Getting the most out
of Dolby Pro Logic
Surround sound
To obtain the best possible Dolby Pro Logic Surround sound, you need
to adjust the delay time. The center mode and speaker levels were set in
EASY SET UP, so you don’t have to change those settings unless you
change the speaker configuration.
If you change the speaker configuration, see “Reconfiguring the
PROLOGIC and THEATER sound fields” on page 82.
Adjusting the delay time
You can make the surround sound more effective by delaying the
output from the rear speakers (delay time) relative to the front speakers.
You don’t have to adjust the delay time if you select 3CH LOGIC for
CENTER MODE.

Repeat steps 1 through 4 in
“Using the pre-programed sound
fields” on page 49 and select
PROLOGIC in step 3.
