Thank you for your purchase of a PS Quintessence Power
Center.
The Quintessence Power Center is a state of the art AC
power conditioner producing clean and protected AC
power. TheQuintessencePowerCenterhasarevolutionary
new filter inside that cleans the AC power all the way into
the audio frequencies. Before the Quintessence, passive
power conditioners were restricted to 50kHz and above.
Now, with the Quintessence Power Center, cleaning of
noise from the AC line occurs at frequencies down to
2kHz! Clean AC is essential to optimize the performance
of your connected equipment.
The Quintessence Power Center will not restrict dynamics
or soundstage in any high-end system and will, in fact,
provide a superior level of performance in micro and macro dynamics as well as maintain harmonic
integrity for audio equipment while increasing color saturation and lowering video noise in video
equipment.
On the rear of the Quintessence Power Center, the cleaned AC voltage is distributed to your equipment
through 5 isolated zones that utilize a new magnetic filtering technology based on wound inductors
built from strips of Nano Crystalline high
permeability soft magnetic material.
This material has approximately
10 times higher permeability than
any other magnetic materials ever
produced. High permeability magnetic
core materials allow PS Engineers to
use a minimal amount of copper wire
to build effective filters, thus preserving
micro and macro dynamics for both
audio and video systems.
PS power products are built to the
highest standards internally and
externally and feature ¼ inch thick
solid copper power bars, heavy
extruded aluminum covers and nickel
plated, hand polished Power Port AC
receptacles as standard equipment.
The Quintessence Power Center should provide years of trouble free performance for your connected
equipment with the peace of mind they will be fully protected.

Owner’s Reference Quintessence Power Center
Once your new Quintessence Power Center is unpacked, you’ll need to find a convenient place to
set it.
There are several ways to mount the Quintessence Power Center: on a shelf, or in a rack. If you are
placing the Quintessence Power Center in a rack, you can use the supplied rack ears or you can use
a rack shelf. The Quintessence Power Center does
not generate heat so concerns of airflow and heating
of other equipment are not necessary.
If you are rack mounting the Quintessence Power
Center is supplied with a set of rack ears that can be
mounted to the Quintessence Power Center.
If your equipment is located a long distance from the
Quintessence Power Center, it is preferable to use
a long, heavy gauge shielded power cable between
the wall AC receptacle and the Quintessence Power
Center, rather than long individual power cables
between the equipment and the Quintessence
Power Center.
The Quintessence can benefit from aftermarket isolation devices such as cones, spikes and
Sorbothane pads.
Once you have chosen the location for the Quintessence Power Center you can use the supplied AC
power cord to connect it to the AC wall receptacle or you can use an aftermarket power cord and
receptacle.
We strongly recommend the use of a PS Audio xStream Power™ AC cable and a PS Power Port™
AC receptacle, or Soloist AC receptacle to feed
the Quintessence Power Center electricity.
While the supplied power cable is adequate
for the task, it is not going to provide the best
performance. Choosing any xStream Power
cable will make a significant performance
improvement over the stock power cable.
We recommend the use of the Soloist in-wall AC
receptacle to feed power to the Quintessence
Power Center. We, however, discourage the
use of any other power conditioning equipment
before or after the Quintessence Power Center
without considerable evaluation to determine
if there are any sonic or visual shortcomings of doing so. The Quintessence Power Center has
a significant input and output passive filter design and adding extra power cables to its input or
additional filtering to its output may, in fact, be less than desirable.

We would recommend that you power the entire system down before attempting to connect equipment
to the Quintessence Power Center.
Plug the Quintessence Power Center into an AC receptacle with at least 15 amps of service (in the US)
or 7.5 amps of service (in 220 volt countries), preferably using a dedicated AC line. A dedicated line
means there is nothing else plugged into the wiring feeding the AC receptacle and that wiring returns
directly to the AC breaker box.
Our first recommendation on where to connect your new Quintessence Power Center would be a PS
Soloist in-wall device. The Soloist provides the first stage of cleaning and protection in the PS Power
System and is an elegant in-wall solution that does not use an additional power cable. Our second
choice is a PS Power Port AC receptacle. While not as good as a Soloist it is certainly preferable to a
$1.99 “contractor special” brass contact AC receptacle found in most of our homes.
Use the heaviest gauge shielded AC power cable you can to connect a Quintessence Power Center to
its AC source. The heavier the gauge used, the less the chance for restricted dynamics in both audio
and video systems. The PS display will blink when you first power the Quintessence Power Center.
This is normal.
Once the Quintessence Power Center has been connected to an AC source it is time to connect your
equipment. Each Quintessence Power Center has multiple isolated zones called IsoZones™. These
are individually isolated and filtered zones that isolate the power between equipment.
IsoZones should be used to isolate different
genres of equipment from each other. For
instance, you can group digital equipment
together on a single IsoZone or multiple
analog sources on yet another IsoZone.
You should not mix digital, video or analog
equipment on the same IsoZone if possible.
Digital equipment would be a DVD player,
CD player, DAC, computer, TIVO, or satellite
receiver. Video equipment would be a VCR,
TV or computer monitor. Analog examples
would be a power amp, preamp, projector,
turntable, or any type of tube equipment. On
the Quintessence Power Center, IsoZone 5
is labeled Power Amp. It is no different than
any of the other 4 IsoZones, other than it is a single duplex receptacle to keep the heavy current draw
of power amps from affecting more sensitive source equipment.
It is important to use only the highest quality AC power cords that are well shielded to any connected
equipment. It is a good idea to keep in mind that all equipment generates radiated noise when it is
operating. This radiated noise is harmful to both audio and video system performance and is typically
carried down the AC power line.

The Quintessence Power
Center has selectable Power
Zone switching. Each of the 5
IsoZones on the Quintessence
Power Center are controlled by
one of three Power Zones labeled
A, B and C. Acontrols IsoZones
1 and 2, Bcontrols IsoZones 3
and 4 and Ccontrols IsoZone 5
(labeled Power Amp).
Each of the three Power Zones
can be set to one of three
positions: always on, switched
and delayed.
Always on. The front panel
power button (PS blue logo) or rear panel DC triggers will have no effect on any Power Zone switched
to this position. Anything plugged into a receptacle will be immediately connected to the AC power.
Use this setting for equipment you never want to turn off from the Quintessence Power Center’s main
power button. Examples would be a computer or a TIVO (so it can record a preset program when the
system is shut off) or another piece of equipment used for a trigger voltage.
Switched. The power button on the Quintessence Power Center (PS blue logo) or the DC triggers will
activate or deactivate any equipment plugged into a receptacle set to “switched”. This is the standard
default and recommended switch setting for any source equipment plugged into the Quintessence
Power Center. These outlets will be delayed on turn off to give the power amplifier time to shut off.
Delayed. After the power button is pressed or the trigger is activated on the Quintessence Power
Center, these outlets will be delayed by 3 seconds before turning on. Use this setting for power
amplifiers or any equipment that should turn on after the Quintessence Power Center’s switched
outlets are activated. This outlet will do the opposite on shut down. It will be the first to be turned
off.
DC triggers on the Quintessence Power Center are used to remotely turn on and off the Quintessence
Power Center. These will accept any voltage from 5 to 15 volts. If your equipment produces a DC
trigger voltage, use this input to control the Quintessence Power Center.
The CATV and telephone protection inlets found on the Quintessence Power Center are high quality,
no-loss in/out paths for protection. The CATV connectors can accommodate two sources such as a
cable TV or a satellite or antenna feed.
Once everything is connected you can press the front panel blue PS logo light which will act as the
on/off power button if you are not using the DC triggers or do not have the Always On switch position
activated on the rear of the unit.

The front panel of the
Quintessence Power Center has
three function buttons, located
just below the display. It has
two display modes that can be
accessed from the front panel or
remote control including: voltage
and THD.
From left to right as you face the
unit, the functions are mode up,
mode down, display.
Mode buttons are used to scroll
through the display options.
Display options include, voltage
and THD (Total Harmonic
Distortion).
Each mode has an associated
function indicator that will light up
to indicate the display function you
are on.
The default display position is
Voltage In. This shows the voltage
coming into the Power Plant from
the AC wall socket.
The next position is the Incoming THD measurement. This measures the percent of harmonics
present on the incoming AC line. Typical in a home is between 2% and 5%. Harmonics are
generated by distortions in the AC waveforms, clipped top of the sine wave and added noise. These
are undesirable.
The Quintessence can not improve or repair the distorted AC sine wave. Only a Power Plant AC
regenerator can do that. The Quintessence will, in fact, clean anything above 2kHz, including some
harmonic distortion. However, the analyzer built into the Quintessence is limited to approximately 1
kHz.
The display button on the far right side of the Quintessence Power Center has three positions that
control display brightness. Full, half and off.
MultiWave and CleanWave are functions exclusive to the Power Plant. The remote we use is
applicable to both the Power Plant and the Quintessence. However, while the remote shows “MW”
(MultiWave) and CleanWave buttons, they are inoperative on the Quintessence.
There are two buttons on the remote labeled “Edit”. These are not used on the Power Plant and are
there for future products and features.

The Quintessence Power Center is best left plugged in to the AC source at all times. The current
draw is negligible and keeping it powered on will make sure the internal components stay working
properly.
There is no harm in leaving the unit on at all times as the lifespan of the Quintessence Power Center
will be unaffected by leaving it on.
There are no user replaceable
internal fuses inside the
Quintessence Power Center.
There is an externally accessible
circuit breaker right next to
where the AC plug is connected
to the Quintessence Power
Center. Simply push the button
on the circuit breaker should it
be tripped. The components
inside the Quintessence Power
Center have lethal voltages when
powered and even when un-
powered. Capacitors inside the
Quintessence Power Center can
retain an electrical charge after the
unit has been powered down. Do
not attempt to get inside the unit for any reason unless instructed to do so by your dealer or an
authorized service representative. Should the Quintessence Power Center cease to function, check
the circuit breaker and if that fails, contact your dealer or PS Audio’s service center for help.
Placement of the Quintessence Power Center is important with respect to good ventilation. Placement
with respect to other equipment can be important as well. In general, place the Quintessence Power
Center close to the equipment you wish to power. It is always preferable to have a long heavy gauge
power cable feeding the Quintessence Power Center if there is a distance problem.
Isolation through the use of spikes, cones or Sorbothane feet is recommended for the Quintessence
Power Center if space and budget allows. Isolation of any piece of high-end stereo and theater
equipment is always recommended wherever practical.
Yes, cables make a difference. It is important to use the best power cables possible. Remember that
everything you see and hear in an AV system is nothing more than the power from the wall modulated
by a CD, DVD, turntable or tuner. You are actually “listening or viewing” the AC power. So it is critically
important to connect your equipment with the heaviest gauge well shielded power cables you can
afford. Power is the foundation of everyone’s system.

Quintessence Power Center. Look for the company logo and press it.
You do not have to use the Power Amp IsoZone on the Quintessence Power Center for a power amp.
It is marked like this for convenience.
All IsoZones are identical in build and all use our new Nano Crystalline soft magnetic material to clean
the AC power.
You can plug the Control Center into a 15 amp or 20 amp receptacle without any problems (half of
that current in 220 volt countries).
MultiWave and CleanWave are not available on the Quintessence Power Center even though they are
indicated on the Remote Control.
The front panel metering system can
monitor either voltage or distortion. In
the voltage mode, you can monitor the
incoming voltage (from the wall). In the
THD harmonic distortion mode, you can
monitor incoming THD (from the wall).
The output frequency of the Quintessence
Power Center is the same as your country’s
AC frequency. In North America, the
frequency of the AC line is typically 60Hz.
In Europe and Asia, the output frequency
is typically 50Hz. The Quintessence
Power Center’s output frequency cannot
be adjusted.
The Quintessence Power Center is specific to your country’s voltage. Do not use the Quintessence
Power Center on a voltage higher than it is rated for. For instance, do not take a 120 volt rated
Quintessence Power Center and attempt to use it in a 230 volt country. Failure to observe this
cautionary note will void your warranty and may damage the Quintessence Power Center. If you need
to operate the Quintessence Power Center at a voltage other than the voltage it was designed for,
contact your dealer, distributor or the factory.

If no power comes out of the Quintessence Power Center, check to make sure power is going into
the Quintessence. You can do this by testing the outlet it is plugged into with another device such
as a lamp. Sometimes, we find customer equipment plugged into switched wall outlets. These are
typically the lower of the two AC receptacles and are controlled by a light switch. If you have no
power to the receptacle, check that it is not a switched outlet and then if the circuit breaker feeding
the receptacle is good.
If you have verified there is power to feed the Quintessence Power Center, check the Quintessence
blue front panel PS logo to see if it is lit. If not, press the logo itself. This is the power button. Check
and make sure there are no connections to the triggers. Pull them out if there are. If the logo does
not light, check the circuit
breaker next to the AC inlet
on the Quintessence Power
Center. Press the circuit
breaker to activate.
Lastly, make sure you are
feeding the Quintessence
the correct voltage. The
Quintessence Power
Centers are specific to
your country’s voltage.
If, for example, you are
trying to operate at 120
volt Quintessence Power
Center on 220 volts, it will
not turn on. If all else fails,
contact your PS dealer,
distributor or PS directly for
help.
If the blue logo power button blinks or the display shows bars when you first plug in the Quintessence
Power Center to an AC receptacle, this is normal. The unit is calculating the voltage being fed to it.
If the remote control does not operate, check for proper battery insertion and make sure there are
fresh batteries in the unit.
If the trigger circuit is not working, check to make sure you are feeding it proper voltage. The trigger
circuit requires 5 to 15 volts positive. You can test the trigger circuit with a simple 9 volt battery.
Connect the minus of the battery to the outer ring of the trigger input mini jack and the plus to the “tip”
or center of a male mini jack. The 9 volt battery will provide the proper voltage to operate the trigger.
When power is applied, the Quintessence Power Center will turn on. When power is removed, the
Quintessence Power Center will turn off.

If you experience a hum through the speakers once the Quintessence Power Center is powering
your equipment this can be caused by several things. The first is the source. If there is an excessive
amount of buzz or noise from the loudspeaker, it may be caused by a ground loop, a light dimmer in
the home, poor AC power, or any number of causes. The quickest way to determine where to start
your search is to simply turn
the preamplifier, integrated,
receiver or Control Amplifier
off, disconnect the audio
cables between it and the
sources, and see if the hum
goes away when you turn
the preamplifier, integrated,
receiver or Control Amplifier
back on. If it does, it’s most
likely a ground loop or buzz
from a dimmer.
If this doesn’t solve the
problem, follow these easy
humbusting tips.
The easiest way to figure out
where ground loop problems lie is by the process of elimination. You need to determine where the
hum or buzz is coming from within your system.
If the hum/buzz goes away when you remove the inputs to the power amp, your next step will be
to reconnect the amp and move further down the chain. If you were working with a receiver or an
integrated amplifier, you will need to jump to step 4. If you have a preamp, or processor that is feeding
the power amp, your next step would be to disconnect all inputs to the preamplifier or processor. Once
these are disconnected, and the preamp or processor is connected only to the power amplifier, turn
the system on and again, listen for hum. Should the hum now appear, it is a problem with your preamp
or processor or their interaction with the power amp. Before returning the preamp or processor to
the manufacturer, try a cheater plug to break a ground loop. Cheater plugs are simple devices that
convert a three prong AC plug into a two prong AC plug and in the act of converting three prongs, to
two prongs, they disconnect the ground from the wall socket. Try one of these on the preamp, or the
power amp, or both.
If you determine that there is still no hum present when the preamp, processor or receiver is
connected with no inputs, then selectively begin plugging in your various inputs one at a time. After
each connection, check for hum until you discover the humming culprit.
VCR’s, surround processors, and any device that is connected to a television cable or satellite dish
can cause a loud buzz and should always be suspect. If, by the process of elimination described
above, you determine it is a component like a VCR that is causing the hum/buzz to occur, and using
a cheater plug or removing the ground pin on a PS xStream Power Cable doesn’t help matters, it may
be necessary to isolate the cable connection (CATV) with an isolation transformer.

This inexpensive device is
available at most Wal Mart, Radio
Shack or department store type
outlets and is sometimes called
a ‘matching transformer’. If you
have problems finding one, call
your local cable TV company for
advice. The matching transformer
will be placed between the cable
TV cord and the VCR, TV or
processor.
Just remember, take the system
down to its simplest level of
connection.
Find a way to hook the system up
with as many pieces of the system
missing or not connected.
Keep it simple and get it to the point where the hum’s gone. Then start adding back components one
at a time until the hum returns.
Finding the problem is 9/10th of the work in finding a solution.
