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 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.
