To set the delay time
When 5.1 Channel Surround Sound is played, you can enjoy the
best sound if the distance between you and each speaker is the
same. You can set Delay Time in the Center/Rear Speaker to
customize the sound to the acoustics of your room.
Setting Center Speaker
If the distance of Dc is equal to or longer than the distance of Df in
the figure, set the mode as 0ms.
Otherwise, change the setting according to the table on the table.
Setting Rear Speakers
If the distance of Df is equal to the distance of Ds in the figure, set
the mode as 0ms.
Otherwise, change the setting according to the table.

Speaker Setting Methods
Front Speakers
Set the front speakers so that their tweeters (high-range) are aligned
at about ear level and at a horizontal angle of 45° to the prime
listening position.
Center Speaker
Ideally the center speaker should be positioned with its top surface
flush with the front speakers. However, you may place the speaker
either on top or near the bottom of your TV set.
Rear Speakers
Set the rear speakers further back parallel to the walls, at 60 to 90
centimeters (2 to 3 feet) above prime listening position ear level.
If the space behind the listening position is insufficient (i.e., too
close to the wall), place the rear speakers facing each other on
either side.
Subwoofer Speaker
Place the subwoofer at any convenient location within the vicinity of
the listening position.
