WARNING: If, once you have set the distances for the “driver”
listening point, you click on the “passenger” listening point,
AP8.9 bit won’t re-calculate the delays for the new reference
point because the buttons available in the SELECT CHANNEL
diagram are merely descriptive. Their only purpose is to
remind you that you have set the delays for that listening point!

5. Once the time delay settings are complete, start the
musical reproduction and use the Fine Set box, moving
the values up or down (except for the subwoofer since it
is the farthest speaker) to fine tune the system for
optimal sound. We recommend listening to various
types of music (percussion, melodic, etc.) for better
evaluation of the coherence (spatial stability) of the
different musical instruments.
6. Once the time alignment procedure is complete, you can
work on the output equalizer
(see sec. 7.3.12) to optimize
the system response based on the level alignment of the
various frequencies.
Remark: Measurements for the above operations can also
be taken using a spectrum analyzer with a suitable
microphone. The results must be evaluated and
optimized through listening tests.
