GENERAL SETUP
OFF
The AUDIO SETUP page provides three ad-
justment items that configure playback of digital
recordings. The first item activates or disables
the digital output. The second item sets the pa-
rameters for Dolby Digital dynamic range
compression. The third item sets a maximum
sampling rate for the digital output.
To reach the AUDIO SETUP PAGE, use
the CURSOR
buttons to highlight the
AUDIO SETUP line on the MAIN PAGE. Then,
press the PLAY/ENTER button.
To return to the MAIN PAGE, use the CUR-
SOR
buttons to scroll down and highlight
the MAIN PAGE line. Then, press the PLAY/
ENTER button.
The following instructions describe each ad-
justment item on the AUDIO SETUP PAGE and
the available settings. The default settings for
each item are shown in the illustration.
COMPRESS
When playing a Dolby Digital DVD-Video disc,
the RDV-1060 can compress the dynamic range
of the audio signal. This reduces the difference
between quiet sounds and loud sounds and
may be desirable if your system is taxed by
loud passages or for listening at low volumes.
The compression is quite sophisticated, using
instructions embedded in the digital data stream
To adjust, use the CURSOR buttons to select
a setting on the vertical slider control on the
right side of the menu screen. The “OFF” set-
ting provides no compression and the full
dynamic range of a Dolby Digital recording.
The “FULL” setting provides maximum avail-
able compression and reduces the dynamic
range of a Dolby Digital recording to that of
a typical VHS Hi-Fi recording. Settings in
between these two extremes provide progres-
sively more compression.
NOTE : This menu item only has an effect for
Dolby Digital recordings and is ignored for
other types of recordings
LPCM OUTPUT
The RDV-1060’s digital output can send an LPCM
(linear pulse code modulation) bitstream to the
receiver or surround processor. These LPCM
bitstreams can have different sampling rates,
depending on the format of the recording. For
example, Audio CDs generate a 44.1 kHz bit-
stream. A 2-channel LPCM soundtrack from a
DVD-Video disc generates a 48 kHz bitstream.
Some DTS DVD-Video discs generate a 96 kHz
bitstream. Since the bitstream must be decoded
by the receiver, it is important not to send a
signal that the receiver cannot process.
LPCM 48K: Choose this setting if your re-
ceiver cannot handle a digital bitstream with
a sampling rate higher than 48 kHz.
LPCM 96K: Choose this setting if your re-
ceiver can handle a digital bitstream with a
sampling rate up to 96 kHz. Even with this
default setting, a disc recorded with a 44.1
kHz or 48 kHz sampling rate will still be sent
to the receiver at the lower rate. This setting
simply specifies a maximum sampling rate.
NOTE : The RDV-1060 can process sampling
rates up to 192 kHz. However, this amount
of data cannot be sent to receivers or proces-
sors with the currently available digital con-
nections. These recordings must be decoded
and sent to the receiver as analog signals.
DIGITAL OUT
Use this setting to turn on or disable the digi-
tal bitstream sent from the RDV-1060’s coax
or optical digital outputs to a digital input on
the surround sound receiver or processor. In
most systems, this digital connection is the
preferred method of sending Dolby Digital or
DTS signals to the receiver, allowing the
receiver’s digital processors to decode the
multichannel signal.
STREAM/PCM: Use this setting to activate
the digital output.
OFF: Use this setting to disable the digital
output.
NOTE
: The digital bitstream is automatically
disabled when playing the PCM soundtrack
from a DVD-Audio disc.
