Classé Omega SACD Player: Design Overview
The Classé Omega SACD is the result of many
years of digital-audio design expertise. It is an
exciting development, the first high-end audio
implementation of Sony’s new digital audio format.
Use only the correct size fuse:
— 100-110 Volts
1.25 Amp, 3AG Slo-Blo
— 220-240 Volts
Transport
0.5 Amp, 5 mm x 20 mm Slo-Blo
The transport mechanism in the Omega SACD
Player is Sony’s new reference-level SCD-1 Super
Audio CD mechanism. This mechanism uses
Sony’s now familiar method of holding the laser
optics stationary while moving the spinning disc
as the data is retrieved. The stationary laser
assembly provides reduced error and jitter, and
greater stability while reading the disc.
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.
In addition, this advanced mechanism uses
two laser assemblies, a long wavelength (780
nanometers) laser for CD playback, and a short
wavelength laser (680 nanometers) for Super
Audio playback.
Digital Filtering Section
The digital filter is a flexible and elegant design
that provides the optimum filter for all of the digital
audio formats the Omega SACD can process. The
Omega SACD automatically selects the optimum
filter for standard CD, HDCD and SACD. In
addition, the user can select a 96 kHz sample-rate
converter filter when processing PCM data.

DAC Section
UNPACKING AND POSITIONING
CONNECTIONS
The digital to analog conversion circuitry is a
completely new design by Classé Audio. This unique
design utilizes six channels of the Crystal CS4397
delta-sigma converter. For each of the Omega
SACD balanced outputs, two channels of this DAC
are used, one for the positive signal and one for
the negative. For the single-ended outputs, the
remaining two channels are used, one for the
right and one for the left. This unique arrangement
allows for full balanced operation and
Unpack your Omega SACD Player 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.
Pictured here is the rear of the Omega SACD
main unit showing all input and output
connections. Refer to the page number indicated
for more information on these connections.
Connecting the Power Supply to the Main Unit
Before connecting the AC mains, you must connect
the power supply to the main unit. Using the
umbilical cord included in the carton, connect the
power supply to the main unit. Align the
connectors on either end of the umbilical and firmly
press them into the sockets labeled DC SUPPLY on
the power supply and main unit. Rotate the collar
on the umbilical connectors to secure the
connection.
Contents
Included in the carton should be the following
items:
uncompromised single-ended operation as well.
In addition, it means that the balanced and single-
ended outputs produce the same output level.
1. Main unit
2. Power supply unit
3. Power supply umbilical cord
4. AC mains cord
5. Remote control and 2 AAA batteries
6. Disc stabilizer
Power Supply
Classé engineers have long recognized the
importance of pure power for high-performance
digital designs. The Classé Omega SACD player has
the most sophisticated power supply of any Classé
digital product. The Classé Omega SACD Player
uses a massive regulated outboard power supply.
This chassis houses two transformers, one for
digital circuitry, and one for analog, as well as
active pre-regulation. This arrangement assures
that the audio circuitry is provided with a power
source completely free of digital noise. In addition,
the power supplies for each section of circuitry
are double- or triple-regulated within the main
chassis. Again, this ensures not only complete
rejection of AC line noise, but prevents noise from
being transmitted between sections within the
main chassis.
7. Warranty card
8. This manual
Never disconnect the umbilical cord without first
disconnecting the AC mains from the wall outlet.
If any of these items is missing, contact your
dealer immediately.
Installing batteries in the remote control
To install the batteries in the remote control,
remove the screws that hold the battery cover to
the back of the remote. Install the two AAA
batteries as indicated on the plastic battery holder
inside and replace the cover.
Positioning the Omega SACD Player and
Power Supply
For best performance, place your Omega SACD
Player on a solid, non-resonant surface. Do not
place the Omega SACD Player directly on top of
another component.
Place the Omega SACD Power Supply close enough
to the main unit so that the umbilical cord can be
connected to both units. Do not place the power
supply in direct contact with the main unit.

AC power
Selecting Analog outputs
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 power supply 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.
The Omega SACD Player has both balanced (XLR)
and single-ended (RCA) outputs. Both types of
outputs 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 a balanced input on your
preamplifier.
The balanced output is derived from a balanced
digital signal, which is converted to analog using
two DACs per channel followed by differential
output circuitry. The unbalanced output is converted
by a separate DAC followed by dedicated single-
ended circuitry.
Connect the AC power cord to the rear of the
power supply unit and directly to an AC outlet.
For best results, do not use extension cords or
multiple-outlet “power strips”. Also, do not
disable the ground pin as this can increase the
risk of electric shock.
Both the balanced and single-ended outputs can
be used simultaneously, and both have the same
output voltage.
Digital inputs
The Omega SACD Player is equipped with two
digital inputs, which accept any standard PCM
digital audio format from 32 kHz to 96 kHz
sampling rate. One input uses an SPDIF (RCA)
connector and the other uses TOSLINK.
Infrared (IR) input and output
The Omega SACD Player 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 SACD Player
is outside of the line-of-sight of your listening
location. Contact your Classé dealer for information
on installing and using remote IR repeating
equipment.
Digital outputs
The Omega SACD Player is equipped with three
digital outputs: one AES/EBU (XLR connector),
one SPDIF (RCA connector) and glass optical fiber
(ST connector). These can be connected to a digital
recorder or other digital audio component.
The sampling rate of the digital outputs depends
on the source being fed to the output and on the
digital filter used. When using the internal transport
to play a standard CD, the digital output will be
44.1 kHz if the standard filter is selected, and 96
kHz if the sample-rate converter is selected.
When a digital input is selected, the digital outputs
will either pass the signal through at the same
sample rate if the standard filter is selected, or
produce a 96 kHz signal if the 96 kHz sample-rate
converter is selected.
The digital outputs are disabled when using the
internal transport to play a Super Audio CD.

This section describes all of the controls, front panel
display, and operation of the Omega SACD Player.
PLAY
Turning on AC power
Pressing the PLAY key will begin playing.
If the drawer is open, PLAY will cause the drawer
to close.
The Omega SACD is turned on by means of a
power switch located on the power supply unit.
Do not turn the AC power on until all connections
have been made.
SKIP FORWARD/SKIP BACK
Use these keys to select a track on a disc. You can
select a track while the Omega SACD is reading a
disc and searching for the Table of Contents.
Standby mode
If the Omega SACD Player is left idle for more than
five minutes, it will automatically enter Standby
mode. In this mode, the front panel display and
transport power supplies are turned off, saving
power. However, the low-level analog power
supplies remain on for maximum sonic performance
When the Omega SACD Player is in Standby mode,
a single LED indicator on the main-unit front panel
will illuminate. In addition, the power indicator on
the power supply will remain illuminated.
The Omega SACD Player will automatically return
to regular operation when any key on the front
panel or remote control is pressed.
OPEN/CLOSE
This key opens and closes the disc-loading door.
Pressing PLAY will also cause the door to close.
Note that the loading door will close automatically
if left open for over one minute.
SACD/CD
This key allows the user to select which layer of
a multi-layer hybrid SACD disc is played. Pressing
this key toggles back and forth between SACD and
CD playback. The switch setting is indicated by
the LEDs above the key on the top panel, and also
on the front panel display. Note that the SACD/CD
key only works when the unit is not playing.
When using a single layer disc – either SACD
or standard CD – the Omega SACD player
automatically selects the appropriate layer and
the SACD/CD key is disabled. In addition, the
Omega SACD automatically defaults to the
SACD layer when playing a dual-layer hybrid
SACD/CD disc. Thus, the only time the SACD/CD
key is used is to select the CD layer on a dual-layer
SACD/CD recording.

Using the direct access keypad
SRC (Sample-Rate Converter)
The ten-digit keypad on the remote control can be
used to directly access any track on the disc. Press
the digits of the track you wish to access.
The Sample-rate converter will convert PCM (Pulse
Code Modulated) signals from the digital inputs or
from a CD playing on the internal transport, to 96
kHz sample rate. The signal is then processed by a
4-times over-sampling filter before it is fed to the
internal DAC section. In addition, the 96 kHz signal
is routed to all digital outputs.
To access a track number greater than 11, press the
>10 key, and then enter the two digit track number.
Selecting inputs
Press the INPUT key on the remote control to select
between either of the digital inputs and the internal
transport. As shown in the illustration below, each
time the INPUT key on the remote control is pressed
the Omega SACD advances to the next input. The
front panel display shows the selected input by
illuminating INTERNAL, SPDIF, or TOSLINK indicators
on the front panel display.
Note that if the Sample-rate converter is selected,
the HDCD decoding filter will be disabled – even
if the signal being processed was recorded using
HDCD. Also, the Sample-rate converter works only
on PCM (Pulse Code Modulated) signals and will
therefore not operate when playing Super Audio
CDs on the internal transport. Lastly, note that the
Sample-rate converter will disable the de-emphasis
flag from the signal at the digital output. If an
emphasized signal is connected to an outboard
converter while using the Sample-rate converter,
the outboard unit will not recognize the emphasis
flag and will not engage de-emphasis filters. The
result will be slightly elevated high-frequency
response.
When any external input is selected, the internal
SACD/CD mechanism will automatically power off
after approximately 60 seconds, saving power and
improving sound quality.
To select the 96 kHz Sample-rate converter, press
the SRC key on the remote control. To return to the
Standard filter, press the SRC key again. When the
Sample-rate converter is engaged, the display will
illuminate “SRC”.
