Adjust the time correction level of each speaker to almost the same level.

Sit in the listening position (driver’s seat, etc.) and

measure the distance (in meters) between your head

and the various speakers.

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.
