Comparison Pioneer SPH-DA160DAB vs Pioneer SPH-DA130DAB

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.

Diagonal display size of car radio. The larger the screen, the larger the image on it and the better, usually, information is perceived; in addition, large size is important if the screen is touch-sensitive (see Touch screen). On the other hand, in car radios, the display size is limited by mounting dimensions and almost never exceeds seven inches.

The number of line outputs (see above) provided in the design of the radio. It should be noted that usually these outputs use RCA connectors (“tulip”), and the analog format allows only one audio channel to be transmitted through one such. Therefore, to work with a stereo signal, two RCA connectors are required, and just a pair of such jacks is considered to be one line output - a set designed for one set of stereo speakers. The main difference between this interface and the same RCA used to connect speakers (see above) is that the line output receives a signal from a preamplifier that is unsuitable for feeding to passive acoustics. Such a signal must be sent to active speakers or an external amplifier (whereas the speaker is connected to the output of a power amplifier designed for passive speakers).

The number of composite video inputs provided in the design of the radio.

Composite video input is usually an RCA connector ("tulip") of a characteristic yellow color. It can be used to connect any video source with an appropriate output, such as a portable DVD player. Note that in this case, only the input intended for working with video is meant; to output sound, you will have to use another interface, for example, a linear one (see above). The image quality when connected via a composite connector is relatively low, HD resolutions are not supported, but this can hardly be called a serious drawback, given the characteristics of displays in modern radios (and separately made car TVs / monitors, which can broadcast a signal from the radio).

The more composite video inputs provided in the radio, the more signal sources can be connected to it simultaneously.
