Normal Operation
The audio unit directs the audio signals to the digital signal processing (DSP) module. The DSP module processes the audio signals and sends them to each of the audio amplifiers. The audio amplifiers amplify the signals and send them to the speakers. There is 1 audio amplifier for the left speakers, and 1 for the right speakers. Each speaker has a signal and return circuit.
