The size of the car radio in width and height, which determines the possibility of its installation in a car. For successful installation of the radio, it is necessary that the corresponding socket in the car has the same size as the radio itself, or more.
The universal unit for measuring the mounting dimension is DIN: 1 DIN corresponds to a width of 178 mm and a height of 50 mm. At the same time, devices of different sizes have the same width and differ only in height:
-
1 DIN. The most common standard size of modern car radios (see dimensions above).
-
2 DIN. This standard size corresponds to a radio height of 100 mm and a width of 178 mm. Typically, 2 DIN sizes are quite powerful devices with a lot of additional features - for example, they are often equipped with large color screens, suitable even for watching videos.
A separate variety are the so-called.
standard recorders. These are devices originally made for a certain brand of car and, as a rule, supplied immediately with them in one of the configurations. Such radios have their own unique mounting dimensions, often not related to the DIN standard, as a result of which they cannot be installed in any car models other than tech for which they were originally intended. In addition, the installation and dismantling of standard radios, as a rule, is much more difficult than that of uni

DSP — digital sound processor.
Such a processor improves the overall sound quality and provides additional options for its adjustment. One of the most important DSP functions is time correction: it allows you to adjust the acoustics so that the sound from speakers located at different distances from the user reaches it at the same time. Such coordination significantly improves the impression of the sound. In addition, radios with DSP necessarily have a digital crossover (frequency separation) and an equalizer with a fairly large number of bands.
The presence of a processor significantly affects the price of the radio, but in most cases this is a justified payment for the sound quality. But the unequivocal disadvantage of "processor" models is the difficulty in installation and configuration, for this it is best to contact a specialist.
The function of accelerated charging of external devices - for example, smartphones - from the USB port of the radio. The general principle of this procedure is that increased power is supplied to the gadget; but its specific features may be different. For example, some models provide a separate USB port intended only for fast charging, while others use the same connector to which flash drives are connected. In addition, the radio may support special
fast charging technologies; they speed up the process even more, but only work with compatible devices; for other gadgets, accelerated charging may not be available at all. It doesn’t hurt to clarify all these nuances before purchasing.
