FM transmitter - what is it? This unit is a small electronic device that is used to transfer MP3 files recorded on flash media through the FM channel. The emitted signals are played by a standard car radio. The FM transmitter found its main application in cars, where it is an inexpensive replacement for a cassette recorder and digital player.
The power for the FM transmitter is a car cigarette lighter, which is powered by 12 volts DC. As a drive, you can use both USB and SD, MMC cards. The FM transmitter reads files from the drive and recognizes extensions that have a digital audio file format. The number of supported formats is determined by the design of the modulator itself.
The device allows you to organize music files, set their sequence, adjust the volume (power of the emitted signal). On the display of the FM transmitter, we can see the playback file and other information that is attached to the music track. Typically, this unit is equipped with a remote control.
Tuning is done on any wave, free from broadcasting. The car radio tunes to the same frequency. If another radio station is broadcasting in this city at the same height, select any free one. All files that the owner wants to listen to are recorded previously on a personal computer.
The FM transmitter becomes a real salvation for people who like to store large volumes of various music on a USB drive, rather than using discs or hoping that the broadcast will match their tastes. Moreover, you can save a serious amount of money by not having to buy a new and expensive radio with USB support, but just leave the old one. After all, both support radio reception. Therefore, it will be much more reasonable to buy an FM transmitter, which will solve this problem for ridiculous money. Naturally, before choosing, many are faced with some questions that cannot be answered on their own.
