note 1

Average power with music as program source. The amplifier driven to clip level.

note 2

Normal music power with 9dB headroom, IEC standard power rating.

HEAT POWER

 
The efficiency can also be calculated, it being the output-power divided by the input-power:  
267 watts / 720 watts= 37 %.

XLR Input connectors are active balanced and wired according to the IEC 268, that is pin 2 hot, and wired 
in the following way: 
 
PIN 1   

GROUND/SHIELD 

PIN 2   

HOT (+) 

PIN 3   

COLD (-) 

 

 

 

 
Within the Neutrik® Combojack there is a ¼”(6.3mm) phone jack, which is wired in parallel with the 
XLR.

The input impedance is high enough (20 kohms 
balanced) to allow ”daisy-chaining”, or multiple 
parallel input connections. The headroom of the 
input circuits is also high enough to accept the 
maximum output level from virtually any low-level 
signal source. Balanced signals are less sensitive to 
AC hum and radio interference. The source 
impedance should be less than 1 kohms to avoid 
high frequency loss in long cables.
