Many drivers cannot imagine the process of driving without their favorite music. And automakers fully satisfy this need by installing a multi-channel audio system. The head playback unit of a modern car is able not only to read information from a flash drive, but also to establish a relationship with a smartphone and even recharge it.

But what should the owners of old cars with regular radio tape recorders do? A car FM transmitter with Bluetooth, capable of freely connecting with various gadgets, will help out here.

This is a device that reads audio files in digital format and generates a radio signal of a certain frequency. The generated wave is captured by the antenna of the on-board car audio system, and the desired track is played in radio mode.

The choice of a suitable device is carried out according to the following criteria:

• the allowed capacity of the flash drive
• bluetooth support;
• presence of a microphone;
• radius of action;
• the ability to recharge external devices via USB;
• readable formats of music files.

Choosing the best radio modulator in the budget segment

Initial repeater models only partially extend the functionality of the native audio system. Usually they only recognize a USB stick and a compact microSD. It never comes to a smartphone.

The form factor in the public sector is price. The cost of the devices below does not exceed 500 rubles:

1. Ritmix FMT-A705 - 310 rubles;
2. Rolsen RFA-380 - 330 rubles;
3. Defender RT-Play - 420 rubles;
4. Neoline Droid FM - 450 rubles.

All models are equipped with remote controls and support MP3. In addition, they are trained to save the last song and go through folders with music. The devices mentioned above from Rolsen and Defender are capable of playing WMA along with MP3.

Before setting up the presented FM modulators in the machine, let's figure out the permissible capacity of readable flash media. Models from Rollsen and Neoline only interact with flash drives with a capacity of no more than 16 GB. For competitors, this characteristic is 32 GB.

Analysis of reviews shows that Defender RT-Play is an affordable FM transmitter with good sound quality and the largest range in the segment (10 m, for competitors - 3.5 ... 5 m). However, this product will not be suitable for truckers - like the Rollsen RFA-380, it is powered only from a 12V network. A worthy analogue for heavy truck drivers is Neoline Droid FM with a color LCD display. The Ritmix FMT-A705 is less reliable.

Looking after a car FM transmitter with Bluetooth channel support

The trend is that USB sticks are less and less used as a library for storing your favorite music. This is partly due to the difficulty of matching favorite tracks to suit different moods. But more often than not, consumers refuse this method of transferring music due to the presence of a fancy player or smartphone. And they are known to be equipped with a "blue channel".

Now it becomes clear why budget modulators are rapidly losing popularity among motorists. They have the main drawback - there is no bluetooth.


The cost of a well-equipped repeater with a "blue tooth" is about 2,000 rubles. Fully functional models are:

• Neoline Wave FM - 1,800 rubles;
• Mystery MFM-80BCU - 1,950 rubles.

An interesting alternative to them is the Xiaomi Roidmi 3S. The price tag for this model is 1 150 rubles. We will understand the features further.

For your information. When buying a car FM transmitter with Bluetooth function, you should pay attention to the presence of a microphone. The presence of the latter indicates that the device supports Hands Free technology.

Neoline Wave FM

This gadget is controlled using both hardware buttons and a remote control. On the front panel there are two USB connectors designed for both charging and reading digital information from a USB flash drive. There is also a slot for microSD cards. The maximum removable media capacity is 32GB. Works in both 12V and 24V networks.

The disadvantages of this repeater are:

• a call signal is not transmitted with an incoming call;
• unfinished equalizer;
• lack of broadcasting of RDS tags.

Buying Wave FM, a motorist acquires himself to admirers of the "Hands Free" technology. If the driver does not want to join the ranks of fans of "handless" communication, he will do the analogue - Neoline Rave FM (1,590 rubles).

Mystery MFM-80BCU

Model, like , equipped with an LCD display. The device supports Hands Free and has 2 remote controls included, one of which is attached to the steering wheel. Of the features, it should be noted the presence of the Clear Voice Capture technology, which removes extraneous noise and echo during a telephone conversation.

One of the main disadvantages of the device is the lack of a USB input. Another "minus" is the overly strict requirement for the volume of external microSD. Maps larger than 4 GB cannot be read.

Xiaomi Roidmi 3S

The question of how to set up the FM modulator in the car caused a lot of complaints from the previous 2S model. They were mainly due to the fact that the device did not fit the cigarette lighter of some cars. In the new generation, this drawback is eliminated.

This model is of particular interest among motorists. Close attention is due to the unusual functionality of the transmitter:

• hands Free technology;
• communication with the device through the application in the smartphone;
• the ability to switch tracks by shaking the phone.

Such facts are also remarkable. First, it lacks a display. Secondly, two USB outputs are intended exclusively for charging external devices.

We connect or how to set up an FM modulator in any machine yourself

If a if you just plug it into the cigarette lighter, then with FM transmitters everything looks much more complicated. As you know, the repeater converts the digitized information into a radio signal. It is very important that the frequency of the wave generated by the device does not coincide with the broadcasting frequency of public and special radio stations.

For your information. Frequency 87.5 FM is free in almost any city.

(function (w, d, n, s, t) (w [n] \u003d w [n] ||; w [n] .push (function () (Ya.Context.AdvManager.render ((blockId: "RA -227463-4 ", renderTo:" yandex_rtb_R-A-227463-4 ", horizontalAlign: false, async: true));)); t \u003d d.getElementsByTagName (" script "); s \u003d d.createElement (" script "); s.type \u003d" text / javascript "; s.src \u003d" //an.yandex.ru/system/context.js "; s.async \u003d true; t.parentNode.insertBefore (s, t); )) (this, this.document, "yandexContextAsyncCallbacks");

• • Install the USB stick into the repeater.

• Insert the device into the cigarette lighter.
• Tune the radio frequency using the remote control.
• Turn on the radio and select the Radio mode.
• Tune the audio system to the FM modulator broadcast frequency.

The method of setting up a gadget with bluetooth is almost the same as described above. Only the 6th transition is added, associated with connecting the smartphone wirelessly.

Owners of the Xiaomi Roidmi 3S / 2S car FM transmitter with Bluetooth mode operate according to a different scheme. The device does not come with a remote control - all settings are made in a special application available in Google Play and Apple App Store.

For your information. A blinking LED indicates that the device is not yet connected to the smartphone. After connecting the phone to the repeater via the bluetooth channel, the LED will simply light up.

Setting the operating frequency and activating the track switching mode by shaking the smartphone are made in the application. You can also choose the color of the LED there.

Verdict

• There are two classes of FM modulators: without Bluetooth support (up to 500 rubles) and with support for the "blue channel" (about 2,000 rubles).
• The best repeater without the "blue tooth" module: for a passenger car (12V) - Defender RT-Play; for cargo (24 V) - Neoline Droid FM.
• Decent models with bluetooth: Neoline Wave FM; Mystery MFM-80BCU.
• Xiaomi Roidmi 3S with Bluetooth is an interesting solution: it is controlled by an application installed on a smartphone. The range of functions includes switching songs by shaking the phone.
• The device is configured by selecting the frequency at which the radio tape recorder will receive the radio signal generated by the transmitter. In models with bluetooth, an additional smartphone must be connected to the repeater.

Question which FM transmitter relevant for vehicle owners, whose audio systems do not have the ability to play music files contained on removable digital media. With its help, a standard car radio is able to play music on a USB flash drive or on a mobile phone memory card.

What is a FM transmitter, how it works

Before solving the issue which FM modulator is better, it is important to understand the principle of operation of the device and its functionality. An FM transmitter or frequency modulator is a car device capable of reading and playing audio files from removable media.

Powered by the car's cigarette lighter, the device transmits sound files to the FM receiver installed in the car by radio waves.

It is possible to use a transmitter for a car if three main conditions are met:

• the presence of a standard FM receiver in the equipment of the car;
• equipment of the car with sound speakers;
• location of the cigarette lighter socket next to the FM receiver of the car.

The principle of operation of transmitters for cars is as follows:

• a stream of sound files read by the transmitter from an external digital carrier,
• sent to the modulator (transmitter) of the device;
• the transmitter transmitter transmits audio files to the FM receiver of the car, broadcasting through the speakers.

Depending on the model of the transmitter for the car, external media used to read sound files can be:

• regular flash drives;
• sD memory cards;
• flash drives such as microSD.

Modern models of car transmitters can play audio files of various formats, namely:

• MP3;
• WAV;
• WMA;
• FLAC.

The most popular format is MP3 (MP3). Files of this type can be read by any model.
To ensure the connection of the vehicle transmitter with an external storage device, three communication elements are provided in its design:

• USB port... Through it, a USB flash drive, an iPhone or another smartphone, an iPod and other digital players can be connected to the transmitter for a car.
• Memory card slots of various types.
• Bluetooth (bluetooth) a module used to transfer sound files from a phone or MP3 player.

Advantages and disadvantages

Like any technical device, FM transmitters for a car have both pros and cons.

• no need to re-equip the entire car audio system;
• selection of the file of interest from the playlist;
• the ability to customize the playback sequence;
• rich functionality of most modern models of FM transmitters.

• low sound quality;
• the inability to use in places where the passage of radio waves is limited or completely absent (tunnels, mountain gorges, etc.).

Car FM transmitter with Bluetooth

Car FM transmitter, offered today by many manufacturers of such gadgets, is a modulator that differs from conventional models in impressive functionality. It works with a flash drive from a car cigarette lighter, has the ability to pair with a mobile phone via a wireless channel.

Using a similar transmitter installed in the car interior, you can organize a speakerphone when talking on the phone, which is convenient when driving.

MP3 player with FM modulator

Automotive offered by many manufacturers MP3 player with FM transmitter - a conventional FM receiver with convenient control and control panel. The set additionally contains a display that displays information about the sound files being played. Using the FM transmitter functionality for a car of this type, you can perform the following actions:

• select the sound files of interest;
• arrange the selected audio tracks in the desired order;

How to set up a FM modulator in a car?

Knowing how a car transmitter works, it is not difficult to configure this device for its full functioning. Before you start using the gadget, we recommend downloading the mobile application to your smartphone and combining the frequency of its transmitter with the frequency of a standard car radio.

What to do if the device does not read the USB flash drive?

If the car FM transmitter does not see the USB flash drive, then there are several reasons for this situation:

• the flash drive is not formatted and contains hidden files or sound files in the wrong extension in its memory;

• faulty flash drive, which can be easily checked on any PC or laptop.

I'll tell you about an FM transmitter with Bluetooth for a car.

I think the owners of not new cars at least once in their life had a question with MP3 music. Usually, native audio systems only support audio CDs, CDs with recorded mp3 files can of course be supported by some (I don’t presume to say for sure - I didn’t have a lot of cars in my life), but unfortunately I don’t have such a function, while I have Bluetooth - but it can only be used for calls, it does not play music.

FM transmitter (modulator) is a budget solution to this problem. What what, but a radio and a socket are in every car.

This model also has bluetooth - very convenient for those who do not have bluetooth in their car at all, especially since now they are fined for driving while talking on the phone (Kazakhstan).

Declared technical characteristics

It was packed well, everything came intact in about 20 days. The kit looks like this:

The set includes the transmitter itself, AUX cord, instructions on "Chinglish".

The device itself looks like this:


On the front face there are 2 buttons - green for answering a call and Play / Pause, red for ending / canceling a call and entering the frequency setting mode.

On the left side there is a rocker "±", an On / Off switch, an On / Off indicator, an AUX input.

As you can see, there is USB and OUT 2A

My video review with unpacking (at the discretion of the site administration):

I made a mistake in the video saying that it costs $ 8 instead of $ 12!

To connect: plug the modulator into an outlet, tune to one frequency and go!

Songs are switched by pressing "±" and this is not very convenient, the buttons are very small. Rebinding the keys is not possible. This only applies to listening to music via USB. Through AUX and Bluetooth, all control from your mobile device.

Also noticed that the best quality via AUX, USB has noise at high volume (this is a problem with many modulators); music via Bluetooth also does not spoil with quality (version 2.0).

As a result, we have: a functional FM transmitter for an adequate price, not without drawbacks, of course.

Pros:
AUX, Bluetooth (with music playback), smartly works with a USB flash drive (does not "tupit")

Minuses:
Interference (noise) at high volume (I tested only in my car, maybe something is wrong with me), a very inconvenient song switch.

An FM transmitter or FM modulator (Frequency modulation) is an additional vehicle device designed to play digital audio files recorded on a flash drive using an FM car radio.

The device was very common ten to fifteen years ago, when not all car radios were equipped with USB inputs. After connecting an additional FM transmitter, the radio tape recorder acquired a very useful option - the ability to play digital audio files. In most cases, this is more convenient than playing CDs.

Modern FM transmitter devices are supplemented with smartphone pairing functions. Thus, if your car is equipped with an old-style head unit that does not allow reading audio information from smartphones, other digital media, you can, without resorting to great costs, significantly expand the functionality of the audio system using an FM transmitter.

The device and principle of operation of the car FM transmitter

The FM transmitter is usually designed as a separate electronic unit with a plug for connecting to the car cigarette lighter socket. For the convenience of adjusting the location of the controls and controls of the FM transmitter, the electronic unit is often attached to the movable hinges of the connector. Some transmitter models have a remote control.

Transmitters can use USB flash drive or SD memory (microCD) as a source of information. Newer models of FM transmitters have an interface for connecting smartphones.

When purchasing an FM transmitter, pay attention to the system requirements for the file system and the maximum memory capacity of the USB stick. If the requirements are "no more than 1 GB, FAT16 system", then the information on a USB-drive with a capacity of 2 GB or formatted in FAT32 will not be read.

The digital part of the transmitter reads audio files from a flash device or a smartphone (in WAV / WMA / MP3 / FLAC and others in accordance with the parameters specified in the technical specifications), converts from a digital to an analog (continuous) signal that goes to the frequency modulator (FM ).

A low-power FM modulator transfers the signal to the carrier frequency of the FM radio signal. This carrier frequency must not coincide with the broadcasting frequency of public and special radio stations, otherwise there will be an overlap of radio waves.

An FM radio installed in the car is tuned to the carrier frequency of the transmitter. It plays digital audio files in the sequence specified by the FM transmitter control system.

Types of car FM transmitters and which one is better to choose

Conventionally, car FM transmitters can be classified into three categories:

1. Simple ones with little functionality and a black and white display

They have a low cost, a minimum number of controls and functions. Designed to work together with inexpensive car audio systems. Provides average playback quality.

These lower priced FM transmitters support small flash memory capacity. In many cases, it is not possible to fully scan the entire playlist. It is advisable to write audio files for playback by such a transmitter to the root directory... They have no memory of their own.

For example, the Ritmix FMT-A705 FM transmitter, which costs about 400 rubles, has a remote control, a built-in display, can play MP3 audio files from SD media, the range is 5 meters.

2. Medium price category

Usually equipped with color displays that are capable of displaying photographs and other graphic information from media. They have advanced functionality, the ability to read information with a complex hierarchy of the file system on large media. They have built-in memory, which significantly increases the speed of information processing, allows you to play audio files in various formats.

For example, the Ritmix FMT-A765 FM transmitter with a color display, which costs about 600 rubles, plays MP3 and WMA files, is completed with an audio cable for connecting to the phone jacks and other media players 3.5mm / 3.5mm, supports SD memory slots up to 16 GB, and is completed with a remote control remote control.

3. FM transmitters for cars with Bluetooth

A feature of these devices is the ability to pair with smartphones wirelessly. With the help of such transmitters, you can organize a speakerphone when talking on the phone.

FM transmitters with Bluetooth have advanced functionality.

For example, the Jet.A JA-16 car FM modulator with built-in 2Gb memory, linear input-output, USB slot, remote control, video and photo playback can be purchased at a price of 1000 rubles. Equipped with Bluetooth interface.

Selection features

When choosing a model for an FM modulator, one should proceed from the intended modes of its operation.

If you only use the car radio as a source of background sound in your car, you can limit yourself to the simplest models with a remote control.

If you are a professional driver, or you constantly use a car at work, it is better to purchase a more expensive model with Bluetooth connectivity. It will make pairing with a smartphone much easier.

For audiophiles who are critical of sound quality, more sophisticated device models equipped with color displays capable of reproducing audio information of any format are suitable.

How to set up a modulator in a car so as not to hiss

Most common problem when installing FM — modulator - hiss when playing audio files.

In most cases, this occurs due to an insufficient level of the radio signal at the input of the car radio. Most transmitters have a range of more than 5 meters, and the radio is within 10 to 50 centimeters from the cigarette lighter socket.

In fact, the radio signal from the transmitter is picked up by the antenna of the car radio, which can be located outside the passenger compartment, sometimes in the rear of the body. In addition, the signal is attenuated by the shielding properties of the metal surfaces of the body. The presence of electromagnetic interference in harsh urban environments further obscures the FM modulator signal. Perhaps the spectrum of broadcasting stations is superimposed on the signal.

If the car radio has an active antenna located on the windshield, the signal from the transmitter may be too strong and cause distortion in the input broadband antenna amplifier.

What to do if the signal from the FM transmitter is accompanied by hiss:

• try to rebuild the transmitter (and the radio receiver, respectively) to a different frequency;
• change the location of the radio antenna:
• disconnect the active antenna of the radio or install it away from the transmitter;
• if your locality does not receive FM radio stations or you do not listen to them, you can turn off the external antenna altogether.

If the FM transmitter stops working and does not show any indicator lights or display messages, you can try to disassemble it.

There must be a fuse inside the case. Perhaps it has burned out, then it should be changed. You can clean the main board, sometimes it helps.

• do not put the remote control and transmitter under the windshield during the warm season, if exposed to direct sunlight, the temperature in this place may rise above 100 degrees Celsius;
• many transmitters, especially those made in China, have unreliable connectors, if you constantly remove and insert the transmitter into the cigarette lighter, they fail, it is better to do this using a connector splitter;
• like any electronic device, the transmitter should be stored in a package or bag to prevent moisture and dust from getting in, "felting in the glove compartment" is not the best way to store it.

It may be useful for you, especially if you are going to rent a trailer for long distance travel.
