Adjusting the delay time (PRO LOGIC sound
field only)
You can make the surround sound more effective by
delaying the output from the rear 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 rear speakers in a large room or apart from
your listening position, set the delay time shorter.
