AudioQuest Niagara 3000 Power Conditioner & Surge Protection

7 outlets | 55+ amp transient current reservoir | Level-X noise dissipation | Non-sacrificial surge protection

The AudioQuest Niagara 3000 is a high-performance power conditioner and Low-Z Power Noise-Dissipation System designed for serious two-channel audio, home theater, and custom-installed systems. It brings much of the technology found in AudioQuest’s larger Niagara 5000 and 7000 into a more compact, rack-friendly chassis.

Rather than simply filtering AC power, the Niagara 3000 combines AudioQuest’s patented Ground-Noise Dissipation, Level-X linear noise filtering, Transient Power Correction, and comprehensive equipment protection. Two dedicated high-current outlets are designed for amplifiers, powered speakers, and subwoofers, while five filtered source outlets accommodate sensitive source components.

Key Features

• 7 AC outlets: 2 high-current outlets plus 5 Level-X linear-filtered source outlets.
• Transient Power Correction: Provides a reservoir of over 55 amps peak for up to 25 milliseconds to support high-current demands from power amplifiers.
• 15-amp maximum current capacity: Designed to deliver power without restricting amplifier dynamics.
• Patented Ground-Noise Dissipation: Reduces ground-borne noise without compromising safety or creating low-level ground loops.
• Level-X Linear Noise-Dissipation: Wide-bandwidth filtering designed to reduce AC line and radio-frequency noise consistently.
• Non-Sacrificial Surge Protection: Withstands repeated AC surges and spikes up to 6000V/3000A without requiring sacrificial protection components to be replaced.
• Extreme Voltage Shutdown: Disconnects connected equipment when incoming AC voltage rises approximately 17% above optimal levels and automatically restores operation when voltage returns to a safe range.
• Rack-ready: Compact 2RU-compatible design with rack ears included.
• Power cable sold separately: Allows the Niagara 3000 to be paired with an appropriate AudioQuest AC power cable.

2 High-Current + 5 Source Outlets

The Niagara 3000 separates power-hungry components from more sensitive source electronics.

The two high-current outlets are intended for components such as power amplifiers, integrated amplifiers, powered loudspeakers, and powered subwoofers. AudioQuest's Transient Power Correction provides these components with access to a reservoir of more than 55 amps peak during short-duration AC current transients.

The five source outlets use Level-X linear filtering to reduce noise for components such as DACs, streamers, preamplifiers, disc players, and other source electronics.

Protection That Doesn't Sacrifice Itself

Unlike conventional surge suppressors that can degrade or require replacement after absorbing significant surges, AudioQuest's Non-Sacrificial Surge Protection is designed to withstand repeated 6000V/3000A input surges without sustaining damage.

Extreme Voltage Shutdown adds another layer of protection by disconnecting the system when incoming voltage reaches an unsafe level and restoring operation once normal voltage returns.

Technical Specifications

Where the Niagara 3000 Fits in the Series

The biggest reason to step up through the range is not simply additional outlets. The 5000 provides greater capacity for larger systems, while the flagship 7000 adds AudioQuest's dielectric-biased symmetrical AC isolation transformers and its most advanced Niagara implementation.

Built for High-End Audio & Home Theater

The Niagara 3000 makes particular sense when a system needs both high-current delivery and serious power protection without moving to the considerably larger and more expensive Niagara 5000 or 7000.

Its combination of five source outlets and two high-current outlets makes it well suited to systems built around an integrated amplifier or stereo power amplifier, along with a streamer, DAC, preamplifier, turntable power supply, or other front-end components.
