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 to
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.
