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.
