Information and Entertainment System - Sony® Sound: DSP
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The Sony® audio system provide theatre quality sound in the vehicle. Audio signals are sent from the ACM to the audio DSP module, which processes the audio signals and sends them to the speakers.
The audio DSP module determines the correct audio environment based on the audio signals it receives and on the network messages it receives from other audio system modules. These messages include such information as fade/balance and speed sensitive volume settings.
The audio DSP module is enabled through software.
In the event of an overload, the audio DSP module clips the audio output signal to the speakers and subwoofer (heard as distortion) in order to prevent damage to the speakers.
