Delay Time
In the Dolby Pro Logic Surround modes (except 3CH Logic), the receiver
slightly delays the sound going to the rear speakers. You can change
this delay time from 15 to 30 milliseconds (ms) in 5 ms steps. Adjust the
delay time for the best surround effect. As a general guide, each step
corresponds to 3-5 feet in distance. For example, if the surround speak-
ers are 6 feet closer to you than the front speakers, try selecting 20 ms
setting.
Press
SURROUND,
then hold down
DELAY TIME
to change the delay time.
The receiver displays the selected time.
Effect Level
With DSP, you can change the delay time to alter the sound effect from
10 to 90. Press
SURROUND
, then hold down
– EFFECT
+
to change the effect
level.
The effect can vary depending on the source program.
Notes:
• You must use the remote control to
make these sound adjustments.
• Use the
VOLUME
control to adjust the
overall sound level.
