Short body
Tape recorders with a
shortened body.
In this case, shortened means a case that has a shallower depth than classic radio tape recorders equipped with CD drives. Due to this, such models are quite compact, which, in particular, simplifies installation and facilitates wiring. Of course, CD / DVD discs are not supported in principle by such radio tape recorders, but this is not a serious drawback — nowadays there are quite enough alternatives to such media. Also note that the shortened layout does not affect the mounting size (see above) — it can be 1 DIN or 2 DIN, and standard solutions are even larger.
DSP
The presence in the radio built-in
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.
Volume control
The type of volume control provided in the radio.
Rotary knobs,
sensors or
mechanical buttons are most often used in this role; Here is a more detailed description of each of these options.
— Rotary regulator. The traditional regulator in the form of a round knob, which does not lose popularity nowadays — in fact, it is he who is installed in most modern car radios. Such prevalence, among other things, is due to the fact that the rotary knob is compatible with both digital and analogue volume control circuits — which means that it can be used in devices of any level, from top-end to the most simple and inexpensive. In addition, such a regulator stands out noticeably on the radio panel, so you can even find and turn it by touch, without being distracted once again from the road. The disadvantages of rotary knobs include perhaps some bulkiness compared to buttons and sensors, but this moment is extremely rarely significant.
— Mechanical buttons. Traditional mechanical buttons — more precisely, most often one double-sided rocker button, vertical or horizontal. Unlike the rotary knobs described above, they can only be used with digital volume control circuits; therefore, most radio tape recorders with buttons are advanced devices with extensive functionality and a size of at least 2DIN (or a screen of at least 5 ", for standard models). In such cases, the advant
...age of buttons over rotary controls is that the rocker can be made very narrow and install even on a very thin screen frame, while the handle requires a fairly wide additional panel. And if you compare this option with sensors, then mechanical buttons are somewhat cheaper, and you can control them blindly without taking your eyes off the road to the radio panel. On the other hand, the mechanics tend to wear out with use, making it less reliable, and many users simply don't like buttons more than sensors, and for these reasons, and a few others, this option is relatively rare.
— Touch buttons. Controls in the form of sensors that are triggered not by pressing, but by touch. Like mechanical buttons (see above), this control is only compatible with digital volume control and is mainly used in advanced radios with large screens. At the same time, the sensors give the device the most advanced and “technological” appearance, attractive to many users from a purely aesthetic side. The main disadvantage of this option is that the touch buttons usually do not protrude from the panel — so it is almost impossible to find the right sensor blindly, and when controlling the radio, you inevitably have to be distracted from the road. However, with more or less decent driving skills and due care, this moment is not a serious drawback, so this type of control in high-end radio tape recorders is used much more often than traditional buttons.AUX
Standard input for analogue audio transmission. The presence of such a connector allows you to connect an external sound source (for example, an audio player) to the radio to play music through the car's acoustics. The specific connector type used in such an input may vary. The same goes for its location; AUX on the front panel is most convenient, this feature is indicated separately in our catalog (see below).
