2 faint scratches on the top silver panel near the rear 3. One scratch on the left side rear. Various scratches on the rear panel from inserting cables. Some glue residue around 2 screws on the right side rear. This is from the factory.I have cleaned the whole unit with a diluted mild cleaner and a micro fiber towel. I used compressed air in the vents and all rear connections. These were used for a few months on the unit. Pangea 20 Amp AC to 15A IEC Adapter.
Product Description: An Ultra-Stable 120 VAC Power Supply. Your 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. 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. "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 Noise. In 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. Another 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. 12-outlet power conditioner ideal for video systems.
