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.

Speaker synchronization

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

More features

Omnidirectional sound. As the name suggests, audio systems with this feature emit sound evenly in all directions, covering a 360° space. Thus, the device can be installed in the center 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 in 1.0 format (mono); the design may include various tricks to ensure surround sound, but such systems still fall short of full-fledged stereo in most cases.

Voice assistant. Support of the audio system of the voice assistant. The most popular assistants nowadays are: However, other solutions can also be used. In any case, it is worth noting that we are not talking 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 functions are often supported, such as natural speech recognition with complex queries (“Play the latest album of the band ... that I listened to”), voicing the weather forecast, sports results, etc. Of course, the specific set of supported commands and languages may vary - depending on the voice assistant and its version.

— Voice control. A function that is practically mandatory for smart speakers (see “Purpose”) and is almost never found in other types of audio systems. As the name suggests, this control allows you to control the device using voice commands. It differs from the voice assistant (see the corresponding section) 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 keeping in mind that voice control almost certainly supports English, but the ability to recognize other languages should be clarified separately.

— Mobile application. The ability to control the audio system from a smartphone, tablet or other gadget with a special application installed on it. As a rule, the connection is via Wi-Fi (see "Interfaces"). The convenience of this function is not only that the system can be controlled remotely - the application is often more convenient and provides more options than the controls on the radio itself.

— Multiroom support. The device supports Multiroom technology. This technology allows you to create a single wireless network in your home from several speakers placed in different rooms, and simultaneously play music in all of these rooms. The specific features of such networks may be different in different models, they should be clarified separately. So, some devices use a Bluetooth connection, others - via 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 played 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.

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

Karaoke Mix. An extended version of karaoke (see above), providing various additional options — for example, assessment of performance skills in points, singing competitions, etc. As a rule, it allows you to connect two microphones.

— Internet radio. The ability to listen to Internet radio stations on the audio system. In general, such broadcasting is similar to conventional broadcasting, but it is carried out not via radio, but via the World Wide Web, which provides some additional opportunities. Thus, Internet broadcasting has no restrictions on range and range, 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 broadcasts 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 to operate the audio system in recording mode to an external USB device, such as a flash drive. This allows you to record your favorite radio programs from a regular tuner or Internet station (see above), copy music from optical discs, etc.; specific USB recording capabilities depend on the audio system model.

— Clock. A regular clock is a device for displaying time, most often in the form of numbers on a display. Sometimes it is precisely such a clock that turns out to be the most convenient. In addition, this function is necessary for some other features — primarily an alarm clock (see below).

— Alarm clock. A classic alarm clock that gives a signal at a set time. It can be useful not only for waking up, but also in other cases when it is necessary to warn the user about the onset of a certain time. The peculiarity of this function in audio systems is that the signal can be the switching on of a certain radio station or musical composition.

LCD display

The presence in the audio system of its own LCD display. Such displays may have different characteristics: in some models, these are the simplest indicators in which symbols are made up of separate luminous fragments (similar to how numbers are made up of separate “sticks” in the simplest electronic watch); in others — full-fledged matrices with an image formed from pixels. However, anyway, the display makes the control of the audio system more convenient and intuitive, because. can display various additional information — the selected signal source, track name, RDS data (see above), equalizer settings, error messages and much more.

Lighting effects

The presence in the audio system of the function of light effects. Usually, this is the backlight of the speakers and/or the front panel, which can change brightness and colour, blink, etc.; the rhythm of work can be independent or synchronized with the track being played in the light music mode. This function practically does not affect the main functionality of the device, its purpose is purely decorative.

Touch control

The presence of touch control in the audio system.

Sensors are considered more advanced controls than buttons, rotary knobs, etc. Firstly, they give the device a stylish and technological appearance. Secondly, touch panels do not have unnecessary protruding parts, so they resist dirt well and are easy to clean. Thirdly, such control is purely "to the touch" pleasant for many users: the sensor is triggered by a light touch, you do not need to press it like a button. On the other hand, this feature significantly affects the cost of the audio system.

Microphone included

Microphone included. This equipment allows out of the box to ensure complete readiness for all kinds of events from light background voice acting to wedding feasts with a toastmaster and competitions.

USB for charging the audio system

The presence of a standard USB connector for charging the audio system.
– microUSB. One of the miniature versions of the USB connector, still popular in portable gadgets, despite the emergence of a more advanced USB-C. It has relatively limited capabilities (in particular, it is inferior to USB-C in terms of the maximum possible charging power), but this moment is rarely important. At the same time, there are many cables and chargers for microUSB.

– USB-C. A relatively new type of USB connector, actively gaining momentum. Like microUSB, it is small in size, but has a more convenient double sided design and advanced features, such as the ability to transmit higher power, which has a beneficial effect on charging time.
