omar302 Posted January 6, 2020 Report Share Posted January 6, 2020 The ANC is done by the DACMC that is contained within the ANC. The ANC is the CD unit of the infotainment system in the dash. DACMC 2.7L Only The DACMC ANC function only operates while the engine is running, and the luggage compartment lid and all doors are closed. The DACMC is a digital signal processor that consists of an internal analog/digital converter and tone generator. For ANC, the DACMC uses engine rotation speed data, engine torque data, accelerator pedal position data, and ANC microphone input signals to calculate the targeted frequency needed to cancel engine noise within the passenger compartment. The DACMC ANC frequency signals are output by the ACM to the audio DSP module as fluctuating AC voltage. The audio DSP module sends the signal to the LHF door speaker, RHF door speaker, and subwoofer speaker as fluctuating AC voltage. The DACMC is contained within the ACM. The DACMC and ACM require separate PMI procedures when the ACM is replaced. Quote Link to comment Share on other sites More sharing options...
