For over 33 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 20i'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 flagship power conditioner, the IT-REFERENCE 20i.
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 20i's
exclusive Discrete Symmetrical Power, video screens, projectors,
CD-DVD players, pre-amplifiers, and scalers are fed linearly-filtered
ultra-low-noise symmetrical power. This dramatically reduces AC
noise, ensuring peak operation of your critical components. For
the first time, you will see and hear your theater or audio system
as it should be — uncompromised
The IT-Reference 20i's Discrete Symmetrical Power features total
isolation between the filtered-high current outlets, and the isolated
symmetrical power AC outlet banks. This positively breaks noiseinducing
ground loops, hum bars, and power supply backwash between
critical interconnected equipment, all without compromising electrical
safety. Furman's newly refined Dual-Screen Transformers yield the
widest bandwidth of noise-reduction possible. This enables the
IT-REFERENCE 20i to uncover unprecedented levels of video and
audio detail, while insuring that plasmas, LCD screens, or video
projectors are free of AC ground contamination from an audio
processor or power amplifiers.
The IT-REFERENCE 20i also employs our unique Power Factor
Technology 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 IT-REFERENCE 20i, 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 amplifiers and
powered subwoofers to work at peak efficiency and reach 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 doubled in power
and improved immeasurably in quality.
When employing the IT-REFERENCE 20i 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 shake foundations with their weight and visceral
impact. Mid and high frequencies will bloom with sweet, non-glaring
ease while imaging improves dramatically, all the while remaining true
to your system's inherent virtues.

* Note:
Due
to the power factor correction circuit, available RMS power varies with
the reactance of the load (vector). However, this only affects the
circuit breaker for continuous RMS current draw. Since power amplifiers
will require high transient current demands, the IT-Reference 20i will
never succumb to current compression. Quite the opposite, in fact, it
will buffer the power amplifier’s power supply, while lowering the AC
input impedance, allowing power amplifiers to work more efficiently |
