table, cabinet, shelf, or floor. When rack-mounting is required, these feet may be removed with a standard Phillips

screwdriver. The Niagara 5000EU's design obviates the need for compliant or high-Q isolation feet. Although many

audio/video products benefit greatly from these devices, the Niagara 5000EU may not.

Placement or proximity to other components is not critical, and, under standard use, the Niagara 5000EU does not

produce any appreciable heat. The Niagara 5000EU 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 5000EU chassis, first remove

the three Phillips flathead screws from the front portion of both the left and right sides of the cover assembly.

Next, mount the rack ears flush against the back of the Niagara 5000EU'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 5000EU 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 5000EU is placed, an appropriate 16-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

220-240VAC Schuko plug. We highly endorse the use of any AudioQuest NRG Series 16-amp-rated AC cord as the

Niagara-5000EU's Ground-Noise Dissipation technology relies on its use, but the Niagara 5000EU will function

adequately with any appropriate AC cord that meets the aforementioned requirements.

When facing the Niagara 5000EU'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).

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 5000EU'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 thus, 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 off 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 multi-

meter 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. It is best to listen to each component one at a

time and determine which orientation is best, then mark the outlet and the AC cords plug. The simplest means of

determining this is with no signal, 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 high

frequency driver in a quiet environment, or; use audio to determine the most coherent non-distorted sound.
