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 stable AC power is nothing new, the
SPR-20i's technology and its unique implementation is revolutionary.
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 SPR-20i.
With today's chaotic demands on many municipal power facilities, AC
voltage is often reduced so that it can be stretched to fulfill excess demand.
This creates a substantial negative impact on your system's performance.
Power amplifiers and powered sub-woofers cannot perform to their full
potential. Even a relatively modest reduction in AC voltage can obliterate
the sonic impact of an otherwise superior system. Just as problematic
are excessively high line voltages. Excess voltage can overheat sensitive
circuits; lower the life and reliability of projector lamps, and cause many
circuits to shut down. With the SPR-20i's exclusive Stable Power AC Voltage
Regulation Technology, voltage-starved power amplifiers and powered
sub-woofers perform at their full potential. With the SPR-20i, home theaters
are supplied with constant, virtually unwavering AC voltage. This assures
trouble-free service for any environment suffering from unstable power.
The SPR-20i generates virtually no heat, and produces none of the
mechanical noise typical in inferior AC voltage regulators. Further, our
zero-crossing solid state technology provides virtually unlimited peak
current delivery, avoiding the current limiting found in AC regulators
that convert AC power into DC, then synthesizing an AC output signal.
In addition to unstable voltage, today's AC 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 Linear Filtering Technology,
televisions, projectors, DVD players, and processors are fed linearly-filtered AC
power. This dramatically reduces noise, ensuring consistent peak operation of
your critical components regardless of load conditions or the time of the day.
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 digital AC
input voltage, output voltage, and current meters allow precise measurements
of both the AC line and the current load. These meters are valuable assets
when monitoring systems that are connected to today’s potentially poor power grids.
When employing the SPR-20i, you will 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. When installed with the
IT-Reference 15i or 20i, home theaters will reap the dual benefits of Furman's
Stable Power and Discrete Symmetrical AC Filtering, ensuring performance
without compromise — without peer.
