Patent ID: 7986793

Claim:
An audio system comprising: 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; wherein the first output comprises: a first switch comprising: a first node; a second node; and a third node, wherein the first switch is selectively configurable to couple the first node to either the second node or to the third node, wherein the first node is coupled to the audio speaker, wherein the second node is coupled to the first channel input, and wherein the third node is selectively coupled to the second channel input; and a second output comprising: a second switch comprising: a fourth node; and a fifth node, wherein the second switch is selectively configurable to couple the fourth node to the fifth node or to decouple the fourth node from the fifth node, wherein the second switch is configured to automatically decouple the fourth node from the fifth node upon an external speaker coupling to the second output, wherein the second switch is configured to automatically couple the fourth node to the fifth node upon an external speaker decoupling from the second output, wherein the fourth node is coupled to the third node, and wherein the fifth node is coupled to the second channel input.
