Patent ID: 8422692

Claim:
A speaker control system for distribution of an audio signal to at least one speaker selected from a set of speakers, the system comprising: a set of audio-distribution circuits for distributing the audio signal to the set of speakers; and logic circuitry configured and arranged to receive a signal indicating a selection of the at least one speaker; determine automatically an impedance-based parameter for use in distributing the audio to the at least one selected speaker based at least partly on a load-tolerance parameter for an audio source, volume settings of other speakers in the set of speakers, and on an impedance of the at least one selected speaker, and control distribution of the audio signal to the at least one selected speaker and therein adjust the impedance, at the audio source, of the at least one selected speaker based, at least partly, on the impedance-based parameter, wherein the audio signal is distributed using one or more of the set of audio-distribution circuits.
