Speaker Sound Delay Time Setting
In Dolby Digital or Dolby Pro Logic mode it is assumed
that the distance from the listener to each of the speak-
ers is equal. If not, then set the delay times of the cen-
ter or rear speakers so that the sound will be heard
simultaneously by the listener.
The interval from the speakers to the listener. If the dis-
tance from the listener to each speaker is the same, in
the Dolby Digital and Dolby Pro Logic mode, the delay
time of each speakers is as follows.
In Dolby Digital mode
Center delay time : 0 ms
Rear delay time: 5 ms
In Dolby Pro Logic mode
Center delay time : cannot set
Rear delay time : 15-30 ms
If the rear delay time is set in Dolby Digital mode, in the
Dolby Pro Logic mode, the delay time is set automatical-
ly.
The delay time is 1 ms per 30 cm.
If the center and rear speakers are further than the front
speakers from the listener, the delay time will be at min-
imum.

Surround delay time setting
If the distance of D
is equal to or longer than the D

the left figure, set the Surround Delay Time as 0 ms.
Otherwise, change the setting according to the table
below.
Ex) If the distance from front speakers to the listener is
3 m and from rear speakers from the listener is 1.5 m,
in the Dolby Digital mode, the rear delay time is 5 ms.
3 m (D
) - 1.5 m (D
) = 1.5 m (B)

1.5 m (B) = 150 cm / 30 cm = 5 ms
In Dolby Pro Logic II (Surround delay time):
Emulation: 10 ~ 25 ms
Movie: 10 ~ 25 ms
Music: 0 ~ 15 ms
Virtual: cannot set
Matrix: 0 ~ 15 ms

Center delay time setting
If the distance of DF is equal to the distance of DC in
the figure shown above, set the Center Delay Time as 0
ms. Otherwise, change the setting according to the fol-
lowing table.
Ex) If the distance from the front speakers to the listen-
er is 3 m and from the center speaker to the listener is
2.4 m, the center delay time is 2 ms.
3 m (DF) - 2.4 m (DC) = 60 cm (A)
60 cm (A) / 30 cm = 2 ms

Center Width
(MUSIC mode of Dolby Pro Logic II only)
This control allows center-channel sounds to be posi-
tioned between the center speaker and the left/right
speakers over a range of eight steps. Step "3" uses a
combination of all three front speakers to give the best
vocal imaging and most seamless soundstage presen-
tation, and is recommended for most recordings. Step
"0" places all center sound in the center speaker. Step
"7" places all center sound equally in the left/right
speakers, just as in conventional stereo.
DIMENSE
(MUSIC mode of Dolby Pro Logic II only)
This control allows the user to gradually adjust the
soundfield either towards the front or the rear. This can
be useful to help achieve the desired balance from all
the speakers with certain recordings that may contain
either too much or too little spatial effect. Step "0" is the
recommended setting, which has no effect on the
sound. Steps 1, 2, and 3 gradually move the sound for-
ward, and steps –1, –2, and –3 move the sound
towards the surrounds.
PANORAMA
(MUSIC mode of Dolby Pro Logic II only)
This control extends the front stereo image to include
the surround speakers for an exciting "wraparound"
effect with side-wall imaging. It is particularly effective
for recordings which have strong left- or right-channel
elements in the mix, as these are detected and accen-
tuated by the Panorama process.
(Dolby Digital mode only)
