A Blaupunkt innovation: DSA, the acoustic centre
The acoustic centre. Surrounded by uniform sound from all sides and right in the centre of it all - Blaupunkt takes it into the car. The fact that the driver doesn't notice a thing tells him how perfectly the system is working. The digital signal processor of the DSA system uses a microphone to measure the acoustic frequency response in the vehicle interior and operates an electronic 9-band synchronised equalizer that regulates all four channels separately.
