Analog inputs 

The Omicron Monaural Power Amplifier has both balanced (XLR) 

and single-ended (RCA) inputs. Both types of inputs have been 

carefully optimized to give the best possible performance. However, 

the most realistic and natural sonic quality is obtained by using the 
balanced inputs on your amplifier. 

The balanced (XLR) and single-ended (RCA) inputs must be used 

separately. Ensure that your new Omicron Monaural Power Amplifier 
is OFF before changing any connections. When the amplifier is 

shipped from Classé there is a jumper between pins 1 and 3 of the 

balanced (XLR) inputs. To use your amplifier in single-ended mode 
simply connect the single-ended interconnects from the preamplifier 

to the RCA inputs of your Omicron Monaural Power Amplifier. To 

use your amplifier in balanced mode, remove the single-ended 
interconnects if attached. Remove the jumper between pins 1 and 3 

of the balanced (XLR) input and save them for later use. Connect the 

balanced interconnects from the preamplifier to the XLR inputs of 
your Omicron Monaural Power Amplifier.  

The XLR connector on your Omicron Monaural Power Amplifier is 

configured as follows: 

PIN 1: Ground    

 

 

 

 

        

PIN 2: Positive (Non-inverted) Signal, “hot”  

 

         

PIN 3: Negative (Inverted) Signal 

All Classé products share the same balanced (XLR) pin out. Other 

manufactures may use a different balanced (XLR) pin out 

configuration. Please contact the manufacturer if you wish to 

maintain consistent phasing throughout your system when connecting 
Classé products with equipment from other manufacturers.
