Digital Signal Processor
The top "Hi Fi" option has a digital signal processor (DSP) amplifier which is located in the left hand side of the luggage compartment. It drives two speakers in each of the rear doors, three speakers in each of the front doors, a center speaker connected across the two front mid-range speakers and two dual voice-coil subwoofers in the luggage compartment. It can also use digital signal processing techniques to simulate a Concert Hall, a Jazz Club, a Cathedral or one of three user defined settings. These functions are controlled from the Multi-Function Display via the DSP option.
