PS Audio, well known for its innovative and stylish
high-performance audio and power management components at reasonable prices,
introduces the Power Plant P500 AC Power Generator, incorporating two
proprietary technologies, Multiwave IIâ and Autowaveâ. Like all Power
Plants, the P500 is designed to improve both the audio and video performance
of a Home Theater system by generating pure AC line voltage, which is
significantly cleaner than the AC voltage provided by standard wall outlets.
The P500 Power Plant produces up to 500 watts of power to amplifiers, small
projectors, LCD and plasma-based displays. Designed from the ground up, the
P500 is small in size, cool to the touch and strong enough to power and
protect an entire Home Theater system. Exclusive PS Audio technology enables
it to produce instantaneous custom waveforms - perfect for each system's
particular needs.
The P500 Power Plant features:
o MultiWave II technology with four new patterns
o AutoWave technology
o A power meter that displays wattage or percent of power available
o A built-in Ultimate Outlet and improved surge protection
o A unique computer-controlled heat reduction system
Revolutionary Power Delivery Technologies:
The P500 Power Plant produces clean AC power under ALL conditions,
dramatically improving system performance and ensuring complete protection
from surges, lightning, noise, and erratic line behavior.
The P500 introduces two new technologies - Multiwave II, a dramatic
improvement over Multiwave I, employed in current Power Plant models; and
the groundbreaking AutoWave, which automatically adjusts the P500's output
AC waveform to match the specific load in real time!
Based on the same principals of increased peak charging times, the four new
MultiWave II patterns use a random sequence of frequencies. Intermodulation
(IM) noise related to the power line is spread over a wider range, reducing
its amplitude.
The Power Plants' ability to adjust the frequency in 1 Hz steps, from 50Hz
all the way to 120Hz, to maximize system performance is innovative. No
waveform is perfect for all conditions because program material determines a
system's power demands. With the exclusive Autowave, the power output's
frequency is automatically generated to meet the exact demands of the source
material. Since A/V systems are not static, it was necessary to employ a
dynamic design that measures the changing load in real time.
A software upgrade will shortly be available to add Multwave II patterns to
other Power Plant models. Due to the complexity of the circuitry, only new
Power Plants will provide Autowave.
Accurate Power Meter:
Creating an accurate power meter is no simple task for complex loads like
those managed by power amplifiers and preamplifiers. In the original Power
Plant series the watt-meter represented the simplest expression of power by
measuring the current and the voltage, multiplying the two together to give
a close approximation of the wattage produced. However, this method is
accurate only for the simplest loads, not complex audio and video signals.
The P500's new power meter provides better than 10% accuracy, continually
measuring power and then displaying the results in either watts, or the
percentage of power the P500 has left to provide. Users can also read and
adjust the output voltage of the P500 from the meter and front panel control
systems.
Built-in Ultimate Outlet/Improved Surge Protection:
The P500 houses four standard Power Port outlets plus two high-current
Ultimate Outlets, which will power virtually any size amplifier or
projector. The P500 provides absolutely bulletproof protection for the P500
and all equipment connected to it. The Ultimate Outlet is capable of
providing up to 1800 watts of clean power.
With the P500, a whole new level of protection is brought to the Power Plant
series. Six 1.5kv Tranzorbers provide up to 9000kv of surge and spike
protection. As a secondary measure, four 10,000-amp MOVs are employed. In
the unlikely event a surge comes along big enough to overpower the
Tranzorbers, a small protection fuse opens, disconnecting a power relay to
the outputs on the rear of the P500, ensuring that all connected devices are
100% protected from transient or surge events.
A massive toroidal transformer cleanly and quietly produces the 1000 watts
needed to efficiently power the P500. Increased energy storage was also
required to provide enough power to the internal regeneration power
amplifiers and maintain the low-output impedance and exceptional voltage
regulation. The P500 is capable of regulating the output voltage to within
1/10th of a volt from idle to full output current.
Unique Forced-Air, Computer-Controlled Heat Reduction System:
The P500 is housed in the same elegant rack-mountable chassis as the recent
HCA-2 Hybrid Digital/Analog Power Amplifier and PCA-2 Preamplifier - both of
which always remain cool to the touch due to PS Audio's exclusive internal,
forced-air, computer-controlled heat reduction system.
Power Plants are basically high-powered class AB power amplifiers, which are
known to generate a great deal of heat. Instead of external heat sinks,
which are impractical for rack or shelf mounting, a tunnel heat sink was
designed. This is an enclosed set of aluminum heat fins with a fan to blow
air over them. The tunnel air movement is adjustable and in synch with the
temperature of the heatsink. Thermal sensing devices along the heatsink are
connected to a microprocessor that precisely controls the "whisper fan"
inside the P500.
The P500 Power Plant is available for a suggested price of $1,995. For
