–10 to +6, but you can shift the range up 3 levels (–7 to
+9). Hold down SOUND FIELD on the amplifier while
turning on the power until “NORMAL” appears on the

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
