Before Operation (Continued) Delay Time Setting In Dolby Digital or Dolby Pro Logic mode it is assumed that the distance from the listener to each of the speakers is equal. If not then setting the delay times of the center or rear speakers the sound will be heard simultaneously by the listener. The interval from the speakers to the listener. If the distance from the listener to each speaker is the same, in the Dolby Digital and Dolby Pro Logic mode the delay time of each speaker is as follows In Dolby Digital mode Center delay time : 0 ~ 5ms Rear delay time: 0 ~ 15ms In Dolby Pro Logic mode Center delay time : cannot be set If the rear delay time is set in Dolby Digital mode, in the Dolby Pro Logic mode the delay time will be automatically set. The delay time is 1 msec per 30 cm. If the Center and rear speakers are further than the front speakers from the listener, the delay time will be at minimum. Surround delay time setting L (A) R C DC DF SW DS SL SR (B) If the distance of DS is equal to or longer than the DF 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 (DF) - 1.5m (DS) = 1.5m (B) 1.5m (B) = 150cm / 30cm = 5msec In Dolby Pro Logic II (Surround delay time): Pro Logic: 15 ~ 30msec Movie: 10 ~ 25msec Music: 0 ~ 15msec Matrix: 0 ~ 15msec Center delay time setting (Dolby Digital mode only) If the distance of DF is equal to the distance of DC in the left figure, set the Center Delay Time as 0ms. Otherwise, change the setting according to the table 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 Setting the delay time in the Dolby Digital and Dolby Pro Logic (II) mode 1 Press DELAY.
