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 a DTS or Dolby Digital receiver or decoder and if the
disc was recorded in the Dolby Digital or DTS format.

reattach the cap when not using the connector.
Concerning the audio output from the unit’s
optical/coaxial digital audio output connector:
*1DigitalAudio Output (see page 27) selected ”Dolby Digital”or
”PCM”.
*2For copyright protection sound with 96 kHz sampling is converted into
48 kHz sampling when it is output from the unit’s optical/coaxial digi-

Notes when connecting the optical digital audio cable (optional)
• Dolby Digital (AC-3) is a digital sound compression technique devel-
oped 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 effi-
ciently 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
DVD1’s analogAUDIO OUT connectors,you will obtain the full benefit
of Pro Logic from the same DVD movies that provide full 5.1-channel
Dolby Digital soundtracks,as well as from titles with the Dolby
Surround mark.
