Adjusting the delay time
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.
