IT-REFERENCE 16 E OWNER’S MANUAL
system with high current demands.
The total continuous current draw of most
electronic components is typically listed in
watts by their AC input cord or AC connector.
Watt ratings are simply added to determine the
total system RMS current draw. It should also
be noted that the IT- Reference 16 E’s power
correction circuitry has no actual effect on the
power drawn from your utilities’ power meter.
The IT-Reference 16 E draws a mere 2 watts
independent of other components, so it may be
left on at all times.
Soft Start - Continuous Use and
Break-In Time:
When power is rst applied to the IT-Reference
16 E, (the front panel breaker- power toggle
must be switched to the “on” position) the Soft
Start feature is activated. There is an audible
“clack” when the IT-Reference is rst turned on
or off. This sound is produced by the Soft Start
circuit’s 30 Amp relay engaging or disengaging.
There is nothing in the IT-Reference 16 E’s
construction, design, or componentry to wear
over the lifetime of the product, and there
is no power draw from your electric service
meter aside from the LED power indicator,
relay, and GFCI protection circuit. For this
reason the IT-Reference 16 E may be left
with its power engaged permanently. This is
an added benet, as many audio/videophiles
nd performance improves signicantly when
leaving low-powered components permanently
charged (turned on). In fact, this is true of the
IT- Reference 16 E. Though it will function
awlessly right from its shipping carton, the
performance of its circuit parts will improve
after approximately two weeks of continuous
use or “break-in.”
Ground Fault Interrupter (GFCI):
The IT- Reference 16 E’s “Discrete
Symmetrical Filtered AC outlets” incorporate
a balanced AC power output, whereby both
the neutral and positive leads of the AC cable
run at 115 Volts AC in opposing polarity,
referenced to ground (0 Volts AC). This is but
one of the IT- Reference 16 E’s advantages
over other AC-lter/protection designs.
Though virtually all electronic equipment is
designed to detect electrical shorts and other
potentially dangerous equipment problems in
the line lead referenced to its Neutral, this is
inadequate when power is “balanced.” With
the IT-Reference 16 E, both neutral and
positive legs contain 115 VAC relative to their
Ground tab. This is not a problem or safety
hazard, unless there is a defect in either
the IT- Reference 16 E’s transformer, or the
power supply of a connected component. In
this instance, we need to assure that safety is
always maintained. The solution is our GFCI
(ground fault circuit interrupter).
The Furman GFCI detects any imbalance in
the current owing in the two hot legs. The
missing current is presumed to be owing
through the ground conductor (the round
pin on an AC outlet). Ground current often
indicates a dangerous partial or full short
circuit. If an imbalance is detected, the GFCI
will trip the main circuit breaker/power switch.
To restore operation, correct the fault and turn
the unit on again. 5 mA of current is enough
to cause the GFCI to trip; to troubleshoot this
type of problem, start with nothing connected
to the IT-Reference 16 E. Then, add each
piece of equipment until the GFCI trips.
Contact the manufacturer of the suspect unit
for possible solutions.
