About Time Correction

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 examples as follows:
