Determining the value for <Position/DTA>
adjustment
If you specify the distance from the center of the
currently set listening position to every speaker, the
delay time will be automatically computed and set.
1 Determine the center of the currently set
listening position as the reference point.
2 Measure the distances from the reference point
to the speakers.
3 Calculate the differences between the distance of
the furthest speaker and other speakers.
4 Set the DTA value calculated in step 3 for
individual speakers.
5 Adjust gain for individual speakers.
