Automotive DSP audio processors make up for the many deficiencies of crossovers. DSP, or digital signal processing, is a unique microprocessor, a device that processes a large amount of information with digital signals. For sound, the DSP processor can control the digital signal with a fixed program, and use the strength of the frequency to create a sound field effect.

HiVi PX-406 DSP processor exceeds 16bit, adopts 32bit/96 KHz sampling frequency and 64bit floating-point DSP processor; according to vehicle conditions and user needs, 4-channel audio/video terminals and 6-channel free matrix component configuration output are designed , each channel adopts independent algorithm process control,

The PX-406 has a high and low filter with a slope of up to 48db/0ct to make the crossover more accurate.

PX-406 equalizer parametric equalization digital level can feel the beautification of the sound and the degree of modification of the sound. The equalizer is used to correct the uneven frequency band in order to obtain a relatively flat overall response curve.

The PX-406 up to 31DSP has a unique adjustment system, which can adjust the gain of each frequency at will, so that the sound wave curve in the whole car is smoother, so as to make up for the defects of each speaker and excavate the optimal performance of each speaker.

Whether it is matching, construction or control of every detail, PX-406 effectively solves the difficulty of debugging. When there is a wrong line connection during the installation of the car audio modification line, PX-406 can eliminate this effect through software debugging. At the same time, the PX-406 can convert the signal from one frequency to another, so that the sound of various frequencies can be effectively transmitted to a central position.

PX-406 is a driverless USB connection design, it is easier to connect to the tuning software, and there is no need to install additional USB drivers.

The built-in delay system of the PX-406 allows the entire sound field to be focused and concentrated, and can be tailored to determine the positioning of the sound field. Let the whole car sound form a feeling of a stage: the singer is in the middle, the band is in the back, the whole sound quality, timbre, and reverberation are clearly expressed and true. Let the drivers and passengers feel like they are on the scene, and enjoy the audio-visual "emperor's seat" leisurely.
