shutter that covers the optical digital audio
output and connect the cable firmly so that the
configurations of both the cable and the
connector match.

For your reference:
Dolby Digital (AC-3) is a digital sound
compression technique developed by the
Dolby Laboratories Licensing Corporation,
supporting 5.1-channel surround sound, as
well as stereo (2-channel) sound, this
technique enables a large quantity of sound
data to be efficiently recorded on a disc.
Linear PCM is a signal recording format used
in CDs. While CDs are recorded in
44.1kHz/16 bit, DVDs are recorded in
48kHz/16 bit up to 96kHz /24 bit.
If you have a Dolby Pro Logic Surround
decoder connected to the DVD’s analog
AUDIO OUT connectors, thanks to the
”Downmix” function of the DVD you will
obtain the full benefit of Pro Logic from the
same DVD movies that provide full 5.1-chan-
nel Dolby Digital soundtracks, as well as from
titles encoded with Dolby Surround.
The DVD is designed to digitally output
96kHz-PCM audio with a 96kHz sampling
rate. However, some 96kHz DVD's may
include copy protection codes that do not
permit digital output. For full 96kHz fidelity
from these discs, use the analog outputs of
the DVD.
IMPORTANT:
If your surround processor/D/A
converter does not support 96kHz PCM audio,
you must use the DVD analog outputs for full
96kHz fidelity with these discs.
Caution for the optical/coaxial
digital audio outputs:
When connecting an amplifier (with an
optical/coaxial digital input ) which does not
contain a Dolby Digital (AC-3) or DTS
decoder, be sure to select ”PCM” as initial
setting in the ”Digital Output” menu (see
also page 19).
Otherwise, any attempt to play a DVD may
cause such a high level of noise that it may
be harmful to your ears and damage your
speakers.
CD’s can be played as they would normally
be played.
Note:
Some first generation DTS decoders which do
not support DVD-DTS interface may not work
properly with the DMC 250 player.
Dolby Digital, DTS and PCM signals are
passed through the
HDMI Output
A
.
You can either use this HDMI connection or
connect the
6-Channel Audio Outputs
B
to the corresponding input jacks on your
receiver or processor in order to enjoy DVD-
Audio materials.
Notes when connecting the
optical digital audio cable
(optional)
Gently push the cable plug through the
built-in shutter that covers the optical digital
audio output and connect the cable firmly so
that the configurations of both the cable and
the connector match.
Dolby Digital and DTS
Both Dolby Digital and DTS are audio formats
used to record 5.1-channel audio signals onto
the digital track of film. Both of these formats
provide six separate channels: left, right, center,
left rear, right rear, and common subwoofer.
The latest 6.1-formats, Dolby Digital EX and
DTS ES, even one (or two) additional "Surround
Back" channel for a center between the rears.
Remember, that Dolby Digital or DTS will only
play 5.1-channel sound if you’ve connected the
optical or coaxial output of the DMC 250 player
to a DTS or Dolby Digital receiver or decoder and
if the disc was recorded in the Dolby Digital or
DTS format.
