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.
Dolby Pro Logic
If the delay times for Surround Channel and
Center Channel are set for Digital Surround
mode, the delay times for Dolby Pro Logic mode
will automatically be calculated and set.
