• Before making an adjustment for [DISTANCE] and [GAIN] of [DTA SETTINGS],
select the speaker you want to adjust:
[FRONT LEFT]/[FRONT RIGHT]/[REAR LEFT]/[REAR RIGHT]/[SUBWOOFER]
– You can only select [REAR LEFT], [REAR RIGHT] and [SUBWOOFER] if a setting
other than [NONE] is selected for [REAR] and [SUBWOOFER] of [SPEAKER SIZE].

Determining the delay time automatically
If you specify the distance from the currently set
listening position to every speaker, the delay time
will be automatically calculated.
1 Set [POSITION] and determine the listening
position as the reference point (the reference
point for [FRONT ALL] will be the center
between the right and left in the front seats).
2 Measure the distances from the reference point to
the speakers.
3 Calculate the distance between the furthest
speaker (subwoofer on the illustration) and other
speakers.
4 Sets the [DISTANCE] calculated in step 3 for
individual speakers.
5 Adjusts [GAIN] for individual speakers.
Example: When [FRONT ALL] is selected as the
listening position.
