FM transmitter is a device that helps to read music files from media such as a USB flash drive, SD or MMC card, player or even an external hard drive. The device broadcasts playable files at the selected radio frequency, to which you can tune the car radio or any other gadget with an FM receiver.
Instructions
Step 1
The transmitter is connected to the cigarette lighter in the car. Due to voltage surges, many modulators burn out, since the voltage arrives unevenly, especially in domestic cars. Therefore, the main characteristic of the transmitter should be its reliability and the presence of a fuse, which you can always replace in the event of a breakdown.
Step 2
Decide on the price. The lower the cost of the device, the smaller the range of reproducible frequencies. More expensive models allow the user to manually set the desired frequency. Some transmitters only have a fixed bandwidth and only support playback on one frequency.
Step 3
Pay attention to the presence of a remote control in the delivery set, which allows you to switch melodies, adjust the sound and broadcast frequency from a distance. The remote control is a small panel and can be bundled with both budget models and the most expensive multifunctional devices.
Step 4
Pay attention to the presence of a display on the device. The highest quality models are equipped with an LCD screen that displays a sufficient amount of information, namely the transmitting frequency, song number and name, indicator of the connected device. It is desirable that the display has a backlight, since this will greatly simplify the control of music while driving and at night. There are modulators with built-in equalizer.
Step 5
Of the additional functions, it is worth noting the ability to adjust the position of the body relative to the driver or passenger. Due to the inconvenient location of the cigarette lighter socket, inconvenience in driving or when shifting the gearbox may arise. The most expensive models are usually equipped with a hinge that allows you to rotate the device panel to the most convenient angle. Before purchasing a transmitter, make sure that the device can be adjusted and securely locked in a comfortable position.
Step 6
Some transmitters are equipped with the function of playing from SD and MMC cards. Most modulators have built-in memory and often enough to load a couple of hundred musical compositions.
