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 speak- ers is equal. If not then setting the delay times of the center or rear speakers the sound will be heard simulta- neously 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 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 automatical- ly 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.

		DC	DF

	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 listen- er 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
