Furman's SPR-20i prevents unstable AC power from holding back the performance of your home theater or music system. It also guards against harmful power spikes and surges, and filters out the noise riding along on your home's electrical wiring. Never heard of Furman? Most studio engineers have. The company's spent over 30 years meeting the extreme AC power demands of professional recording, film, and broadcast studios.
An oasis of stable power for your system
As heavier and heavier demands are placed on the nation's aging power grid, inconsistencies in the quantity and quality of every home's AC power will only get worse. These fluctuations may not affect your refrigerator or dishwasher, but they can cause problems for the delicate circuitry in audio/video equipment, shortening your gear's lifespan and degrading both picture and sound quality. The SPR20i maintains an unwavering 120 volts you can check it on the front-panel display. And unlike most voltage regulators, this one is designed to work with heavy-duty 20-amp circuits.
See and hear the signal, not the noise
The SPR20i's wide-bandwidth filtering cuts way down on the AC "line noise" that can mask subtle ambient sounds and fine picture detail. Twelve AC outlets on the back panel are divided into three banks, to isolate your system's digital and video circuits from analog components and amplifiers. This helps prevent noise created by one component from affecting the power going to your other plugged-in equipment. These outlets will work with 20-amp or standard 15-amp AC plugs, and they've got hospital-grade connectors that grip your gear's plugs securely.
