Marking polarity or orientation on AC outlets or cord plugs should be done discreetly with a tape or ink pen that

can be removed with either isopropyl alcohol or household cleaner on a cotton swab.

High Current/Low-Z Power Banks

There is one High Current/Low-Z Power banks (labeled AC outlets "1" through "4"). The outlets feature our Transient

Power Correction Technology, and are designed to enhance the performance of power amplifiers via our circuit's

low-impedance transient current reservoir. Power amplifiers, mono-block amplifiers, integrated amplifiers,

powered receivers, or powered subwoofers should be connected to these four outlets. The primary mono, stereo,

or multi-channel power amplifier(s) should be connected to AC outlet number 1. This enables the standby sense

circuit, which requires the current draw of a power amplifier connected to (and only to) outlet number 1. In terms

of sonic performance, there is no difference 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 four high current outlets may be utilized.

For systems with only one or two power amplifiers, the two uppermost outlets of the high current banks 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 afford 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 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 eight AC outlets (Ultra-Linear Noise-Dissipation System) are not appropriate for power

amplifiers. 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 5000EU'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.

Ultra-Linear Noise-Dissipation System Power Banks

There are two banks that utilize this technology within the Niagara 5000EU. Both of these are in turn isolated from the

High-Current/Low-Z bank (outlets 1 through 4). This offers 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 5000EU'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 banks 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 filter can eliminate 100% of

all noise, the size of many of these RF-induced waveforms is as small as the edge of this paper you're reading, and the

interactions are complex. So long as the power amplifiers are in their appropriate bank (outlets 1 through 4), and the

other components are in bank 2 (outlet 5 through 8) or bank 3 (outlets 9 through 12), 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.
