Introduction
For over 32 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 16 E’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 agship power conditioner, the
IT-Reference 16 E.
Today’s AC lines are plagued with ever
increasing noise. When AC noise couples
into a 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 16 E’s exclusive Discrete
Symmetrical Power, video screens, projectors,
CD-DVD players, pre-ampliers, and scalers
are fed linearly-ltered ultra-low-noise Discrete
Symmetrical Power. This dramatically reduces
AC noise, ensuring peak operation of your
critical components. For the 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 three discrete
AC outlet banks. This positively breaks noiseinducing 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 preamplier-
processor to function free of performancedegrading digital noise from a satellite receiver.

The IT-Reference 16 E also employs our
unique Power Factor Correction Circuit. For
the rst time, low-level analog, digital, and
video components are not modulated or
distorted via the power amplier’s extreme
AC current demands. Further, the power
amplier sees a highly ltered, extremely
low-impedance supply of AC power. The ITReference 16 E, 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 ampliers and powered subwoofers to
work at peak efciency and reach levels of
performance previously unattainable.
No longer will your amplier’s performance
be at the mercy of your home’s incoming AC
power or inferior AC protection/ltering devices.
The net effect is as if your power amplier
doubled in power and improved immeasurably
in quality.
When employing the IT-Reference 16 E 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
denition, 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 while
imaging improves dramatically, all the while
remaining true to your system’s inherent
virtues.
Installation:
Unpacking
Before unpacking your unit, inspect the carton
for any obvious severe damage to the box and
internal protective materials. If internal damage
is likely, contact the carrier who delivered
the unit before proceeding with unpacking. If,
after unpacking, shipping damage is evident,
contact the carrier. Save all shipping and
packing materials. You may need them if you
should ever have to return the unit to the
factory service center.
The box should contain the IT-Reference
16 E unit, detachable AC cord, rack mount
kit, owner’s manual, and warranty registration
card. If anything is missing, please contact
Furman Customer Service. Fill out and return
your warranty registration card. Registration
is recommended because it can be used
to establish whether the unit is within the
warranty period should your original ownership
documents be lost, and it assists us in
informing you about upgrades or other vital
information.
Safety Information - Warnings
Please read and observe all of the safety and
operating instructions before the IT-Reference
16 E is operated. Retain these instructions for
future reference.
•
Do not disassemble or modify in any way.
No user-serviceable parts inside.
•
Keep away from moisture and avoid
excessive humidity
•
Do not allow liquids or foreign objects to
enter the unit
•
Household lighting equipment may not be
connected to the IT-Reference 16 E
because their sockets are not designed for
use with balanced symmetrical power and
may present a shock hazard. We
recommend that only audio, video and
computer processing equipment be

connected to the IT-Reference 16 E.
The IT-Reference 16 E should be serviced by
qualied service personnel when:
•
The power supply cord or plug has been
frayed or cut.
•
Objects have fallen or liquid has spilled into
the unit.
•
The IT-Reference 16 E has been exposed to
rain or other moisture.
•
The IT-Reference 16 E does not appear to
operate normally, or exhibits a marked
change in performance.
•
The IT-Reference 16 E has been dropped,
or the enclosure damaged.
Power Source
The power source to which the IT-Reference
16 E is connected should ideally be adequate
for use at 16 Amps. Though the system may
function with a 10 Amp panel circuit breaker,
nuisance circuit breaker tripping could result
at your service panel. If your system includes
multi-channel audio power ampliers that
require more than modest power demands,
a circuit breaker with a rating of at least 16
Amps (13 in the U.K.), is essential for optimum
performance.
Placement
The IT-Reference 16 E is manufactured with
four rubber feet for placement on any table,
cabinet, shelf, or oor capable of supporting
its 37 kg weight. These rubber feet may be
easily removed with a standard Philips screw
driver when rack mounting adjacent to other
components. Because of the IT-Reference 16
E’s internal shielding, placement or proximity
to other components is not critical, and the
IT-Reference 16 E does not produce any
appreciable heat under standard use. The
IT- Reference 16 E may also be rack mounted
in a standard 19” (48 cm) rack by attaching
the IT-Reference 16 E rack ears. These rack
ears (contained within the plastic rack kit
package) mount ush with the back portion
of the IT- Reference 16 E’s front panel. They
are attached to the chassis by removing the
(3) countersunk screws on each forward-
side of the chassis top cover. Each rack ear
is installed with pan-head Philips screws
contained within the IT-Reference 16 E rack
mounting kit. Due to the weight of the
IT-Reference 16 E (37 kg.), it is recommended
that placement be at or near the bottom of your
rack when choosing this mounting option.
Connections:
AC Cable Routing
Once the IT-Reference 16 E is placed, the
female end of the AC cord must be plugged
into the male IEC connector located on the
lower left hand side of the rear panel (when
facing the rear panel). Next, the male plug
must be connected to an appropriate socket.
This AC cord will carry substantial unbalanced
AC current, so it should be dressed away
from critical signal-carrying cables, or at the
very least, cross them at a 90 degree angle.
The same is true of the power amplier AC
cords when plugged into the IT- Reference
16 E’s “High Current - Amplier Power” AC
ltered outputs. All other components plugged
into “Discrete Symmetrical Power” outlets (A)
through (C) have symmetrical balanced AC
current and will radiate virtually no eld; as a
result of this technology, their placement is not
critical.
