For your reference:
■ Dolby Digital (AC-3) is a digital sound com-
pression 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
Optical/coaxial digital

Caution for the optical/coaxial
digital audio outputs:
■ When connecting an amplifier (with an
optical/coaxial digital input ) which does not
contain a Dolby Digital (AC-3) or DTS
decoder, be sure to select "PCM" as initial
setting in the "Digital Output" menu (see
also page 18).
Otherwise, any attempt to play a DVD may
cause such a high level of noise that it may
be harmful to your ears and damage your
speakers.
■ CD's can be played as they would normally
be played.
Note:
■ Some first generation DTS decoders which do
not support DVD-DTS interface may not work
properly with the DVD/CD player.
■ Dolby Digital, DTS and PCM signals are
passed through the HDMI Output
However, DVD-Audio signals are not carried
via the HDMI connection. You must connect
the 6-Channel Audio Outputs
corresponding input jacks on your receiver
or processor in order to enjoy DVD-Audio
materials.
Notes when connecting the
optical digital audio cable
(optional)
■ Gently push the cable plug through the
built-in shutter that covers the optical digital
audio output and connect the cable firmly so
that the configurations of both the cable and
the connector match.
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.
The latest 6.1-formats, Dolby Digital EX and
DTS ES, even one (or two) additional "Surround
Back" channel for a center between the rears.
Remember, that Dolby Digital or DTS will only
play 5.1-channel sound if you've connected the
optical or coaxial output of the DVD player to a
DTS or Dolby Digital receiver or decoder and if
the disc was recorded in the Dolby Digital or DTS
format.
DVD-Audio
The high-resolution output of DVD-Audio discs is
only available as an analog signal. For that
reason, it is necessary to make direct analog
connections between the 6-Channel Audio
Outputs on the DVD 37 and the matching
6-channel inputs on your receiver or surround
processor.
