SAFETY PRECAUTIONS
Warning: failure to comply with these safety
instructions can cause serious injury or death, or
cause your Classé Omega Monaural Power
Amplifier to be severely damaged or destroyed.
Do not operate the Classé Omega Monaural Power
Amplifier with any portion of the chassis removed
or open. Dangerous voltages may be encountered.
Connecting this unit to AC voltages other than that
specified on the rear of the unit may cause
extensive damage and increase risk of shock. Check
to make sure your local AC voltage matches the
voltage specified on the rear of your Classé Omega
Monaural Power Amplifier.
Do not operate this product near sources of heat
such as radiators, fireplaces, or heat registers.
Extreme heat may damage this unit.
To reduce the risk of electric shock or fire do not
expose this unit to water or moisture.
Use only the correct size fuse:
— 100-110 Volts
15 Amp, 3AG Slo-Blo
— 220-240 Volts
12 Amp, 3AG Slo-Blo
Do not open this unit. There are no user serviceable
parts inside. Please refer service to an authorised
service technician.
Unplug this unit when unused for long periods or
during lightning storms.
INTRODUCTION
Congratulations
Congratulations on your new purchase. From all of
us at Classé, we hope you enjoy many years of
musical satisfaction from your new Classé Omega
Monaural Power Amplifier.
How to use this manual
The symbol at left indicates a section of the manual
that is of particular importance for safety or to
prevent damage to your Omega Monaural Power
Amplifier.
Please make note of all safety precautions described
in the previous section of this manual.
It is highly recommended that you familiarize
yourself with all aspects of the operation of your
Omega Monaural Power Amplifier. However, if you
want to begin listening to your Omega Monaural
Power Amplifier immediately, skip to the section
titled Connections.
Classé Omega Monaural Power Amplifier:
Design Overview
The Classé Omega Monaural Power Amplifier is the
result of repeated listening design sessions. The
sound is fine tuned by the exchanging and mixing
of parts and the adjusting of many specific
operating voltages. The result of these sessions is a
sonic recipe that yields a natural harmonic realism
typical of instruments in a live performance.
Unique Circuit Design
The Classé Omega Monaural Power Amplifier
circuitry design is a completely new design by
Classé Audio. This unique design utilizes 64 output
devices in a special arrangement designed to
maintain internal rail voltage under the most
adverse conditions. The 64 output devices are
divided evenly, 32 being utilized to maintain rail
voltage, and the other 32 utilized as output power
devices. The result of this unique design is an
amplifier which offers uncompromised performance
even under the most adverse conditions.

UNPACKING AND POSITIONING
Unpack your Omega Monaural Power Amplifier
carefully. If you notice any shipping damage,
contact your dealer immediately. Saving the
packaging material is advised in case the unit needs
to be shipped for service. If you choose to dispose
of the packaging, please recycle.
Contents
Included in the carton should be the following
items:
1. Main unit
2. AC cord
3. Warranty card
4. This manual
If any of these items are missing, contact your
dealer immediately.
Positioning the Omega Monaural
Power Amplifier
For best performance, place your Omega Monaural
Power Amplifier on a solid, non-resonant surface.
Do not place the Omega Monaural Power Amplifier
directly on top of another component.
Place the Omega Monaural Power Amplifer near its
final set-up position, allowing 8 inches of clearance
at the rear for tightening the speaker output
connectors.
The power transformer in the Omega Monaural
Power Amplifier is located at the bottom of the
chassis and just behind the front plate. Ideally a few
feet should separate this area from any components
which are susceptible to hum. These include
preamplifers, turntables and interconnect cables.
Allow 6 inches above and on each side of the unit
to provide adequate cooling.
CONNECTIONS
AC power
Check that the AC voltage for which this unit is
configured matches your local AC line voltage. The
correct operating voltage is indicated on the rear of
the chassis, adjacent to the AC power inlet.
Operating this unit on AC voltage other than that
specified on the rear of the unit can damage or
destroy this unit and increase the risk of electric
shock.
Connect the AC power cord to the rear of the unit
and directly to an AC outlet – See Fig 1. For best
results, do not use extension cords or multipleoutlet “power strips”. Also, do not disable the
ground pin as this can increase the risk of electric
shock.
Pictured below is the wall plug of the Omega
Monaural Power Amplifier showing the live and
neutral pins. For optimum performance make sure
the pins maintain proper polarity.
Analog inputs
The Omega Monaural Power Amplifier has both
balanced (XLR) and single-ended (RCA) inputs – See
Fig 1. Both types of inputs have been carefully
optimized to give best possible performance.
However, the most realistic and natural sonic quality
is obtained by connecting the balanced outputs to
the balanced inputs on your amplifier.
The balanced (XLR) and single-ended (RCA) inputs
must be used separately. Ensure that your new
Omega 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 Omega 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 Omega
Monaural Power Amplifier.
The XLR connector on your Omega 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 manufacturers may use a different
balanced (XLR) pin out configuration. Please contact
the manufacturer if you wish to maintain absolute
phase throughout your system when connecting
Classé products with equipment from other
manufacturers.
Infrared (IR) input and output
The Omega Monaural Power Amplifier is equipped
with 1/8“ mini-plug connectors that allow the unit
to directly receive and transmit remote IR
commands. These connectors can be used with
equipment that receives IR commands and converts
them for transmission on copper wire. This is
especially useful for situations where the Omega
Monaural Power Amplifier is outside of the line-ofsight of your listening location. Contact your Classé
dealer for information on installing and using
remote IR repeating equipment.
