The Furman SPR-20i Stable Power AC Voltage Regulator - Cool Running, Noise Free Technology for Optimum Listening Environments

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. Furman's 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. 

Includes Linear Filtering Technology (LiFT)

Use Your Entertainment Equipment Up to Its Full Potential

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. 

Virtually Eliminate RF and EMI Noise

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. 

Series Multi-Stage Protection (SMP) featuring Extreme Voltage Shutdown (EVS)

Superior Surge Protection

Another critical feature is Furman's 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, the 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 — without peer.
