ABSTRACT:
An embodiment of an audio system comprises a speaker system configured to automatically change a coupling of an audio speaker from a first channel input to a second channel input if an external speaker is coupled to a first output. In embodiments of the invention, the speaker that connects to an audio source, such as an audio card of a personal computer (PC), automatically swaps channels based on the jack into which an external speaker is plugged. Thus, the reconfiguration of the audio system is automatic for the user in some embodiments, requiring nothing more from the user than selecting one of two jacks for use with an external speaker.
