Setting Delays
In Dolby Digital and Dolby Pro Logic mode, it is
assumed that the distance from the listener to each of
the five speakers is equal. If your center and rear
speakers are closer than the front speakers, you can
set delays so that sound from these speakers will be
heard simultaneously at your primary listening position.
In Dolby Digital mode
Center delay time : 0ms
Rear delay time: 5ms
In Dolby Pro Logic mode
Center delay time : cannot be set
Rear delay time : 0-15ms
If the rear delay time is set in Dolby Digital mode, the
delay time will be automatically set in Dolby Pro Logic
mode .
The delay time is approximately 1 msec per foot.
If the center and rear speakers are further than the front
speakers from the listener, the delay time should be set
to the minimum.
Surround delay time setting
If the distance from your rear speakers to the listener is
the same or greater than your front speakers, set the
Surround Delay Time to 0ms. Otherwise, change the
setting according to the calculation below.
For example, if the distance from the front speakers to
the listener is 10 feet and from the rear speakers to the
listener is 5 feet, the rear delay time would be 5 msec.
10 feet - 5 feet = 5 feet, or 5msec
In Dolby Pro Logic II (Surround delay time):
PROLOGIC: 10 - 25msec
MOVIE: 10 - 25msec
MUSIC: 0 - 15msec
VIRTUAL: cannot be set
MATRIX: 0 - 15msec
Center delay time setting
(Dolby Digital mode only)
If the distance from your center speaker to the listener
is the same or greater than your front speakers, set the
Center Delay Time to 0ms. Otherwise, change the set-
ting according to the calculation below.
For example, if the distance from the front speakers to
the listener is 10 feet and from the center speaker to
the listener is 8 feet, the center delay time is 2msec.
10 feet - 8 feet = 2 feet, or 2msec

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
sound field 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.
