Laboratories Licensing Corporation,
supporting 5.1-channel surround sound, as

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 and SACD signals are
not carried via the HDMI connection. You
must connect the 6-Channel Audio
Outputs to the corresponding input
jacks on your receiver or processor in order to
enjoy DVD-Audio and SACD 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 and SACD
The high-resolution output of DVD-Audio and
SACD 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 47 and the
matching 6-channel inputs on your receiver or
surround processor.
