Using Surround Sound
Adjusting the delay time
(PRO LOGIC sound field only)
You can make the surround sound more effective by
delaying the output from the surround speakers (delay
time). You can select from three delay times, S (15 mS),
M (20 mS), and L (30 mS). For example, if you've
placed the surround speakers in a large room or apart
from your listening position, set the delay time shorter.
