By generating new AC, the Premier produces up to 1500 watts of regulated AC power at an efficiency of 85% with little to distortion or noise. The Premier has ten outlets, five IsoZones™, a built in power sequencer, THD analyzer, voltage meter, MultiWave, CleanWave and a remote control to access all the features.
The Premier is our finest power product ever made and replaces the P300, P500, P600, P1000 and P1200 Power Plants.
The Premier is housed in a scrumptious new chassis whose industrial design is based on the BMW automobile and is the brain child of one of our country’s brightest new ID talents, Chris Malato.
Not just another “box” the Premier marries solid aluminum castings, extrusions, milled blocks and hand crafted parts to form one of the most stunning pieces of industrial art anyone’s laid eyes on. You’d be quite proud to display this beauty in your system.
To understand how the Premier works and why it is efficient, it’s necessary to first understand how the older Power Plants work and why they are not efficient.
The original Power Plant technology was relatively simple: a stereo power amplifier fed 60 Hz from a sine wave generator. The output of the stereo amplifier was connected to the AC input of the connected equipment. Each channel of the stereo amplifier produced ½ the necessary 60Hz sine wave voltage and when you combined the two channels across a load, you got 120 volts (in the US) at 60Hz.
The Power Plants used conventional class AB power amplifiers to drive the power and
these types of amplifiers are about 50% efficient, hence the low efficiency of the Power Plant. The reason these amplifiers are inefficient stems from the fact that they require a large power supply voltage, generating heat as the signal travels between the supply voltages extremes.
There are other amplifier topologies that are more efficient, like the Class D amplifiers we use in the G Series, but these produce too much noise to be used as a Power Plant.
In the G Series, this noise doesn’t matter because it feeds a loudspeaker which cannot reproduce the 500 kHz noise and is unaffected. But a Power Plant has to be clean; very clean.
Bob’s discovery was a way to lower the large power supply voltages so the amp was efficient. To do this, Bob figured out a way to move the entire power supply up and down in lock step with the sine wave generator, so the voltage across the amp is only what is needed, thus increasing the efficiency. In most other respects, the old and the new Power Plants are the same.
Let’s take a tour
Now that we know how it works, let’s see what a Premier has to offer.
Perhaps the biggest benefit is unlimited power. At 1500 watts there’s enough power for eve
n the most demanding systems. Whether it’s an audio based two channel system or a video based multi-channel home theater, 1500 watts will power pretty much anything you have.
The Premier takes what the wall AC has to offer and converts it into perfect AC. Rebuilding the sine wave into this low distortion waveform is a huge benefit to owner’s of the Premier. Most AC power is deformed and flawed out of the wall, with the top of the sine wave missing. The Premier fixes this problem as well as provides instantaneous voltage regulation to connected equipment, regardless of the power demands.
Surge and spike protection are unparalleled in the Premier. Not only does your equipment benefit from the over under voltage control of the Premier, instantaneous non-volatile spike protection, but the voltage regulating capabilities of the Premier keep everything connected to it at a perfect steady voltage regardless of input conditions.
Inside is an amazing piece of construction. From the custom built Power Port AC receptacles, to the 1/4
inch thick copper bars that carry the power from the Power Cartridge to each of the receptacles with zero loss, hundreds of hours of design time have gone into the building of this amazing power delivery system.
Isolation from connected equipment. The 5 IsoZones and 10 receptacles on the rear of the Power Plant Premier keep one piece of equipment from contaminating other pieces plugged into the Premier.
The Premier also has a unique feature that allows it to apply more power than it can regenerate for short periods of time. For instance, if you turn on a very large power amplifier, the turn-on power required by the amp can exceed the Premier’s regenerating capabilities. No problem, the Premier simply connects directly to the wall AC until the amplifier has powered up, then reverts back to regenerated power.
Front panel features
The front panel of the new Premier has a number of innovative features and functions not found on any other power product.
MultiWave and CleanWave
Two of the many features unique to Power Plants are their ability to produce different waveforms.
Unlike a power conditioner that simply filters, Power Plants can produce perfect
sine waves as well as modified sine waves.
MultiWaves were first introduced nearly five years ago. Invented by our good friend and Northrop Grumman engineer, Doug Goldberg, MultiWave revolutionized the AC power conditioning industry. Instead of the classic sine wave, there can be advantages to connected power supplies by changing some of the sine waves parameters.
Of all the MultiWave choices we have lived with over the years, the most consistent winner was MultiWave 1. This waveform, used in every version of MultiWave as well as AutoWave extends the charging time of the sine wave peak so attached power supplies have less ripple. In the Premier, we decided easy-was-better and offered one choice for MultiWave instead of many. To our ears, this is the clear winner.
CleanWave was introduced about a year ago and “degausses” or cleans attached equipment. It does this by varying the frequency and amplitude of the sine wave in small bubble-like responses. The Premier maintains this feature and CleanWave is available via the remote control as well as MultiWave.
