Digital audio output connector (Optical)
S
H
The digital audio output connector (optical) converts
electrical signals into optical signals and transfers
87
them to the amplifier. Consequently, it has a number
of features including its immunity from electrical inter-
ference from external sources and its ability to prevent
the generation of noise and its minimal effect on the
external environment.
Dolby Digital
This fully discrete format divides the music signals
into 5.1 channels: Front Left (L), Front Right (R),
Center (C), Left Surround (LS), Right Surround (RS)
and Subwoofer (SW: 0.1 channel) for recording and
playback. The number of channels that are recorded
depends on the software. (1 to 5.1 channels)

Dolby Pro Logic
This format records signals from four channels [Front

Surround (S)] in two channels, decodes those chan-
nels through a Dolby Pro Logic decoder, and then out-
puts the resulting signals in four channels.
dts

(L), Front Right (R), Center (C), Left Surround (LS),
Right Surround (RS) and Subwoofer (SW: 0.1 chan-

Letterbox screen
This refers to a screen on which the playback picture
of wide-screen DVDs or Video CDs appears with black
bands running along the top and bottom.
LPCM (Linear PCM audio)
In this format, the audio signal is converted to digital
data and recorded in two channels without compres-
sion. Because the capacity of a DVD video disc is
large, it can store more data with better accuracy than
a CD.
Pan & Scan screen
This refers to a screen on which the playback picture
of wide-screen DVDs or Video CDs is cut off at the left
and right sides.
Playback control (Video CD)
If the Video CD has "With Playback Control" or others
written on the disc surface or on the jacket, the scenes
or information to be viewed (or listened to) can be
selected interactively with the screen by looking at the
menu shown on the screen.
In these instructions, playback using the menu screen
is referred to as the "menu play" for video CDs. This
player supports Video CDs with playback control.

some small sections (chapters). Each section is num-
bered; these numbers are called "Title number" or
"Chapter number".
