Example of setting the time delay (Fig.4):
1.
Choose the system listening point.
To identify the listening point, choose an ideal point located at the
center of the listener’s (driver or passenger) head.
For the front center and rear center points choose an intermediate
point between the two (left / right) listeners.
2.
Measure the distance between each speaker or group of speakers
and the listening point in a straight line (“as the crow flies”).
For each speaker choose the center of the mobile membrane as
the emission point.
For groups of speakers choose an intermediate point between
them. It will then be possible to perform fine tuning by using the
Fine Set function.
(fig.6)
3.
Select the channel related to the speaker under examination on
the Channel Map and enter the respective distance value in the
Set Distance box of the Filter Settings menu.
(fig.5)
4.
Repeat step 3 for each channel.
5.
Perform all time delays settings, start playing music and select
the Fine Set box. As you move it positive or negative (except for
the Subwoofer in
Fig.6
since it is the farthest speaker), you will find
the best time alignment and correct acoustic scene.
It is advisable to listen to different types of music (percussion,
melodic, etc.) for a comprehensive evaluation of different musical
instruments (space stability.
6.
Once the time alignment procedure is complete, you can work
on the output equalizer
(see 8.12)
, to optimize the system response in
accordance with level alignment of different frequencies.
Remark:
measurements for the above operations can also be taken by
using a spectrum analyzer with an appropriate microphone.
The results must be assessed with final refining listening tests.
WARNING:
If, once you have set the distances for the “driver”
listening point, you click on the “passenger” listening point,
the
bit Ten
won’t re-calculate the delays for the new
reference point because the buttons available in the
SELECT A CHANNEL diagram are merely descriptive.
Their only purpose is to remind you that you have set the
delays for that listening point!
