Digital audio connections
Connecting to a decoder with Dolby Digital processing or MPEG processing A
When DVDs recorded in Dolby Digital or MPEG audio are played, Dolby Digital bitstream or MPEG audio bitstream is sent to the player's OPTICAL digital audio output connector or COAXIAL digital audio output connector. When the player is connected to a Dolby Digital or MPEG audio decoder via one of these output sockets, you can enjoy theater quality audio in you home. An optical digital cable or coaxial audio cable(both optional) is required when a Dolby Digital decoder or MPEG audio decoder is used.
Audio output from the optical/coaxial digital audio output connectors:
Disc | Sound recording | Optical/coaxial digital audio output | |
format | from connector | ||
| |||
| Dolby Digital | Dolby Digital | |
| or PCM(2ch)(48kHz/16bit) | ||
|
| ||
DVD | Linear PCM (48/96 | Linear PCM(2ch) | |
kHz 16/20/24 bit) | (48/kHz sampling/16 bit only)*2 | ||
|
| or no output*1 | |
| MPEG 1 MPEG2 | MPEG2 audio bitstream or | |
| PCM(2ch)(16 bit)*1 | ||
VCD | MPEG1 | ||
PCM (44.1kHz sampling) | |||
CD | Linear PMC | Linear PCM (44.1kHz sampling) |
*1.The type of audio output from the connector can be selected by the initial settings.
*2.Audio having 96kHz sampling is converted into 48kHz sampling when it is output from the players optical/coaxial digital audio output connector.

Linear PCM is a signal recording format used in CDs. While Cds are
recorded in 44.1 kHz/16 bit, DVDs are recorded in 48kHz/16 bit up to 96kHz/24 bit . 
If you have a Dolby Pro Logic Surround decoder, you will obtain the full benefit of Pro Logic from the same DVD movies that provide full 5.1channel Dolby Digital soundtracks, as well as from titles with the Dolby Surround mark.
Caution for the optical/coaxial digital audio output connector:
Do not connect an amplifier (with an optical/coaxial digital input connector) which does not contain the Dolby Digital or MPEG audio decoder.
An attempt to play DVDs through an amplifier without the correct or MPEG decoder, may produce extreme levels of noise. This could damage both your ears & your loudspeakers.
VCD and Audio CDs can be played as normal.
