Your SACD player is set to correctly reproduce
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 of the center and surround speakers 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. You can adjust the delay
time in the “User Preference Settings”. See Personal
preferences - Sound - Speaker Settings. 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.
