Product Description

The science of AC power delivery is not a simple one; it demands focus, and the devil is in the details. In fact, the great 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 AudioQuest's utilities AC power a somewhat antiquated technology.

Where Alternating Current (AC) is concerned, were relying on a century-old technology created for incandescent lights and electric motorstechnology that was certainly never meant to power the sophisticated analog and digital circuits used in todays premium audio/video systems. To properly accom-modate the promise of todays ever-increasing bandwidth and dynamic range, AudioQuest must achieve extraordinarily low noise across a very wide range of frequencies.

Further, todays power amplifiers are being taxed for instantaneous peak-current demand, even when theyre driven at modest volumes. Although AudioQuest have seen a substantial increase in dynamics from much of their audio software, the loudspeakers they employ to reproduce them are often no more efficient than they were two to four decades ago. This places great demands on an amplifiers power supply, as well as the source AC power supplying it.

AudioQuest systems sensitive components need better alternating currenta fact that has resulted in a host of AC power conditioning, isolation transformer, regeneration amplifier, 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 AudioQuest's components. This noise couples into the signal circuitry as current noise and through AC ground, permanently distorting and/or masking the source signal.

Given that the stakes are so high, all sincere attempts to solve this problem must be applauded.

Once the audio/video signal is gone, its gone forever

For AudioQuest, honoring the source is never a matter of simply using premium audiophile-grade parts or relying on a proprietary technologycommon approaches within AudioQuest's community. 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?; and on and on. While AudioQuest, too, can brag about their many unique technologies, AudioQuest realize that true audio/video optimization is never a matter of any one secret or exotic circuit. When it comes to noise filtering for AC power, many approaches can yield meaningful results. However, these approaches may also impart ringing, current compression, and non-linear distortions that can render the cure worse than the disease!

The Niagara 5000 features AudioQuest's patented AC Ground-Noise Dissipation, the widest bandwidth-linearized AC filter in the industry, and their unique passive/active Transient Power Correction Circuit. Boasting an instantaneous current reservoir of over 90 amps peak, the Niagara 5000 is specifically designed for todays current-starved power amplifiers. Many AC power products featuring high-current outlets merely minimize current compression; the Niagara 5000 corrects it.

Though its easy to tout a given technology, its quite another thing to create a solution that is consistent, holistic, functional, and that honors verifiable science. Its not enough to reduce AC line noise and its associated distortions at just one octave, thus leaving vulnerable the adjacent octaves and octave partials to noise, resonant peaking, or insufficient noise reduction. Consistency is key. AudioQuest should never accept superior resolution in one octave, only to suffer from masking effects a half-octave away and ringing artifacts two octaves from there. This is the principal criterion for AudioQuests Low-Z Power Noise-Dissipation System.

The Niagara 5000 represents over 20 years of exhaustive research and proven AC power products designed for audiophiles, broadcast engineers, and professional-audio applications. Every conceivable detail has been addressed: In the Niagara 5000, youll find optimized radio-frequency lead directionality, capacitor run-in forming technologies developed by Jet Propulsion Laboratories and NASA, and AC inlet and outlet contacts with heavy silver plating over extreme-purity copper, assuring the tightest grip possible.

A great system is built from a solid foundation, and that foundation starts with power. With an AudioQuest Niagara 5000, youll experience for the first time the clarity, dimensionality, frequency extension, dynamic contrast, and grip your system has always been capable of deliveringif only the power had been right!

AudioQuest welcome you to experience the Niagara 5000 and hear firsthand the remarkable results of highly optimized power management: startlingly deep silences, stunning dynamic freedom, outstanding retrieval of ambience cues, and gorgeous delineation of instruments and musicians in space. Once youve experienced it, it may seem so elegant, so logical, and so obvious that you find yourself wondering why it hadnt been done before.

Features

NIAGARA 5000 COMMON-MODE NOISE DISSIPATION
Common-Mode Noise Dissipation: In excess of 30dB from 20kHz to 100MHz, linearized for dynamic (rising) line impedance with frequency (source) and 10 to 50 ohm load, system current dependent.

NIAGARA 5000 SURGE SUPPRESSION
Surge Suppression: Non-sacrificial (nothing to damage with repeated 6000V/3000A input surge tests, which is the maximum that can survive through a buildings AC electrical panel).

NIAGARA 5000 EXTREME VOLTAGE SHUTDOWN
Extreme Voltage Shutdown Voltage: 140VAC (will activate the main high-current relay to open within less than 0.25 second; automatically resets once the incoming power is within a safe range).
