AudioQuest Niagara 5000 Power Conditioner - Black

Not a Power Strip: A Noise-Dissipation System

The AudioQuest Niagara 5000 treats wall power as the first component in your system. That power carries radio-frequency noise from every device in your home and neighborhood. The 5000 is built to dissipate that noise, and to supply current to amplifiers that need it.

It has twelve outlets sorted by job. Four high-current outlets with Transient Power Correction feed power amplifiers and powered subwoofers. Eight ultra-linear filtered outlets serve source components. It is rated for a maximum input of 20 amps RMS.

Non-sacrificial surge protection withstands repeated AC surges and spikes up to 6,000 volts and 3,000 amps without damage. Conventional surge strips use parts that degrade with every hit. This design keeps protecting after the storm.

A Reservoir for Amplifiers, a Wide Filter for Sources

AudioQuest's passive/active Transient Power Correction circuit holds an instantaneous current reservoir of over 90 amps peak for up to 25 milliseconds, the kind of burst that current-hungry amplifiers demand. AudioQuest designed it to supply current rather than limit it.

The filter is rated in excess of 30dB of common-mode noise dissipation from 20kHz to 100MHz. It is linearized to stay effective as line impedance rises with frequency. That means noise is reduced evenly across the band instead of at one narrow spot.

The patented AC Ground-Noise Dissipation system works on the ground line itself, which AudioQuest calls the most overlooked path for noise. The chassis is 17.5 inches wide, 5.875 inches tall with feet (5.24 without) and 17.2 inches deep, and weighs 44 pounds. Rack ears are not included, though an optional 3-RU rack kit is available.

Who Is This Power Conditioner Best For?

• You run power amplifiers or monoblocks. Four high-current outlets back them with over 90 amps peak, so the wall is not the limit
• You have a long chain of source components. Eight ultra-linear filtered outlets give each a filtered feed
• One circuit feeds a lot of gear. A 20-amp maximum input gives a big system more headroom
• You have lost equipment to a surge. Protection that survives repeated hits keeps working, so no spent strip needs replacing
• You expect a power cord in the box — the 5000 ships without one. It needs a heavy-gauge, low-impedance cord, and our power cables cover that run

How Does It Connect to Your System?

The Niagara 5000 connects to the wall with a detachable high-current AC cord. A heavy-gauge, low-impedance cord, such as AudioQuest's NRG Series, lets the Transient Power Correction circuit do its work.

Plug power amplifiers, powered subwoofers and receivers into the four high-current outlets. Put streamers, DACs, turntables, phono stages and preamps into the eight filtered outlets. Call us and we will map out your exact system.

Amps get the reservoir. Sources get the filter.

Pairs Well With

Building your system? Here are some great companions for the AudioQuest Niagara 5000:

• Power cables for the detachable cord the 5000 needs
• Monoblock amplifiers for the high-current outlets
• Preamplifiers for the filtered source outlets
• Audio racks built for a full-width chassis

Frequently Asked Questions

Will it limit my amplifier's dynamics?

Transient Power Correction does the opposite of limiting. It stores current and releases it on demand. Amplifiers in the four high-current outlets get more instantaneous current than the wall alone provides.

How is this different from a surge strip?

A surge strip uses sacrificial parts that wear out with each strike. The Niagara 5000's protection is non-sacrificial and survives repeated large surges. Its main job is noise dissipation across a very wide band.

Which components go in which outlets?

Power amplifiers, powered subwoofers and receivers go in the four high-current outlets. Source components go in the eight filtered outlets, including streamers, DACs, turntables, phono stages and preamps.

How much current can it handle?

It is rated for a maximum input of 20 amps RMS. Standby draw is typically under 0.25 amps at 120VAC. That headroom suits a large system with several amplifiers. Check your outlet and circuit before you plan the run.

Which power cord should I use?

Any detachable high-current AC cord will connect. AudioQuest's NRG Series is a good match for this conditioner. Ask us and we will recommend one for your system.

What's the warranty?

AudioQuest lists a five-year warranty for the Niagara 5000, for the original purchaser. Registration is encouraged but is not a condition of the warranty.
