Comparison Pioneer MVH-S520BT vs Pioneer MVH-MS510BT

— Automotive. Traditional car radios designed for use in car interiors, where the device will not be exposed to dust, precipitation and other adverse factors. They have typical mounting dimensions in whole DIN units; the exception is regular models (see below for both).

— Navigation. Radio tape recorders that allow installation on boats, yachts and other types of water transport. They differ from classic automobile models primarily in an increased degree of protection against moisture, temperature extremes and ultraviolet radiation — the cabins of boats and yachts are often made open, and such protection is indispensable. Note that many of these models also allow the use in the traditional way, in cars.

A function that enhances the bass sound. In some way similar to the equalizer, however, unlike it, when using BassBoost, the bass boost is turned on and off with literally one touch of a button — this is more convenient and safer than fiddling with the equalizer settings.

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.
