feed to the CVR700 or to select between
Dolby Digital or DTS. It is also possible
for the type of signal feed to change dur-
inh the course of a DVD’s playback. In
some cases, the previews or special
material will be recorded in 2.0 audio,
while the main feature is available in 5.1
audio. The CVR700 will automatically
sense changes to the bitstream and chan-
nel count and reflect them in these indi-
cators.
The letters used by the Speaker/
Channel Input Indicators F also flash
to indicate when a bitstream has been
interrupted. This will happen when a digi-
tal input source is selected before the
playback starts, or when a digital source
such as a DVD is paused. The flashing
indicators remind you that the playback
has stopped due to the absence of a digi-
tal signal and not through any fault of the
CVR700. This is normal, and the digital
playback will resume once the playback
is started again.
When a 6.1-channel mode, such as Dolby
Digital EX, is detected, a line will appear
connecting the SBL and SBR channels to
reflect that the same signal is being out-
putted through both back surround chan-
nels. The line will disappear when a 7.1-
channel mode, such as Logic 7, is in use.
At this time, there are no 7.1-channel dig-
ital formats available.
Night Mode
A special feature of Dolby Digital is the
Night mode, which enables specially
encoded Dolby Digital input sources to be
played back with full digital intelligibility
while reducing the minimum peak level
by 1/4 to 1/3. This prevents abruptly
loud transitions from disturbing others,
without reducing the impact of the digital
source. The Night mode is available only
when Dolby Digital signals with special
data are being played.
The Night mode may be engaged when a
Dolby Digital DVD is playing by pressing
the Night Mode Button
Z on
the remote. Next, press the ⁄ / ¤
Navigation Button q to select
either the middle range or full compres-
sion versions of the Night mode. To turn
the Night mode off, press the
⁄ / ¤
Navigation Button q until the
message in the lower third of the video
display and in the Lower Display Line
E reads NIGHT MODE OFF.
The Night mode may also be selected to
always be on at either level of compres-
sion using the options in the
DOLBY
SURROUND menu. See page 47 for
information on using the menus to set
this option.
MP3 and WMA Compressed
Audio Playback
The CVR700 is one of the few audio/
video components equipped with onboard
decoding of the MP3 and WMA audio
formats used by computers and portable
audio devices. By offering MP3 and WMA
decoding, the CVR700 is able to deliver
precise conversion of the digital signals
to an analog output, along with the bene-
fits of listening to the MP3 or WMA
audio through the CVR700’s high-power
amplifier and the speakers from your sur-
round system, rather than the smaller
speakers and low-powered amplifiers
typically used with computers.
To take advantage of the CVR700’s MP3
and WMA capabilities, simply insert a
disc containing MP3 or WMA audio files
into the changer drawer. When the digital
signal is available, the Lower Display
Line E will indicate that an MP3 or
WMA bitstream is present, and the audio
will begin playing.
NOTES:
• The CVR700 is only capable of playing
signals in the MP3 (MPEG 1/Layer 3)
format, or in the Windows Media
Audio (WMA) format compatible with
Windows Media player version 9 or
greater. It is not compatible with other
computer audio codecs.
• Due to the wide variation in MP3 and
WMA formats and encoding speeds,
it is possible that the CVR700 may not
be compatible with all MP3 or WMA
files. Some may produce unacceptable
results or may not be decoded. This is
not a fault of either the computer or
the CVR700, but rather a by-product of
the unpredictable nature of compressed-
audio playback.
• Even when your computer does not
have a digital output that is compatible
with the CVR700, you may connect the
analog audio output available on virtu-
ally all computers to one of the analog
audio inputs using an optional adaptor
cable that converts the stereo mini
plug commonly used for computer
audio connections to the left/right RCA
jacks used on the CVR700. Connecting
your computer to the CVR700 will
enable you to take advantage of the
high-quality audio reproduction possi-
ble with a home theater system, as
well as enable the use of surround pro-
cessing modes such as Logic 7, to
greatly enhance downloaded or
streaming audio playback.
IMPORTANT NOTES ON DIGITAL
PLAYBACK:
• When the digital playback source is
stopped, or in a pause, fast forward or
search mode, digital audio data will
momentarily stop, and the channel
position letters inside the Speaker/
Channel Input Indicators F
will
flash. This is normal and does not indi-
cate a problem with either the CVR700
or the source machine. The CVR700
will return to digital playback as soon
as the data is available.
• Some source devices, particularly cable
set-top boxes, will switch back and
forth between digital and analog audio
outputs, depending on the channel
being watched. To avoid losing sound
with this type of product, it is recom-
mended that you connect both the digi-
tal and analog audio outputs of the
source to the CVR700, with the digital
audio input set as the default following
the steps shown on page 46. If the dig-
ital data stream is interrupted and the
sound mutes, you will need to manually
switch to the analog audio input by
pressing the Audio Input Button
k
and using the ⁄ / ¤
Navigation Buttons q to
select the analog audio input for the
current source. Press the Set Button
s
to enter your selection and
return to normal operation. When
switching to a digital channel, follow
the same procedure, except select the
appropriate digital audio input for the
source. This switching is not a fault of
either the CVR700 or the cable box,
as it is caused by the use of different
audio technologies on different chan-
nels by the cable company or program
supplier.
• Although the CVR700 will decode virtu-
ally all current DVD movies, CDs and
HDTV sources, it may not be compatible
with future digital sources.
• When a digital source is playing, you
may not be able to select some of the
analog surround modes such as Dolby
Pro Logic II, Dolby Pro Logic IIx, Hall,
Theater or Logic 7.
• When a Dolby Digital or DTS
source is playing, it is not possible
to make an analog recording using
the Digital Recorder Analog
Audio/Video Outputs ‚ or the
