Performing time correction automatically
(Automated Time Correction)
Due to the particular conditions inside the vehicle, there is a major difference between the distances
of the various speakers and the listening position. This function uses the included measurement
microphone to automatically measure and analyse the distances between the speakers and the
listening position and perform the optimum time correction.
• Preparations must be made before performing the automatic adjustment procedure. Refer
to page 12.
• The PXI-H990’s automatic adjustments take into account the delay time between the time
at which the signals are input to the speakers until the sound is output. This does not
correspond to the actual distance.
• With the automatic adjustments, the average delay time within the speakers’ playable
frequency range is measured. Measurements may not be possible when using special
speakers or in special playback environments. If this is the case, perform the adjustments
manually.
• The AUTO TCR operation cannot be performed if the included microphone is not
connected.
• When performing automatic adjustment, set the head unit to the TUNER mode before
adjusting.
1
Before starting the automatic adjustment procedure, park the vehicle in a
quiet place to avoid the effects of external sounds.
2
Set the vehicle’s key to the ACC position.
Do not start the engine. The vibrations may make it impossible to achieve
the proper adjustment values.
3
Adjust the volume.
Adjust the volume to “-50dB” by performing the volume adjustment opera-
tion on the head unit.
