have seen a substantial increase in both dynamics and bass content from
our audio software, the loudspeakers we employ to reproduce them are no more efficient than they were two
to four decades ago. This places great demands on an amplifier's power supply, as well as the source AC power
supplying it.
Our systems' sensitive components need better alternating current—a fact that has resulted in a host of AC power
conditioning, isolation transformers, regeneration amplifiers, and battery back-up system topologies. Through
differential sample tests and spectrum analysis, it can be proven that up to a third of a high-resolution (low-level)
audio signal can be lost, masked, or highly distorted by the vast levels of noise riding along the AC power lines
that feed our components. This noise couples into the signal circuitry as current noise and through AC ground,
permanently distorting and/or masking the source signal.
All sincere attempts to solve this problem must be applauded since once the audio/video signal is gone, it's
gone forever...
For AudioQuest, honoring the source is never a matter of simply using premium "audiophile-grade parts" or
relying on a proprietary technology—common approaches used within the audiophile market. For years, we
have all been witness to the same, seemingly endless audiophile debates: Valves versus transistors. Analog versus
digital. Can cables really make a difference? The debates go on and on. While we, too, can brag about our many
unique technologies, we realize that true audio/video optimization is never a matter of any one secret or exotic
circuit. When it comes to noise dissipation for AC power, many approaches can yield meaningful results. However,
they may also impart ringing, current compression, and non-linear distortions that are worse than the disease.
