An Ultra-Stable 120 VAC Power SupplyYour AC wall voltage constantly fluctuates, and that's not good for connect AV gear. The Furman SPR-20i provides an ultra-stable 120 VAC supply from low or high voltage sources. Furman's SPR-20i generates virtually no heat and produces none of the mechanical noise typical in inferior AC voltage regulators. Exclusive 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. This new, enhanced version of the SPR-20 features a redesigned modern chassis plus an improved power supply. Its cool running, noise free technology allows placement in critical listening environments. "Fully Furmanized""I spent a night listening to my home system fully Furmanized and I have to say, in complete sincerity, I cannot remember the last performance upgrade I made in my system that moved the sound quality up (opened the door so much) as these 'optional' components," reports the September 2008 issue of Custom Retailer magazine. Typical AC Power is Plagued by NoiseIn addition to unstable voltage, today's AC lines are plagued by 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. Typical AC filters feature antiquated non-linear circuits. Though these multiple stage filters or power cleaners reduce some noise, they do so unevenly. In fact, they can add noise to your power line due to their filter's excessive resonant peaking. With Furman's proprietary Linear Filtering Technology (LiFT), AC noise is suppressed evenly, assuring maximum performance from your system. Series Multi-Stage ProtectionAnother critical feature is Furman's exclusive Series Multi-Stage Protection featuring Extreme Voltage Shutdown and a high current TVZ-MOV. 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. Furman's digital AC input voltage, output voltage, and current meters allow precise measurements of both the AC line and the current load. These meters are a valuable asset when monitoring systems that are connected to today's potentially poor power grids, or the meters may be dimmed when monitoring is not required. 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.
"I spent a night listening to my home system fully Furmanized and I have to say, in complete sincerity, I cannot remember the last performance upgrade I made in my system that moved the sound quality up (opened the door so much) as these 'optional' components." "Every single aspect of the sound through this system is dramatically superior to the same system without the Furman line conditioners. No matter how you like to dissect the sound to describe it, those things all got better. Bass extension and control, tonal balance and color palette, human-sounding voices, all aspects of realistic 3-D imaging, dynamics - the whole envelope is pushed much farther out. I even had my power amp plugged into Furman's Power Factor conditioner. This was always the last hurdle that no power conditioner we had auditioned could come close to jumping, but the Furman did it great." - Custom Retailer magazine, September 2008
