OPERA TION 31
Operation
is important to note that although Dolby Digital,
for example , is referred to as a “5.1” system, not
all Dolby Digital DVD or audio tracks selected on
DVD or other Dolby Digital programs are encod-
ed for 5.1. Thus , it is sometimes normal for a
DVD with a Dolby Digital soundtrack to trigger
e .g. only the “L ” and “R” indicators .
NO TE: Many DVD discs are recorded with both
“5.1” and “2.0” versions of the same sound-
track, the ”2.0” version often is used with other
languages . When playing a DVD , always be cer-
tain to check the type of material on the disc.
Most discs show this information in the form of a
listing or icon on the back of the disc jack et.
When a disc does offer multiple soundtrack
choices you may have to mak e some adjustments
to your DVD player (usually with the “ Audio
Select” button or in a menu screen on the disc)
to send a full 5.1 feed to the A VR 4000 or to
select the appropriate audio track and thus lan-
guage (”2.0” audio tracks can be played with all
surround modes , even with Logic 7, see indicator
”PCM” on page 30). It is also possible for the
type of signal feed to change during the course
of a DVD playback. In some cases the previews
of special material will only be recorded in 2.0
audio , while the main feature is available in 5.1
audio . As long as your DVD player is set for 6-
channel output, the A VR 4000 will automatically
sense changes to the bitstream and channel
count and reflect them in these indicators .
T he letters used by the Speaker/Channel Input
Indicators
Q
also flash to indicate when a bit-
stream has been interrupted. This will happen
when a digital input source is selected before the
playback starts , or when a digital source such as
a DVD is put into a P ause mode. The flashing
indicators remind you that the playback has
stopped due to the absence of a digital signal
and not through any fault of the A VR. This is nor-
mal, and the digital playback will resume once
the playback is started again.
Night Mode
A special feature of Dolby Digital is the Night
mode , which enables Dolby Digital input sources
to be played back with full digital intelligibilty
while reducing the maximum peak level and lift-
ing the low levels by
1/ 4 to 1/ 3. T his prevents
abruptly loud transitions from disturbing others
without reducing the impact of the digital source .
T he Night mode is available only when Dolby
Digital mode is selected.
T he Night mode may be engaged when a Dolby
Digital DVD is playing by pressing the Night
Button
B
on the remote . Next, press the ⁄/ ¤
buttons
D
to select either the middle range or
full compression versions of the Night mode . T o
turn the Night mode off , press the
⁄/ ¤ buttons
D
until the message in the lower third of the
video display and the Main Information
Display
Y
reads D-RANGE OFF. When
the Night mode is active , the Night Mode
Indicator
O
will also illuminate .
T he Night mode may also be selected to always be
on at either level of compression using the options
in the Surround Setup Menu. See page 24 for
information on using the menus to set this option.
IMPORT ANT NO TES ON DIGIT AL PLA YBA CK:
1. When the digital playback source is stopped,
or in a pause , fast forward or chapter search
mode , the digital audio data will momentarily
stop , and the channel position letters inside the
Speaker/Channel Indicators
Q
will flash.
T his is normal and does not indicate a problem
with either the A VR 4000 or the source machine .
T he A VR 4000 will return to digital playback as
soon as the data is available and when the
machine is in a standard play mode .
2. Although the AVR 4000 will decode virtually all
DVD movies , CDs and HDTV sources , it is possible
that some future digital sources may not be com-
patible with the A VR 4000.
3. Note that not all digitally encoded programs
and not all audio tracks on a DVD contain full
5.1-channel audio . Consult the program guide
that accompanies the DVD or laser disc to deter-
mine which type of audio has been recorded on
the disc. The A VR 4000 will automatically sense
the type of digital surround encoding used, indi-
cate it in the Bitstream Indicators
A
and
Channel Input Indicators
Q
and adjust to
accommodate it.
4. When a Dolby Digital or DTS source is playing,
you normally may not be able to select some of
the analog surround modes such as Dolby Pro
Logic, Dolby 3, Stereo , Hall, Theater , 5CH Stereo
or Logic 7, except with special audio tracks
(see indication ”Dolby Digital” on previous page)
or data format selected (see ”PCM” on previous
page).
5. When a Dolby Digital or DTS source is playing,
it is not possible to mak e an analog recording
using the T ape
1
or Video 1 or V ideo 2 or
4W
record outputs , if the source is connected
to any digital input of the A VR4000 only . But the
analog two channel signal of that source , the
”Downmix” to Stereo or Dolby Surround, can be
recorded by connecting its analog audio outputs
to the appropriate analog inputs (e .g. DVD) of
the A VR4000, even if the digital input of the
A VR4000 remains selected. Additionally , the digi-
tal signals will be passed through to the Digital
Audio Outputs
T
.
T ape Recor ding
In normal operation, the audio or video source
selected for listening through the A VR 4000 is
sent to the record outputs . T his means that any
program you are w atching or listening to may be
recorded simply by placing machines connected
to the outputs for T ape Outputs
1
or Video 1
or 2 Outputs
4MP
in the record mode .
When a digital audio recorder is connected to
any of the Digital Audio Outputs
T
, you are
able to record the digital signal using a CD-R,
MiniDisc or other digital recording system.
Note that all digital signals will be passed
through to both, coaxial and optical, digital out-
puts simultanously , no matter which kind of digi-
tal input was selected.
In addition to the rear panel digital outputs , the
A VR 4000 offers Harman Kardon’ s exclusive con-
figurable front panel digital output feature . F or
easy connection of portable digital audio
recorders , you may switch the front panel
Coaxial Digital Jack
%
from an input to an
output by following these steps:
1. Press the OSD button
L
to view the main
MASTER MENU (Figure 1).
2. Press the Set button
F
to enter the
IN/OUT SETUP menu (Figure 2).
3. Press the
¤
button
D
twice so that the on-
screen
› cursor is next to COAXIAL 3.
4. Press either of the
‹/ › buttons
E
/
U
so
that the word OUT is highlighted.
5. Press the OSD button
L
to exit the menus
and return to normal operation.
Note that once the setting is made , the Digital
Coax 3 Status Indicator
$
will turn red, indi-
cating that the Coaxial 3 Jack
%
is now an
output, instead of its default setting as an input.
Once the jack is changed to an output, the set-
ting will remain as long as the A VR 4000 is
turned on, unless the setting is changed in the
OSD menu system, as described above . Note ,
however , that once the A VR 4000 is turned off ,
the setting is cancelled. When the unit is turned
on again, the Coaxial 3 Jack
%
will return to
its normal default setting as an input. If you wish
to use the jack as an output, the setting must be
changed again using the OSD menu system.
NO TES:
• T he digital outputs are active only when a digital
signal is present, and they do not convert an ana-
log input to a digital signal, or change the format
of the digital signal (e .g. Dolby Digital to PCM or
vice versa, but coaxial digital signals are converted
to optical signals and vice versa). In additon, the
digital recorder must be compatible with the out-
put signal. F or example, the PCM digital input
