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

Connections

Rear Panel:

• Video Outlets: four linear filtered and ultrasonic filtered outlets
• Audio/Video Outlets: four linear filtered outlets
• Audio Outlets: four linear filtered outlets
• Phone Jacks: input and output for standard telephone line
• Coaxial Jacks: 3 pair of threaded F-type coax input and output terminals

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.
