Digital audio connections

Connecting to a decoder with Dolby Digital
processing or MPEG processing
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.

*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.
For your reference :
Dolby Digital 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 44.1 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.
