What You Need to Know
Not a Power Strip—A Noise-Dissipation System
Everything in your system starts with the power from your wall—and that power is polluted with radio-frequency noise from every device in your home and neighborhood. The AudioQuest Niagara 5000 Low-Z Power Noise-Dissipation System attacks that noise with the widest bandwidth-linearized AC filter in the industry: over 30dB of common-mode noise dissipation from 20kHz all the way to 100MHz, linearized to stay effective as line impedance rises with frequency. Its patented AC Ground-Noise Dissipation quiets the most overlooked pollution path of all—the ground line itself.
Power Conditioning That Doesn't Choke Your Amp
Most power conditioners audibly compress dynamics by starving amplifiers of instantaneous current. The Niagara 5000 does the opposite: its unique passive/active Transient Power Correction circuit holds an instantaneous current reservoir of over 90 amps peak—delivered for the 20-30 millisecond bursts today's current-starved power amplifiers demand. Four dedicated high-current outlets feed amplifiers and powered subs with dynamics fully intact; eight ultra-linear filtered outlets pamper your source components.
Protection That Never Sacrifices Itself
Conventional surge strips use sacrificial parts that degrade with every hit—and can fail without warning. The Niagara 5000's non-sacrificial surge protection withstands repeated AC surges and spikes up to 6,000 volts and 3,000 amps without sustaining damage, and it's sonically non-invasive. Rack-friendly at 17.5 inches wide, the Niagara 5000 anchors serious two-channel and theater systems alike.
Features & Specifications
Transient Power Correction — 90+ amp instantaneous current reservoir keeps amplifier dynamics uncompressed.
Ultra-Linear Noise Dissipation — Over 30dB common-mode dissipation, 20kHz-100MHz, linearized across the band.
Patented Ground-Noise Dissipation — Quiets noise riding on the AC ground line itself.
12 Outlets, Purpose-Sorted — 4 high-current outlets for amps; 8 linear-filtered outlets for sources.
Non-Sacrificial Surge Protection — Survives repeated 6,000V/3,000A events with no degradation.

Frequently Asked Questions
Will it limit my amplifier's dynamics?
No—that's the Niagara's defining trick. The Transient Power Correction circuit actually stores current and releases it on demand, so power amps plugged into the four high-current outlets get more instantaneous current than the wall alone provides, not less.
How is this different from a surge strip?
A surge strip uses sacrificial components that wear out with each strike and add noise while they're at it. The Niagara 5000's protection is non-sacrificial—it survives repeated major surges undamaged—and its core mission is noise dissipation across an enormous bandwidth, which cheap strips don't attempt at all.
Which components go in which outlets?
Power amplifiers, powered subwoofers, and receivers go in the four high-current Transient Power Correction outlets. Source components—streamers, DACs, turntables, phono stages, preamps—go in the eight ultra-linear filtered outlets. Call us and we'll map out your exact system.
Do I need a special power cord?
The Niagara 5000 connects to the wall with a detachable high-current AC cord (sold separately). A heavy-gauge, low-impedance cord—such as AudioQuest's NRG Series—lets the Transient Power Correction circuit perform at its full potential. Ask us for a recommendation.
