The Furman Elite 15i represents a top-tier solution in AC power conditioning, designed to protect and enhance the performance of sensitive, high-end audio, video, and musical equipment. It goes far beyond simple surge protection, employing a multi-stage linear filtering technology (LFT) that actively identifies and dramatically reduces both electromagnetic interference (EMI) and radio-frequency interference (RFI) noise present on the AC line. This purification of the power supply is critical because such line-borne noise can degrade audio clarity, introduce visual artifacts on video displays, and cause digital components to malfunction or lock up. By delivering exceptionally clean and stable sine wave power, the Elite 15i ensures that connected gear operates at its full sonic and visual potential, revealing finer details and improving overall system dynamics and low-level resolution.

The unit is housed in a robust, rack-mountable chassis constructed from heavy-gauge steel, featuring a distinctive illuminated front panel with a precision voltmeter. This meter provides real-time monitoring of the incoming line voltage, allowing users to identify potential brownout or over-voltage conditions before they affect equipment. Power distribution is managed through 15 rear-panel outlets, with several often designated as "high-current" outlets to accommodate power amplifiers or other demanding devices without current limitation. Front-panel access includes two conveniently placed outlets and a main power switch with a sequencing feature. This sequential power-up and shutdown capability prevents damaging transient thumps and surges by controlling the order in which different components are energized, a vital function for complex systems.

Safety and reliability are foundational to the design. The Elite 15i incorporates a high-grade, fail-safe surge suppression network with visual status indicators to confirm protective circuitry integrity. Its linear filtering technology is non-current-limiting, meaning it does not restrict instantaneous current draw, ensuring amplifiers receive the fast, dynamic power they demand for uncompromised performance. By combining noise filtration, voltage monitoring, sequential switching, and robust surge protection into a single integrated unit, the Furman Elite 15i provides a comprehensive foundation for a professional or audiophile system. It effectively shields valuable electronics from common power anomalies while creating a pristine electrical environment that allows every component to perform with greater accuracy, stability, and longevity.
