The Furman IT-Reference 20i Discrete Symmetrical AC Power Source is an AC power solution that offers total isolation between the filtered high-current outlets and the isolated symmetrical AC outlet banks. This effectively eliminates noise-inducing ground loops, hum bars, and power supply contamination between critical interconnected equipment, all without compromising electrical safety. Furman’s newly refined Dual-Screen Transformers provide the widest bandwidth for noise reduction. This allows the Furman IT-Ref-20i to reveal unparalleled levels of audio and video detail while ensuring that plasma screens, LCD screens, or video projectors remain free from AC contamination originating from an audio processor or power amplifiers.

Rock-solid protection for your home theater investment: The Furman IT-REF-20I is Furman’s largest and most robust power conditioner, weighing an impressive 81 pounds. It thoroughly cleans and conditions the AC power, which is the lifeblood of all audio/video components. Furman initially built its reputation by developing equipment to meet the extreme AC power demands of professional recording, film, and broadcast studios.

Isolation transformer for immaculate AC power for your most sensitive equipment: All electronic components operate best with a steady supply of clean AC power, and high-definition video equipment like Blu-ray players, flat-panel TVs, and projectors are notoriously finicky. The Furman IT-REF-20I addresses this issue with a built-in “isolation transformer” that provides noise-free regenerated power to eight of the rear-panel outlets. This puts an end to noise-inducing ground loops and power supply contamination between connected components. You will notice a significant improvement in picture quality and deeper black levels.

Power Factor Technology: Like a turbocharger for your amplifiers: Truly captivating sound requires wide-open dynamics. To cleanly reproduce instantaneous sonic peaks or “transients,” such as a car crash or a cymbal crash, an amplifier needs a lot of high-current power. During these moments, amplifiers, including those in receivers and powered subwoofers, may require more current than is available from your home’s AC line.

The solution? Plug your amplifier into one of the Furman IT-REF-20I’s high-current outlets. Furman’s unique Power Factor Technology creates a “current reservoir” capable of delivering over 80 amps of peak current. Your amplifier gets the current it needs when it needs it most.

Protection for every pathway: The Furman IT-REF-20I continually monitors incoming AC power, and if an overvoltage condition is detected, power is automatically shut off to all connected equipment. Furman’s rugged surge suppressor circuitry can withstand multiple catastrophic high-voltage spikes and continue to protect your system. Three sets of coaxial inputs and outputs protect your satellite, cable TV, and antenna connections. In addition, a pair of protected jacks prevents surges from entering through your phone line.
