Introduction
The science of AC power is not simple; it demands focus, and the devil is in the details. In fact, the mammoth
increase in airborne and AC-line-transmitted radio signals, combined with overtaxed utility lines and the ever-
increasing demands from high-denition audio/video components, has rendered our utilities’ AC power an
antiquated technology.
Where Alternating Current (AC) is concerned, we’re relying on a century-old technology created for incandescent
lights and electric motors—technology that was certainly never meant to power the sophisticated analog and
digital circuits used in premium audio/video systems. To properly accommodate the promise of today’s ever-
increasing bandwidth and dynamic range, we must achieve extraordinarily low noise across a wide range of
frequencies.
Further, today’s power ampliers are being taxed for instantaneous peak-current demand, even when they’re
driven at modest volumes. Although we have seen a substantial increase in both dynamics and bass content from
our audio software, the loudspeakers we employ to reproduce them are no more ecient than they were two
to four decades ago. This places great demands on an amplier’s power supply, as well as the source AC power
supplying it.
Our systems’ sensitive components need better alternating current—a fact that has resulted in a host of AC power
conditioning, isolation transformers, regeneration ampliers, and battery back-up system topologies. Through
dierential sample tests and spectrum analysis, it can be proven that up to a third of a high-resolution (low-level)
audio signal can be lost, masked, or highly distorted by the vast levels of noise riding along the AC power lines
that feed our components. This noise couples into the signal circuitry as current noise and through AC ground,
permanently distorting and/or masking the source signal.
All sincere attempts to solve this problem must be applauded since once the audio/video signal is gone, it’s
gone forever...
For AudioQuest, honoring the source is never a matter of simply using premium “audiophile-grade parts” or
relying on a proprietary technology—common approaches used within the audiophile market. For years, we
have all been witness to the same, seemingly endless audiophile debates: Valves versus transistors. Analog versus
digital. Can cables really make a dierence? The debates go on and on. While we, too, can brag about our many
unique technologies, 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,
they may also impart ringing, current compression, and non-linear distortions that are worse than the disease.

The Niagara 7000EU uses both our patented AC Ground Noise-Dissipation System and the widest bandwidth-
linearized noise-dissipation circuit in the industry. Our unique passive/active Transient Power Correction Circuit
features an instantaneous current reservoir of over 90 amps peak, specically designed for modern current-
starved power ampliers. Most AC power products featuring “high-current outlets” merely minimize current
compression; the Niagara 7000EU corrects it.
Though it’s easy to boast, it’s quite another thing to create a solution that is consistent, holistic, functional, and
that honors veriable science. It’s not enough to reduce AC line noise and its associated distortions at just one
octave, thus leaving vulnerable the adjacent octaves and octave partials to noise, resonant peaking, or insucient
noise reduction. Consistency is key. We should never accept superior resolution in one octave, only to suer from
masking eects a half-octave away and ringing artifacts two octaves from there. This is the principal criterion for
AudioQuest’s Low-Z Power Noise-Dissipation System.
The Niagara 7000EU represents over 20 years of exhaustive research and proven AC power products designed
for audiophiles, broadcast engineers, and professional audio applications. Every conceivable detail has been
addressed: In the Niagara 7000EU, you’ll nd optimized radio-frequency lead directionality; run-in capacitor
forming technologies developed by Jet Propulsion Laboratories and NASA; and AC inlet and outlet contacts with
thick direct silver plating over beryllium copper, assuring superior conductivity and the tightest grip possible.
A great system is built from a solid foundation, and that foundation starts with power. With an AudioQuest
Niagara 7000EU, you’ll experience for the rst time the clarity, dimensionality, frequency extension, dynamic
contrast, and grip your system has always been capable of delivering—if only the power had been right!
We welcome you to experience the Niagara 7000EU and hear rsthand the remarkable results of highly optimized
power management: startlingly deep silences, stunning dynamic freedom, outstanding retrieval of ambience
cues, and gorgeous delineation of instruments and musicians in space. Once you’ve experienced it, it may seem
so elegant, so logical, and so fundamental that you nd yourself wondering why it hadn’t been done before.

Installation
Unpacking
Before unpacking your Niagara 7000EU, 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 7000EU, these packing materials will
ensure the safest transportation.
The double box set should contain the Niagara 7000EU (220-240V Schuko AC Outlets), two foam inserts, owner’s
manual, Quick-Start Guide, front-panel polishing cloth, rack-mount kit, and warranty registration card. Registration
is recommended. In the event that your original ownership documents are lost, your registration can be used to
establish whether the unit is within the warranty period.
Safety Information | Warnings
Before operating the Niagara 7000EU, please read and observe all safety and operating instructions (or, at the
very least, the Quick-Start Guide). Retain these instructions for future reference.
¡Do not disassemble or in any way modify the Niagara 7000EU. There are no user-serviceable
parts inside.
¡Keep away from moisture and avoid excessive humidity.
¡Do not allow liquids or foreign objects to enter the unit.
Servicing | Return to AudioQuest
Servicing of the Niagara 7000EU must be performed by AudioQuest, and is only required when:
¡The Niagara 7000EU has been exposed to rain, ooding, or extreme moisture.
¡The Niagara 7000EU does not appear to operate normally. (See “Trouble-Shooting Guide.”)
¡The Niagara 7000EU has been dropped and sustained considerable physical damage.
If sending the Niagara 7000EU to AudioQuest for servicing (or shipping it for any reason), please use the factory-
approved packaging materials. If you have lost any of these (double carton, two foam inserts, one poly bag),
please contact AudioQuest for replacements. We will provide replacement packaging materials for a nominal
charge; shipping costs will be paid by the individual or company requesting the packaging material. Please do
not rely on other methods of packaging, including those provided or suggested by packaging/mailing stores.
These methods and materials could seriously damage the product, as well as its nish. Even the loss of the thick
polybag is enough to permanently damage the nish during transport. If you have lost the original packaging
material, please request replacement materials from AudioQuest.
Power Source
Ideally, the power source to which the Niagara 7000EU is connected should be adequate for use at 220V to
240V single phase nominal voltage, 16 amps (current capacity RMS or greater). However, the Niagara 7000EU will
operate very well with a 10-amp service outlet. If the maximum current capacity available is 10 amps, and the
system exceeds 10 amps RMS current capacity, it is possible that there may be nuisance tripping at your electrical
service panel. This is not a safety issue; the electrical panel’s circuit breaker will trip if the maximum current
capacity is exceeded.
For proper operation, the Niagara 7000EU requires a safety ground (supplied via the power utility AC wall outlet).

6
Placement
The Niagara 7000EU is manufactured with four rubber textured polymer feet for safe, secure placement on any
table, cabinet, shelf, or oor. When rack-mounting is required, these feet may be removed with a standard Phillips
screwdriver. The Niagara 7000EU’s design obviates the need for compliant or high-Q isolation feet. Although
many audio/video products benet greatly from these devices, the Niagara 7000EU may not.
Placement or proximity to other components is not critical, and, under standard use, the Niagara 7000EU does not
produce any appreciable heat. The Niagara 7000EU may be rack-mounted in a standard 19” rack by attaching the
optional Niagara Series 3-RU rack ears. To attach the optional rack ears to the Niagara 7000EU chassis, rst remove
the three Torx athead screws from the front portion of both the left and right sides of the cover assembly. Next,
mount the rack ears ush against the back of the Niagara 7000EU’s front panel. Finally, secure the rack ears into
place by installing the rack-mount kit’s Phillips pan head SEMS screws.
When tight installations do not provide adequate room in a rack, shelf, or cabinet, the Niagara 7000EU can actually
be placed on its side. Such placement will pose no safety or performance compromises, but we recommend
placing a soft towel or carpet under the unit to prevent the chassis and front panel from being scratched or
marred in any way.
Connection to Audio/Video Components
AC Cable Routing
Once the Niagara 7000EU is placed, an appropriate 16-amp-rated high-current AC cord must be connected to the
rear-panel AC inlet (IEC-C20) connector. The AC cord must have an IEC-C19 female end connector and a grounded
male 220-240VAC Schuko plug. We highly recommend the use of any AudioQuest 16-amp-rated Wind Series
or High-Current Storm Series AC cable. Because these cables feature conductors that have been meticulously
controlled for proper low-noise directionality, they will ensure the best possible results from the Niagara 7000EU’s
Ground-Noise Dissipation Technology.
When facing the Niagara 7000EU’s rear panel, the IEC-C20 inlet is located on the unit’s lower-left side. The AC inlet
cord must be connected to an appropriate AC outlet (see “Power Source”).
Whenever possible, it is best to keep at least three inches (approximately 7cm) between AC cables and any signal
cable. When this is not possible in a practical layout of system cabling, crossing the AC cables to signal cables at
90 degrees is best to minimize induced noise.
Connecting AC cables to the Niagara 7000EU’s NRG Schuko AC outlets – WARNING!
The AudioQuest NRG Schuko AC outlets feature (as do all Schuko female receptacles), reversible polarity
connection. Though both orientations are safe to use, only one is correct for lowest noise and best performance.
All Schuko AC outlets (1 through 12) can be measured with a polarity checking device to determine which
orientation is best for the AC cord that is connected to your walls’ AC service outlet. Make certain you turn the
front-panel power switch/breaker o between measurements and unplugging the cords.
To determine the optimum orientation of the outlet’s AC cords, a polarity-check device or even a digital
multimeter is not always ideal. This is because many component power supplies feature bi-directional supplies,
but one direction typically has less current leakage than the other. To determine which orientation is best, we
recommend listening to each component individually. Once the optimal orientation has been identied, mark
the outlet and the AC cord’s plug accordingly. The simplest way to make this determination is with no signal
present, but with all volume controls set to maximum. The quieter of the two orientations is the correct one. For
line-level components, it may be necessary to place your ear by the loudspeaker’s high-frequency driver in a
quiet environment or use a familiar audio track to determine the most coherent, non-distorted sound.
Marking polarity or orientation on AC outlets or cord plugs should be done discreetly with tape or an ink pen that
can be removed either with isopropyl alcohol or household cleaner on a cotton swab.

7
High-Current | Low-Z Power Outlets
There are four High-Current/Low-Z Power outlets (labeled “1” through “4”). These outlets feature our Transient
Power Correction Technology (90 amps peak - up to 25 mS duration) and are designed to enhance the
performance of power ampliers via our circuit’s low-impedance transient current reservoir. Power ampliers,
monoblock ampliers, integrated ampliers, powered receivers, or powered subwoofers should be connected
to these four outlets. The primary mono, stereo, or multi-channel power amplier(s) should be connected to AC
outlet 1. This enables the standby sense circuit, which requires the current draw of a power amplier connected
to (and only to) outlet 1. In terms of sonic performance, there is no dierence between outlets 1 through 4. If
the standby sense circuit is not utilized, and the sense circuit bypass switch is set to “Enabled,” any of the three
high-current outlets may be utilized.
For systems with only one or two power ampliers, the two uppermost outlets of the four (outlets 1 and 3) will
provide slightly superior performance due to their closer proximity to the AC outlets’ radio-frequency noise-
dissipation circuit. However, the outlets located directly below will certainly aord exemplary performance.
Regardless of class of operation or circuit topology (valve, solid-state, digital, or otherwise), the Transient Power
Correction Circuit will not compress the current of any power amplier. Quite to the contrary, it will improve the
amplier’s performance by supplying the low-impedance current source that the amplier’s power supply so
desperately needs.
However, the other eight AC outlets (Level-X Ultra-Linear Noise-Dissipation System), are not appropriate
for power ampliers. They have been optimized for line-level audio preampliers, DACs, universal players,
turntables, and video products that utilize constant current voltage amplier circuits. These circuits never suer
from current compression, but their lower input level and higher gain require a more robust means of noise
dissipation. This is key to the Niagara 7000EU’s discrete AC power banks, in that not every circuit is treated the
same, but rather isolated bank by bank and optimized for best performance.
Level-X Ultra-Linear Noise-Dissipation System Power Outlets
There are two banks (with eight outlets) that utilize this technology within the Niagara 7000EU. Further, the rst
bank (AC outlets 5 through 8), are 100% isolated from the second bank (AC outlets 9 through 12). All eight of these
outlets are in turn, 100% isolated from the High-Current/Low-Z bank (outlets 1 through 4). This oers a great
advantage in controlling the complex interactions of RF (radio frequency) and other induced noises present in
the AC power supplied from your utility, the noise that will be present on and in every AC cord, and the noise that
is produced within your system’s components and that “backwashes” into the Niagara 7000EU’s output circuits.
Though it would be simple to recommend putting the digital or video components into bank 2, and the line-
level audio components and turntables into bank 3, the quest for optimal performance is more complex. This
scenario will work, and likely work well, but a certain amount of experimentation is best given the fact that no
lter can eliminate 100% of all noise. The size of many of these RF-induced waveforms possess sinewaves as small
as the edge of a piece of paper, and the interactions are complex. So long as the power ampliers are in their
appropriate banks (outlets 1-4), and the other components are in the remaining banks, you should experience
exemplary performance. Still, for the audiophile with patience, the reward will be system performance with the
highest possible resolution and lowest possible noise.
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 nal stage noise-dissipation circuits. (The same holds true for the High-Current banks.)
Again, because bank 2 is 100% isolated from bank 3, placing a DAC and/or universal player in one isolated group,
and a preamplier and turntable in another, would be an excellent way to start. For systems that are much larger
and require more outlets, try starting with the most basic setup, then adding one component at a time. Try
either of the two isolated bank groups to see which works best for you. The bank that sounds best (yielding the
greatest resolution) is the best one for your system!

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 7000EU. On the right-hand side of the Niagara 7000EU’s
front panel, there is a black rocker switch. Firmly press the rocker switch so that its upper portion is ush with the
front panel. Typically, within a couple of seconds, you should hear an audible “clack” sound(s) from one or more
relays within the Niagara 7000EU. At the same time, the front-panel LED power indictor will glow blue, signifying
that the unit is operational. (If this does not occur, see the “Trouble-Shooting Guide” in this manual.)
Rear-Panel Power Correction Switch | Niagara 7000EU Current Draw
The default position for this switch should always be “Engaged” or “1”—even for applications in which there
are no power ampliers of any kind powered by the Niagara 7000EU. Defaulting to “Engaged”/“1” serves two
functions: It activates the Transient Power Correction Circuit for power ampliers that would be energized
by outlets 1-4, and also provides a portion of the Level-X Ultra-Linear Noise-Dissipation Circuit for outlets 5
through 12. Although no damage to the Niagara or the connected components will occur, performance will be
compromised when this switch is not set to the “Engaged”/“1” position.
However, there is one exception to this. Niagara 7000EU has an internal current sense circuit that will automatically
engage the Transient Power Correction Circuit, as well as turn it o when your audio/video system is placed in
Standby mode. To utilize this feature, two things must be present:
1. The primary power amplier(s) or powered receiver must be connected to High-Current/Low-Z
Power Correction Outlet Bank 1 (as it is the only power bank with the current sense monitoring
for this circuit function).
2. The primary power amplier(s) or powered receiver must have a power standby mode, and its
current consumption at 230VAC in standby mode must not exceed 28 watts. (Although 1 watt is
an industry standard for standby power, many great ampliers routinely dismiss it for reasons of
performance over power savings. Therefore, you should consult the specication sheet in your
amplier’s user manual.)
If these two requirements cannot be met, simply place the power correction circuit switch in the “Engaged”
position and leave it there! Rest easy, knowing that you will receive every last bit of performance the circuit can
deliver. However, if your system allows for the scenario listed above and your amplier(s) or powered receiver
meets the criteria listed above, you may wish to take advantage of the standby circuit. (It is likely that many
systems will meet these criteria. However, if the standby function is not important to you, simply leave the switch
in the “Engaged” position).
The standby function was not created to place the connected system into a standby or switched mode, but rather
to place the Transient Power Correction Circuit into standby mode (disengaged), for instances when the system is
powered but not functioning (i.e., when there is no signal present). This was implemented because the Transient
Power Correction Circuit creates a reactive current draw of as much as 9 to 10 amps RMS at idle (real world draw
is a small fraction of an amp), and electrical technicians who connect a current probe to a product such as this
are frequently alarmed: They suspect that the product is either broken or that it is drawing a distressingly high
amount of current from the wall outlet (akin to a power amplier left in full operational mode).
This is actually far from the truth. If the Niagara 7000EU was consuming that much current (or even 20% of that
level), it would need to dissipate the energy loss in heat. It would be quite warm (even hot) to the touch, just like
most power ampliers while in operation. In fact, the Niagara 7000EU runs cool, precisely because this current
reading is false. The circuit utilizes massive capacitive reactance across the AC line, which, akin to a battery, will
both absorb and immediately release the current several times per second. Further, when incorporated with

11
power supplies such as those found in power ampliers, 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/video 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 7000EU.
This is because the wiring and the circuit breaker that supply power to Niagara 7000EU simply look at RMS current
and do not distinguish between reactive loads, resistive loads, or inductive loads, but your utility does.
This circuit and many like it have been utilized for many years, and, when tested into buildings with absolutely
no loads present aside from the transient power correction circuit, there was virtually zero power draw from the
utilities’ power meter. Still, in an age where so-called “smart meters” are omnipresent, and some utilities may or
may not change their standards for “what type of power or current is suitable for billing,” we have gone to great
lengths to oer an alternative to those who may be concerned, but who nevertheless wish to achieve the best
possible audio/video performance.
Again, if you wish to utilize this feature, and your amplier(s) and/or powered receiver meet the criteria, simply
place the Power Correction Switch in the “Standby” position. Otherwise, please leave the switch in the “Engaged”
position.
Ground Fault Circuit Interrupter (GFCI) “Test”Button/Momentary Switch
To oer unparalleled safety and security for both you and your valuable equipment, the Niagara 7000EU
features a ground fault interruption circuit for the Ultra-Linear Noise-Dissipation Dielectric-Biased Symmetrical
Power outlets. This will trip the front-panel power switch (which also acts as an ultra-low resistance 16-amp RMS
magnetic circuit breaker) if there is ever more than 5.5mA of current leakage from Line to Ground or Neutral
to Ground. This is extremely rare, and only exists as these two outlet banks (outlets 5 through 12) utilize two
isolation transformers as part of their circuitry. Since the output is Symmetrical (Balanced), there is voltage
potential on Neutral relative to Ground. In and of itself, this is not at all a problem or danger; in fact, it is precisely
the feature used by the transformer in most components with a linear power supply (in that application, called
“center tapped”).
However, if a connected component’s power supply were to suer a catastrophic failure, there would be a
remote possibility of some AC voltage being present on the component chassis. With the incorporation of the
GFCI, this is not possible, as the current fault would shut o the main power switch within a fraction of a second.
Because we insisted on creating it for optimal performance and safety, this method of redundancy protection is
complex and costly. As a result, the symmetrical outlet banks in the Niagara 7000EU are safer to use than those
found in any home, oce, or hospital.
To ensure the circuit is functioning properly, simply lightly press the button. (It is a momentary switch, so it will
not latch.) This should instantly disengage the front panel’s power switch/circuit breaker, and the blue power
indicator will no longer light. Once this “test” has been performed, you will not need to do so again unless the
unit is moved or has been serviced.
Extreme Voltage Indicator
One portion of the Niagara 7000EU’s non-sacricial surge protection is dedicated to a fast-acting extreme
voltage shutdown circuit. If more than 275VAC is present on the incoming AC line for more than a quarter of
a second, the circuit will instantly open a high-current relay that will disengage the AC power from all of the
Niagara 7000EU’s AC outlets, activating the red front-panel LED “Extreme Voltage” warning indicator. Once the
event has passed, or the building wiring fault has been corrected, the circuit will automatically re-engage.

XFMR-1 and XFMR-2: Front-Panel Circuit Breaker Reset Buttons
If either AC outlet bank 3 (XFMR-1) or bank 2 (XFMR-2) exceed 3 amps RMS capacity, the circuit breaker will trip,
the output to those AC outlet banks will no longer be present, and the breaker will need to be reset. (The tip of a
pencil or pen will work well for resetting the breaker.) If you are uncertain about the current that your connected
products will draw at 220-240VAC input, consult your user manuals. Note: We are referring to 3 amps per isolated
dielectric-biased symmetrical power group; this will have no eect on power ampliers that can draw far in excess
of 3 amps! Most line-level audio products will draw far less than one amp—typically, a fraction of an amp. Most
projectors and at-screen televisions are also well under 3 amps, though there are exceptions. Most plasma
televisions are also under 3 amps, and, contrary to myth, are not current-starved devices; they utilize voltage
ampliers with constant current draw. The Dielectric-Biased Symmetrical Power outlets are the appropriate AC
outlets for these devices. It is quite unlikely that you would ever need to reset these, and far less likely that you
would need to reset both.
Break-in Time | Continuous Use
The Niagara 7000EU is made of a variety of passive and active components. Though every attempt has been
made to reduce the necessity of so-called “break-in,” “burn-in,” or “run-in” time—including high-power run-in
of every critical capacitor in the Level-X Ultra-Linear Noise-Dissipation Circuits—the Niagara 7000EU will benet
from continuous use, just like any other audio/video component. This is not to say that you will be made to
“suer” through weeks or months of intolerable performance until that “magic day” when the parts are fully
formed and ready. On the contrary, the Niagara 7000EU will perform very well from the rst moment you use
it. It will improve gradually, in small increments, over a period of approximately two weeks. While leaving the
Niagara 7000EU turned on during this period will aid the process, it is also perfectly acceptable to turn the unit
o; doing so will simply increase the time it takes to reach nal “break-in.”
The Niagara 7000EU has a 5-year warranty, but it was designed to last for over two decades. Provided that the
Niagara 7000EU is used inside a home, store, studio, or oce with a reasonable climate (7 degrees to 38 degrees
Celsius, with less than 20% humidity), it can be left on continuously; there are no parts that will wear out.

Trouble-Shooting Guide
At AudioQuest, we always appreciate hearing from you. However, if you have questions, problems, or
suspect that your Niagara 7000EU requires service, please start here.
There is no power to any of the AC outlets.
When the Niagara 7000EU’s front-panel LED power indicator glows blue, the unit is operational. If the Power On
indicator is not lit, consider the following:
¡Is the upper portion of the front-panel rocker switch fully ush with the chassis?
¡Is the input AC cord fully inserted into the Niagara 7000EU’s AC inlet?
¡Is the input AC cord properly plugged into the wall AC service outlet?
¡Is the wall’s AC outlet functioning properly?
Plug into the outlet another component, product, or lamp to verify that power is present and that the electrical
panel’s circuit breaker has not tripped. If there are only one or two AC outlets that have no output power, a
component may be malfunctioning. Verify the AC output with a known simple device such as a lamp.
There is no power to any of the AC outlets and the red front-panel
Extreme Voltage indicator is lit.
This indicates that either there is more than 270VAC (+/-3V) present on the wall’s AC service outlet, or the Niagara
7000EU’s protection circuit is mis-calibrated. The latter is quite rare. (This circuit is adjustable, but it’s tested and
retested before it leaves the factory). Use an AC voltage meter to determine if your outlet has too much voltage
to be safe for operation, or if there is a wiring fault that is causing this to occur.
Once the power is brought into a safe range for operation (190VAC to 270 VAC), the Niagara 7000EU’s protection
circuit will automatically switch to operational mode and the blue power indicator will light.
There is no power to any of the Level-X Ultra-Linear Dielectric-Biased
Symmetrical Power outlets.
The front panel has two 3-amp circuit breaker reset buttons that are slightly inset from the edge of the panel. The
button to the left controls AC outlet bank 3, and the button to the right controls AC outlet bank 2. It would be
VERY unlikely that both circuit breakers would trip from too much RMS current draw per outlet group. However,
if one outlet group (banks 2) or the other group (banks 3) has no output, check to see if the breaker for that AC
outlet group has tripped. To reset the breaker: Using the back of a pencil or pen, press the appropriate circuit
breaker reset button into the chassis until it reaches its normal state—slightly loose, with little spring tension.
When resetting or testing the reset of one or both of the front-panel 3-amp XFMR-1 and XFMR-2 circuit breakers,
it is important that the AC outlet group is not connected to a component or product that is defective and has
shorted. To verify that the circuits are working, we recommend disconnecting all but one known properly
functioning product from the AC outlet group.
If after verifying that the circuits are operating (or, if after resetting the circuit breaker for one of the power
groups), you discover that one or multiple products activate the circuit breaker, check the current consumption
rating of that/those products. (Typically, this information can be found on the last page of the component’s
owner’s manual; it should be listed as the power consumption at 230VAC.)
The current specication will typically be in watts. Know that 3 amps at 230VAC equal 690 watts. (You will want to
be at least slightly under that number.) You may simply add wattage ratings to calculate your total consumption:
If you have four components into group one (bank 3 - outlets 9/10/11/12), the maximum capacity of all four
outlets combined is just under 690 watts or 3 amps. The same is true for group two (banks 2 - outlets 5/6/7/8).

15
The main power rocker switch/circuit breaker tripped to the lower (o) position
while the system was playing.
You may have exceeded the maximum current capacity of the Niagara 7000EU. This should be rare, but it may
be possible. Typical power ampliers draw about one-third of their maximum current consumption at 230VAC,
as listed in the product’s specications (typically found in their owner’s manual). This is further complicated
by the fact that the power consumption to the AC outlet banks 3 and 2 is an additional draw on the maximum
current capacity of 16 amps that will trip this switch/magnetic circuit breaker.
The Transient Power Correction Circuit may also contribute to the overall draw seen by the circuit breaker. Still,
it should be rare that the total capacity is exceeded, but, given that some televisions, projectors, and power
ampliers can draw substantial current, it is certainly not impossible. If this is the case, an additional Niagara
7000EU or Niagara 5000EU, and a discrete 16 amp AC service on the same phase of the electrical panel (for
buildings with a 3 phase service), will be required for some or all of the power ampliers.
When a component was plugged into one of the Ultra-Linear Dielectric-Biased
Symmetrical Power outlets and switched on, the main power rocker switch/circuit
breaker tripped to the lower (o) position.
You have likely tripped the GFCI circuit (ground fault protection). This circuit ensures that even in the event of a
catastrophic failure to the connected components’ power supply and/or circuits (demonstrated by full shorting
and possible smoke) there will be no AC voltage on the components’ chassis that could possibly shock a person.
This circuit instantly recognizes if there is more than 5.5mA of current leakage from Line to AC Ground, or
Neutral to AC Ground. This is the maximum current allowed for ALL 8 of the Symmetrical AC outlets. If this
current leakage is detected, the main power switch/magnetic circuit breaker will immediately switch o, thus
protecting the system operator and all others that might come in contact with the system.
It is very rare for this circuit to trip. If it does, the connected component that causes this is either defective (most
likely), or it (and possibly another component on the same Symmetrical Power bank) may have a combined
current leakage to ground that exceeds 5.5mA. Technically, this is not allowed in modern electronic circuit
design, but that does not necessarily mean an otherwise well-performing product with an “unconventional”
power supply is unsafe to use. Such a component may need to be used with either the Niagara 7000EU’s high-
current AC outlets, which do not utilize the GFCI protection circuit, or they may be powered by another discrete
AudioQuest Niagara Series power product, thus preventing the GFCI nuisance tripping.
As a nal check, inspect the GFCI test button on the left side of the Niagara 7000EU’s front panel. It is a momentary
switch and it will not latch; by pressing it lightly into the chassis, it will activate the GFCI protection circuit and
trip the main power switch/magnetic circuit breaker. Though extremely rare, it is possible that the switch could
be stuck in an “on” position from taking a blow during shipping. (The rest of the unit may be perfectly ne, but
the tolerance of this test button switch to the chassis and front panel is tight.) When pressed, the switch should
exhibit some “travel” or “give” and should not feel binding in any way. If the switch feels tight or stuck, there may
be a problem. (This will require servicing, so please be certain.)
My power ampliers sound muddy, compressed, or weak.
The Transient Power Correction Circuit may not be operating. Be sure that all power ampliers, powered receivers,
powered loudspeakers, and or powered subwoofers are plugged into the High Current/Power Correction
AC outlets. If any of these are plugged into the Ultra-Linear Dielectric-Biased Symmetrical Power outlets, the
connected power amplier(s) will be current compressed, as the impedance is too high for any power amplier.
If the power amplier(s) are plugged into the High Current/Power Correction AC outlets, make certain that the
rear-panel Power Correction switch is in the “Engaged” position. Although it is possible for the Power Correction
Circuit to work properly while the switch is in the “Bypass” position (see “Power Correction Switch,” page 6), you

16
might nd that the unit sounds substantially better in the “Engaged” position. If this is the case, it is possible
that the main or primary power amplier is not plugged into High-Current AC bank 1, the power amplier has
insucient 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. Yet,
even with the current sense circuit functioning properly, audiophiles may prefer the “Engaged” position, as it will
slightly decrease the impedance of the Transient Power Correction Circuit.
My Niagara 7000EU has no power ampliers connected to it, but it sounds odd or
not quite as good as it once did.
The Transient Power Correction Circuit also aids the Ultra-Linear Noise-Dissipation Circuits. Make certain that
the rear-panel Power Correction switch is in the “Engaged” position.
A technician or electrician found that my Niagara 7000EU consumes over 8 amps
of current. Is it broken?
No, it’s not broken, and it’s not drawing 8+ amps in any conventional sense. The Niagara 7000EU’s Transient
Power Correction Circuit creates a reactive current draw of as much as 9 to 10 amps RMS at idle, and, when
incorporated with power supplies such as those found in power ampliers, the current readings decrease. This
is a vector load, which will vary with the connected equipment. When plugged into an AC service that has no
other electrical draw, it is typical to see a real-world RMS power draw well below 15 watts at idle. (For an in-
depth explanation of the circuit, see “Power Correction Switch.”)
I did not notice hum with any prior power device, but there is a hum in my system
with the Niagara 7000EU.
Typically, this will not occur. In fact, the Niagara 7000EU’s two Ultra-Linear Dielectric-Biased Symmetrical Power
outlet groups are 100% isolated from one another, 100% isolated from the High Current/Power Correction outlet
group, and oating. This allows opportunities to break up ground loops in an audio system. However, the hum
created by ground loops (typically, a voltage dierential from Neutral to Ground among two or more signal-
connected devices in an audio/video system) can at times be quite complex and dicult to easily diagnose.
To diagnose the hum/ground loop: With everything else unplugged, start with the simplest system that can still
play music through your loudspeakers. Use a source such as a universal player, computer, or a turntable so there
is no external cable or satellite cable connected to ANY of the associated components. Is there any hum? If yes,
and there is more than one line-level (non-power amplier) component connected in this “minimalist” test, try
placing one in Symmetrical Power group one and the other in group two.
If the hum no longer persists under these conditions (which is likely), try reconnecting each additional component
into the Niagara 7000EU one at a time. Once you nd the component that creates the hum, you can possibly
achieve increased isolation by connecting it to a dierent Ultra-Linear/Symmetrical Power outlet group. This
can typically help, as well as increase overall system performance by decreasing system noise. If adding a cable
or satellite signal to the system reintroduces the ground-loop hum, that incoming signal line may require an
isolation transformer or humbucker.
If it seems that hum didn’t occur before, but does now, it’s most likely that the hum was in fact always there. The
dierence is simply a matter of degree. Sometimes the ground loop dierence is right on the edge of breaking
into an area where it’s audible, instead of only measureable with electronic measurement instruments. The
very act of creating better connections, thus minimizing the impedance to the power ampliers, can tip the
scales. If the hum/ground-loop exists on the incoming satellite or cable line, then it will be necessary to x the
real problem. This is common with large custom install systems. As these signal lines are always grounded in a
dierent place and at a dierent potential than the rest of the system’s ground return, the system will benet
greatly by utilizing isolation under these conditions.

17
In rare circumstances, there are some computer peripherals or DACs that feature grounded AC cords and whose
circuits rely on a hard AC ground (i.e., they cannot be oated). 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, 1000, or 700 Low-Z Power Noise-Dissipation System.
My home or grounds were hit by lightning. The Niagara 7000EU seems to be
functioning properly. Should it be sent in for inspection or service?
If you see or smell smoke coming from the unit, it needs service. Otherwise, if it functions after such an event
(which is very likely), there is nothing that would be compromised or damaged. If it fails after such an event, it
will fail totally. However, it’s unlikely that this would occur. The circuit is designed to easily handle any voltage
or current surge that could possibly make it past an electrical panel. The force required to damage the Niagara
7000EU via a power surge would melt the panel and burn the building (in which case, the Niagara 7000EU is the
least of your worries).
How do I clean the chassis and/or the electrical contacts?
The Niagara 7000EU’s black-painted chassis and dark chrome front panel can be cleaned with AudioQuest
CleanScreen or a modest misting of household window cleaners. Please use soft cotton or wool toweling to
remove the liquid from the metal and painted surface. Whenever possible, use the supplied polishing rag for the
front panel, only using liquid cleaner when oil or grime is beyond the polishing cloth’s capacity to thoroughly
clean. Never use alcohol or solvent-based cleaners. They can damage the surfaces, paint, and silk-screening
material.
The AC inlet, outlet posts, and grips are all generously plated with silver. There is no need to clean these if they
are not exposed to foreign substances such as grease and dirt. Silver oxide is a superior conductor to silver itself.
If cleaning is required, Isopropyl alcohol (preferably 99% purity) on a cotton swab is best for the inlet tabs. Some
manufacturers provide specialized cleaners for the AC output surfaces. Again, however, cleaning these surfaces
will most likely be unnecessary.
Note: A pipe cleaner or cleaning swab with a wood stick and compact wool tip (available from an electronics
supply house) will be superior to household swabs. When working in a small area such as an AC outlet, this is
critical. Loose strands of cotton may damage the AC outlet. Damage to an AC inlet or outlet due to cleaning is
not covered under your warranty. If you damage an inlet or outlet in an attempt to clean it, you will be charged
for the repair and you will be responsible for all shipping costs (this is overseas - please use caution).
I hear a slight buzzing sound coming from the Niagara 7000. Is it damaged?
No, it’s not damaged (or, at least, damage is very unlikely). If you’re in an extraordinarily quiet room and you hear
this buzzing sound only when in relatively close proximity to the Niagara 7000EU, or only when you place your
ear next to the unit, the buzzing is normal and, unfortunately, cannot be eliminated.
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 oset voltage that should not be
present, even the nest power transformers in the world will react to this problem. In order to reduce or eliminate
this distortion, the power transformers try to turn it into heat, causing the transformers’ steel alloy core to hum
at 50 cycles per second and all harmonics above that. This has no eect on the performance of the Niagara
7000EU or its connected components.

18
Ninety-eight percent of installations never exhibit this problem, but that’s no help to the 2% that do. The Niagara
7000EU features a very robust DC-blocking circuit that feeds the input or primary to each of the AC isolation
transformers, but there are times when otherwise fabulous audio/video component or computer products can
nevertheless backwash DC (or a severely asymmetrical chopped waveform) into the output secondary of the
transformers. When this occurs, it is necessary to perform some experimentation: Remove each component and
its AC cord, one at a time, from the Ultra-Linear Dielectric-Biased Symmetrical Power outlets - groups two and
three. (The High Current/Power Correction Outlets are in no way connected to these transformers, so these may
stay as they are.)
Once magnetostriction is present on a transformer core, the audible noise (saturation) becomes greater as the
transformer is asked to pass more current. Moving some products, or a moderately high-current product, to
the opposite transformer group may alleviate the problem. Additionally, many computer drives come with
external (wall-wart type), switching power supplies that feature chopped AC waveforms. If mechanical noise is
present, such power supplies may be better served by the Niagara 7000EU’s High Current outlets or by using an
additional, smaller Niagara Series product, such as the Niagara 5000EU or Niagara 3000EU, which do not employ
transformers.
If you notice that the slight buzzing sound has increased over time (i.e., was once negligible, but is now quite
noticeable), please understand that the Niagara 7000EU’s AC isolation transformers are like the proverbial
“canary in a coal mine.” In all likelihood, the Niagara 7000EU has not developed a problem. (If you remove all of
the AC output cords and listen for the slight buzzing sounds, you will likely nd that they are gone.) However, it
is possible that otherwise state-of-the-art components are causing the problem.
Investigate valve or vacuum tube power supplies. If the tube(s) are wearing, some circuits will oset some DC
onto the AC line and back to the Niagara 7000EU, or aect the AC waveform that the Niagara 7000EU feeds. If
the components were going into a power lter or conditioner without transformers, you would never be aware
of the problem, but transformers never lie: It’s time to replace one (or more) of the power supply tubes!
