Abstract
A signal processor for use in a vehicle audio system provides multiple operating modes. A first mode provides substantially equal total sound pressure levels at each seating location. A first equalization pattern provides a substantially similar frequency response at each of the seating locations, and a first balance configuration provides substantially similar balance patterns at each of the seating locations. A second mode provides greater sound pressure levels at a first seating location than at other seating locations. A second equalization pattern results in a frequency response at the first seating location that is substantially smoother than the frequency responses at other seating locations, and a second balance configuration results in the balance pattern at the first seating location being substantially more balanced than the balance patterns at other seating locations.
