Warranty inside the U.S. and

Canada

PS Audio’s warranty is 3 years parts and
labor, from the date of original purchase.
This means that we warranty the product
itself regardless of ownership, new or used.

Warranty outside the U.S. and

Canada

PS Audio has authorized distribution in
many countries of the
world. In each country,
the authorized importing
retailer or distributor has
accepted the responsibility
for warranty of products
sold by that retailer or
distributor. Warranty
service should normally be
obtained from the importing
retailer or distributor from
whom you purchased the
product. In the unlikely
event of service required
beyond the capability of
the importer, PS Audio will
fulfill the conditions of the
warranty. Such product

must be returned at the owner’s expense to
the PS Audio factory. Contact your PS Audio
distributor or the PS Audio customer service
department for more information.

Service issues

Should your unit ever require service or
if you have any technical questions about
the Power Plant, you must either contact
your dealer (PS Audio if purchased direct)
or your PS Audio distributor. No equipment

will be received at our
service facilities without an
attached RA number.

If purchased through
an authorized PS Audio
dealer or distributor, the
RA number must be
obtained by the dealer or
distributor. If the product
was purchased from PS
Audio direct, this can
easily be obtained by
contacting PS Audio at:

Warning

To prevent fire or shock hazard, do not
expose the Power Plant to rain or mois­ture. To avoid electrical shock, the Power
Plant must be unplugged and fully dis­charged before opening.

To prevent electric shock, use a 3 prong,
grounded type power cable.

Any change or modifications not expressly
approved in the manual could void your
warranty.

Safety Instructions

Retain the operating instructions for later
use and reference

Unplug the Power Plant from the wall outlet
before changing the fuse or performing any
upgrade or service.

Do not operate the Power Plant near water.
Avoid placement near a water reservoir or
excessive moisture.

When replacement parts are required, be
sure they are specified by the manufacturer
to have the same characteristics as the orig­inal. Unauthorized substitutions may result
in fire, electric shock, or other hazards.

Do not operate with faulty or frayed power
cables.

Overview

The benefits Multiwave II will provide for
your power plant are:

• MultiWave II and TubeWave waveforms.

• More accurate sine wave generation.

• Lower distortion

• Servo control system for consistent DC
output over time.

MultiWave II Operation

Notice of MultiWave II operation:

Any tu rntable or equipment with AC
synchronous motors, such as some cooling
fans should not be used with MultiWave
patterns. This type of equipment must be
used with 60Hz sin mode.

We recommend the use of the sine wave
[sin], or TubeWave™ [tub] with any type of
tube based audio products.

There are five available display modes on
the front panel of the Power Plant. The
Mode button will cycle through the following
five modes:

1. Waveform setting

2. Frequency generated (sin mode only)

3. Voltage produced

4. Wattage produced

5. Display blanking mode

Waveform setting

This mode will display the name of the
waveform presently being generated.
For more information about each of the
MultiWave settings, see the Multiwave II
Waveforms section of the manual.

Frequency generated

The frequency setting will only be displayed
if the Waveform menu is set to Sin.

This mode will display the frequency the
Power Plant is generating. The frequency
can be adjusted in 1 hertz increments from
50Hz to 120Hz by using the Up and Down
buttons. The default setting is 60Hz.

Voltage produced

This mode will display the output voltage of
the Power Plant. Note: the voltage figure
will be flashing. The output voltage can be
adjusted in 1 volt increments by using the
Up and Down buttons. The range varies
depending on the Power Plant model:

• 100 volt model ranges from 95 - 105 v.
Default setting is 100 volts.

• 120 volt model ranges from 100 - 120 v.
Default setting is 117 volts.

• 240 volt model ranges from 220 - 240 v.
Default setting is 240 volts.
(adjustments in 2 volt increments)

2

As long as the voltage to the Power Plant
does not deviate more than 10% below
normal it will continue to output the voltage
displayed on the front panel.

Wattage produced

This mode will display, in real-time, the
approximate wattage the Power Plant is
generating. Complex loads may not register
accurately on the Power Plant's meter. For
true power consumption figures consult the
owners manual of the connected product.

Under normal operation a green LED will
illuminate. A yellow LED will indicate a
heavy load and is not recommeded for
continous operation. A red LED indicates an
overload or fault mode.

Display Blanking

This mode allows discrete front panel
operation by blanking the display. The PS
logo will continue to illuminate in blue to
indicate that the unit is operational.

MultiWave II Waveforms

[sin] sine wave

In the sine wave mode the Power Plant will
generate a perfect sine wave (50-120Hz).

[tub] TubeWave

TubeWave is specifically designed to opti­mize the performance of tube based audio
products.

TubeWave uses the same pseudorandom
generation of frequencies as MultiWave2
waveform, however it generates more tube­friendly frequencies.

[P-1] MultiWave1

MultiWave1 is a single 60Hz sine wave
with a minute amount of 3rd Harmonic
sine waves mixed together to form a
single partial square MultiWave. This is an
improved version of PS2 from the original
MultiWave™ series.

The partial square wave setting improves
the power supply’s ability to charge the
capacitors in equipment by extending the
length of time available to "top off" the
capacitors' voltage. Use this setting to
enhance the performance of both source
and power equipment.

[P-2] MultiWave2

MultiWave2 is a 60Hz sine wave that
incorporates a pseudorandom collection
of frequencies which are dithered from 55­65Hz.

Using this slightly random frequency
deviation is similar to adding dither on a
digital audio source. Power supply dithering
can lower the perceived noise floor and help
remove apparent glare on the audio signal.

[P-3] MultiWave3

MultiWave3 is a combination of Multiwave1
with a slight degree of 3rd harmonic addition
(MultiWave1).

Try this setting and see how the audio
sounds and the video looks. All systems
can respond differently to each MultiWave
pattern.

[P-4] MultiWave4

MultiWave4 is full combination of
MultiWave1 and MultiWave2. It generates
a pseudorandom collection of frequencies,
however instead of generating sine waves
it generates the same waveform as
MultiWave1.

Again, try these setting on your system to
see which one has the highest perceived
benefit in terms of performance.

Servo System

MultiWave II provides a virtual Servo
System to continually correct for any DC off­set. This will reduce hum from problematic
or sensitive transformers as the Power Plant
produces pure AC waveforms indefinitely
without the need for calibration.
