IT-REFERENCE 20 OWNER’S MANUAL

Introduction

For over 30 years, Furman has pioneered the 

development of AC power products for the 

most demanding audio, video, and broadcast 

professionals.  Though the need for pristine AC 

power is nothing new, the IT-Reference 20’s 

technology and its unique implementation are 

revolutionary and without peer. 

The extreme AC demands encountered in 

the professional audio/video arena have 

required technological developments far in 

excess of typical home theater/audiophile 

power products.  In studios, live sound, 

and broadcast facilities, breakdown is 

unacceptable.  Equipment failure or poor 

performance is costly.  The same is true of 

today’s home theater.  Our solution based 

technology, extensive engineering expertise, 

and robust build quality have answered the 

challenge of today’s corrupted power lines, 

and led to the creation of our fl agship power 

conditioner, the IT-Reference 20.

Today’s AC lines are plagued with ever 

increasing noise.  When AC noise couples into 

your system’s critical components, it masks 

low level signals and cripples performance. 

This low level content is critical because it 

relays the crucial harmonics and ambience 

in audio, and depth and clarity in video.  With 

the IT-Reference 20’s exclusive Discrete 

Symmetrical Power, video screens, projectors, 

CD-DVD players, pre-amplifi ers, and scalers 

are fed linearly-fi ltered ultra-low-noise 

symmetrical power.  This dramatically reduces 

AC noise, ensuring peak operation of your 

critical components.  For the fi rst time, you will 

see and hear your theater or audio system as 

it should be – uncompromised.   

Further, our Discrete Symmetrical Power 

features total isolation between four discrete 

AC outlet banks.  This positively breaks noise-

inducing ground loops, hum bars, and power 

supply backwash between interconnected 

equipment, all without compromising electrical 

safety.  This enables a plasma screen to 

function without AC ground contamination 

from a compact disc player, or a preamplifi er-

processor to function free of performance-

degrading digital noise from a satellite receiver. 

The IT-Reference 20 also employs our unique 

Power Factor Correction Circuit. For the fi rst 

time, low-level analog, digital, and video 

components are not modulated or distorted 

via the power amplifi er’s extreme AC current 

demands.  Further, the power amplifi er sees 

a highly fi ltered, extremely low-impedance 

supply of AC power.  The IT-Reference 20, in 

fact, has in excess of 9 Amps of continuous 

current reserve (over 80 amps peak charge) 

for the most extreme peak power demands. 

This technology enables power amplifi ers and 

powered subwoofers to work at peak effi ciency 

and reach levels of performance previously 

unattainable. 

No longer will your amplifi er’s performance 

be at the mercy of your home’s incoming AC 

power or inferior AC protection/fi ltering devices.  

The net effect is as if your power amplifi er 

doubled in power and improved immeasurably 

in quality.  

When employing the IT-Reference 20 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 

defi nition, as well as noticeably improved depth 

and clarity. Sonic transients will be startlingly
