Placement or proximity to other components is not critical, and, under standard use, the Niagara 3000EU does

not produce any appreciable heat. The Niagara 3000EU may be rack-mounted in a standard 19" rack by attaching

the included Niagara Series 2-RU rack ears. To attach the optional rack ears to the Niagara 3000EU chassis, first

remove the three Torx 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 3000EU'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 3000EU 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 3000EU is placed, a 10-amp-rated (or greater), high-current AC cord must be connected to

the rear-panel AC inlet (IEC-C14) connector. The AC cord must have an IEC-C13 female end connector and a

grounded male Schuko EU1-13P plug for use in the EU, Russia, or any other appropriate country that utilizes this

connector. We highly recommend the use of any AudioQuest NRG-Z, 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 3000EU's Ground-Noise Dissipation

Technology.

When facing the Niagara 3000EU's rear panel, the IEC-C14 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, " page 4).

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.

High-Current | Low-Z Power Outlets

There are two High-Current/Low-Z Power outlets (labeled "1" and "2"). These outlets feature our Transient Power

Correction Technology (55 amps peak - up to 25 mS duration), and are designed to enhance the performance

of power amplifiers via our circuit's low-impedance transient current reservoir. Power amplifiers, monoblock

amplifiers, integrated amplifiers, powered receivers, or powered subwoofers should be connected to these two

outlets. Please set the rear panel switch to "energized" or "1, " as the default position. This affects a portion of the

Transient Power Correction Circuit. (See "Rear-Panel Power Correction Switch. " )

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 amplifier. Quite to the contrary, it will improve the

amplifier's performance by supplying the low-impedance current source that the amplifier's power supply so

desperately needs.

However, the other five AC outlets (Level-X Linear Noise-Dissipation System), are not optimized for most power

amplifiers (*with one exception; see below). They have been optimized for line-level audio preamplifiers, DACs,

universal players, turntables, and video products that utilize constant-current voltage amplifier circuits. These

circuits never suffer 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 3000EU'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.
