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 3000'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.
*Compared to its larger Niagara siblings, the Niagara 3000 is unique. Even its Source power banks are capable of
passing extraordinarily high transient current before soft-clipping (in excess of 50 amps peak). So, if you have one
or two main power amplifiers and an additional one to two subwoofers, use the High-Current AC outlets for the
power amps. The subwoofers will still yield superb results when connected to any of the five AC source outlets.
Level-X Linear Noise-Dissipation System Power Outlets
There are five outlets that utilize this technology within the Niagara 3000. All five of these are in turn isolated from the
High-Current/Low-Z outlets 1 and 2. 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 3000's output circuits.
Though it would be simple to recommend putting the digital or video components into outlets 3 and 4, and the line-
level audio components and turntables into outlets 6 and 7, 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 possess sinewaves as small as the edge
of a piece of paper, and the interactions are complex. So long as the power amplifiers are in their appropriate outlets (1
and 2), and the other components are in outlets 3 through 7, 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.
To achieve that optimal performance, we recommend the following guidelines. For systems that utilize very few
components, placing a DAC and/or streamer into one isolated group (3 through 5), and a preamplifier and turntable
in another (6 and 7), would be an excellent way to start. For systems that are much larger and require more outlets, try
starting with the most basic setup, then adding one component at a time. The combination that sounds best (yielding
the greatest resolution) is the best one for system!
