Features
Stable Power: The SPR-20i's exclusive Stable Power AC Voltage
Regulation Technology maintains 120 volt AC output with higher and lower voltage
inputs, allowing power amplifiers and powered subwoofers to perform at their full
potential. Using the SPR-20i, your home theater is supplied with constant, virtually
unwavering AC voltage. Fuman's zero-crossing solid state technology provides 60
amps peak current, avoiding the current limiting found in AC regulators that convert
AC power into DC, then synthesize an AC output signal.
EMI and RFI Filtration: EMI and RFI noise entering your A/V
system through the AC power line couples to the components and masks low level
signals, compromising performance. This low level content is critical because it
relays the harmonics and ambience in audio, and the depth and clarity in video.
Furman's exclusive Linear Filtering Technology dramatically reduces noise,
ensuring consistent peak operation regardless of load conditions or the time of
day.
Series Multi-Stage Protection (SMP): SMP is maintenance-free
surge suppression, offering AC protection without sacrificing itself in the event
of a catastrophic surge. The SMP circuit senses voltages so high that operation is
impossible and turns the power off before damage can occur; if the voltage exceeds
140 volts power is removed from all the outlets and the
Extreme Voltage LED lights.
EVS: The Extreme Voltage Shutdown (EVS) circuitry constantly
monitors the line voltage for unsafe over-voltage conditions. When an extreme
voltage is recognized all 12 outlets are automatically disconnected to protect
your equipment. Once the line voltage returns to normal the outlets are
reconnected.
12 AC Outlets: The Furman SPR-20i features 12 rear-panel outlets
in three sections; all the outlets are 3-prong NEMA 5-20R T-Slot receptacles and will
accept either standard NEMA 5-15 or NEMA 5-20P plugs:
- Video Bank: The video bank has four
outlets. In addition to the linear filter, an ultrasonic
filter specifically benefits video components (DVR, DVD
player, projector, Plasma and LCD TVs, etc).
- Audio/Video Bank: The audio/video bank
has four outlets, EMI and RFI noise is removed by the linear
filter.
- Audio Bank: The audio bank has four
outlets, EMI and RFI noise is removed by the linear filter.
Transient Voltage Surge Protection: The SPR-20i features transient
voltage surge suppression for standard telephone lines, coaxial cable TV lines, and
coaxial satellite lines. There is one pair of phone input/output jacks and three pair
of coaxial input/output jacks. The coax jacks are bi-directional and pass both DC
carrier signals and high bandwidth HD signals with an insertion loss of less than
0.1 dB. All the in-line surge suppressors feature Furman's exclusive Zero Ground
Contamination technology; this aids in eliminating audio buzzing and the video hum
bars that can result from typical in-line suppressors.
Rack Mount: Brackets are included to rack mount the SPR-20i.
Controls and Indicators
Front Panel:
- Power: power switch; turns all outlets
on/off
- Display: the blue LED display illuminates
when the power switch is on; you can switch between showing the
line input voltage and the input current
- Protection OK LED: illuminates to indicate
that the wall outlet is properly grounded and Line/Neutral
polarity is correct
- Extreme Voltage LED: illuminates to
indicate the incoming voltage is too high and all the
outlets have been disconnected
- Display Switch: toggle the display
between showing the line input voltage and the input
current

Warranty
Connected Equipment: Furman Sound's Connected Equipment
Warranty covers equipment that is damaged by a transient voltage while properly
connected through the Furman SPR-20i to a properly wired AC power line
with a protective ground in an indoor location. Furman's Connected Equipment
Warranty is limited to the amount of the deductible on the Purchaser's personal
property insurance policy, up to $500.00. The Connected Equipment Warranty is in
effect for a period of five years.
