Note
• Some dts decoders which do not support DVD-dts interface
may not work properly with the DVD/Video CD/CD player.
For your reference:
• Dolby Digital is a digital sound compression technique
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 theatres 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 movies 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 electrical
signals into optical signals and transfers them to an amplifier.
These optical signals are immune from electrical interference,
and they also have minimal effect on other equipment.
Caution for the optional/coaxial digital audio
output connector:
• Do not connect to the digital audio input of an amplifier
that does not have Dolby Digital/dts/MPEG audio
decoder.
• If such an amplifier should be connected to the player
with “Bitstream” selected at the “2 Dolby digital”, “3 DTS
Digital Surround” (see page 61), 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 they would normally
be played.

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.
