cannot send a Dolby Digital bitstream to a two-
channel preamp designed only to accept a
PCM signal from a CD player. Likewise, there
is no point in sending a DTS bitstream to a
surround processor that does not have DTS
processing. This preference setting ensures that
the digital data stream from the digital output
of the RDV-1080 matches the preamp or pro-
cessor it is sent to. The RDV-1080 sends com-
patible signals and converts other types of digi-
tal signals to formats specified in the setting.
There are three available settings. The specif-
ics of what digital output format is sent for each
setting and each type of program material is
supplied in the table shown in Figure 5.
To set the DIGITAL OUTPUT MODE:
• On the PREFERENCE 2 screen, use the
CURSOR buttons to move the over
the DIGITAL OUTPUT MODE item.
• Press the CURSOR buttons to choose
the desired setting.
PCM ONLY: Supplies only a linear PCM
digital signal. Use this setting with preamps
expecting a bitstream from an CD Player.
STREAM/PCM: Supplies almost all pos-
sible digital formats to the outputs without
conversion. Use with surround processors
that have DTS, Dolby Digital, and MPEG
processing. In this configuration, you will
be using the surround processor’s digital
processing instead of the RDV-1080’s.
DOLBY DIGITAL/PCM: Supplies a Dolby
Digital or PCM digital output signal. Use
with surround processors that have Dolby
Digital processing, but not DTS or MPEG
processing.
NOTE : If the DIGITAL AUDIO OUTPUT mode
is set to “STREAM/PCM”, the speaker set-
tings described later in the manual are dis-
abled. Use the settings on the surround
processor to configure your speakers.
DOWN MIX Mode
The RDV-1080 can provide fully decoded 5.1
channel surround signals at the analog audio
outputs. To take full advantage of this decoded
signal, the preamp or amplifier receiving it
should be equipped with 5.1 channel analog
audio inputs. If not, the RDV-1080 can
“downmix” the full surround sound signal to
a signal the preamp or surround processor can
handle. This setting only affects the analog
output signal when playing a DVD Video disc
with multichannel surround audio. Choose the
setting that best matches your system.
To change DOWN MIX MODE setting:
• On the PREFERENCE 2 screen, use the
CURSOR buttons to move the over
the DOWN MIX MODE item.
• Press the CURSOR buttons to choose
the desired setting.
Lt/Rt: Downmixes the full 5.1 channel sig-
nal into an encoded 2-channel surround
signal. Use this setting to send the analog
audio signal to a surround sound decoder
that has analog surround processing (such
as Dolby
® Pro Logic ® ), but does not have
5.1 channel analog inputs.
Lo/Ro: Downmixes the 5.1 channel sig-
nal to a conventional 2-channel stereo sig-
nal. Use this setting to send the analog audio
signal to a preamp, TV, or recorder with
conventional two-channel stereo input and
no surround sound decoding capability.
OFF: Supplies the full 5.1 channel signal to
the analog audio outputs. Use this setting for
surround processors that have 5.1 channel
audio inputs. This setting must be used when
you select the 5.1 CHANNEL or EXPERT set-
ting in the SPEAKER SETTING preferences.
NOTE
: The DOWN MIX feature does not work
when the VSS function is activated.
COMPRESSION Setting
When playing a Dolby Digital DVD Video Disc,
the RDV-1080 can compress the dynamic range
of the audio signal. This reduces the difference
between quiet sounds and loud sounds. It may
be desirable if your system is routinely taxed
by loud passages or for listening at low vol-
ume settings. Choose the setting that best
matches your system.
To change the COMPRESSION setting:
• On the PREFERENCE 2 screen, use the
CURSOR buttons to move the over
the COMPRESSION item.
• Press the CURSOR buttons to choose
the desired setting.
ON: Activates the Compression feature
(only for DVD Video Discs with Dolby Digital
recordings).
OFF: No compression. Full dynamic range.
DTS BASS MANAGEMENT Setting
Settings described later in this section enable
you to match the RDV-1080’s 5.1 channel audio
output to the specific capabilities of your speak-
ers (i.e. for large or small speakers.) This set-
ting gives you the option to override these
settings and treat all speakers as “large” when
playing DTS-encoded disc. This setting only
functions when playing a DTS disc; the default
speaker settings are in effect for all other discs.
To change the setting:
• On the PREFERENCE 2 screen, use the
CURSOR buttons to move the over
the DTS BASS MANAGEMENT item.
• Press the CURSOR buttons to choose
the desired setting.
OFF: This is the default setting for DTS re-
cordings. Overrides the speaker settings
and treats all speakers as “large”.
ON: All speaker settings are effective, even
when playing a DTS recording. Although
this setting will not match the full DTS speci-
fication, it may be preferred if you have
small speakers that cannot handle signifi-
cant bass information.
AUTO STANDBY Setting
The RDV-1080 has an Auto Standby feature
that will put the unit in standby mode follow-
ing either 30 or 60 minutes of inactivity.
To change the setting:
• On the PREFERENCE 2 screen, use the
CURSOR buttons to select the AUTO
STANDBY item.
• Press the CURSOR buttons to choose
the desired setting.
60: Puts the unit in standby mode after 60
minutes of inactivity.
30: Puts the unit in standby mode after 30
minutes of inactivity.
OFF: The Auto Standby function is disabled.
The unit will stay on until it is manually put
in standby mode.
