IT-REFERENCE 15 OWNER’S MANUAL

sub-woofers should be connected to these four 

outlets.

Many Audiophile and premium Home Theater 

systems will have combined continuous 

current demands below 15 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 15 was designed to more 

than meet this demand.  Additionally, our 

Power Correction Circuitry effectively creates 

a current reserve in excess of 55 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 15 was designed for steady 15 

Amp operation, and peak current demands 

many times that, the maximum total continuous 

current draw may be limited to a range 

between 1300 - 1700 Watts per IT-Reference 

15 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 15 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 15’s power 

correction circuitry has no actual effect on the 

power drawn from your utilities’ power meter.  

The IT-Reference 15 draws a mere 8.5 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 fi rst applied to the IT-Reference 

15, (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 fi rst turned on or 

off.  This sound is produced by the Soft Start 

circuit’s 30 Amp relay engaging or disengaging.  

There is virtually nothing in the IT-Reference 

15’s construction, design, or componentry to 

wear over the life time 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 15 may
