Wireless microphone: how it works, how to use, review of the best

The operating principle of a wireless microphone is based on transmitting an audio signal using a radio channel. This eliminates the need for a connecting cable between the voice device and the low-frequency amplifier. The micro housing contains a low-power transmitter. Its high-frequency signal is modulated by audio frequency and transmitted over a distance. A demodulator receiver is connected to the ULF input. It extracts audio frequency voltage from the total signal and supplies it to the input of the amplifier. This is how professional wireless devices work. They are used in television shows and by performers working on the professional stage.

Why do you need a microphone for a smartphone?

There are special built-in gadgets. The user can actually buy one for himself and simply get rid of the constant settings, which later need to be edited due to a bad device. Modern smartphones rarely actually have a high-quality microphone. Most often, devices are equipped with a very good camera, you can even download a semi-professional one. But they are simply lost against the background of the fact that the sound recording sags greatly.

To record high-quality sound on video, save the moment and not constantly adjust the microphone and sound on your phone, you simply need a high-quality microphone, which can now be purchased as an additional one.

Such devices will be of great help to people such as:

• Journalists;
• Musicians;
• Students, because there is often a need to record a lecture;
• Bloggers.

All these people simply cannot live without devices that produce high-quality sound. For example, for journalists, it may be necessary to conduct some kind of interview at any time. It’s clear that he won’t always carry a high-quality camera or a large voice recorder, but a small, high-quality built-in microphone is what he really needs.

Musicians can record their creativity directly on their phone. You don't have to go to a recording studio for these purposes. You can always use your own microphone. It saves money.

In general, it is worth noting that the built-in microphone is a very useful invention that will help many users forget about bad sound on video. A high-quality device will help to completely suppress any noise, sounds and other interference that will not need to be adjusted later in the settings.

What problems may arise when connecting?

As a rule, having decided to use the karaoke function on their Smart TV, users make the connection themselves. But this cannot always be done successfully. The following problems may occur when connecting a microphone:

• the equipment does not connect or is not recognized by the TV panel;
• detection and settings are completed, but I can’t sing karaoke because there is no sound.

The main question is how to install karaoke on your TV correctly. To solve these problems, try to restart all the equipment first, if the problem persists, update the software. Perhaps the signal is weak and cannot be detected between devices, so you need to buy a signal amplifier. Check if your device is compatible with the TV model. Lack of connection occurs very often for this very reason. The device can be replaced by cameras adapted for connection to a TV panel.

If there is no sound when connecting, and restarting the devices does not help, then you will have to call a setup wizard or replace the device in a store. Before purchasing, be sure to check the functionality of all devices at the registration stage.

The karaoke player function may not work correctly due to differences in the input impedance of the devices. You can solve the problem by purchasing an amplifier through which the microphone is connected. If the device is wireless, make sure that the battery charge level is working.

What is a Bluetooth microphone for karaoke?

In simple terms, a wireless karaoke microphone is a device that already has a speaker built into it. That is, it is a full-fledged device that is completely ready for use.

No additional acoustics are required here. It independently reproduces the voice signal received by it in real time. It also has its own settings. This:

• Adjusting the volume of music and voice.
• Bass adjustment.
• Full equalizer.
• Terrestrial radio.
• Ability to switch playing tracks.
• Voice improvement.

How karaoke works

Before connecting a microphone to the TV, it is advisable to familiarize yourself with how this system works:

• first, the television panel begins to play music and show words on the screen;
• To enhance the sound, it is imperative to connect speakers;
• A countdown will appear on the screen before the singing begins. This is practical if the composition is unfamiliar.

The most common method of arranging a karaoke microphone for a TV is a DVD system. It is arranged in the following way:

1. The DVD playback media is connected to the television panel.
2. Install a flash drive or disk with content.
3. To look at the lyrics, you need a screen. For example, this is the LG home screen LCD.
4. You will need a suitable microphone model, preferably one with radio control. It is recommended to use speakers to amplify the sound.

How does a wireless microphone work?

Data transfer from this device is carried out as with any other wireless accessories. For this purpose, radio waves or infrared rays are used. Radio waves are more popular because they have a fairly large coverage radius and various obstacles do not interfere with them. The operating principle itself is very simple. The audio signal received by the microphone is transmitted to a special sensor. This sensor converts incoming sound into radio waves. After which the radio signal is sent to the receiver, which outputs the sound to the speakers. If a manual version is used, the radio wave source will be mounted inside. If the microphone is wired, then it is equipped with a special unit that is attached to the belt. Whichever of these two wireless microphone options you use, they both come with an antenna. The antenna can be built into the device, or external. To ensure operation, microphones use batteries, these can be either batteries or rechargeable batteries.

The practical applications of a radio microphone are truly diverse.

1. In the author’s version, the radio microphone showed good results as a listening device. Moreover, any portable transceiver or all-band receiver, for example, Kenwood TH-F7 (photo 2), tuned to the frequency of the radio microphone (in this case, to the frequency of 98.1 MHz) can receive the radio signal from this microphone. Considering the low cost of a radio microphone, in some cases you don’t even need to assemble its circuit yourself. All you have to do is disassemble the microphone and carefully move its “filling” into another, more compact case the size of, for example, a matchbox.

Photo 2. Portable transceiver Kenwood TH-F7

2. Anti-bug device. In the vicinity of the radio microphone, all other transmitters (even powerful FM radio stations, if they operated on this frequency) are blocked. There is a faint rustle on the air from a working radio microphone generator. Thus, if someone’s bug is operating at a frequency of 98.1 MHz, then by turning on the radio microphone, you can block the listening device.

3. In the future, the carrier frequency of the master oscillator of the radio microphone can be adjusted to another one in order to combine it with the frequency of the “bug” and thus neutralize it.

The electrical circuit of the device and the operating principle of the MIC-140 radio microphone are presented to national experts to understand the principle of its operation, and will undoubtedly be useful in the event of upgrading the device or repairing it.

Connecting the microphone

There is no particular difference in whether the device is connected to a personal computer or to karaoke. To get started you need:

• Take it out of the package.
• Connect it to the power cable.
• Fully charge the device.
• When the device is charged, you need to turn on the power button on the case.
• The product is ready for use.

Then you need to ensure that the microphone and other components are properly connected.

On Windows 7 and 8 operating systems, the connection is as follows:

• In the lower right corner of the screen, right-click the volume menu icon.

• In the menu that opens, you need to find the “Recording devices” item.
• A list of all devices appears. You need to find the right microphone.
• You need to double-click on the microphone icon, after which the “Device Application” window will open. You must set the value to “Use as default”.
• Then you need to click “Apply” and “Ok”.

REFERENCE. Before you start connecting, you need to check whether your laptop or computer supports this function.

To enable wireless mode on the microphone, you need to:

• Turn on the device. A special indicator light should light up, indicating that BlueTooth is ready for use.
• On the receiving device, you need to find “BlueTooth Search” and use it to detect the microphone. Then make the connection.

REFERENCE. Sometimes the device may ask you to enter a password. As a rule, the manufacturer sets the default value to 0000.

• Next, you need to enable the required audio file on the external device.
• Make the required volume, bass and treble settings.
• You can enjoy singing.

Do not forget that all products are intended for different purposes. There are ordinary ones, and there are also professional ones. The second option provides better sound. You also need to pay attention to the time the device operates without recharging or replacing batteries.

If the microphone is of high quality, and all settings and connections are made correctly, then you can enjoy karaoke at home or practice professional singing without any problems.

Criterias of choice

Choosing a portable karaoke microphone with speakers is not an easy task. An incorrectly selected model will certainly ruin your mood, especially if it is a gift for a loved one.

Before purchasing a device, it is necessary to thoroughly check its characteristics and technical capabilities.

The microphone must clearly and clearly convey the voice of the examiner. In this case, you cannot turn on musical accompaniment. Unwanted sound waves during testing can distort the result, adding echoes, rustling and clattering to the words

These effects are additional options that can be activated at any time. It is important to check the documents on the number of hours of uninterrupted operation, and immediately determine how much time the future owner of the microphone will be able to devote to singing. For some, 3 hours is enough, for others, models with 8-hour potential are more suitable. Some people focus on charging the microphone. Although in fact this is not a primary requirement for quality, yet consumers opt for microphones with high charging speeds. It is extremely important for every person to purchase a device with a unique design.

Microphones in this matter differ in color, handle length, head design features and the shape of the control unit.

What types of external microphones are there?

External microphones are also divided into several large categories, namely 3:

• Lapel;
• Guns;
• Stereo (these are more suitable for creative individuals, including musicians).

It is worth considering each in more detail.

Lavalier

Lavalier devices attach perfectly to any clothing. They differ in small dimensions. Lavaliers serve to record a person's voice, so this type is great for bloggers and journalists who constantly need to regulate such an object as excellent voice quality.

As a rule, such microphones have one main drawback - non-directionality, that is, extraneous noise is clearly audible when recording from such a device. In addition, lavaliers are not suitable for recording musical compositions, since their frequency range is limited.

Guns

The second type is cannons. They were called that because they are directed in one direction, that is, they cover the minus of the loops and do not create noise in the background. Recording from such microphones takes place ahead of the user, that is, it is necessary to constantly monitor the process so that the voice clearly enters the microphone. If you hold the sound directly away from the source, then when recording music you can find that the voice is suppressed, that is, the device has removed extraneous noise.

Guns are not suitable for recording songs, that's why they are directed. It is impossible to create a full sound with such a device. But for those who want to achieve a clear voice when recording an interview or video, this is the best option.

Stereo

The last type is stereo. Stereo devices are ideal for musicians, because they not only capture sound throughout the entire room, but also play it out beautifully and make it voluminous. It is worth noting that many models may have a high price, but this is far from true. You can buy them in different price categories, but the sound quality may be poor.

Microphones can also be wired or wireless, but this classification does not stand out as the main one. The difference is the connection method. Wireless devices are synchronized with Android using simple Internet or Bluetooth, while wired ones must be connected through special wires.

What are the tricks and nuances when using a lavalier microphone?

I recommend watching several videos of different performances and interviews using a lavalier microphone so that you know where it can be positioned and how to position it in case you do not want the microphone to be visible, in case you are wearing complex clothing, in case you are filming a topless actor ( there are such options) and I’ll also tell you how to take into account the features of a lavalier microphone, especially its sensitivity when the microphone itself rubs against clothes in the case when you hide it under clothes and how to avoid noise from this, and how to secure your own microphone cable so that its movements under clothes was also not picked up by the microphone.

So you need to know that the location of the microphone affects the sound. Here's a simple example: if you move the microphone from the second button of your shirt and attach it to the top of your shirt, you can probably hear the difference right away. The difference in sound in this place is obvious in that the upper frequencies are transmitted less, while the lower chest sounds are transmitted better.

Personally, I think that this is not the best place for a microphone, but if there are no other options, it is quite suitable because speech is still quite intelligible. And yet, the location of the microphone a little lower, not at the level of the first or second button of the shirt, I think is better because upward is transmitted better by the microphone and this has a good effect on speech intelligibility.

I would like to immediately say that the ideal location of the microphone, which is used in studios and special microphones, is still the microphone located at the mouth of the speaker, this is the best location, which is used in sound recording, in recording vocalists, but spoils the picture in the case of an interview.

How to use a wireless microphone

A wireless microphone is a device that performs all its functions without a cable connection to other devices. Therefore, it always has an independent power source. Before starting operation, you need to make sure that the battery is in its place and the battery is charged. Next, depending on the external device, you need to select and activate this type of microphone in the sound settings. If you are using a Bluetooth voice device, it is turned on as follows:

• Power on the micro to activate its functions
• On the external device, enable Bluetooth “Search”
• Select the desired voice device from the list and turn it on

In some cases, the operating system may prompt you for a password. By definition this is 0000. After this, the remote Bluetooth connection will be established. If the micro will be used for karaoke, you need to install any sound file and set the volume level, high and low frequencies. How to use a wireless microphone. You should not bring the micro too close to the sound source, as this will cause wheezing and distortion. It may be difficult or impossible to operate wireless devices in areas with strong electromagnetic fields. The quality of the broadcast sound largely depends on the choice of voice device. If it has a circular diagram, then the position of the sound source does not affect the quality of the transmission. A directional micro should be oriented towards the sound signal, so its sensitivity from the sides and behind approaches zero and the sound will be almost inaudible.

If there is only one connector

Most often, in situations where there is only one connector, it is intended both for headphones and a headset. A number of manufacturers prefer to combine holes for connecting various additional equipment. Try installing the device in place of headphones or speakers.

Connection via an adapter for non-standard equipment

Non-standard equipment cannot be connected to the computer. You will need an adapter, which you can buy at a specialized store. Then the plug of the audio recording device is inserted into the hole on the device, which is connected to the computer.

How to connect a wireless microphone

This is a device equipped with a receiver; it does not come with a cable. It has built-in speakers and a battery. You can connect it to a TV (techniques with a Smart TV function are best), a computer or a mobile phone with any Android or iOS operating system using bluetooth. You need to turn on Bluetooth and the device itself, and then the function on the paired device.

On your phone, the settings can be made in the “Sound and Audio Devices” item. It increases or decreases the volume.

All karaoke programs have a clear interface, it is possible to change the sound, connect the “echo” effect and other functions, but you need to make sure once again that bluetooth on your smartphone will be active.

We use it correctly

The microphone is designed quite simply, and embodies a harmonious combination of a local device and speakers in a wireless format. The device is connected to a mobile device via Bluetooth. Then you should install the application on your mobile device from the AppStore or the equally popular Play Market. The key phrase in this case will be “karaoke in Russian.”

If a song is launched in the application, the music is output to the microphone and speaker. After this, the preparatory stage is completed. A metal capsule is brought close to the mouth, and melodies are sung while simultaneously reading the lines on the screen. If you don't have a smartphone at hand, the task becomes even simpler. You should insert a flash drive or memory card into the slot and listen to your favorite backing tracks. You will have to sing based on your memory.

Advantages and disadvantages

Advantages:

• lack of connecting wires;
• versatility - you can connect the device via cable;
• range of about 10 m - you can sing not only indoors, but also outdoors;
• battery power provides up to 8 hours of operation (depending on volume level and model);
• affordable price.

Flaws:

• budget models do not have built-in speakers;
• Depending on the type of device, battery consumption may vary - there is a need to have a spare set;
• Not everyone has a direct connection to the recording device - some require a mixer;
• Wireless devices operating in the UHF range (300 - 3000 MHz) have a shorter signal range, so it is better to use equipment with a VHF range (30 - 300 MHz).

Bandwidth and Spectrum

Almost all wireless microphone systems use wideband FM modulation, requiring approximately 200 kHz of bandwidth. Due to relatively high bandwidth requirements, wireless microphone use is effectively limited to the VHF band and above.

Many older wireless microphone systems operate in the VHF range of the electromagnetic spectrum. Systems operating in this range are often driven by a quartz crystal and therefore operate at a single frequency. However, if this frequency is chosen correctly, the system can operate without problems for years.

However, most modern wireless microphones operate in the UHF television range. In the US, this band extends from 470 MHz to 614 MHz. In 2010, the Federal Communications Commission issued new rules for the operation of TV-band devices. Other countries have similar range restrictions; for example, the UHF TV band in the UK currently (January 2014) extends from 470 MHz to 790 MHz. Typically, wireless microphones operate on unused TV channels ("white spaces"), with room for one to two microphones per megahertz of spectrum. ("Wo Mic")

Intermodulation (IM) is a major issue when operating multiple systems in one location. IM occurs when two or more RF signals are mixed in a nonlinear circuit such as an oscillator or mixer. When this happens, predictable combinations of these frequencies can occur. For example, combinations 2A-B, 2B-A and A + BC may occur, where A, B and C are operating frequencies. If one of these combinations is close to the operating frequency of the other system (or one of the original frequencies A, B, or C), then interference will occur on that channel. The solution to this problem is to manually calculate all possible products or use a computer program that performs this calculation automatically.

Digital Hybrid Wireless

Digital hybrid systems use analog FM transmission circuitry combined with digital signal processing (DSP) to improve the system's sound. The use of DSP allows the use of digital techniques not possible in the analog domain, such as prediction algorithms, thereby achieving a flatter frequency response across the audio spectrum, as well as further reducing noise and other unwanted artifacts compared to purely analog systems.

Another approach is to use DSP to emulate analog companding circuits to maintain compatibility between older analog systems and new systems. Using only DSP in the receiver can improve overall audio performance without sacrificing the increased power consumption and resulting reduction in battery life that comes with incorporating DSP in a battery-powered transmitter.

Setup instructions

Each device has different settings depending on the model. In order to start using the device, you need to complete the following steps:

• turn on the device, then the indicator will appear and show that the bluetooth function is enabled;
• on the paired equipment, find the model identifier in the search bluetooth menu and connect to it;
• open any karaoke APP or select a music file on the device’s player;
• adjust volume, frequency and bass.

Lists of the best!

The presented models are aimed at average buyers and their needs. But a portable speaker with Bluetooth and a flash drive has wider functionality and a wider range of models. Therefore, we bring to your attention an additional rating of the best speakers according to various criteria.

• Convenient control, beautiful design and loud sound - BBK BTA106.
• Loud, high-quality and strong – Tesler PSS-555.
• Best Bass – Bose SoundLink Mini Bluetooth speaker.
• Budget portable speaker – Defender Moon Solo.
• Lightweight and small budget speaker – Xiaomi Square box Cube.
• A speaker with the ability to recharge a smartphone from it – Philips BT7700.
• Expensive, powerful and large speaker with excellent sound – Harman/Kardon Go Play Mini.
• The best speaker system under $100 is the JBL Flip 4.
• Beautiful design and useful functionality - GZ electronics LoftSound GZ-22.

Rating of popular models

Portable devices with a speaker and complete with a receiver are distinguished.

Portable with speaker

The leader is the Tuxun (MicGeek) Q9 model. It has bluetooth 4.0 and supports ios and android, there is a usb and microusb slot. There are stereo speakers, supports Bluetooth connection at a distance of up to 10 m, and operates for up to 9 hours.

Magic Karaoke YS-86. The brand is used as a speaker or plays songs. There is a slot for memory cards, aux-in, usb, LED backlight, battery life up to 6 hours.

Standard connection

Hopefully you already have a microphone for vocals. Typically, relatively simple models are sold in specialized music stores and computer stores. Moreover: in computer systems it is easier to find a simple model, since professional musicians and presenters often need expensive specialized devices.

Often a microphone (or two) is included with a music center or DVD player. If you bought an advanced model, then you may not have to buy anything additional.

If you are buying a model specifically for home vocal parties, then pay attention to several factors:

1. Microphone type. Between dynamic and condenser, you need dynamic: they are more affordable and do a better job in noise. Condensers are better suited for the studio.
2. Directionality. Since you need to capture one person's vocals, it's best to go with a unidirectional model.
3. Price. You shouldn’t overpay for professional models: regular karaoke options for 1000-1500 rubles are quite suitable. Although the expensive ones will deliver better voice quality, remember that you are limited by the capabilities of the sound card and speaker system.

How to choose an external microphone for a smartphone

Choosing a microphone is one of the important steps that must be overcome by anyone who wants to record high-quality sound on their device. In fact, there are several criteria that are the basis for selection:

1. Wire length;
2. Goals;
3. Micro size;
4. Equipment;
5. Device compatibility;
6. Frequencies;
7. Cardioid regulation.

It is worth examining each point.

The length of the wire is how far the user can move away from the smartphone and the sound will still be good since the microphone is connected. A wire that is too long is just as inconvenient as one that is too small. It is worth finding a middle ground.

Purposes are what the device is used for. It is necessary to decide on the type based on the purposes for the device.

With the size of the microphone, everything is simple: the larger, the higher the quality. Video bloggers are advised to purchase fairly small devices, but musicians should pay attention to larger models.

It is important that the microphone comes with additional equipment in the form of an adapter or wind protection.

Not many appliances can be combined with devices. This is also worth paying attention to.

Frequencies are an important point. If a microphone has a range of more than 20,000 Hz, then this device is clearly of poor quality. The equipment must be of high quality. The ideal range is 60 – 15000 Hz. If it is higher, the ear simply will not catch it, the device will concentrate on extraneous noise. For example, for a blogger, a low indicator is an advantage, since basically the microphone will only pick up the person’s voice, and not extraneous noise. For musicians, it is important that all sounds in the room are heard in order to create a high-quality picture, which is why the maximum range is an excellent solution for them.

The last point is unclear - this is a cardioid. In fact, this is a circular diagram of the microphone, that is, its regulation. Setting this indicator means that the user has the ability to completely adjust what the device will hear. This can be just the voice itself, or you can also set it to capture the entire room. This is a great opportunity to regulate the recording process.

Weight, these characteristics must be indicated along with the device, in its settings.

Using third party programs

There are many third party programs that allow you to control your microphone and apply various effects to the audio you receive. The company that made your microphone may have their own application, which you can find on the manufacturer's official website. Below we will discuss just a few of the most convenient and well-known applications.

Free Sound Recorder

How to set up a microphone in Windows 10 in other ways? You can use third party applications to capture and record audio. There are many such programs, but we will mention only one - Free Sound Recorder. This simple and free app can record audio from a variety of sources, including a microphone, and has the ability to customize source settings. Let's look at the microphone settings in Free Sound Recorder as a specific example.

TOP best external microphone models

To make it easier for the user to choose a high-quality microphone model, it is worth looking at the rating table, which is formed not only from reviews, but also from the experience of many users from different fields: musicians, journalists and many others.

This way you can easily and simply not only connect an external recording system, but also select it.

Peculiarities

Karaoke microphones with Bluetooth have a number of unique characteristics that will be useful to know about.

The absence of wires is one of the main advantages that sets such devices apart. Wires usually get tangled, interfere with free movement and get caught.

The built-in battery can withstand an average of 6 hours of operation. This feature allows you to take karaoke with you anywhere, which is very convenient.

Automatic voice correction and improvement are built-in functions of such devices. Everyone will like them, since few people like the voice in its raw form. Miniature mixers cannot compare with professional devices, but they still do their job, and the results of their work are pleasantly impressive.

Many wireless models allow you not only to sing, but also to listen to your favorite music and even create recordings.

Connecting an external microphone to a non-Android smartphone

The algorithm for connecting a sound recording device to any smartphones running on other systems is similar to the methods described above. Almost all modern phones are equipped with a standard jack (3.5 mm). To connect an external device, there are a large number of adapters and various adapters. Every smartphone must have a Bluetooth connection. Therefore, wireless switching of various products is quick and easy.

It must be said that the newest iPhones do not have a miniJack connector, so it is impossible to use headphones. For switching, you can use the Bluetooth function, or special adapters with an iPhone connector.

Important! Several adapters affect the recording quality. It gets worse as the signal undergoes multiple conversions.
