ABSTRACT:
A system and method for updating the software of a digital audio amplifier. The digital data used to update the amplifier's software is transmitted as an analog signal over analog audio channels to the amplifier. The amplifier is adapted to recognize when an audio signal should be used to update the amplifier's software, instead of merely driving the speakers with the audio signal. Upon receiving such an audio signal, the amplifier decodes the analog signal into digital instructions. The digital instructions are processed to reconfigure the amplifier's operation.
