to a battery, will both absorb and immediately release the current several times per second. Further, when

incorporated with power supplies such as those found in power amplifiers, 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 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 5000EU. This is because the wiring and the circuit breaker that supply power

to Niagara 5000EU 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 offer an alternative to those who may be concerned, but who nevertheless wish to

achieve the best possible audio or video performance.

Again, if you wish to utilize this feature, and your amplifier(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.

Extreme Voltage Indicator

One portion of the Niagara 5000EU's non-sacrificial surge protection is dedicated to a fast-acting extreme voltage

shutdown circuit. If more than 270VAC 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 5000EU'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.

Break-in Time/Continuous Use

The Niagara 5000EU 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 Ultra-Linear Noise-Dissipation Circuits—the Niagara 5000EU will benefit from continuous

use, just like any other audio/video component. This is not to say that you will be made to suffer through weeks

or months of intolerable performance until that magic day when the parts are fully formed and ready. On the

contrary, the Niagara 5000EU will perform very well from the first moment you use it. It will improve gradually, in

small increments, over a period of approximately two weeks. While leaving the Niagara 5000EU turned on during

this period will aid the process, it is also perfectly acceptable to turn the unit off; doing so will simply increase the

time it takes to reach final "break-in. "

The Niagara 5000EU has a five-year warranty, but it was designed to last for over two decades. Provided that the

Niagara 5000EU is used inside a home, store, studio, or office with a reasonable climate (7 degrees to 38 degrees

Celcius, with less than 20% humidity), it can be left on continuously; there are no parts that will wear out.
