Yet, for the discriminating listener, many power conditioners can make an audio\/video system perform far worse.\u003c\/p\u003e\n\u003cp\u003eYes, a home or building may have dimming lights or an occasional brown-out, and the utilities’ AC sine wave is always far from perfect. However, where incoming power is concerned, there are two reasons an audio\/video system does not perform up to its full potential:\u003cbr\u003e1) The current transients that supply the power amplifier are compressed, and\u003cbr\u003e2) The ever-increasing levels of radio-frequency noise are masking (covering up) the system’s low-level signal content.\u003c\/p\u003e\n\u003cp\u003eWhen compared to or measured against a Niagara Low-Z Power Noise-Dissipation System, a simple power bar or a dedicated AC wall outlet can lose up to a third of the low-level audio information that contain much of a recording’s harmonics, imaging, high frequencies, and bottom-end grip—\u003ci\u003eand once that information is gone, it’s gone forever\u003c\/i\u003e.\u003c\/p\u003e\n\u003cp\u003eThe products in AudioQuest’s Niagara Series are meticulously handcrafted, and their technologies are unique amongst all power products—whether they’re isolation transformers, AC regenerators, battery backup devices, re-clocking devices, or other types. Far surpassing most other technologies that cover only a narrow range of noise frequencies and do nothing to address the increasingly prevalent noise on AC ground, Niagara’s Level-X and patented Ground-Noise Dissipation (GND) Technology work evenly, or linearly, across a far wider range of induced noise frequencies.\u003c\/p\u003e\n\u003cp\u003eAdditionally, Niagaras 3000, 5000, and 7000 feature Transient Power Correction, which supplies a current reservoir to greatly bolster the performance of any power amplifier.\u003c\/p\u003e\n\u003cp\u003eWith an AudioQuest Niagara Low-Z Power Noise-Dissipation System, music lovers can finally experience the clarity, dimensionality, frequency extension, dynamic contrast, and grip their A\/V systems have been capable of delivering—if only the power had been right!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNiagara Noise-Dissipation Systems do not ship with an AC cable. Why?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe cable that feeds any power product is the most important AC cable in the audio\/video system. For any power product to maximize its ability to dissipate noise, the attached AC cables must be Direction-Controlled to drain induced radio-frequency noise. AudioQuest AC cables include ZERO-Tech for uncompressed current transfer and optimal Noise-Dissipation. Further, our patented GND-Tech (Ground-Noise Dissipation) pulls RF noise out of any product it’s attached to.\u003c\/p\u003e\n\u003cp\u003eWhen partnered with a Niagara power product, our Direction-Controlled AC cables create a complete Noise-Dissipation System, ensuring the most effective and efficient dissipation of RF noise.\u003c\/p\u003e\n\u003cp\u003eWe allow our customers to select the appropriate length of cable for their systems and to decide how completely they’d like to optimize their Niagaras.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e  \u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"bullet\"\u003ePatented Dielectric-Biased Symmetrical Power Isolation Transformers: 2 for source component outlet banks\u003c\/li\u003e\n\u003cli class=\"bullet\"\u003eTransient Power Correction: 90 amps peak.
