Time Alignment Adjustment <T.A.> (Open state)

In the vehicle, the different speaker units are at widely differing distances from the listener. The sounds from the speakers therefore reach the listener at different times. When a multi-amp system is set up, this causes different delays for each frequency band (high, mid, low and ultrabass-ranges), marring the position of the sound image and the overall balance and disturbing the frequency characteristics.

The Time Alignment Adjustment function is able to synchronize the arrival times of the different sounds by delaying the output of signals from the closest speaker units.

Switching to the Time Alignment Adjustment Mode

1.Open the cover of the remote controller in the Network Menu (refer to page 5).

This switches to Network Menu Setting Screen.

2.Press the FUNCTION button 2.

The display switches to Time Alignment Adjustment Screen, allowing time alignment adjustment.

Measuring the Distance to be Corrected (Delay Time)

It is necessary to calculate the delay time to correct the time differences between speaker units. In order to adjust the Time Alignment Adjustment function more easily, this System allows the delay time to be set up by simply inputting the difference in the distance between speaker units (the distance to be corrected). (The delay time will be automatically calculated by this system.)

Although the distance from each speaker unit varies depending on the position of the listener, the first set up is made for the driver’s seat. If the set up has been made for the driver’s seat, the optimum delay time for the listener’s position can be set up by simply switching the Position Selector function (refer to page 17) to the listening position. (This System automatically calculates and sets up the optimum delay time for each position.)
