The Niagara 3000 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 3000, 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.
The Niagara 3000 features AudioQuest’s patented AC Ground-Noise Dissipation, the widest bandwidth-linearized AC filter in the industry, and unique passive/active Transient Power Correction Circuit. Boasting an instantaneous current reservoir of over 55 amps peak, the Niagara 3000 is specifically designed for today’s current-starved power amplifiers. Many AC power products featuring “high-current outlets” merely minimize current compression; the Niagara 3000 corrects it.
- Transient Power Correction: 55 amps peak. Provides a current reservoir for any power amplifier (up to 25mS)
- Level-X Linear Noise-Dissipation Technology: More than 21 octaves differential-mode filtering (10kHz–1GHz in excess of 24dB reduction) with linear response, optimized for varying line and load impedance
- Patented Ground-Noise Dissipation (All outlets): 3 banks of direction-controlled ground-noise dissipation
- Non-Sacrificial Surge Protection: Withstands multiple AC surges and spikes up to 6000V/3000A without sustaining damage—sonically non-invasive
- Maximum RMS Input Current: 15 Amps (RMS)
- Outlets: Source (5); High-Current (2)
- Dimensions: 17.5″ W x 3.45″ H x 15.2″ D (2-RU Rack Mount Kit included)
- Weight: 28.9lbs. (US); 13.1kg.
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 our utilities’ AC power a somewhat 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 today’s 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 very 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 dynamics from much of our audio software, the loudspeakers we employ to reproduce them are often 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 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 our components. This noise couples into the signal circuitry as current noise and through AC ground, permanently distorting and/or masking the source signal.
Though it’s easy to tout a given technology, it’s quite another thing to create a solution that is consistent, holistic, functional, and that honours verifiable science. It’s 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. We 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 AudioQuest’s Low-Z Power Noise-Dissipation System.
Experience the Niagara 3000 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 you’ve experienced it, it may seem so elegant, so logical, and so obvious that you find yourself wondering why it hadn’t been done before.
