Another critical feature is our exclusive  
introduction  
Series Multi-stage Protection. This virtually  
maintenance-free surge suppression assures  
the highest level of AC protection possible,  
without sacrificing itself when the offending  
surge is severe – no damaged equipment,  
no service calls, no down time. Further, our  
famous retractable front panel LED lamps allow  
easy viewing of either a rack or cabinet full of  
equipment, even when your theater lights are  
off.  
For over 30 years, Furman has pioneered the  
development of AC power products for the  
most demanding audio, video, and broadcast  
professionals. Though the need for pristine AC  
powerisnothingnew,theElite-20PowerFactor’s  
technology and its unique implementation are  
revolutionary and without peer.  
The extreme AC demands encountered in the  
professional audio/video arena have required  
technological developments far in excess of  
typical home theater/audiophile power products.  
In studios, live sound, and broadcast facilities,  
breakdown is unacceptable. Equipment failure  
or poor performance is costly. The same is true  
of today’s home theater. Our solution based  
technology, extensive engineering expertise,  
and robust build quality have answered the  
challenge of today’s corrupted power lines, and  
led to the creation of the Elite-20 PF.  
At the center of the Elite-15 PF is our unique  
PowerFactorCorrectionCircuit. Forthersttime,  
low-level analog, digital, and video components  
are not modulated or distorted via the power  
amplifier’s extreme AC current demands.  
Further, the power amplifier sees a highly  
filtered, extremely low-impedance supply of AC  
power. The Elite-20 PF, in fact, has in excess  
of 4.5 Amps of continuous current reserve (over  
55 amps peak charge) for the most extreme  
peak power demands. This technology enables  
power amplifiers and powered subwoofers to  
operate at peak efficiency, reaching levels of  
performance previously unattainable.  
Today’s power lines are plagued with RF  
and EMI noise. When connecting sensitive  
equipment to your home’s power outlet, AC  
noise couples into your system’s critical  
components. This AC noise masks low level  
signals and cripples performance. This low level  
content is critical because it relays the crucial  
harmonics and ambience in audio, as well as  
the depth and clarity in video. With Furman’s  
exclusive Ultra-Linear Filtering Technology,  
televisions, projectors, DVD players, amplifiers,  
and processors are fed ultra-wide bandwidth  
linearly-filtered AC power. This dramatically  
reduces noise, ensuring consistent peak  
operation regardless of load conditions or the  
time of day. For the first time, you will see and  
hear your theater or audio system as it should  
be – uncompromised.  
No longer will your amplifier’s performance be  
at the mercy of your home’s incoming AC power  
or inferior AC protection/filtering devices. The  
net effect is as if your power amplifier virtually  
doubled in power and improved immeasurably  
in quality.  
When employing the Elite-20 PF, you will  
immediately notice far clearer, stunningly  
focused sound and visual images from your  
system. Video presentation will be crisp and  
colors true with greater gray and black scale  
definition, as well as noticeably improved  
depth and clarity. Sonic transients will be  
startlingly fast with bass fundamentals that

Do not allow liquids or foreign objects to  
enter the unit  
The Elite-20 PF should be serviced by qualified  
service personnel when:  
installation:  
The power supply cord or plug has been  
frayed or cut.  
unpacking  
Before unpacking your unit, inspect the carton  
for any obvious severe damage to the box and  
internal protective materials. If internal damage  
is likely, contact the carrier who delivered the  
unit before proceeding with unpacking. If, after  
unpacking, shipping damage is evident, contact  
the carrier. Save all shipping and packing  
materials. You may need them if you should  
ever have to return the unit to the factory for  
servicing.

other moisture.  
The Elite-20 PF does not appear to operate  
normally, or exhibits a marked change in  
performance.  
The Elite-20 PF has been dropped, or the  
enclosure damaged.  
The Elite-20 PF requires that a safety ground  
be present for proper operation. Any attempt to  
operate the Elite-20 PF without a safety ground  
is considered improper operation and could  
invalidate the warranty.  
The box should contain the Elite-20 PF unit,  
detachable AC cord, rack mount kit, owner’s  
manual,andwarrantyregistrationcard. Ifanything  
is missing, please contact Furman Customer  
Service. Fill out and return your warranty  
registration card. Registration is recommended  
because it can be used to establish whether the  
unit is within the warranty period should your  
original ownership documents be lost, and it  
assists us in informing you about upgrades or  
other vital information.  
Power source  
The power source to which the Elite-20 PF is  
connected should be adequate for use at 20  
Amps. The Elite-20 PF will operate with a 15  
Amp service outlet; however, nuisance tripping  
at the circuit breaker panel may result if the  
systems continuous current draw exceeds 15  
Amps.  
safety information - warnings  
Please read and observe all of the safety and  
operating instructions before the Elite-15 PF is  
operated. Retain these instructions for future  
reference.  
Placement  
The Elite-20 PF is manufactured with four  
rubber feet for placement on any table, cabinet,  
shelf, or floor. These rubber feet may be

components. Placement or proximity to other  
components is not critical, and the Elite-20 PF  
does not produce any appreciable heat under  
standard use. The Elite-20 PF may also be rack  
mounted in a standard 19” rack by attaching  
the Elite-20 PF rack ears. These rack ears  
(contained within the plastic rack kit package)  
mount flush with the back portion of the Elite-  
20 PF’s front panel. They are attached to the  
chassis by installing each rack ear with (3) pan-  
head Philips screws contained within the Elite-  
20 PF rack mounting kit. The third screw used  
for each rack ear is for the center hole, located  
towards the rear and aids in stabilizing the unit  
when rack mounted.  
connected to the “Ultra-Linear VideoAC Outlets,”  
with the exception of receivers, power amplifiers  
and powered sub-woofers.  
These outlets  
possess the same exceptional AC noise filtering,  
and provide additional inter-component noise  
isolation to maximize system performance.  
Connecting Components to the High Current  
Power Amplifier Banks  
All power amplifiers, receivers and powered  
sub-woofers should be connected to these four  
outlets.  
Many Audiophile and premium Home Theater  
systems will have combined continuous current  
demands below 20 Amps. It is rare, in fact, for  
large power amplifiers to draw more than 4  
Amps continuously. For superior performance,  
it is vital that an AC filter possess extraordinarily  
low impedance, and have the capability to pass  
peak current demands far in excess of the RMS  
(continuous) current rating.  
The Elite-20 PF was designed to more than meet  
this demand. Additionally, our Power Factor  
Correction Circuitry effectively creates a current  
reserve in excess of 55 amps peak charge that  
is cleaner and faster than a dedicated line from  
your local power station. This feature eliminates  
any concern towards the current compression  
that can result from typical power conditioners,  
and the peak power reservoir benefits any power  
amplifiers performance dramatically.  
Connection:  
aC Cable routing  
Once the Elite-20 PF is placed, its AC cord’s  
female end must be plugged into the male IEC  
connector located on the lower left hand side  
of the rear panel (when facing the rear panel).  
Next the male Edison plug must be connected  
to an appropriate socket (see current rating  
recommendation above).  
Connecting Components to the ultra-linear  
Filtering Video aC outlet Banks  
The Elite-20 PF’s four “Ultra-Linear Video AC  
Outlets” should be employed for critical video  
components such as DVD players, projectors,  
plasma, or LCD video screens. When employing  
the Elite-20 PF for a 2-channel audio system,  
a SACD player for example would be ideally  
suited for one of these outlets.  
Note about Power Factor Correction and Current  
Consumption:  
When power correction technology is employed  
with even the most sophisticated circuit breakers,  
it effectively adds to the perceived current load.  
Though the Elite-20 PF was designed for steady  
20 Amp operation, and peak current demands  
many times that, the maximum total continuous  
current draw may be limited to a range between

and power will not be applied to the unit’s outlets.  
If the unit has been operating with an acceptable  
input voltage and subsequently that voltage  
exceeds 137V, it will shut off power to the outlet  
and the Extreme Voltage LED will light.  
All in-line surge suppressors feature our exclusive  
ground contamination free technology. This aids in  
eliminating audio buzzing, and the video hum-bars  
that can result from typical in-line suppressors.  
Further, our cable and satellite suppressors are  
TIVO friendly as well as HD-Digital Television ready.  
Both DC carrier signals as well as high bandwidth  
signals can pass through our circuit. In fact the  
bandwidth is less than 0.1dB loss at 1GHz!  
Protection OK Indicator:  
Although the Furman SMP circuit assures  
virtually maintenance free protection from  
transient voltage spikes and surges, nature has  
a way of occasionally creating electrical forces  
that are beyond the capabilities of any Transient  
Voltage Surge Suppression device to absorb  
without some degree of damage. In the rare  
instance that this occurs, the blue LED located  
in the center of the front panel will dim, even  
though AC power is present at the unit’s outputs.  
If this happens, some level of protection from  
voltage surges will remain, but the Furman’s  
clamping voltage rating will be compromised.  
The unit must be returned to Furman Sound, or  
an authorized Furman Service center for repair.  
To connect your cabling to these in-line protectors,  
simply follow the in and out indications marked  
next to the Telco, Cable and Satellite connectors.  
Note: It is not possible to make an a telco  
(telephone –line), satellite or cable protector  
“maintenance-free” as we have accomplished with  
the 120 VAC line. This would necessitate limited  
signal bandwidth that would not allow the signal  
to pass. Under extreme conditions, it is possible  
that the surge suppression in one of these  
devices could sacrifice itself after a catastrophic  
event. If the telephone, cable or satellite signal  
will no longer pass through our protector, please  
contact your local service representative, installer  
or Furman for servicing. Since the telco circuit  
is modular, replacement may be accomplished  
in seconds with a new telco TVSS module. To  
test this, simply disconnect the incoming and out  
going phone line from the Elite-20 PF. Connect  
the incoming connector to the component that  
formerly received the out going connector, thus  
by-passing the in-line protection. If the signal is  
present (but not when used with the Elite-20 PF)  
then the protection circuit is damaged (assuming  
it worked properly before a storm or catastrophic  
event). With Cable or Satellite protection, it is  
HIGHLY unlikely that the protection device will  
ever fail unless a severe lightening strike literally  
deforms the connector. If this occurs, return to  
Furman Sound for Servicing.  
NOTE: If the mains power is above the high  
cutoff voltage and has caused the unit to remove  
power from its outlets, it cannot restore power  
without the operator manually turning the unit  
off, then on again. Avoid turning the unit back on,  
without first checking the source of the problem,  
and perhaps changing the AC source.  
telco – satellite – Cable transient Voltage  
surge suppressors  
The Elite-20 PF features transient voltage  
surge suppression for both standard telephone  
lines, as well as cable or satellite lines utilizing  
standard coaxial connectors. As these surge  
suppressors are in-line, they will require an  
additional cable to connect from their output to  
the control device requiring protection.
