DIGITAL AUDIO CONNECTIONS

Digital Audio Connections

Notes when connecting the opti-
cal digital audio cable (optional)

■

Remove the dust protection cap from the
optical digital audio output and connect the
cable firmly so that the configurations of both
the cable and the connector match.

■

Keep the dust protection cap and always
reattach the cap when not using the connec-
tor.

Audio output from the unit’s
optical/coaxial digital audio out-
put connector

* Digital Format must be selected as “ORIGI-

NAL“ or ”PCM” in Audio Set-Up Menu
(see page 18).

For your reference:

■

Dolby Digital (AC-3) is a digital sound com-
pression technique developed by the Dolby
Laboratories Licensing Corporation,
supporting 5.1-channel surround sound, as
well as stereo (2-channel) sound, this tech-
nique 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
44.1 kHz/16 bit, DVDs are recorded in
48 kHz/16 bit up to 96 kHz /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 25/101

is designed to digitally output

96kHz-PCM audio with a 96 kHz sampling
rate. The 96 kHz indicator will light in the dis-
play. However, some 96 kHz DVD's may
include copy protection codes that do not
permit digital output. For full 96 kHz fidelity
from these discs, use the analog outputs of
the

DVD 25/101

IMPORTANT:

If your surround processor/D/A

converter does not support 96 kHz PCM audio,
you must use the

DVD

analog outputs for full

96 kHz fidelity with these discs.

Caution for the optical/coaxial
digital audio outputs:

■

When connecting an amplifier (with an opti-

cal/coaxial digital input ) which does not con-
tain a Dolby Digital (AC-3) or DTS decoder, be
sure to select ”PCM” as initial setting in the
”Digital Format” menu (see also page 18).
Otherwise, any attempt to play 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 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.

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 25/101

to a DTS

or Dolby Digital receiver or decoder (see page
11) and if the disc was recorded in the Dolby
Digital or DTS format.
