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 is designed to digitally output

96 kHz-PCM audio with a 96 kHz sampling rate. 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.

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 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 18).

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.

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. 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.
