In the main unit’s normal mode, 7-bands can be adjusted with a parametric equalizer.

Time Alignment

With vehicle audio systems, the installation position of the speakers and the position of the listener
mean that the distances from the listener to the left and right speakers are almost always different.
These differences in the distance from the listener to each speaker in turn means that the time taken
for the sound to reach the listener is different for each speaker. The result of this is that the phases
of each speaker (biases) become mismatched and the sound becomes unnatural, as though the
sound stage is not wide enough.
