Niagara 5000AP Features

¡ 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 16 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 a simple one; 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.

The Niagara 5000AP uses both our patented AC Ground Noise-Dissipation System and the widest bandwidth-

linearized noise-dissipation circuit in the industry. Our unique passive/active Transient Power Correction Circuit
