IT-REFERENCE 20 OWNER’S MANUAL
Introduction
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 IT-Reference 20’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 our fl agship power
conditioner, the IT-Reference 20.
Today’s AC lines are plagued with ever
increasing noise. When AC noise couples into
your system’s critical components, it masks
low level signals and cripples performance.
This low level content is critical because it
relays the crucial harmonics and ambience
in audio, and depth and clarity in video. With
the IT-Reference 20’s exclusive Discrete
Symmetrical Power, video screens, projectors,
CD-DVD players, pre-amplifi ers, and scalers
are fed linearly-fi ltered ultra-low-noise
symmetrical power. This dramatically reduces
AC noise, ensuring peak operation of your
critical components. For the fi rst time, you will
see and hear your theater or audio system as
it should be – uncompromised.
Further, our Discrete Symmetrical Power
features total isolation between four discrete
AC outlet banks. This positively breaks noise-
inducing ground loops, hum bars, and power
supply backwash between interconnected
equipment, all without compromising electrical
safety. This enables a plasma screen to
function without AC ground contamination
from a compact disc player, or a preamplifi er-
processor to function free of performance-
degrading digital noise from a satellite receiver.
The IT-Reference 20 also employs our unique
Power Factor Correction Circuit. For the fi rst
time, low-level analog, digital, and video
components are not modulated or distorted
via the power amplifi er’s extreme AC current
demands. Further, the power amplifi er sees
a highly fi ltered, extremely low-impedance
supply of AC power. The IT-Reference 20, in
fact, has in excess of 9 Amps of continuous
current reserve (over 80 amps peak charge)
for the most extreme peak power demands.
This technology enables power amplifi ers and
powered subwoofers to work at peak effi ciency
and reach levels of performance previously
unattainable.
No longer will your amplifi er’s performance
be at the mercy of your home’s incoming AC
power or inferior AC protection/fi ltering devices.
The net effect is as if your power amplifi er
doubled in power and improved immeasurably
in quality.
When employing the IT-Reference 20 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
defi nition, as well as noticeably improved depth
and clarity. Sonic transients will be startlingly
