Adjusting the delay time:
When enjoying 5.1ch surround playback, it is ideal
to choose a listening position that is the same
distance from each speaker. By adjusting the
delay time of the center/surround speakers, you
can virtually create an ideal listening environment
(as if the center/surround speakers were at their
ideal locations respectively as below.)
Center Channel Delay
0msec: When Df equals Dc.
1msec: When (A) is approx. 34 cm (13 inch)
2msec: When (A) is approx. 68 cm (27 inch)
3msec: When (A) is approx. 102 cm (40 inch) . . .
*(A) = Df – Dc
Get your optimum value (0, 1, 2 . . . 5)
dividing (A) by 34.
Surround Channel Delay
0msec: When Df equals Ds.
1msec: When (B) is approx. 34 cm (13 inch)
2msec: When (B) is approx. 68 cm (27 inch)
3msec: When (B) is approx. 102 cm (40 inch) . . .
*(B) = Df – Ds
Get your optimum value (0, 1, 2 . . . 15)
dividing (B) by 34.
Note
Depending on the sound in a DVD audio disc, the
DVD player may adjust delay time as “0msec,”
regardless of your delay time settings.
