The audio DSP module enhances the input audio signal sound quality from the ACM.
Audio signals received by the audio DSP module are sent to the audio system speakers as fluctuating AC voltage.
The audio DSP module receives audio signals from the ACM in the form of fluctuating AC voltage. The audio DSP module processes these inputs and sends left and right analog audio signals to the speakers as fluctuating AC voltage.
The audio DSP module requires PMI when it is replaced.
