Features

Music center. Music centers are stationary audio systems, including a player, amplifier and acoustics; Their distinctive feature is the speakers, made separately from the main unit. Some models may provide mounts for installing speakers on the main unit, but these mounts are quick-release, and the length of the wires allows you to place the speakers separately.

- Minisystem. Minisystems are relatively small devices made in one-piece housings; Despite their small size, they are usually designed for stationary use, although they may have independent power supplies (see below). The functionality of mini-systems can be different: some models, in fact, are speakers with slightly expanded capabilities, in others these capabilities can be comparable to full-fledged music centers and even have wireless charging.

Radio tape recorder. The radios have a distinctive design reminiscent of cassette recorders; and some of them are even capable of working with cassettes, see "Media". Like the music centers described above, such devices have everything you need for listening - a player, an amplifier and acoustics; however, the speakers are made non-removable, and the functionality of radio tape recorders is usually more modest. On the other hand, such models are portable and can even be used to play music on the go - almost...mandatory features of radio tape recorders are the presence of a handle for transportation and the ability to be autonomously powered (see below) from replaceable batteries.

— Floor system. The purpose of audio systems of this type is already clear from the name: they are initially designed for installation on the floor. This installation allows you to create fairly large devices with powerful acoustics; in fact, most floor-standing audio systems are actually a set of speakers with a built-in player. However, there are also quite compact models of this type that allow desktop or wall installation with the stand disconnected.

- For parties. Audio systems for organizing incendiary musical parties with friends and family. Such models are capable of sounding a vast space both indoors and on the street dance floor. Often, audio systems for parties are complemented by built-in lighting effects to create a disco atmosphere; microphones can also be connected to them, which karaoke lovers will appreciate. Alternative names for such audio systems are Party speaker or PartyBox.

For musicians. Advanced speakers with good sound quality are special for musicians who give performances on the street or participate in outdoor events. Such models are not intended for full-fledged concerts, but rather for “live” performances in public places. Audio systems often include the ability to connect musical instruments, and they are often equipped with a suitcase-type handle for ease of carrying the equipment.

— Smart speaker. Audio systems in the form of relatively small single speakers with “smart” control electronics. For such devices, four key features can be distinguished: Internet connection (usually via Wi-Fi), synchronization with a smartphone or tablet (usually the same), support for voice commands and advanced functionality. In fact, smart speakers are not classic audio systems, but universal “assistants” with speakers for playing music; and the voice control capabilities in them go far beyond the “musical” functions. Thus, many models allow you to set a timer or alarm clock on a smartphone, control smart home components, get help on a variety of requests, etc. At the same time, contextual recognition of commands is often supported, with the ability to process complex requests like “put on the band I listened to yesterday In the evening".

Number of channels

The maximum number of audio channels that the audio system can reproduce through its own acoustics.

1.0. One channel of audio allows only monophonic sound — enough to hear the sound, but not providing a surround effect. The advantage of this option is compactness, because For normal operation, it is enough to equip the device with one speaker. The single-channel format is found mainly in inexpensive models, as well as in the most compact audio systems, where small size is more important than "fancy" sound.

2.0. Two channels is the minimum required to play stereo sound. This format already allows you to achieve a sense of spaciousness without requiring too many speakers and complicating the entire system. Therefore, he is very popular.

2.1. Modification of the 2.0 format described above, supplemented by a subwoofer — a specialized speaker for low frequencies. The use of a subwoofer improves sound quality by delivering rich bass sound.

2.2. A further extension of the 2.1 format described above, providing for the presence of two subwoofers — this improves the reliability of the transmission of low frequencies.

— 3.1. An extended version of the 2.1 standard, in which two classic stereo speakers are complemented not only by a subwoofer, bu...t also by a third, centre speaker. This allows you to improve the sound quality — in particular, due to a richer surround sound.

Note that 2.0 models that do not have their own subwoofer may be equipped with a subwoofer output (see below).

System power

The total sound power provided by the audio system at maximum volume, in other words, the total power of all the speakers provided by the device (including the subwoofer).

The higher the power, the louder the system will sound and the larger the area it can cover. On the other hand, high power significantly affects the price, dimensions, weight and power consumption of the device. In addition, when evaluating and comparing according to this indicator, it is worth considering some nuances. Firstly, some manufacturers go to the trick and give in the characteristics not the average, but the peak sound power; such numbers can be quite impressive, but they have very little to do with real loudness. So if it seems to you that the claimed power is too high, it's ok to clarify what exactly is meant in this case. Secondly, when comparing, it is worth considering the presence of a subwoofer — it plays an auxiliary role, but it can account for more than half of the total system power. Because of this, for equal total power, a device with a subwoofer may be quieter than a model without a subwoofer: for example, a 2.0 40W system will have 20W per main channel, while a 2.1 40W model may have 20W per subwoofer, and only 10 watts for the main speakers.

Number of bands

The number of distinct frequency ranges (bands) into which sound is divided when played through the acoustics of an audio system. For each such band, a separate speaker is provided, and sometimes several.

The simplest option provides 1 lane; it is very popular in modern audio systems, because. requires a minimum number of speakers, and the sound quality can be quite good. More advanced options provide 2-3 bands (low and high frequencies, or bass, treble and medium), and in high-end models, the number of bands can be up to five. Note that, in addition to integers, models are also produced with a fractional number of stripes — for example, 2.5 or 3.5. This marking indicates the presence in the design of a speaker responsible for two bands at once: for example, model 2.5 has separate speakers for bass and treble plus a combined bass + midrange (similar in design to bass, but also loaded with mid frequencies).

Anyway, the abundance of bands, usually, indicates a high class of acoustics: the more separate frequency ranges, the narrower the specialization of each speaker, the more accurately it is able to reproduce its part of the signal, and the more complex the system is.

Passive emitter

A passive radiator can be simply described as a low-frequency speaker that does not have its own reproducing system (coil with magnet). It is driven by pressure fluctuations created by active drivers and acts as a resonator to deliver deep, rich bass—especially useful for systems that do not include a subwoofer. At the same time, unlike phase inverters, passive radiators do not generate additional noise.

Bass Boost

Bass boost function for powerful and rich bass. Often implemented as a single button, with which you can actually "turn the bass on and off." This is more convenient than adjusting the low frequencies using the equalizer; in addition, various special technologies can be used to enhance the bass.

Interfaces

Airplay. AirPlay technology was developed by Apple. It is based on Wi-Fi and is used to wirelessly broadcast content from Apple devices to external audio systems. Thus, this function is useful for those who want to connect an iPhone or iPod touch to the audio system, but do not want to fiddle with wires; however, it is possible to connect via AirPlay and other devices - for example, a PC with iTunes and a Wi-Fi module installed.

Airplay 2. The second generation of the AirPlay technology described above, introduced in 2018. Among the main innovations of this version is support for the "multi-room" format, that is, the simultaneous transmission of several audio signals to different compatible devices installed in different places. In this way, you can, for example, turn on the radio broadcast of a news programme in the living room, relaxing music in the bedroom, etc. In addition, AirPlay 2 received a number of other improvements - improved buffering, the ability to stream to stereo speakers, as well as support for voice control through Siri.

Chromecast. The original name is Google Cast. A technology for broadcasting content to external devices developed by Google. Allows you to transmit an audio signal from a PC or mobile device to the audio system, broadcasting is standardly carried out via Wi-Fi, while the receiver and signal source must be...in the same Wi-Fi network (Chromecast media players are an exception). Note that in signal sources (smartphones, tablets, PCs, etc.), Chromecast is implemented at the level of individual applications. For example, at the time of its creation, this feature was available, among others, in the YouTube and Netflix apps for Android and iOS, as well as in the web versions of these apps for Chrome. Thanks to this format, this technology is extremely widespread in our time, and the ability to connect a particular gadget to an audio system with a Chromecast is usually limited to the ability to install appropriate applications on this gadget.

— DLNA. DLNA (Digital Living Network Alliance) is a standard that allows you to combine various types of home electronics and home appliances into a single network for content sharing and management. In the case of audio systems, DLNA can be used, for example, to play music from a computer disk connected to such a network, broadcast sound to a device installed in another room (for example, an amplifier), etc. Connection to DLNA can be carried out both wired and wirelessly (according to the Wi-Fi standard), and the compatibility of devices does not depend on their manufacturers - the only condition is compliance with the DLNA standard.

-LAN. Standard interface for wired communication to local computer networks based on RJ-45 connector. Its presence allows you to use various network features such as Internet radio (see "Advanced") or DLNA (see above). Compared to another network interface - Wi-Fi - LAN is less convenient due to the presence of wires, but it is more reliable and provides a higher actual data transfer rate.

- WiFi. The presence of a Wi-Fi wireless module in the design of the audio system. This technology is used both in computer networks and for direct communication of various devices with each other; its "range" is enough to work within residential premises, even through walls. In this case, Wi-Fi can be used to work with network features such as Internet radio or DLNA(see above). At the same time, this option is more convenient than wired LAN, due to the absence of actual wires. In addition, support for this technology is a prerequisite for using the AirPlay and Chromecast features (see above); and in some devices, Wi-Fi even allows you to connect smartphones, tablets and other gadgets as remote controls.

One of the most modern and fastest standards of this wireless communication technology is Wi-Fi 5. The 802.11ac version uses the 5 GHz band (less crowded and more less noise-resistant than 2.4 GHz), providing speeds of up to 1.69 Gbps per antenna and up to 6.77 Gbps with multiple antennas.

Bluetooth. Direct wireless communication technology between different devices. One of the most popular ways to use Bluetooth in audio systems is to work with an audio signal, primarily broadcasting sound to wireless headphones or speakers; and some models also provide the ability to connect a smartphone, tablet or other device and use the audio system as an external Bluetooth speaker. True, it should be borne in mind that initially Bluetooth is noticeably inferior to a wired communication in terms of sound quality; however, in our time, this shortcoming is often compensated by the use of one or another version of the aptX codec(see below).
In addition, other options for using Bluetooth may be provided - for example, file sharing between the built-in memory and the same smartphone, or remote control via an application. They are not mandatory for modern audio systems, but with the development of technology they are becoming more common.

In modern audio systems, the Bluetooth v 5 standard is most often used. Its important innovation is the expansion of the capabilities of the BLE (“Bluetooth Low Energy”) mode: if necessary, the device can increase the range by reducing the speed, or speed up transmission at the cost of reducing the range. In addition, a number of improvements have been introduced regarding the simultaneous operation of several connected devices.

- Support for aptX. Support for audio system aptX - a codec designed to improve the quality of sound transmitted via Bluetooth. Accordingly, this function automatically means the presence of a built-in Bluetooth module (see above). The need to use special technologies is due to the fact that in the original Bluetooth format compresses the audio signal very strongly, which significantly affects the final sound quality. aptX technology is designed to remedy the situation: according to the creators, it provides sound purity, "comparable to Audio CD (16-bit / 44.1kHz)" and almost as good as a wired communication. This is often enough even for comfortable listening to lossless formats, not to mention MP3 and other popular compressed formats. Of course, in order to use aptX, the signal source must also support it.

- Support for aptX HD. Support for the aptX HD codec by the audio system, an improved and updated version of the aptX described above. This version claims sound clarity comparable to Hi-Res (24-bit/48kHz) audio material; this allows you to comfortably listen not only to MP3, but also to lossless formats and even uncompressed audio materials. On the other hand, aptX HD support is quite expensive, and its advantages over the original aptX become noticeable only on very high-quality audio materials, for which consumer audio systems are rarely used. Therefore, this function has not received much distribution.

AAC. A codec used primarily in Apple portable devices to improve sound transmitted via Bluetooth. In this sense, it is similar to aptX (see the corresponding paragraphs), but is noticeably inferior to it in terms of capabilities: if the sound of aptX is compared with Audio CD, then AAC is at the level of an average quality MP3 file. However, for listening to the same MP3s, this is quite enough; the difference becomes noticeable only on more advanced formats.

LDAC. Sony's proprietary Bluetooth codec. It surpasses even aptX HD in terms of bandwidth and potential sound quality, providing performance at the Hi-Res level of 24-bit/96kHz audio; there is even an opinion that this is the maximum quality that it makes sense to provide in wireless headphones - further improvement will simply be imperceptible to the human ear.

- Network audio streaming. The ability of the audio system to work with network streaming (streaming) audio services like Deezer, Spotify, Tidal, etc. Such services are designed to broadcast content (in this case, mostly music) over the Internet; in this case, the files being played are not stored in the audio system, but are played directly from the corresponding resource on the World Wide Web. Nowadays, there are many streaming services that differ in the range of music and access conditions; a specific list of supported services should be specified separately. However, in any case, the main advantages of online streaming can be called an extensive selection of content and almost instant access to the desired composition; some services can also act as a radio, automatically selecting music according to the manufacturer's preferences.

- Speakerphone. Ability to use the device as a hands-free system for a mobile phone. In this mode, the audio system is connected to the device, most often via Bluetooth (see above), and the voice of the subscriber at the other end of the line is output not to the phone, but to the speakers of the audio system. This is often more comfortable than holding the phone to your ear; in addition, the speakerphone is useful if several people need to participate in a conversation.

- NFC chip. NFC is a short-range wireless technology (about 10 cm). In audio systems, NFC is mainly used to facilitate communication using the Wi-Fi or Bluetooth standard (see above). With this chip, you can simply bring an external NFC-compatible device to the audio system and confirm the communication - it's easier than manually configuring settings.

- Docking station for Android. The presence of a docking station for connecting portable electronics (primarily smartphones) based on the Android operating system. In fact, the dock is a socket-stand, supplemented with a special plug; thanks to this, it not only provides a communication, but also allows you to install an external device directly on the audio system, which is quite convenient. We also note that such a communication often provides additional features - for example, controlling the player on a smartphone from the audio system remote control. However, when choosing a model with this function, it should be borne in mind that Android devices are very numerous and diverse; in practice, this means that before buying it makes sense to make sure that your gadget is compatible with the audio system.

More features

Omnidirectional sound. As the name implies, audio systems with this feature radiate sound evenly in all directions, covering a space of 360°. Thus, the device can be installed in the centre of the room and evenly “fill” it with sound, which will be clearly perceived at any point. On the other hand, an omnidirectional system usually sounds 1.0 (mono); the design may include various tricks to ensure surround sound, but these still in most cases do not reach full stereo.

Voice assistant. Audio support for voice assistant. The most popular nowadays are such assistants: However, other solutions are also possible. Anyway, it is worth noting that this is not about the function of the audio system itself, but about compatibility with smartphones, tablets and other gadgets that have their own voice assistants. Thus, to use the voice assistant, you will have to connect the audio system to an external device. On the other hand, the capabilities of such assistants are usually more extensive than those of built-in voice control systems(see below); advanced features are often supported, such as natural speech recognition with complex queries (“Play the last album of the band … that I listened...to”), weather forecast, sports scores, etc. Of course, the specific set of supported commands and languages \u200b\u200bcan be different — depending on the voice assistant and its version.

— Voice control. A feature that is virtually mandatory for smart speakers (see "Intended Use") and hardly found in other types of audio systems. As the name implies, this control allows you to control the device using voice commands. It differs from the voice assistant (see the relevant paragraph) in that in this case we are talking about the simplest commands related to the main functionality of the audio system — for example, "Stop", "Continue", "Next track", etc. It is worth having in mind that voice control is almost guaranteed to support English, but the ability to recognize other languages should be specified separately.

— Smartphone control. The ability to control the audio system from a smartphone, tablet or other gadget with a special application installed on it. Usually, the connection is made via Wi-Fi (see "Interfaces"). The convenience of this function lies not only in the fact that you can control the system from a distance — the application is often more convenient and provides more options than the controls on the radio itself.

— Multiroom support. Device support for Multiroom technology. This technology allows you to create a single wireless network in the house from several speakers located in different rooms, and simultaneously play music in all these rooms. The specific features of such networks in different models may be different, they should be specified separately. So, some devices use a Bluetooth connection, others use Wi-Fi (directly or via a local network). In some cases, the control speaker broadcasts sound to all the others, and the same music plays throughout the house, in others, the speakers are “equal”, and different tracks can be turned on simultaneously in different rooms. Some audio systems require an external sound source (smartphone, tablet, etc.), others are capable of playing the role of a player themselves, including for streaming Internet services.

— Synchronization of speakers. The model supports the ability to synchronize the operation of several speakers connected to one signal source. This solution allows you to realize truly stereo sound, improve the quality and power of sound reproduction, as well as expand the stereo panorama. The only thing is that both speakers must support the appropriate connection type. Different brands may have their own speaker interconnection technologies (JBL Connect, JBL PartyBoost, Sony Party Chain), or maybe a universal TWS.

— Karaoke. A popular entertainment that allows users to sing their favorite songs to the backing track (musical accompaniment with the original vocals cut out) — in such a way that the vocals superimposed on the backing track are played through the acoustics of the audio system. This feature requires at least one microphone input.

— Karaoke Mix. An extended version of karaoke (see above), which provides various additional features — for example, performance evaluation in points, singing competitions, etc. Usually, it allows you to connect two microphones already.

— Internet radio. Ability to listen to Internet radio stations on the audio system. In general, such broadcasting is similar to conventional broadcasting, however, it is carried out not through the radio, but through the World Wide Web, which provides some additional features. So, Internet broadcasting has no restrictions on the range and ranges, allows you to listen to programs from any country and in any language; and the list of broadcasters is extremely extensive, among them there are both traditional radio stations duplicating their programs on the Internet, and specific, purely network projects. The presence of this function assumes support for at least one network interface — Wi-Fi or LAN (see "Interfaces").

— Recording to a USB drive. The ability of the audio system to record to an external USB device — for example, a USB flash drive. In this way, you can record your favorite radio programs from a conventional tuner or Internet station (see above), copy music from optical discs, etc.; Specific USB recording capabilities vary by audio system model.

— Clock. Ordinary clock — a device for displaying time, most often in the form of numbers on the display. Sometimes these hours are the most convenient. In addition, this function is necessary for some other features — primarily the alarm clock (see below).

— Alarm. A classic alarm clock that sounds at a set time. It can be useful not only for wake-up calls, but also in other cases when you need to warn the user about the arrival of a certain time. A feature of this function in audio systems is that the inclusion of a specific radio station or musical composition can be used as a signal.

— Shutdown timer. A feature that allows the audio system to turn off automatically after a user-defined time. Thanks to the timer, you can, for example, turn on relaxing music to fall asleep and fall asleep peacefully — the audio system will turn off on its own.

— Nightlight. The presence in the audio system of its own built-in lamp of low power, which allows it to be used as a night lamp. A night light can be useful for both young children and adults who are uncomfortable falling asleep in complete darkness; in addition, it can come in handy in situations where you have to get up in the middle of the night or early in the morning, before sunrise — at least with the light from the nightlight, it's easier to get to the main switch.

Inputs

RCA. The RCA interface uses coaxial cables with characteristic "tulip" plugs and corresponding connectors. It can be used to transfer different types of data, however, in this case, it means connecting the audio signal from the preamplifier in analogue format, one channel of audio per connector. RCA is widely used in modern audio technology, but its resistance to interference is very limited.

Mini-Jack(3.5 mm). Standard connector for most modern portable audio equipment. In audio systems, it is mainly used to connect such equipment — primarily pocket media players. It uses analogue signal transmission, while the resistance to interference, like RCA, is not high, and the quality may even be lower due to the fact that both channels of stereo sound are transmitted over the same cable.

Coaxial S / P-DIF. An electrical version of the S / P-DIF standard, using a coaxial cable with a “tulip” connector for signal transmission. Do not confuse this interface with the analogue RCA described above — despite the identity of the connectors, these standards are fundamentally different: "coaxial" works in digital format and even multi-channel audio can be transmitted over a single cable. Compared to optical S/P-DIF, this interface is less resistant to interference, but more reliable because electrical cables are not as delicate.

— Optical. One...of the varieties of the S / P-DIF standard is, along with the coaxial one described above. In this case, the signal is transmitted via a TOSLINK fibre optic cable. The main advantage of this interface is its complete insensitivity to electrical interference, while its capabilities are sufficient even to work with multi-channel audio. Among the shortcomings, it is worth noting the high price of connecting cables, as well as the need for careful handling of them.

— Under the microphone. Input for connecting a microphone to an audio system; can use different types of connectors (3.5 mm mini-Jack, 6.35 mm Jack, etc.). This function is mandatory for models with karaoke (see "Advanced"), but can be used for other purposes.

Instrumental. Connectors used to connect musical instruments (acoustic or bass guitars, keyboards, etc.). Most often they are made in the form of 6.35 mm Jack format sockets. The audio signal from pickups has its own specific characteristics, so the instrument input typically features a higher input level and special impedance matching to ensure optimal sound quality.
