THX® Sound
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
For vehicles with the THX® sound system, the audio DSP module provides 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 all of the speakers. An enable/clip detection circuit is utilized for the amplifier (internal to the audio DSP module). The circuit carries out 2 functions: to turn the amplifier on, and to indicate when the speaker output distortion signal reaches a damaging level. The audio DSP module communicates on the MS-CAN . Customer preference settings such as fade and balance are broadcast to the audio DSP module by the ACM .
