The IT-Reference is manufactured with four rubber feet for place-
ment on any table, cabinet, shelf, or floor capable of supporting its
weight. Because of the IT-Reference’s advanced internal magnetic
shielding, placement or proximity to other components is not criti-
cal, and the IT-Reference does not produce any appreciable heat.
The IT- Reference may also be rack mounted in a standard 19”
rack by attaching the optional IT-Reference rack ears. These op-
tional rack ears mount flush with the back portion of the IT-
Reference’s front panel. They are attached to the chassis by re-
moving 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 Rack Ear mounting kit.
Due to the weight of the IT-Reference (80 lbs.), it is recommended
that placement be at or near the bottom of your rack when choos-
ing this mounting option.
Once the IT-Reference is placed, its AC cord must be plugged
into an appropriate socket (see current rating recommendation
above). 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 amplifier AC cords when plugged into the IT-
Reference’s “Amplifier Power” AC filtered outputs. All other compo-
nents plugged into “Discrete Symmetrical Power” outlets (A) through
(D) have symmetrical balanced AC current and will radiate virtually
no field; as a result of this technology, their placement is not critical.
The IT-Reference’s “Symmetrical Power Outlets” should be em-
ployed for all components other than power amplifiers, powered
subwoofers, or powered loudspeakers. Each “Discrete” bank (A)
through (D) contains two parallel outputs, that are symmetrically
balanced, filtered, and totally isolated from adjacent output banks
or the “Amplifier Power” outlets. It should be noted that as each AC
bank’s outlets are in
parallel
, component power supply noise could
potentially “back-wash” between these units. For this reason it is
recommended that systems with minimal componentry (four units
Installation
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 for servicing.
The box should contain the IT-REFERENCE unit, 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.
The power source to which the IT-Reference is connected must
be adequate for use at 20 Amps. Though the system may function
with a 15 Amp panel circuit breaker, nuisance tripping and vastly inferior
protection could result. If your system includes audio power amplifiers
that require more than modest power demands, a circuit breaker with
a rating of at least 20 Amps is essential for optimum performance. If
other electrical loads are used on this same AC line, and the continuous
load from your equipment is in excess of 10 Amps, we recommend a
30 Amp circuit breaker wired with #10 gauge wire. For installations
which must comply with NEC codes, a dedicated 20 Amp circuit is
the minimum requirement. If in doubt, consult your local electrician.
When employing the IT-REFERENCE you will immediately no-
tice far clearer, stunningly focused sound and visual images from
your system. Video presentation will be crisp and colors true. Sonic
transients will be startlingly fast with bass fundamentals that shake
foundations with their weight and visceral impact. Mid and high fre-
quencies will bloom with sweet, non-glaring ease and imaging will
improve dramatically, all the while remaining true to your system’s
inherent virtues.
