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.
