severely damaged or destroyed.

Do not operate the Classé Omega SACD Player
with any portion of the chassis removed or open.
Dangerous voltages and laser radiation 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 SACD Player power supply unit.

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

1.25 Amp, 3AG Slo-Blo

— 220-240 Volts

0.5 Amp, 5 mm x 20 mm Slo-Blo

Do not open this unit. There are no user-serviceable
parts inside. Please refer service to an authorised
service technician.

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
SACD Player.

How to use this manual

The symbol to the right of the page indicates a
section of the manual that is of particular
importance for safety or to prevent damage to
your Omega SACD Player.

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 SACD Player. However, if you want to begin
listening to your Omega SACD Player immediately,
skip to the section titled Controls and Operation.

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.

Transport

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.

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

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
uncompromised single-ended operation as well.
In addition, it means that the balanced and single­ended outputs produce the same output level.

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.

UNPACKING AND POSITIONING

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.

Contents

Included in the carton should be the following
items:

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

7. Warranty card

8. This manual

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.

CONNECTIONS

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.

Never disconnect the umbilical cord without first
disconnecting the AC mains from the wall outlet.
