Delay times
The DVD player is set to reproduce correctly synchronized Digital
Surround Sound in a listening area where the surround speakers are
about 150cm nearer to the listening position than the front speakers, and
the center speaker is in line with the front speakers.To adjust for other
listening area arrangements, adapt delay times according to the following:
Digital Surround
Measure the distances in centimeters from the front speaker plane and
from the surround speaker plane to the listening positioning plane.
Subtract the surround distance from the front distance and divide by 30.
The result is the required Surround Channel delay time in milliseconds.
If the center speaker is on the front speaker plane, no center speaker
delay is needed. If, however, it is nearer the listening position, measure
the distance in centimeters between the front and center speaker
planes, and divide by 30.The result is the required Center Channel delay
time in milliseconds.
Dolby Surround
Add 15 milliseconds to the Surround  Channel delay time calculated for
Digital Surround.
If the Center Channel in Digital Surround mode is set, add 15 millisec-
onds to the Center Channel delay time.
