It synchronizes the arrival of sound from various speakers to create a coherent sound field, effectively placing the listener at the center of the music.
In a standard car setup, the left speaker is much closer to the driver than the right speaker. This means the sound from the left arrives at your ears milliseconds before the sound from the right, creating a "heavy left" soundstage. The Sound Manager allows you to adjust the "listening position," delaying the signal to the closer speakers so that sound from all speakers hits your ears simultaneously. This creates a centered, phantom center channel right in front of the steering wheel. alpine imprint sound manager 21
