Niagara 7000 Features ¡¡ Dielectric-Biased AC Isolation Transformers: AQ’s patented technology greatly reduces nonlinear distortions that have previously plagued even the finest magnetic-based systems, all the while increasing the bandwidth and efficiency of the transformers’ noise dissipation. ¡¡ Transient Power Correction: Provides over 90 amps peak instantaneous current reservoir with reduced line impedance for current-starved power amplifiers, whether they incorporate linear or switching power supplies.
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, these approaches may also impart ringing, current compression, and non-linear distortions that can render the cure worse than the disease.
Installation Unpacking Before unpacking your Niagara 7000, inspect the carton for any obvious damage to the boxes and internal protective materials. If internal damage is likely, contact the carrier who delivered the unit. If shipping damage is evident on the product, then please contact your shipping carrier. Please save all shipping and packing materials. Should you move or otherwise need to transport your Niagara 7000, these packing materials will ensure the safest transportation.
Placement The Niagara 7000 is manufactured with four rubber textured polymer feet for safe, secure placement on any table, cabinet, shelf, or floor. When rack-mounting is required, these feet may be removed with a standard Phillips screwdriver. The Niagara 7000’s design obviates the need for compliant or high-Q isolation feet. Although many audio/video products benefit greatly from these devices, the Niagara 7000 does not.
This is not a reason to return the Niagara 7000 or abandon the use of such an AC plug! Typically, the outlet in question can be slightly opened up by gradually exercising it with an AC plug. For this, we actually do not recommend an AudioQuest or any other premium brand of AC cord or male plug. For exercising the outlet, obtain from an electrical supply house or hardware store a generic three-prong 15-amp-rated AC cord or plug that affords a generous and secure area to handle.
To achieve that optimal performance, we recommend the following guidelines. For systems that utilize very few components, bear in mind that it is advantageous to use the uppermost outlets in each bank as they have a closer proximity to the final stage noise-dissipation circuits. (The same holds true for the High-Current banks.
Suggested AC Connections 1 Powered LoudSpeaker “Engaged” position must be default setting. See page 10 for use of “Standby” mode.
2 Line-Level Pre Amp Mono Block “Engaged” position must be default setting. See page 10 for use of “Standby” mode.
Operation and Continuous Use Power Switch/Circuit Breaker and LED Power Indicator Once the AC cords are properly connected to the AC source tap, and the components are connected to the appropriate outlet banks, it is safe to energize the Niagara 7000. On the right-hand side of the Niagara 7000’s front panel, there is a black rocker switch. Firmly press the rocker switch so that its upper portion is flush with the front panel.
and immediately release the current several times per second. Further, when incorporated with power supplies such as those found in power amplifiers, the current readings actually come down! This is due to what’s known as a vector load, and it’s quite dynamic in an audio system. In this scenario, there is one thing that can run somewhat warmer than it might otherwise: the AC cord that supplies power to the Niagara 7000.
amps per isolated dielectric-biased symmetrical power group; this will have no effect on power amplifiers that can draw far in excess of 5 amps! Most line-level audio products will draw far less than one amp—typically, a fraction of an amp. Most projectors and flat-screen televisions are also well under 5 amps, though there are exceptions. Most plasma televisions are also under 5 amps, and, contrary to myth, are not current-starved devices; they utilize voltage amplifiers with constant current draw.
Specifications Surge Suppression: Non-sacrificial (nothing to damage with repeated 6000V/3000A input surge tests, which is the maximum that can survive through a building’s AC electrical panel). Extreme Voltage Shutdown Voltage: 140VAC (will activate the main high-current relay to open within less than 0.25 second; automatically resets once the incoming power is within a safe range).
Trouble-Shooting Guide At AudioQuest, we always appreciate hearing from you. However, if you have questions, problems, or suspect that your Niagara 7000 requires service, please start here. There is no power to any of the AC outlets. When the Niagara 7000’s front-panel LED power indicator glows blue, the unit is operational.
The main power rocker switch/circuit breaker tripped to the lower (off) position while the system was playing. You may have exceeded the maximum current capacity of the Niagara 7000. This should be rare, but it may be possible. Typical power amplifiers draw about one-third of their maximum current consumption at 120VAC, as listed in the product’s specifications (typically found in their owner’s manual).
Trouble-Shooting Guide, continued the main or primary power amplifier(s) are not plugged into High-Current AC bank 1, the power amplifier has insufficient current draw to activate the circuit, or the circuit is miscalibrated. When the Power Correction switch is set to the “Engaged” position, the current sense circuit will be defeated.
In rare circumstances, there are some computer peripherals or DACs that feature three-prong grounded AC cords and whose circuits rely on a hard AC ground (i.e., they cannot be floated). Under these rare circumstances, you may obtain better results with that one component plugged into one of the High Current/Power Correction outlets or into an accompanying Niagara 5000, 500, 200, or 100 Low-Z Power Noise-Dissipation System. My home or grounds were hit by lightning.
Trouble-Shooting Guide, continued What you are experiencing is called magnetostriction. When an extraordinarily high quantity of harmonic distortion is present on an AC line, or when the AC line contains some DC offset voltage that should not be present, even the finest power transformers in the world will react to this problem.
