This invention relates to a self-diagnostic audio system including a digital signal processor (DSP) that monitors a plurality of electronic components in an audio system, such as an amplifier, speaker, memory, power supply, and DSP itself. The DSP may monitor various information from each of the electrical components, such as whether a particular electrical component is on or off, whether a particular component is functional, and whether the voltage current is between the components. The DSP may be linked to a reporting device so that if there is a problem, the DSP may report back and identify the existence and nature of a particular problem.
