Abstract:
1. An audio control system for managing a plurality of audio source devices, the system comprising: a plurality of audio input signals, at least one of the audio input signals corresponding to a priority audio source device; a gain adjustment circuit that receives at least one of the audio input signals and is configured to adjust gain for the at least one audio input signal received; a switching circuit configured to select one of the plurality of audio input signals and switch the selected signal from the respective audio source devices through the switching circuit, wherein the switching circuit further comprises a right channel multiplexer and a left channel multiplexer in communication with a volume processor, the volume processor receives a right channel audio output signal from the right channel multiplexer and a left channel audio output signal from the left channel multiplexer; a controller in communication with the switching circuit to control switching of the switching circuit and in communication with the gain adjustment circuit to selectively establish an input level for at least one of the audio input signals; a signal detector in communication with at least one of the audio input signals and configured to detect presence of a signal from the priority audio source device; the controller directing the switching circuit to deselect an existing input and select an audio input signal corresponding to the priority audio source device when the signal from the priority audio source device is detected; and a display module having an associated input control, the controller in communication with the display module and input control to provide reprogramming of priority levels associated with the audio input signals via user selection of the input control associated with the display module, wherein the plurality of audio input signals include a telephone audio signal transmitted from a cellular telephone and a navigation audio signal transmitted from a navigation system; wherein the switching circuit further includes a summing circuit for summing the telephone audio signal and the navigation audio signal to generate a summed signal that permits a user to receive first data on the telephone audio signal and second data on the navigation audio signal, and wherein the controller is configured to interrupt at least one first audio source device that transmits a first audio input signal and to prevent transmission of the first audio input signal if the first audio input signal does not correspond to one of the telephone audio signal and the navigation audio signal for enabling the user to receive the first data on the telephone audio signal and the second data on the navigation audio signal without interruption from the first audio input signal.
