Adjust the time correction level of each speaker to almost the same level.
1
Sit in the listening position (driver’s seat, etc.) and
measure the distance (in meters) between your head
and the various speakers.
2
Calculate the difference between the distance
correction value to the farthest speaker and the
other speakers.
L = (distance to farthest speaker) – (distance to other
speakers)
These values are the time correction values for the different
speakers. Setting these values to make each sound reach the
listening position at the same time as the sound of other speakers.
