Operation and Continuous Use
Power Switch/Circuit Breaker and LED Power Indicator
Once the AC cords are properly connected to the AC source tap, and the components are connected to the
appropriate outlet banks, it is safe to energize the Niagara 3000. On the right-hand side of the Niagara 3000's front
panel, there is a black rocker switch. Firmly press the rocker switch so that its upper portion is flush with the front
panel. Typically, within a couple of seconds, you should hear an audible "clack" sound(s) from one or more relays
within the Niagara 3000. At the same time, the front-panel LED power indictor will glow blue, signifying that the
unit is operational. (If this does not occur, see the "Trouble-Shooting Guide" in this manual.)
Rear-Panel Power Correction Switch/Niagara 3000 Current Draw
The default position for this switch should always be "energized" or "1"—even for applications in which there are
no power amplifiers of any kind powered by the Niagara 3000. Defaulting to "energized"/"1" serves two functions:
It activates the full Transient Power Correction Circuit for power amplifiers that would be energized by outlets 1 or
2, and also provides a portion of the Level-X Linear Noise-Dissipation Circuit for outlets 3 through 7. Although no
damage to the Niagara or the connected components will occur, performance will be somewhat compromised
when this switch is not set to the "energized"/"1" position.
The "0" setting of the rear-panel switch disengages a portion of the transient power correction circuit. The switch
was created for instances in which there is either extraordinary amounts of harmonic distortion present on the
utility AC power line (creating easily audible acoustic buzzing from the listening position—rare), or there is some
concern about smart-meter power consumption. These potential issues can be immediately alleviated by placing
the rear-panel switch in the "0" position. The Transient Power Correction Circuit creates a reactive current draw of
as much as 4 to 5 amps RMS at idle (real-world draw is a small fraction of an amp), and electrical technicians who
connect a current probe to a product such as this are frequently alarmed: They suspect that the product is either
broken or that it is drawing a distressingly high amount of current from the wall outlet (akin to a power amplifier
left in full operational mode).
This is actually far from the truth. If the Niagara 3000 was consuming that much current (or even 30% of that level),
it would need to dissipate the energy loss in heat. It would be quite warm (even hot) to the touch, just like most
power amplifiers while in operation. In fact, the Niagara 3000 runs cool, precisely because this current reading is
false. The circuit utilizes massive capacitive reactance across the AC line, which, akin 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/video 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 3000. This is because
the wiring and the circuit breaker that supply power to Niagara 3000 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
