In the era of digital technologies, the analog television was not to affairs, as the televisions of the past epoch were strongly lost in their versatility. They are not able to read the USB flash drive, there is no possibility to connect an Internet cable to them. And now they are also unable to perceive some video signals. Of course, the best solution will change the old technique, the technique of his age. But there is a simpler solution - the receiver for the TV.
What is Receiver
The receiver for the home TV is used to convert signals. When receiving a digital video signal, it instantly, without delays and interference converts it into analogue, which is capable of perceiving ordinary TVs. Given that in the near future we promise to broadcast all television channels only in digital format, the presence of such a converter is very desirable. This prefix will not need some categories of users:
- Those who have fundamentally refused to watch TV;
- Who uses cable operators;
- owners of modern TVs with a built-in converter;
- Who to view all the necessary channels is enough.
The receiver itself has a compact size, does not take up much space, it is easy to connect and configure it. With further operation, it is not necessary to make any adjustments. Only in the case of connecting additional equipment.
What else do you need a receiver? It can be connected to two separate TVs for simultaneously broadcasting various gears. You can also connect two separate videos on one screen, create simultaneous broadcast of multiple gears with the "Screen Decision" function. The presence of a hard disk will allow you to store and subsequently view a large number of different information in various formats. In addition, the recording on a hard disk or a flash drive can be carried out simultaneously from several channels (usually not more than 3, the number of channels is adjusted depending on the selected model).
Functional features of the receiver
It is difficult to imagine what the receiver is for the TV, if you do not understand how it works and in which the basic functional features of the device. First of all, it is necessary to understand the principle of receiving and transmitting information to the analog and digital devices.
Digital channels All incoming signals are taken in one package, after which they are transmitted to the receiving device, where the processing and decryption occurs. This allows you to get all the information in first-class quality, regardless of the power and the capabilities of the antenna. Excellent result is provided even in the presence of the most ordinary room antenna, and in some cases at all without it. The receiver provides the following advantages:
- clear, powerful and smooth sound;
- high quality image;
- No interference, tip, noise;
- Lack of fees, as when using cable television.
Any TV prefix allows you to connect a large number of programs, configure and sort them at your discretion. Many users of this device mark the ease and ease of operation of the receiver. In addition, depending on the selected model, you can get other advantages of using the receiver:
- Video recording. If a favorite series has begun, and at this time you have to go to the doctor, you need to pick up a child from the kindergarten or urgently to take a mother-in-law on the cottage - it is only necessary to choose the time to start recording and you can easily go to your business, and returning to enjoy the desired video;
- Ether delay. It will be useful for those who are forced to regularly pass the esters due to the difference in time zones when the transmissions are broadcast from the USA, China, Australia. This feature is convenient and in the case when your favorite transmission goes during working hours. To activate the delay of the ether, you should only specify which difference in time the selected channels will be played;
- Built-in hard drive. In this case, the digital receiver for your TV becomes a full-fledged media center to which additional devices can be connected;
- Children's control. Allows you to block the view of some gears, as well as limit the time to view them.
How to connect the receiver: types of connections
Connecting the console does not take much time and make a mistake at this stage, even using various devices, almost impossible. The main thing is not to forget what exactly should be connected and which connection is necessary for each case.
Another name of this compound is "Tulip". Such a cable is connected to the usual TV. Provides a clear and accurate image, easy distortion is allowed if the picture is projected on TVs with a large diagonal. In other cases, differences using the HDMI cable are completely invisible.
To connect the RCA cable, you must perform actions in such a sequence:
- The receiver and TV are dealers;
- The cable is connected to the console, each plug has its own color, which allows you to unmistakably determine the socket for which this plug is intended. The video signal passes through the canal with yellow marking, the sound row is transmitted over white and red, but they are not interchangeable;
- After that, the antenna is connected, the receiver and the TV are included in the network and the equipment is configured.
Designed to transmit signals in high quality. If there is a HDMI connector on the TV, it is recommended to use it for connecting the receiver. The order of connections will be the same as when using RCA. The main feature of this type of connection will be the selection of the cable itself. It is recommended to choose the most short cable that will provide more accurate and fast data transmission. In addition, you do not have to decide the question where to give extra wires.
How to connect a digital receiver to a very old TV, which from all types of connections only an antenna is provided? In this case, it is necessary to use this type of connection, only one should not count on a good picture quality, the sound will also be transmitted with a significant defect. But in this case, this is the only possible option for obtaining a more or less acceptable connection and signal transmission to the TV.
In this case, the method of connecting the receiver to the TV through the antenna cable is described. At the same time, you should not forget that the receiver itself must be connected to the antenna. It can be an ordinary room antenna, cable or satellite TV. In all three cases, it is defined through the corresponding connector on the receiving device.
Tips for selecting receiver
The need to buy the receiver arises, as a rule, in the elderly who do not plan to update their homework and at the same time spend a lot of time in front of the blue screen. Their selection criteria are always limited to the opinion of the neighbor, girlfriend, telemaster and price. In fact, the criteria for choosing a receiver to broadcast digital television a lot:
- Broadcast format. Despite the fact that all channels are transmitted in DVB-T2 format and all modern receivers can perceive only such a signal, you can still find older models on the market, which work with outdated technologies, including DVB-C, DVB-S ;
- Additional features, including: reading information from flash drive, recording, player;
- Support for various formats. What they are more, the more versatile the device will be. With it, you can play various videos and audio files;
- Simple setup and receiving control, availability of instructions and menus in Russian.
The receiver may be needed not only for old TV models, but also for more modern models that work with digital formats, but their functionality is strongly limited. How to expand the capabilities of the receiving device and why do you need a receiver to digital TV?
View Paid Channels. Not all channels are freely available and a special card with the encodings of the desired channel (or several channels) is required to view them. Pre-at the provider should find out which codings are used and what cards you have to use. Only after that the receiver is selected, capable of working with the selected type of cards. If it is assumed or simply, there is a possibility of changing the provider, it is worth considering the option of buying a receiver with several different slots under the modules of different types. This will make it possible to view the channels that you want.
Another problem of some TVs is the lack of necessary connectors, which prevents them from connecting them to a computer, smartphone, various video players. Refix the situation will help the receiver with USB, HDMI, E-SATA connectors and others. It is only necessary to determine which equipment and technique will later be connected to the TV. There are also universal models that have all possible connectors, a variety of devices can be connected to such a receiver.
The rapid development of digital technologies led to the fact that every day on shop windows and commercials, we offer all the more advanced TVs that can broadcast in a wide variety of formats and providing excellent sound quality and a clear image. But few people agree to buy a new TV every six months. How can you be aware of modern technologies differently? It's just enough to install the receiver:
- The newest models are easily coping with various formats, among which MPEG-2 and MPEG-4, and the quality of the picture is represented not only in HD, but also in more detailed 4k;
- It will be easy to find a sign converter that will provide a picture in 3D;
- The receivers functionality expands constantly. Given that they can work with different sources of signals, including can be connected to the Internet or satellite antenna, read flash drives, receive data via Wi-Fi, and also be an independent multimedia device, the possibilities of such a converter are simply not limited. With this device, it practically does not matter which TV is installed in your home;
- In addition, the receiver can be used at all without a TV, it connects to PC , smartphone, tablet, significantly expanding the functionality of this technique.
Each your own: AV receiver or stereoxeller?
Save and read later -
When planning the acquisition of certain components of the home audio system, the future user faces a large number of questions in which it is not always possible to deal without a specialist. As a result, a set of components can be obtained, which, maybe it sounds well, but does not deliver pleasure to his owner. Why is that? It's all about the nuances that sometimes are decisive. For example, choosing a component responsible for switching and enhancing sound.
Amplifier or receiver? This question asked himself almost anyone who planned the purchase of new audio engineering. For someone, it was supposed to become a new purchase, and someone upgraced the system already existing, trying to bring more opportunities to it and improve the sound. And at the stage of choice, many were in the wrong side. The problem lies in the misunderstanding of the principal difference between these two devices. And she is. Let's try to figure out ...
So, let's start with the features of the choice of technology today. We are accustomed to advertising to choose what has the highest possible set of functions. Naturally, in the future we will not use half of this, but at the selection stage we vote the wallet for extensive opportunities. So, choose the AV receiver. What is, in essence, this very receiver? If you do not fit into technical debursions, it is essentially an amplifier, only not stereo, but multichannel. Traditionally there are at least five gains. And with them in one case there is a switching system, decoding, processing. That is, it is the default device more comparison compared to the stereo substitute. And, having some strictly defined amount of purchase, the average buyer chooses what more functions. At the same time completely ignoring their true needs. And this choice is very simple. If you are planning to listen to music most of the future of the future system, then you better pay attention to the stereo amplifier. And if you're an avid kinoman, and the music is for you either like a rare pastime or as a background, then in this case you need an AV receiver.
Why is that? Why Melomanana is not worth buying a receiver? It's all about the features of its design. As we have already understood higher, at the same cost we can buy either a simple amplifier or a more complex AV device. However, in the receiver, we have more functions, which means somewhere we are waiting for a compromise. And he is. This is an audio color. It is simpler and less demanding. First, the stereo uses better elements. Recalling again that we have a fixed amount for the purchase. From here you can make a logical conclusion that we will buy either two high-quality stereo channels or five slightly less good. We will not forget that we still have a processor, a set of decoders and a mass of switching electronics.
Secondly, audio artists for music and cinema are created according to various principles. For music, subtlety, sensitivity to the slightest change, "air" are important. At the same time, the celliforogram is full of powerful dynamic drops of sound effects, bright and clear tbsters that characterize this or that scene. If you simplify the description, then the music record allows you to hear and submit, while the Soundrtek in the movies accompanies the picture. Yes, in both cases, the sound creates a definite mood, but they are fundamentally different.
The features of the AV receiver circuitry are also opposed against demanding music. The fact is that most of the receivers from inexpensive and medium-budget ranges do not have the ability to disconnect the sound processing unit: equalizer, spatial processor, decoders. And even if such a receiver is equipped with a BYPASS scheme with the ability to bypass the processor part, then the analog path still affects interference from working microprocessors. Many AV devices allow the "trick" - connecting the stereo signal directly to the multichannel input if the receiver is accommodated. In this case, the music really sounds more natural and volume. However, as we have already spoken above, the design of the receiver amplifier is such that a certain part of the music does not reach the speakers, as it gets lost in nozzles from the electronics of the electronic part and forever subsides in the audio code itself. It is unlikely that Meloman Audiophil will be happy to such a result.
So what to do? We think it is already understood. Appliances need to be used strictly by its primary purpose. That is, if you like movies, choose the AV receiver. However, if you are Meloman, you forget about all additional features and multichannel sound. Anyway, you will not be regularly used. Better pay this money for higher sound quality.

We choose meaningless
The term AV receiver is constantly on hearing. It is well known that this is the central link of the home theater system - the cornerstone, which takes on the coordination of the work of the rest of the complex components. What tasks he performs how it works and why it is not able to replace the Soundbar, nor a pair of a spherical television? Let's try to figure it out in this article.
The main task of the multichannel AV receiver is the decoding of a digital audio track, accompanying a film or a program, an aligned transformation of a digital stream into an analog view and gain of each channel. But, of course, by solving the main task, the functionality of the modern AV receiver is not limited. First of all, such an apparatus processes not only audio, but also video signals. At a minimum, he takes over the switching of sources and output video to one or two display devices. In addition, the AV receiver is used not only to view movies and various video programs, but also for listening to music - both in the multichannel version and in the classic stereo. At the same time, a source of audio is often built into the receiver - at least, analog and digital tuners, and in recent times there are more and more models that can fight music from the network.
The presence of a serious computing platform in the AV receiver allows not easy to decode soundtracks, but also to produce various material pre-processing. The most common recently was the implementation of various automatic sound calibration systems for the acoustic features of the cinema. In operation with video signals, in addition to switching in the AV receiver, it is often scaling (enhancing the resolution), as well as the transfer of analog video signals into a digital form for subsequent processing and output through the HDMI port. AV Receiver
- This is a multichannel amplifier that accepts and converts sound, video and radio signals from different sources. With it, you will get the excellent sound of the audio system, high-quality image and sound of a home theater or a regular TV.
The receiver is a brain center of your home electronics, it is he who combines all sources of video and audio into a single system in your apartment. This device literally per minute change the signal source and output channel. For example, you just watched movies from a DVD player on a home theater, enjoying the surround sound reproducible by the speaker system. And after a minute you can listen to your favorite music from the computer supplied to the built-in speakers. The receiver controls the signal to be properly decoded, reinforced and switched depending on the selected source, and you were able to enjoy high-quality sound and a flawless picture on the screen.
Functionality AV receivers
Strengthening the signal
Since the receiver is still a multichannel amplifier, its most important function is a signal amplification. How does this happen? An audio signal is received from the player, television or other source connected to the receiver. If it is digital, then the receiver first converts it to an "analog", and then enhances to raise the volume or adjust the frequency level (high, medium, low). And then with the power amplifier, the receiver helps to achieve juicy bass and get rich sound at low frequencies.
Video signal switching is a function that any receiver is performed. His task is to merge into one all video signals from several sources (for example, a DVD player, a PC, TV), which allows you to free your room from the wires of the wires and easily manage all available video sources.
All modern DVD and Blu-ray discs have a multi-channel record, that is, each column has its own soundtrack with a specific content and volume. The parameters of each audio track are recorded on the disk as codes. To get exactly the sound that is recorded on the disk, the receiver must correctly decode the information, and for this it is equipped with special decoders. The more encoding formats perceive your receiver, the more different disks you can play. Modern AV receivers
Work with Dolby Digital and DTS formats. To play a Blu-ray and HD DVD discs, the receiver supports new "High Resolution" formats - Dolby Digital Plus, Dolby Truehd, DTS-HD Master Audio and Uncompressed PCM signal.
Some AV-receiver models have a DSP digital sound processing system. Such receivers can give sound special effects - such as presence in the stadium or in the temple. If you like such experiments with sound, pride such a function from your receiver.
The presence of a function Multifunction says that the receiver can "voice" several rooms at once in your home. How does this happen? With the help of a special button, two additional amplifiers from the receiver simply switch to the next room. Moreover, depending on the model of the receiver, you can redirect not only sound, but also a video signal to the adjacent room.
Automatic sound tuning
Many modern receivers are equipped with an autocalibration function, or automatically adjust the sound parameters. To do this, complete with the receiver is a control microphone, which allows you to adjust all the sound channels, taking into account the size of the columns, the distance to them, the acoustic features of your room, the height of the ceiling, area and other listening conditions. The main goal of such adjustment is to configure the optimal volume of sound, time delays in different channels and create the most comfortable sound tonality.
Functions of "improvement" video
In some receiver, there is a function of how to enhance the video with which you can convert video to higher quality format (for example, with PAL to HD). High-class models additionally allow you to customize sharpness, resolution, color balance and brightness for individual sources. Receivers of the latest generation increase permission up to the newest format 4K, in which "fit" four times more pixels than in Full HD. But this feature is available only if the TV or the projector supports this format.
Thanks to the built-in video converter, different signals are converted into the same type (for example, composite into component or all analog in digital HDMI). This means that connect the player, PC, the camcorder or the game console to the receiver can be using a single cable.
Control in one remote control
The high-end receiver models occurs the function of the tract. This means that all devices connected to the receiver can be controlled using one remote control.
Input and output interfaces
The rear wall of the receiver is able to scare any inexperienced user - after all, there are so many connectors of different shapes and diameters, which is easier to get confused. In practice, a large number of input and output interfaces means that you can connect to the receiving even the most outdated models of devices.
Here is a standard list of interfaces that the AV receiver must have.
Sound interfaces RCA
- Analog stereo sounder is connected through this connector. Often the interface is needed to connect an audio magnetophone or CD player. S / PDIF.
- Interface by which sound data is transmitted in digital format. This interface can be two types - coaxcal with RCA connectors and optical with TOSLINK connectors. The second transmits a higher quality signal, since it is reliably protected from external influences like magnetic fields capable of affecting the quality of the signal.
Interfaces for video transmission A / V (Composite RCA video)
- This is the most "ancient" of all interfaces for transmitting an analog video signal. It is present, perhaps on any TV, console, camera. The interface consists of three connectors, one of which is transmitted video, and on two others - sound. The RCA interface cannot provide high signal quality and image clarity. S-video
- The connector of this type may be needed to connect game consoles or DVD players. The interface provides good signal quality, a clearer and colorful image compared to the composite video. Keep in mind that with the help of S-Video, you can only connect a picture, the sound is connected via other interfaces. SCART.
- Through this interface, you can connect a TV and other technique equipped with a similar sound and video connector to the receiver. This interface can maintain stereo sounds, S-Video, RGB. Component interface
- This connector allows you to transmit high-definition signals by resolution up to 1080i, in particular, suitable for HDTV transmission. To connect equipment to the receiver through the "component", it must have appropriate outputs, and the TV or the projector must have component inputs.
Among the analog signal transmission methods, the component is the most perfect and gives the best quality when broadcast analog image. HDMI
- This is not only a modern, but also the most universal type of digital connection, according to which high definition video and multichannel sound are simultaneously transmitted. To connect a receiver with such an interface to a TV or a projector, you need only one cable of the appropriate type. Today, each modern receiver is equipped with several HDMI connectors for connecting multiple devices simultaneously.
Using AV receivers with other equipment
Any receiver is designed to use in tandem with other techniques. The only question is how wide the possibility of one or another receiver in terms of compatibility with other equipment.
A standard list of devices that can be connected to most AV receivers are TV, DVD or Bluray player, projector, VCR, Camera, Camera, Game console. There are models that are compatible even with players of gramophone plates.
Most modern receivers have interfaces for connecting to MP3 players, "iPhones", iPods, PCs and other computer equipment via USB, Ethernet cables, HDMI ports, as well as external hard drives via USB port.
The newest models of receivers suggest the possibility of connecting special docking stations for the iPods. Most often, the docking station must be purchased separately, since such receivers have only a special connector for their connection.
Docking stations transmit video, sound and can charge your iPod player battery. It is convenient that through the receiver menu, for example, using the remote control, you can control the player.
If you do not suck and buy a receiver that supports built-in wireless technology - AirPlay, Bluetooth, Wi-Fi, you can use a smartphone, a tablet and other computer technique to play music or video through the receiver.
If you select the receiver model, consider such a nuance. Bluetooth can work with any tablet or smartphone within a radius of 10 meters and gives a slight reduction in sound quality, and airPlay technology is in most cases only for working with "apple" devices, requires that the receiver is connected to a home network, but it provides the highest quality Sound.
Even if you bought a receiver that does not support wireless technology, you can add AirPlay and Bluetooth through external modules, but, of course, the built-in option is much more convenient. Some models are so "smart", which automatically activate the necessary interface as soon as you choose it on your tablet computer or smartphone.
If your receiver has also built-in Wi-Fi, you can easily connect to the home network to update the firmware, manage it from the smartphone, access streaming services.
With the help of wireless interfaces, you can connect a multimedia computer to the receiver, access your own musical collections, iTunes, Internet radio services and other features.
The wider the list of equipment with which the receiver can be used, the higher its price. In order not to overpay for unnecessary functions, it is better before buying to decide which technique you plan to use in tandem with the receiver, and that you definitely do not need.
Software "Stuffing" receiver
Even if you buy an ultra-modern receiver with the latest generation software, this does not mean that a year later, and maybe several months, this "firmware" will still be relevant. Manufacturers and programmers regularly finalize, improve the "firmware" of receivers so that they provide the best operation of the device.
These updates can usually be found on the Internet, on the manufacturer's website, on special enterprises or in the menu itself. They can be downloaded from a computer, a regular flash drive, another receiver with a new "firmware", from the network or from a satellite.
Why change the "firmware" of the receiver? What does it give?
The software update will help get rid of hanging and other failures in the receiver. The device will start working faster, will accurately execute commands and react to the remote control. It is possible that new channels will appear in the updated "firmware", new functions will work, the receiver will be able to read media files from external media, go online to see the weather forecast or videos on YouTube. Lovers of high-quality sound will appreciate the special "firmware" for 3D sound.
As you can see, updating the software is able to improve the operation of the receiver, and therefore, do not forget to "reflash" your device from time to time. The main thing, be careful and choose the software for your model of the receiver. Incorrectly selected "firmware" is able to spoil your receiver so hard that you have to buy a new one.
AV Receiver Management
The receiver is controlled from the two components-perverse installation of all settings and directly adjustments during use.
How wide will the possibility of receiving the receiver, depends on the class and the cost of the selected model. What these parameters are higher, the "smarter" and thunder than the control system.
- In general, to control the receiver in the following ways:
- using the buttons on the device itself;
- using the remote control;
- through the web interface of the device and computer connected to the local network;
- with the help of special installation programs and a computer on the local network;
Through "iPhones", "Apads" and similar devices on Android.
The most familiar and affordable method of controlling the receiver remains the remote control. Often, the buttons on it are broken into several groups for ease of use, and the remote control itself is universal and is suitable for controlling different devices connected to the receiver.
The control version through the web interface is more suitable for those who spend a lot of time at the computer - for example, handles music and parallel reproduces it on home acoustics.
The most modern and convenient option, perhaps, can be called the receiver control using mobile devices.
If you have long been with smartphones and tablets on "You", you will probably like the "Mobile" method of controlling the receiver. To connect such an opportunity, you need to download the appropriate application from the manufacturer's website, AppStore or Google Play, install it on your tablet computer or smartphone - and the mobile device will turn into a touch remote control for the receiver. Such applications are free, but only work with gadgets of the relevant manufacturer.
Quality applications allow not only to use the main remote control buttons, but also give a lot of additional features like setting the sound in the second zone, convenient navigation on the network, setting the auto-disconnect timer, and even wireless downloading of music. True, to enjoy all the additional features, your receiver and smartphone must be connected to the same network - do not forget to control this moment.
Test, as a specific application works, it is possible and without connecting to the network - it is enough to choose a demo mode.
Keep in mind that it is possible to fully manage all the functions of sound and pictures, you can only with new models of receivers, and pumping music libraries allow only top receivers.
In order not to be unpleasant surprises, make sure that the device has applications for remote control, which are compatible with tablets or smartphones based on iOS or Android, - depending on which mobile device you use.
The receiver control using the touch screen attracts its clarity and dynamic adjustment to any situation. In addition, the smartphone is the gadget that is always with you, and the risk that you will lose it is almost equal to zero. What you can not say about the consoles do.
The only inconvenience of the receiver control using a smartphone is that the mobile phone must be pre-switch to the remote control mode. But compared to the rest of the benefits of such a control, you can close your eyes on such a slight minus.
Critical parameters when choosing AV receivers
Choosing a receiver, you can rely on your ideas about the nature of the sound, convenience of use, design, but there are a number of parameters in which mathematical accuracy and the correct calculation are required. If you make mistakes with the choice of receiver for these criteria, you risk getting at all the quality of which was calculated.
- In technical specifications, the manufacturer usually indicates the averaged receiver power, which does not give a complete presentation of the power of each particular amplifier. However, the characteristics of the capacity is of great importance for the proper selection of the receiver, and before purchase, pay attention to the recommendations:
- If you get the receiver for home theater, consider the area of the room. What it is more, the higher the receiver power must be for high-quality sounding of the room. It is believed that for playing DTS and Dolby Digital formats in a 30-meter room, a receiver is required to 70 W per channel.
- If the room under the home theater has acoustic processing, the stronger it is "muffled", the more powerful receiver will need for voice acting.
- And, of course, the power of the receiver should relate to the characteristics of the selected speaker system, otherwise you not only do not get a clean sound, but also risk in ordering all the technique.
- If you have a subwoofer in the acoustic system, the required power of the receiver also increases. This is explained by the fact that the subwoofer reproduces low frequencies, and for playing bass, the necessary significant power.
Selecting the receiver for a specific acoustics, consider that the higher the sensitivity of the speaker system, the less the receiver power should be and vice versa. For example, for a speaker with a sensitivity of 85 DB, the receiver power must be 100 W, and with a 91 dB sensitivity, the required receiver power index is reduced to 25 watts.
The choice of resistance receiver directly depends on the speaker system you are going to connect to it. The lower the resistance rate in the acoustics, the greater the load it gives the AV receiver, "demanding" from it more electric current. Some models simply will not "pull" such a load and will not cope with low-wedroom acoustics.
The optimal option is to buy a receiver whose resistance will coincide with the resistance of the speaker system. But still it is better to read in a passport before buying in the passport or on the rear panel of the receiver, the minimally allowed resistance of the plug-in acoustics so as not to force your technique to work at the limit of possibilities.
When choosing an AV receiver, weight is important. What he is heavier, the more powerful transformer is hidden in the design, and therefore you get a cleaner and strong sound.
Number of channels
Another important parameter - with which column is able to work the selected receiver, or how many amplification channels. And here, too, it is necessary to focus on the already existing or potential acoustics.
Today, the most common models have a five-channel and semi-channel gain, more expensive models are able to strengthen the sound at once nine and eleven channels.
If your speaker system has five columns and one subwoofer, the five-channel receiver will be the best option for it. Make sure that the receiver supports two main formats that give the sound to Puzzle National Systems - Dolby Digital and DTS. In seven-channel receiver must be support for Dolby Truehd formats, DTS-HD Master Audio.
Number of zones
All AV receivers are suitable for voicing, at least one room. But there are "advanced" models equipped with a multi-function function with which several rooms can be served immediately. Receivers from the average price line more often support two zones - for example, they give five-channel sound for home theater and stereo sounds for the bedroom.
Top models of receivers with 11-channel amplification can voice up to three or four zones at the same time.
Number of interfaces
When buying a receiver, it is important not to be mistaken with the number of inputs and outputs that you need to connect all the desired techniques.
First of all, you need to calculate in advance how much modern HDMI digital inputs you will need, because today all more or less modern techniques are equipped with HDMI outputs. When you counted your televisions, projectors, game consoles and another electronics that you will connect to the receiver, add to the resulting amount even one HDMI input about the reserve is the number of interfaces that you need.
If you plan to connect an old generation technique to the receiver, which is not equipped with a digital interface, make sure that the selected model has suitable connectors. The presence of a serious computing platform in the AV receiver allows not easy to decode soundtracks, but also to produce various material pre-processing. The most common recently was the implementation of various automatic sound calibration systems for the acoustic features of the cinema. In operation with video signals, in addition to switching in the AV receiver, it is often scaling (enhancing the resolution), as well as the transfer of analog video signals into a digital form for subsequent processing and output through the HDMI port. So,
- This is the central element and brainstall of all home electronics. From how accurately and right you picked up the receiver depends on the quality of the sound of modern acoustics, and the image clarity on the home theater screen, and the possibility of using the receiver with modern gadgets.
If the choice is made correctly, you can easily control the single complex of electronics using the console or smartphone and do not think about how to switch the sound from the audio system to the computer columns or redirect the image from the TV on the home theater screen.
Therefore, before making a purchase, carefully calculate all the parameters that your receiver must match, and choose the device in the shower, but with a support for the exact mathematical calculation.
At this stage of development, these devices became truly versatile and multitasking. In favor of the ever-increasing demands on the part of consumers, the functionality of modern receivers undergo many changes, to figure out which sometimes is not easy. In this article I will try to illuminate the most significant moments, relying on which the reader will be able to navigate throughout the variety of receiver.
Sound - first
Undoubtedly, one of the most important criteria when choosing an AV receiver is its compliance with modern configurations for connecting cinema acoustics. As a rule, in modern devices, the initial configuration is 5.1.
Having given these parameters, the receiver will voicate five columns and one subwoofer. Continue line of system configurations 5.2, 7.1, 7.2, 9.1, 9.2, 11.1 and11.2. Also meets format 13.2, but so far it is a lot of top receivers from the pair of troika manufacturers. The "golden middle" will be support 7.1 or 7.2 - such systems allow you to achieve a rather high level of voicing video.
Thus, the selection of the receiver first should be based on the composition of the system, which is already in the cinema or is considered to be purchased. Also, do not forget about the impedance of acoustics - it will not be superfluous to make sure that it is compatible with the receiver who fell choice.
If in the plans, in addition to watching movies, there is an organization using a stereo receiver - pay attention to the support of the selected device of high-quality audio formats: FLAC and DSD. Usually, the support of such formats means that the receiver is installed on board a highlighted DAC, which is favorable not only on listening to music, but also on video sounding. For gourmets on the market there are even models with a built-in phonological director.
A few words about power: Naturally, the more powerful the receiver is more expensive. But if the size of the room in which the arrangement of the cinema / music zone is assumed does not exceed 20 square meters, there will be enough receiver with ordinary power parameters - it is 80-110 W.
But the correlation with acoustic systems is also important. Here you need to remember that the power that the manufacturer indicates the characteristics of the receiver is, as a rule, the peak load on one channel, and all channels will not be able to reproduce this power. But this is not a reason for concern, since when videoed voicing, there are practically no such scenes, where peak power will be needed simultaneously in all receiver channels.
The same topic is close to another parameter to which many attached great importance is the gain class that is used in the receiver. Most of them work either in a durable AB class, or in class D. It is worth considering that the work in the class AV is accompanied by a much greater heat release than in the case of class D.
Consequently, there should be enough space around such a receiver for its comfortable and timely cooling. Receivers with gain in class D are less demanding of cooling, but it is still not worth putting them in a wardrobe.
To the same item can be attributed to the function of automatic sound correction in accordance with the room in which the cinema system will be equipped. Such an option is present in almost all modern receivers. To date, there are several of its variations (Audyssey, Ypao, DCAC and others). One of the most successful among them is the Audyssey. This feature will greatly facilitate the process of setting up and coordinating acoustics with a room.
Separate attention should be paid to the support of the multi-system system. This option allows the receiver to voice several zones (rooms). There may be two such zones, three or more - depending on the possibilities of the receiver. At the same time, the sound of both one and from different sources is possible in each of the zones at the same time. Multiform can be both wired and in wireless implementation. And if everything is clear with wired implement, then we'll talk about wireless in the next section.
Connections with wire and without
Undoubtedly, one of the most common switching options in this segment is HDMI. This interface can be found almost on all modern multimedia devices. Therefore, of course, it is important how the receiver is located in which the incoming HDMI ports.
The number of ports should be correlated with the number of devices that will be connected to the receiver on this protocol - be it a game console, Blu-ray player or TV. As a rule, modern AV-receiver models have 4-6 and more HDMI inputs.
Will not be superfluous and USB connectors. To use external information media, the best connection method has not yet come up.
Considering wireless interfaces, it is worth considering which of them will be relevant for a particular buyer. Because Currently, in the arsenal of receiver, you can find almost all existing protocols and interfaces of wireless data transmission: Bluetooth, AirPlay, DLNA, Wi-Fi (often even dual-band - 2.4 and 5 GHz), as well as all sorts of cutify services (Spotify , Tidal, Deezer, etc.).
Separately, it is worth allocating the wireless implementation of the multi-system system, since to ensure its work requires support for special multi-platforms both by the receiver itself and the wireless acoustics participating in the multicam. Some of the most popular platforms: Sonos, MusicCast, Heos, DTS Play-Fi, AirPlay 2 and Chromecast.
All this is created in order to facilitate the user the process of creating and managing zones Multifunction: most of the platforms have in their arsenal as an application for the smartphone and control using various voice assistants.
By the way, about voice assistants. With certain scenarios, this option greatly simplifies control of the AV receiver functionality. The device can keep working with all voice assistants at once (Amazon Alexa, Google Assistant, Apple Siri) and work only with any one of them.
Using voice commands, you can turn on or off the AV receiver, adjust the volume, fully control the playback of music, disable / enable sound, change the selected input to the AV receiver, link or cancel the connection of the rooms in the multi-configuration of the system, control the playback of music in different rooms.
In general, such an option carries an additional useful functionality, which displays the receiver control to a qualitatively new level.
An application for a smartphone can be attributed to the same useful additional functionality with which the user has access to most receiver functions. Before purchasing the device, it is necessary to clarify the presence of such a management method - of course, if this option is relevant for the buyer.
Working with video
4K resolution Every year, everything confidently develops gigabytes of content on the Internet. Now you can watch streaming video in this resolution even on popular video hosting. If the TV that will work in a pair with AV receiver has 4K resolution, it logically select the receiver with support for the same permission. The same applies to HDR - not all receivers are able to cooperate with HDR-TVs, without cutting this functionality in the latter.
Some of the AV receiver have additional means for processing the video stream. As a result, a certain upgrade is obtained, which in some cases allows you to more comfortably perceive visual information of mediocre quality on high-resolution TVs.
Once it came about the TVs, it is immediately worth mentioning the so-called Smart TV. Such a TV very often acts as a source of content, and all that is required from the receiver is a high-quality voice acting on the screen.
For such situations in some receivers, the HDMI ARC connector or EARC is provided for such situations (Audio Return Channel). It allows you to use one HDMI cable for both the receiver included in the receiver and the signal outgoing from the receiver, thus eliminating the setup from excess wires. Of course, such switching is possible if the TV also has an HDMI Arc connector on its panel.
Some of the models of modern AV receivers are also capable of multi-video. Simply put, they can simultaneously provide two monitors with a video content.
Of course, the choice of a suitable receiver is not a simple task. It often seems that manufacturers, equipping the receiver with an abundance of software chips and various DSP add-ons, set themselves only one goal - to frighten the consumer with a mass of comprehensive names and abbreviations. Even to simply voice each of the possible options, which is available in a particular AV receiver - would have to go beyond the framework of a laconic introductory article.
If the segment of the receivers in general is definitely certain of the most complex and most complex and multifunctional devices on the modern AV market. But you should not be afraid. As a rule, after the primary setting step, the receiver will not cause special concerns to the user.
Choosing the right AV receiver When choosing AV-receiver For home theater, you need to consider several factors. In the end, this device will serve as a controller and a central element of your stereo system or home theater system. Despite the fact that modern receivers have many options, it is important that your new AV receiver meets exactly your needs and was compatible with your source components, whether smartphones, streaming devices, Blu-ray players
or gaming systems. Having this in mind, the parameters of the wireless and wired communication are an important factor, as well as multi-speed, automatic speaker setup, video processing and much more.

Connecting loudspeakers for receiving
The most important connection you will do on your receiver is the connection of the speakers. Despite the fact that the connection of acoustics seems simple and obvious before you connect the wires to the speakers, there are several important things. The main among these factors is the number of speakers that you need and mapping these speakers with an AV receiver output. The number of speakers in your system is a personal choice; You must estimate the size of your listening room and decide whether you prefer stereo or multi-channel surround sound. Many audio formats and technologies, such as Dolby Truehd, DTS-HD Master Audio, DTS: X and Dolby ATMOS, are designed for multichannel systems, so if you plan to use the full potential of these technologies, then forward. If your space is limited, or if you simply prefer to have less speakers, you can still enjoy excellent sound quality (compared to the built-in speakers of your TV), using only two small speakers connected to your receiver.
In order to reveal the potential of the receiver in home movies to it, you need to connect at least five columns and subwoofer.
Wired and wireless communication
Just a few years ago it seemed that manufacturers try to stuff as many audio and video inputs in their AV receivers. As the HDMI interface began to be distributed, the connection is slightly simplified, and at the moment even the AV-AV-receivers have five or more HDMI inputs. Although the equipment is good, there is no need to overestimate the number of inputs that your new AV receiver has more important to evaluate the needs of your system. For example, if the AV receiver has four HDMI inputs, but you have only two HDMI sources, this AV receiver will satisfy your needs in this type of connection, while at the same time giving you a reasonable number of digital inputs for growth. However, if you look like me and you have more components than the time to enjoy, you need so much inputs as you can get.
Now even the AV averages of the middle level have five or more HDMI entries and a wireless connection to a Wi-Fi home network or directly to a mobile device via Bluetooth
If you have content stored on mobile devices, such as smartphones or tablets, AV receiver with Bluetooth and AirPlay support will allow you to transfer music over a wireless network from your similarly equipped devices. Some AV receivers also offer integrated Wi-Fi and Ethernet connections, as well as access to paid multimedia streaming services with millions of music tracks. Thanks to the DLNA technology, you can access the local content of your computer and network servers. DLNA is a great way to unify your audio and video content and reproduce it from a centralized point (for example, the receiver in the living room). One of the main advantages of wireless and network music sources is that they can provide listeners with many listening options, while at the same time reducing the number of physical devices connected to the AV receiver.
Automatic setting and calibration of speakers
Another important function of the AV receivers of the home theater is the built-in system setting and loudspeaker calibration. There are a number of variations of this technology, which manufacturers of receiver use, the most successful of them are the technology from the Audyssey laboratory, but ultimately all these systems are aimed at achieving the same: setting the speakers for optimal performance depending on the features of the room where they are at Minimum effort from the end user. Receivers equipped with this feature are usually equipped with a calibration microphone. After connecting the microphone, the AV receiver will guide you through the process of placing this microphone in one or several places in your listening room and makes the necessary adjustments to optimize the speaker sound. The level of automatic adjustment depends on how complex methods of calibrating your AV receiver. Such technologies must be smart and convenient, so you do not interfere in the AV receiver calibration process - it is fully automated. "Warm lamp audiophiles" with a thin rumor can bypass this process and, if necessary, do all adjustments manually.
The AV receiver will hold you through the process of placing the calibration microphone in one or several places of your room and makes the necessary adjustments to optimize the speaker sound.
How to connect the receiver to tv
Since high-definition technology continues to pack as many pixels as possible in televisions, it is necessary that your receiver can keep up with your video processing needs. If you plan to connect all video sources to your receiving, you need to make sure that it is compatible with the devices and the desired resolution. If you have video sources 4K, your AV receiver must be able to support 4K to accurately transmit these video signals. It also applies to other video resolutions and signals such as 1080p and 3D. Fortunately, many modern AV receivers with HDMI support correspond to this task. Having done another step, some AV receivers use video processing capabilities that can improve the quality of low-resolution video sources to improve playback on high definition TV. Although this technology does not turn your old VHS cassettes with a resolution of 480i in the image with 4K permit, still the image will be improved as possible for optimal viewing on the big screen. In addition to permission, there are other video processing considerations, such as HDMI CEC, which allow you to automate the joint on and turning off the devices and switching input signals and Mobile High-Definition Link (MHL), which allows you to duplicate the smartphone screen on the TV and charge compatible Portable devices.
Sound Transmission from TV Nowadays, smart TVs are found everywhere, and the ease of use of applications such as YouTube, Netflix and many other built-in TV, set a new question: How to pass the sound from the TV to an AV receiver? Use input HDMI Earc. or HDMI Arc (Audio Return Channel). This HDMI connection feature provides a double-sided data stream, so you can transmit video through the receiver from your source device to your TV or transmit audio from your TV to an AV receiver through the same HDMI cable that already connects the receiver and TV. Previously, the sound from TV was transferred to an AV receiver using an optical cable or RCA cables.
Our detailed guide on how to connect the TV to the AV receiver.
HDMI input with Arc (sound return channel) Allows you to send sound from TV back to AV receiver if ARC-compatible receiver. Thus, you do not need to make a separate audio disciplement between the TV and the receiver.
Receiver as a multi-controller controller
It seems that these days remain motionless and listen to music in one place - this is a luxury that few of us can afford. If you, a person who walks around his house right now, reading this article on a smartphone or tablet, you will be glad to hear that many AV receivers can match your active lifestyle. In AV receivers, additional rooms on which they can transmit sound are called "zones", and they allow you to connect additional speakers to your system to play one source or different sources in several rooms. In some cases, you may need to connect an external amplifier to work on the second zone, but many AV receivers, as a rule, medium and highest levels offer the output of two channels of the built-in amplifier to the second and even third zone. This feature allows the AV receiver to distribute the sound to other parts of your home, and not limited to one room.
Acoustic outputs AV receiver not involved in the home theater can be used to sound a neighboring room or bathroom.
Wireless Multi Music
Many modern receivers work with musical multicam platforms that allow you to broadcast music on compatible wireless columns that you are located all over the house. You can create different zones and manage what plays in each room using the application on your phone or via voice commands.
