- 25 - MULTIPLE ZONE AUDIO SYSTEM Abstract of the Disclosure An audio system may be monitored and controlled from one of many remote locations. The audio sources are located at a central location, however, the signals monitored at a remote location may originate from the same or a different source as the signal being monitored at the central location or any other location. The sources are selected and routed to speakers by at least two independent selectors, and the volume is controlled by associated volume controllers, either in the speakers or at the central location. Control of the system is simplified through the use of one or more radio frequency remote controls. Commands issued to the system from a remote control are verified by a verification signal added to the output signal on the appropriate output channels. To alleviate confusion, remote controls retain exclusive control over the source and output they most recently controlled. General function keys on the remote controls are used to control specific functions of the currently selected source, but may map to functions in more than one source.
