Each DVD disc has a variety of audio output options.
Set the player’s Digital Audio Output according to the
type of audio system you use. 

DOLBY DIGITAL/PCM: Select “DOLBY DIGITAL/PCM”
if you connected the DVD Player’s DIGITAL OUT jack to
a Dolby Digital decoder (or an amplifier or other equip-
ment with a Dolby Digital decoder).

Stream/PCM: Select “Stream/PCM” if you connected
the DVD Player’s DIGITAL OUT jack to an amplifier or
other equipment with a DTS decoder, Dolby Digital
decoder or MPEG decoder.

PCM: Select when connected to a 2-channel digital
stereo amplifier. The DVD player outputs sounds in the
PCM 2ch format when you play a DVD video disc
recorded on the Dolby Digital, MPEG1, or MPEG2
recording system.

To change the Sample Frequency setting, first select
the desired Digital Audio Output as indicated as above.
If your receiver or amplifier is NOT capable of handling
96KHz signals, select 48KHz. When this choice is
made, this unit will automatically convert any 96KHz
signals to 48KHz so your system can decode them. 
If your receiver or amplifier is capable of handling
96KHz signals, select 96KHz. When this choice is
made, this unit will pass each type of signal through
without any further processing. 

The DRC and PBC settings can be changed.

to select the desired item and press

ENTER. The setting of the selected item is changed
between On and Off.

With the DVD format, you can hear a program’s sound-
track in the most accurate and realistic presentation
possible, thanks to digital audio technology. However,
you may wish to compress the dynamic range of the
audio output (the difference between the loudest sounds
and the quietest ones). Then, you may listen to a movie
at a lower volume without losing clarity of sound. Set
DRC to On for this effect.

Set Playback Control (PBC) to On or Off.

On: Video CDs with PBC are played according to the PBC.
Off: Video CDs with PBC are played the same way as Audio

CDs.

information that applies to the complete disc or to 
certain scenes on the disc. These scenes are rated
from 1 to 8, and alternatively, more suitable scenes are
available for selection on some discs. Ratings are 
area-dependent. The Parental Control feature allows
you to prevent discs from being played by your children
or to have certain discs played with alternative scenes.
