Enjoying digital audio output from the
digital audio output connector
Note
Note when connecting the optical digital audio cable
•Remove the dust protection cap from the optical digital audio
output connector and connect the cable firmly so that the
configurations of both the cable and the connector match.
•Keep the dust protection cap and reattach when not using
the connector.

®^Compressed sound converted to PCM will be output.
*3The settings and connections necessary to enjoy CDs re­
corded in dts are the same as for DVDs recorded in dts.
•Some dts decoders which do not support DVD-dts interface
may not work properly with the DVDA/ideo CD/CD player.

For your reference:
•Dolby Digital (AC-3) is a digital sound compression tech­
nique developed by the Dolby Laboratories, Inc.
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.
•The digital theater systems (dts) is a 5.1-channel surround
sound system, which is widely used in movie theaters around
the world. It allows the bit rate to be increased in order to
provide good sound quality without excessively compressing
the data.
•Linear PCM is a signal recording format used in a CD. While
a CD is recorded in 44.1 kHz/16 bit, a DVD is recorded in
48 kHz/16 bit up to 96 kHz/24 bit.
•If you have a Dolby Pro Logic Surround decoder, you will
obtain the full benefit of Pro Logic from the same DVD mov­
ies that provide full 5.1 -channel Dolby Digital soundtracks, as
well as from titles with the Dolby Surround mark.
•The digital audio output connector (optical) converts electri­
cal signals into optical signals and transfers them to an am­
plifier. These optical signals are immune from electrical
interference, and they also have minimal effect on other
equipment.
Caution for the optical/coaxial digital au­
dio output connector:
•When connecting an amplifier (with an optical/co­
axial digital input connector) which does not con­
tain a Dolby Digital (AC-3) or dts decoder, be sure
to select “PCM” at the “2 Dolby Digital” and at the
“3 dts” of the initial setting “7 Digital Audio Out­
put”.
(See page 35.)
•if “Bitstream” is selected, any attempt to play DVDs (or
CDs recorded in dts) may cause such a high level of
noise that it may be harmful to your ears and damage
your speakers.
•Video CDs and CDs can be played as normal.
