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.
