Abstract:
1. A sound processor for use in a vehicle audio sound processing system, the sound processor comprising: a crossbar mixer configured to form a first real audio output signal that is useable to produce sound in a first sound zone, the crossbar mixer also configured to form a second real audio output signal that is useable to produce sound in a second sound zone; and a zone control that is adjustable to control the signal strength of each of the first and second real audio output signals in the respective sound zones; where the crossbar mixer is configured to include a predetermined frequency range of the first real audio output signal with the second real audio output signal so that when the zone control is adjusted to minimize the signal strength of only the second real audio output signal, the predetermined frequency range of the first real audio output signal is available to produce sound in the second sound zone.
