If the distances are equal, no further
adjustment is required, and the center
delay should be set to zero. If the
distance to the front speakers is greater
than the distance to the center speaker
you may wish to reposition the speakers
by moving the front left/right speakers
closer to the listening position or the
center speaker further away from the
listening position.
If repositioning of the speakers is not
possible, adjust the center delay time
so that you add one millisecond of center
channel delay for each foot that the dis-
tance to the center speaker lags behind
the front speakers. For example, if the
front left/right speakers are each 10 feet
from the listening position and the
center channel speaker is 8 feet away, the
delay is figured as 10-8=2, suggesting an
optimal center delay of 2 milliseconds.
