The Best Choice of Vehicle Audio and Video Equipment

About car audio and video, the role of the host computer includes tone adjustment, unified coordination of high, medium and low loudness adjustment. For some signals with insufficient loudness, the host computer is responsible for appropriately supplementing the signals with the same frequency range to make them more coordinated. The sound is fuller; Built-in equalization sets different frequency gain supplements for different styles of music. For example, if you press the "ROCK" key on the panel, the host will enhance the bass and treble, highlighting the feeling of rock and roll. There are various classification methods for car audio hosts, and the most common method at present is to classify according to signal sources. The main signal sources of the host are: FM/AM, tape, Bluetooth, CMMB digital TV, MP5, CD, VCD, DVD and MP3, etc. By classifying and combining these sound sources, different types of audio hosts can be produced. The most common one is the three-in-one model of radio, tape and CD, and of course, there are MP3, tape and radio combinations, but that is relatively rare. Car Audio and video are mostly dedicated to special vehicles. Besides playing DVDs, inserting USB flash drives, sd cards, etc., you can also insert navigation cards for path simulation navigation, and there are more entertainment games! I believe that in the future, the mainstream of automobiles will have onboard audio and video!
