How to operate the Sound Adjustment Mode
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.
The "time alignment" function corrects the time taken for the sound
waves to reach the listener in order to set the optimum phase for the
listening position so that the sound becomes more expansive as
though it is being listened to on a sound stage.
The basic adjustment method involves measuring the actual
distances to each speaker and calculating the differences in
distance relative to the most distant speaker in order to derive the
delay time for the sound from each speaker.
When this deck is in normal mode, a simplified time alignment
function is available. You can use this function to adjust only four
parameters (position selector, vehicle type, tweeter settings and
rear speaker position settings), and so you can make basic time
alignment settings without measuring the actual distances to each
speaker. In addition, in pro mode you can adjust the time delays and
levels for each individual speaker based on the actual speaker
layout.
