ABSTRACT:
An automotive audio system separates audio signals from an audio signal source into first and second components. The first component of the audio signal is sent directly to a first main amplifier and reproduced through a main speaker or speakers. On the other hand, the second component of the audio signal is sent to a second main amplifier after a predetermined delay time determined by a delay circuit. The delayed second component of the audio signal is reproduced through a auxiliary speaker or speakers after the predetermined delay time. The first and auxiliary speakers are distinct and preferably located at different points in the vehicle compartment. As a result, the directly reproduced first component and the delayed second component are reproduced through different audio sound sources. This affords the listener higher-quality audio sound and better ambience. If necessary, an echo signal generator may be added to the second component reproduction system to provide an echo effect. In this case, since the second component is reproduced by the second speaker or speakers which are different from the main speaker or speakers which reproduce the direct first component, the echo effect can be optimized for good ambience.
