Operation; Disc Type Selection; Digital Output; Balanced Output - Sony SCD-1 Technical Background

4. Operation.

4.1. Disc Type Selection.

The SCD-1 and SCD-777ES automatically
recognize CDs and SACDs and commence
playback. By selecting the disc type in advance,
users can bypass the recognition step and go
directly to playback. Manual selection is also
useful for hybrid SACDs, which contain both
high-density and standard CD layers.

4.2. Digital Output.

Two types of digital output are available for CD
playback: coaxial and optical. To minimize radia-
tion interference, these outputs can be switched
off by a front panel control. There is no digital
output during SACD playback.

4.3. Balanced Output.

To assure the highest signal integrity at the pre-
amplifier input, the SCD-1 features balanced
analog outputs. As featured in professional audio
equipment, the balanced outputs use 3-pin XLR
connectors with separate conductors for plus,
minus and ground.

4.4. Text.

Just as Compact Disc offers a CD TEXT™
option, Super Audio Compact Disc has a
reserved area for text. The SCD-1 and
SCD-777ES can display information such as
disc title, artist name and track title for
compatible CDs and SACDs.

4.5. Display.

The SCD-1 and SCD-777ES have segmented
displays for track number and time. Because
Super Audio Compact Disc titles can have as
many as 255 tracks, the players each have a
three-digit track number display. A 15-character
dot matrix display shows text information, player
settings and user warning indications. The
Display Mode switch enables users to turn off
specific sections or the entire display.
The display window is made of thick acrylic
with beveled edges and a half-mirror coating on
the inside. This helps give the players a
distinctive look.

4.6. Remote Control.

Even the Remote Commander
It features a 1-mm aluminum top plate and but-
tons that depress with a definitive click. The
remote duplicates the front panel features and
adds track programming, shuffle and repeat
(1, all, A-B) as well as 10-key Direct Access™
track selection. Additional controls include
cue/review, index search, disc type selection
and filter switching.
The remote unit's infrared codes correspond to
Sony CD player codes. So most SACD player
functions can be operated from the CD player
mode of Sony preamplifier and receiver remote
controls. To prevent mistaken operation in sys-
tems that already include a Sony CD player, the
SACD player and remote can be switched to
"CD2" mode, engaging a separate set of remote
control codes.
® unit is distinctive.
