Reduce AC Line Noise, Masking Effects, and Distortions at All Octaves: AudioQuest Niagara 5000 Low-Z Power Noise-Dissipation System Improves Nearly All Aspects of Music Playback

Sonic consistency: That's the basis behind the AudioQuest Niagara 5000 Low-Z Power Noise-Dissipation System. Specifically, reducing AC line noise, masking effects, and associated distortions not just at one octave but at all adjacent octaves. Delivering more than 90A peak instantaneous current for power-starved amplifiers, the 12-outlet Niagara 5000 power-management system incorporates many of the reference-class features from its big brother – including surge suppression, extreme-voltage shutdown, common-mode noise dissipation, and NRG Series inlets and outlets. Just wait until you hear the dynamic freedom, ambient cues, deep-space silences, instrumental separation, and fully formed imaging once Niagara 5000 enters your setup. 100% Music Direct Money-Back Guaranteed.

A Consistent, Holistic, and Science-Based Power Solution: Every Detail Addressed

While it's easy to tout a given technology, it's quite another to create a solution that is consistent, holistic, functional – and that honors verifiable science. It's not enough to reduce AC line noise and its associated distortions at just one octave, leaving vulnerable the adjacent octaves and octave partials to noise, resonant peaking, or insufficient noise reduction. Listeners 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. These principles represent the criterion for AudioQuest's Low-Z Power Noise-Dissipation System. In Niagara 5000, every conceivable detail is addressed. You'll 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 Niagara 5000, you'll experience for the first time the clarity, dimensionality, frequency extension, dynamic contrast, and grip your system has always been capable of delivering – if only the power had been right!

Your System Needs Low Noise to Take Advantage of Increasing Dynamics and Bandwidth

The exponential rise 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 utilities' AC power a somewhat-antiquated technology. Where Alternating Current (AC) is concerned, we rely on a century-old technology created for incandescent lights and electric motors – technology never meant to power the sophisticated analog and digital circuits used in today's premium audio/video systems. To properly accommodate the promise of today's ever-increasing bandwidth and dynamic range, you must achieve extraordinarily low noise across a very wide range of frequencies. Although we have seen a substantial increase in dynamics from audio software, loudspeakers are often no more efficient than they were two decades ago. This places great demands on an amplifier's power supply, as well as the source AC power supplying it.

Designed for Current-Starved Amplifiers: Niagara 5000 Corrects Current Compression

Your system's sensitive components need better alternating current – a fact that has resulted in a host of AC power conditioning, isolation transformer, regeneration amplifier, and battery back-up system topologies. Via differential sample tests and spectrum analysis, engineers have determined that one 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. This noise couples into the signal circuitry as current noise, permanently distorting and/or masking the source signal. 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.
Features & Technical:
  • Surge Suppression: Non-sacrificial (nothing to damage with repeated 6000V/3000A input surge tests, which is the maximum that can survive through a building’s AC electrical panel)
  • 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)
  • 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.
  • Input Current Maximum Capacity: 20 amps RMS (total)
  • Ultra-Linear Noise-Dissipation System AC Power Outlet Banks: 4 Isolated groups – total (bank three through six)
  • Number of AC Outlets: 12 (4 High Current/Transient Power Correction; 8 Ultra-Linear Noise Dissipation System Power)
  • Power Consumption: Typically, less than 0.25 amps at 120VAC input, or with the power correction switched to Standby setting. (This is dependent on a reactive vector load. For more info, see “Operation and Continuous Use: Rear-Panel Power Correction Switch – Niagara 5000 current draw.”)
  • Dimensions: 17.5” W x 5.24” H x 17.2” D (3-RU rack-mounting ears, optional)
  • Weight: 38 lbs.

  • Note: Niagara Noise-Dissipations Systems do not ship with an AC power cable. This gives customers the opportunity to select a cable of the desired length and best possible performance. An appropriate 16-to-20-amp-rated (depending on regional voltage requirements) AC power cable, with an IEC-C19 female end connector and a grounded male plug, must be connected to the Niagara’s AC inlet (IEC-C20) connector. Niagara Noise-Dissipation Systems will function properly with any AC cable that meets these requirements. However, for the best possible results, taking full advantage of AudioQuest’s patented Ground-Noise Dissipation, we highly recommend any AudioQuest NRG Series 16-to-20-amp-rated AC cable.
