and the surround speakers are 1 m away, the
optimal delay time is figured as
(3–1)x3+15=21.Thus, in this example, the
Pro Logic delay should be set at twenty mil-
liseconds.
NOTE: The DTS, Logic 7, 5CH Stereo, Hall and
Theater modes use a fixed, nonadjustable delay
time.
The Dolby Digital Mode also includes a separate
setting for the center channel delay mode, since
the discrete nature of these signals makes the
location of the center channel speaker more crit-
ical.To calculate the delay for the center chan-
nel, measure the distance from the preferred lis-
tening position in the center of the room to both
the center channel speaker and either the left or
right speaker.
If the distances are equal, no further adjustment
is required and the center delay should be set to
zero. If the distance to the front speakers is
greater than the distance to the center speaker,
you may wish to reposition the speakers by mov-
ing the front left and front right speakers closer
to the listening position or the center speaker
further away from the listening position.
If repositioning of the speakers is not possible,
adjust the center delay time, adding one milli-
second of center channel delay for every 30 cm
closer to the listening position the center speak-
er is than the front speakers. For example, if the
front left and front right speakers are each 3 m
from the listening position and the center chan-
nel speaker is 2.4 m away, the delay is figured as
300 cm –240 cm=60 cm, suggesting an optimal
center delay of 2 milliseconds.
To set the delay time, continue within the
MASTER MENU (Figure 1). If the system
is not already at that point, press the OSD but-
ton
L
to bring up the master menu.To make
the delay settings for the Dolby Digital mode
(this will include the Center delay setting, and
the surround delay for the Pro Logic mode will
be set automatically), press the Set
F
button
and select any input now that is associated with
a digital input and the Dolby Digital surround
mode (the surround mode associated with each
input selected will be indicated by the
Surround Mode Indicators
˜
in the front
panel), then return to the master menu. Press
the
¤ button
D
and then the Set button
F
to bring up the surround setup menu, now press
the

once.
As the Dolby Digital mode is selected, the
› cur-
sor will stop at the CENTERDELAY
line. Press the
‹/› buttons
EU
until the
number calgulated using the formula shown
above appears in the disply. When the
CENTERDELAY is entered, press the
¤
button
D
once to move to the SURR
DELAYline so that the delay for the sur-
round speakers may be set. Press the
‹/› but-
tons
EU
until the desired figure appears in
the display, using the number calculated using
the formula shown above for the Dolby Digital
surround mode (item 3a).When the delay set-
tings are complete, press the

once to move to the next line.
Note that the delay settings may also be adjust-
ed at any time when the Dolby Digital or Dolby
Pro Logic modes are in use by pressing the

Night Mode Settings
The Night mode is a feature of Dolby Digital that
uses special processing to preserve the dynamic
range and full intelligibility of a movie sound
track while reducing the peak level.This prevents
abruptly loud transitions from disturbing others,
without reducing the sonic impact of a digital
source. Note that the Night mode is only avail-
able when Dolby Digital signals are played.
To adjust the Night mode setting from the
menu, make certain that the
› cursor is on the
Night line of the SURROUNDSETUP
menu. Next, press
‹/› buttons
EU
to
choose between the following settings.
OFF: When OFF is in the highlighted video,
the Night mode will not function.
MID: When MID is in the highlighted video, a
mild compression will be applied.
MAX: When MAX is in the highlighted video, a
more severe compression algorithm will be
applied.
We recommend that you select the MID setting
as a starting point and change to the MAX set-
ting later, if desired.
Note that the Night mode may be adjusted
directly any time that a Dolby Digital source is
playing by pressing the Night button
B
.
When the button is pressed, the words
D-RANGEwill appear in the lower third of
the video screen and in the Main Information
Display Y. Press the
⁄/¤ button
D
within
three seconds to select the desired setting, then
press Set
F
to confirm the setting.
When all settings for the surround setup have
been made, press the
⁄/¤ buttons
D
so that
the
› cursor is next to RETURN TO
MENU, and press the Set button
F
to
return to the master menu.
Output Level Adjustment
Output level adjustment is a key part of the con-
figuration process for any surround sound prod-
uct. It is particularly important for a Dolby Digital
receiver such as the AVR5000, as correct outputs
will ensure that you hear sound tracks with the
proper directionality and intensity.
NOTE: Listeners are often confused about the
operation of the surround channels. While some
assume that sound should always be coming
from each speaker, most of the time there will
be little or no sound in the surround channels.
This is because they are only used when a
movie director or sound mixer specifically places
sound there to create ambiance, a special effect
or to continue action from the front of the room
to the rear. When the output levels are properly
set it is normal for surround speakers to oper-
ate only occasionally. Artificially increasing the
volume to the rear speakers may destroy the
illusion of an enveloping sound field that dupli-
cates the way you hear sound in a movie the-
ater or concert hall.
IMPORTANT NOTE: The output level can be
adjusted for each digital and analog surround
mode separately. This allows you to compensate
for level differences between speakers, that may
also vary with the surround mode selected, or to
increase or decrease the level of certain speakers
intentionally, depending on the surround mode
selected.
Before beginning the output level adjustment
process, make certain that all speaker connec-
tions have been properly made. The system
volume should be turned down at first. Finally,
make certain that the Balance Control
*
is
set to the center “12 o’clock” position.
