Audio DSP Module

WARNING: This page is about a different car, the 2014 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The audio DSP module can be operated with the ignition in RUN, ACC, or OFF.

The audio DSP module enhances the input audio signal sound quality from the ACM .

The ACM outputs voltage through the enable circuit to enable the audio DSP module amplifier. When the ACM removes voltage from this circuit, the audio will be muted. When the ACM applies the correct amount of voltage to this circuit, the audio will be unmuted. In the event of an amplifier overload, the audio DSP module reduces audio levels on the left and right audio output channels to prevent clipping and speaker damage.

The audio DSP module receives stereo audio signals from the ACM in the form of fluctuating AC voltage. The audio DSP module processes and amplifies these inputs and sends left and right analog audio signals to the speakers as fluctuating AC voltage.

The audio DSP module receives mono audio signals from the APIM in the form of fluctuating AC voltage. The audio DSP module processes the audio signals and sends them to the speakers as fluctuating AC voltage.

The audio DSP module requires PMI when it is replaced.
