IT-REFERENCE 20 OWNER’S MANUAL
(4) “High Current - Amplifi er 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
or less, excluding the power amplifi ers) utilize
one “Discrete” bank per component. This will
maximize performance by eliminating inter-
component AC noise contamination entirely!
For systems utilizing more componentry,
high performance will still be achieved with
careful routing of component AC cords to
the IT-Reference 20’s four “Discrete” power
banks. We recommend separating digital
processors, DVD’s, and CD players from pre-
amplifi ers, tuners, and tape machines. Further,
video monitors and scalers should ideally be
separated from audio components.
Connecting Components to the High
Current Power Amplifi er Banks
Many Audiophile and premium Home Theater
systems will have combined continuous current
demands far below 20 Amps. It is rare, in fact,
for large power amplifi ers to draw more than 4
Amps continuously.
For superior performance, it is vital that an AC
fi lter possess extraordinarily low impedance,
and have the capability to pass peak
current demands far in excess of the RMS
(continuous) current rating. The IT-Reference
20 was designed to more than meet this
demand. Additionally, our Power Correction
Circuitry effectively creates a current reserve
in excess of 80 amps peak up-charge that
is cleaner and faster than a dedicated line
from your local power station. This feature
eliminates any concern towards the current
compression that can result from typical power
conditioners, and the peak power reservoir
benefi ts any power amplifi ers performance
dramatically.
Note about Power Factor Correction and
Current Consumption
When power correction technology is
employed with even the most sophisticated
circuit breakers, it effectively adds to the
perceived current load. Though the IT-
Reference 20 was designed for steady 20
Amp operation, and peak current demands
many times that, the maximum total continuous
current draw may be limited to a range
between 1500 - 2100 Watts per IT-Reference
20 employed.
The RMS current available before the circuit
breaker trips varies due to what is referred to
as a vector load. Simply put, the type of power
supplies or electronic circuits connected to
the IT-Reference 20 will have an effect on its
circuit breakers perceived current load, and
therefore, when it will trip. Though the benefi ts
of power factor correction far outweigh the
small reduction in continuous current draw, this
must be accounted for when constructing a
large 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 20’s power
correction circuitry has no actual effect on the
power drawn from your utilities’ power meter.
The IT-Reference 20 draws a mere 8.5 Watts
independent of other components, so it may be
left on at all times.
