table, cabinet, shelf, or oor. When rack-mounting is required, these feet may be removed with a standard Phillips
screwdriver. The Niagara 5000’s design obviates the need for compliant or high-Q isolation feet. Although many
audio/video products benet greatly from these devices, the Niagara 5000 does not.
Placement or proximity to other components is not critical, and, under standard use, the Niagara 5000 does not
produce any appreciable heat. The Niagara 5000 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 5000 chassis, rst remove
the three Phillips 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 5000’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 on a shelf or cabinet, the Niagara 5000 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 5000 is placed, an appropriate 20-amp-rated 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 120VAC
Edison/NEMA plug for use in North America or Taiwan. We highly endorse the use of any AudioQuest NRG Series
20-amp-rated AC cord as the Niagara-5000’s Ground-Noise Dissipation technology relies on its use, but the Niagara
5000 will function adequately with any appropriate AC cord that meets the aforementioned requirements.
When facing the Niagara 5000’s rear panel, the IEC-C20 inlet is located on the unit’s lower-left side. The AC input
cord must be connected to an appropriate AC outlet (see “Power Source,” page 6). Though a conventional AC
outlet will function safely and yield high performance, for the very best sonic performance, we highly endorse the
installation of the AudioQuest NRG Edison 20 (or NRG Edison 15, if the electrical panel will only accommodate a
15-amp RMS service).
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 5000’s NRG Edison AC outlets – WARNING!
The AudioQuest NRG Edison AC outlets feature the strongest grip of any commercially available AC outlet in
history. There are many reasons this was done—lower impedance, superior transient current delivery, and vastly
reduced noise, to name a few. However, there is a price to be paid for superior performance: It will take some time
and patience to both insert an AC cord into and remove an AC cord from these receptacles.
We have made every eort to exercise these receptacles during testing and nal inspection, but they will still
require slow and careful “wiggling”: When either inserting a plug into these receptacles or removing an AC cord’s
male plug from the receptacles, gently move the male AC cord’s plug from side to side while providing 7 an even
forward or backwards pressure. If you nd it is simply too dicult to insert an AC cord’s male plug into one of
the outlets, it may be that its male prongs are slightly oversized due to either its design or generous quantities of
plating material.
