2. Measure the distance from the listening/ view-
ing position to the surround speakers.
3.Subtract the distance to the surround speakers
from the distance to the front speakers and mul-
tiply the result by 3.
The optimal delay time is the result of that sub-
traction.For example, if the front speakers are 3
m away and the surround speakers are 1 m away,
the optimal delay time is figured as (3–1)x3=6.
Thus, in this example, the delay time for Dolby
Digital should be set at six milliseconds.
NOTE: The DTS, Logic 7,5/7CH 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 criti-
cal.To calculate the delay for the center channel,
measure the distance from the preferred listening
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-sec-
ond of center channel delay for every 30 cm clos-
er to the listening position the center speaker 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 channel
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 button
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 sur-
round delay for the Pro Logic mode will be set
automatically), press the Set

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
available when the Dolby Digital surround mode
is selected.
To adjust the Night mode setting from the menu
press the OSD Button
L
so that the
MASTERmenu appears.Then press the
¤
button
D
once and press Set
F
to select
the SURROUNDSETUPmenu.Again
press the
¤
button

once and press Set
F
to select the DOLBYmenu (see fig.7).
