14 DIGITAL AUDIO CONNECTIONS

Digital Audio Connections

* Digital Format must be selected as “ORIGI-

NAL“ or ”PCM” in Digital Output 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 21’s analog

AUDIO OUT connectors, thanks to the

”Downmix” function of the DVD 21 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 21 is designed to digitally output

96 kHz-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 21.

IMPORTANT: If your surround processor/D/A

converter does not support 96 kHz PCM audio,

you must use the DVD 21 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 Output” 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.

Notes when connecting the

optical 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.

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,

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 (see

page 11) and if the disc was recorded in the

Dolby Digital or DTS format.
