The distance between the listener and the speakers in a car vary widely 

due to the complex speaker placement. This difference in the distances 

from the speakers to the listener creates a shift in the sounds image and 

frequency characteristics. This is caused by the time delay between the 

sound reaching the listener's right versus the left ear. To correct this, this 

unit is able to delay the audio signal to the speakers closest to the listener. 

This effectively creates a perception of increased distance for those 

speakers. The listener can be placed at an equal distance between the left 

and right speakers for optimum staging. The adjustment will be made for 

each speaker in 3.4cm steps. 

Listening Position example as follows: 

About Time Correction 

Adjust the time correction level of the front left speaker to a high value 

and the rear right to zero or a low value. 

Example 1: Front Left Seat 

5.1ms

2.25m

0.5m

The sound is not balanced because the distance between the listening 

position and the various speakers is different. The difference in distance 

between the front left speaker and the rear right speaker is 1.75 m (68-

7/8"). Here we calculate the time correction value for the front left 

speaker in the diagram on the above.

In other words, giving the front left speaker a time correction value 

of 5.1 ms makes it seem as if its distance from the listener is the same 

as the distance to the farthest speaker. Time correction eliminates the 

differences in the time required for the sound to reach the listening 

position. 

The time of the front left speaker is corrected by 5.1 ms so that its sound 

reaches the listening position at the same time as the sound of other 

speakers. 

   Conditions: 

Farthest Speaker - listening position : 2.25 m (88-9/16") Front 

left speaker - listening position : 0.5 m (19-11/16") Calculation: 

L = 2.25 m - 0.5 m = 1.75 m (68-7/8") Time correction = 1.75 ÷ 

343

*1

 × 1000 = 5.1 (ms)

*1

Speed of sound: 343 m/s (765 mph) at 20°C

Adjust the time correction level of each speaker to almost the same level. 

Example 2: All Seats 

1

Sit in the listening position (driver' s seat, etc.) and measure 

the distance (in meters) between your head and the various 

speakers.

2

Calculate the difference between the distance correction 

value to the farthest speaker and the other speakers. 

L = (distance to farthest speaker) - (distance to other speakers) These 

values are the time correction values for the different speakers. Setting 

these values to make each sound reach the listening position at the 

same time as the sound of other speakers.
