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-20’s exclusive Stable Power AC Voltage Regulation Technology, voltage-starved power amplifiers and powered sub-woofers perform at their full potential. With the SPR-20, home theaters are supplied with constant, virtually unwavering AC voltage. This assures trouble-free service for any environment suffering from unstable power.

The SPR-20 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 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-20, 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 15 or 20, home theaters will reap the dual benefits of Furman’s Stable Power and Discrete Symmetrical AC Filtering, ensuring performance without compromise – without peer.
