Audio output from the unit’s optical/
coaxial digital audio output connector
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.

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-channel 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.
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 DVD/CD player.
Dolby Digital, DTs and PCM signals are passed ■
through the
HDMI Output
A but are not
processed in the AVR Receiver in your system.
Connect the Digital Audio separately besides
HDMI to get sound from your system Receiver.
DVD-Audio signals are not carried via the HDMI
connection or the Coaxial or optical Digital Audio
outputs. you must connect the
6-Channel Audio
Outputs
B
to the corresponding input jacks on
your receiver or processor in order to enjoy DVD-
Audio materials.
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 DVD player to a DTs or Dolby
Digital receiver or decoder and if the disc was recorded
in the Dolby Digital or DTs format.
DVD-Audio
The high-resolution output of DVD-Audio discs is only
available as an analog signal. for that reason, it is
necessary to make direct analog connections between
the
6-Channel Audio Outputs B on the DVD and
the matching 6-channel inputs on your receiver or
surround processor.
