Elite 20 PF owner’s manual
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
power is nothing new, the Elite-20 Power Factor’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.
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.
Another critical feature is our exclusive
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
At the center of the Elite-15 PF is our unique
Power Factor Correction Circuit. For the first time,
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.
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
