AudioQuest Niagara 1000 Power Conditioner

Eliminating noise without limiting current

The key to the Niagara 1000's performance is its wideband linearity, designed to avoid the current compression and distortion that typically characterize less sophisticated AC power conditioners. The Niagara 1000's "secret sauce" is AudioQuest's patented Ground Noise-Dissipation technology.

Why is dissipating ground noise so critical?

A surprising amount of AC noise can be traced to the ground lead. Because the electrical service depends on this lead primarily for safety, there are very few ways to effectively reduce ground noise. Compounding the issue is the fact that many audio circuits depend on the AC ground lead to ensure an electrical ground reference for minimal system hum.

The ground lead: an often-ignored source of RF noise

The typical 3-prong AC connector has three wires: line, neutral, and ground. In contrast to the line and neutral leads, the ground lead bypasses the component power supply and makes a direct connection to many critical analog and digital circuits, introducing a torrent of RF (radio frequency) noise. This noise is spread across a wide range of frequencies and impedances, which is why simple filters are only partially effective.

And even when the noise itself isn't audible it can mask or distort low-level audio signals, resulting in grainy sound and a constricted soundstage.

AudioQuest diverts the noise

AudioQuest's patented circuit combines ultra-low impedance (at 50-60Hz) induction with proper lead orientation for optimal noise dissipation. The noise currents that would otherwise result in audible distortion are instead directed away from the sensitive audio circuits for sound that is cleaner, clearer, and more dynamic and relaxed.

Comprehensive surge protection for your system

The Niagara 1000 has six AC outlets to protect your entire A/V system. There's one high-current outlet that will protect your receiver or power amp without ever limiting the AC current it needs. The other five outlets feature multi-level noise filtering to remove AC line noise and ground noise.

The Niagara 1000's non-sacrificial surge protection can withstand multiple AC surges and spikes up to 6000 volts or 3000 amps — the maximum that can make it through a home or office electrical panel. Lesser units sacrifice themselves in order to suppress significant surges. The Niagara 1000 is unaffected by such surges, surviving to do its job over and over again as necessary.
