If the distance of D is equal to or longer than the D
S
in the left figure, set the Surround Delay Time as 0ms.
Otherwise, change the setting according to the 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
msec.
3m (D ) - 1.5m (D ) = 1.5m (B)
F S
1.5m (B) = 150cm / 30cm = 5msec
In Dolby Pro Logic II (Surround delay time):
Pro Logic: 15 ~ 30msec
Movie: 10 ~ 25msec
Music: 0 ~ 15msec

If the distance of DF is equal to the distance of DC in
the left figure, set the Center Delay Time as 0ms.

below.
Ex) If the distance from the front speakers to the
listener is 3m and from the center speaker to the
listener is 2.4m, the center delay time is 2msec.
3m (DF) - 2.4m (DC) = 60cm (A)
60cm (A) / 30cm = 2msec
