The Elite-20 PF i also features remote control capability via 12V triggering, compatible with the 12V triggering devices commonly found in power receivers and pre-amp processors. Additional products (such as a remote subwoofer) can be daisy-chained from the 12V output jack for an additional triggered unit. The 12V triggering feature may be bypassed if desired. The essence of the Elite-20 PF i is Furman's unique Power Factor Technology. For the first time, low-level analog, digital, and video components are not modulated or distorted by the power amplifier's extreme AC current demands. Further, the power amplifier is fed a highly filtered, extremely low-impedance supply of AC power. The Elite-20 PF i, in fact, has in excess of 4 Amps of continuous current reserve (over 55 amps peak charge) for the most extreme peak power demands. This technology enables power amplifiers and powered subwoofers to operate at maximum efficiency, reaching levels of performance previously unattainable. When employing the Elite-20 PF i, you will immediately 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. Sonic transients will be startlingly fast with bass fundamentals that shake foundations with their weight and visceral impact. Mid and high frequencies will bloom with sweet, non-glaring ease as imaging improves dramatically, all the while remaining true to your system's inherent virtues.
