Delay Time Setting
■ In Dolby Digital or Dolby Pro Logic mode it is assumed that the time it takes the sound from each speaker to reach the
listener, is the same. But if the time interval from the center or rear left and right speakers to the listener is closer than the
time interval from the listener to the front left and right speaker, the sound of center or rear left and right speaker will
reach the listener first; instead of the sound of the front speakers. (It is desirable that the sound from the front speakers
reach the listener first.)
Dolby Digital and Dolby Pro Logic modes provide speaker time delay adjustments to resolve this problem:; you can
manually set the delay time of the center or rear left and right speakers so that the sound from all speakers will arrive
simultaneously to the listener.
1. Center delay time setting
If the distance of Dc is equal to or longer than the Df in the figure, set the mode to
0ms. Otherwise, change the setting according to the table below.
(A) = Df - Dc
2. Surround delay time setting
If the distance of Df is equal to the Ds in the figure, set the mode to 0ms.
Otherwise, change the setting according to the table below.
(B) = Df - Ds
3. Front delay time setting
If the distance of Ds or Dc is longer than the Df in the figure, change the setting
according to the table below. (C) = Ds or
Dc - Df
Ex) If the distance from front speakers to the listener is 3m and from rear speakers from the listener is 3.64m, Delay time of
the Front Speaker is 3.64m(Ds) - 3m(Df) = 0.64m (C), 0.64m (C)/0.34m=2ms.
If the Rear Speakers are closer, change the delay time of rear speaker.
