Audio format

The audio format produced by a sound projector is actually the largest number of individual audio channels supported by the device. Note that in this case we are talking about the number of real channels, that is, channels for each of which at least one speaker is allocated; Models that support virtual surround sound can give the listener the impression of more channels than there actually are (see below for more details).

The sound format is indicated by two or three numbers separated by a dot. The first indicates the number of main channels, the second - the number of subwoofers, the third - the number of additional vertical radiators. For example, 2.1 format corresponds to stereo sound (2.0) supplemented by a subwoofer. And the conditional 3.1.2 format includes left, right and center channels, a subwoofer, left and right vertical speakers.

Sound projectors that support a more advanced sound format than 3.1 are designated in our catalog as multi-channel. The classic multichannel audio format is 5.1, but there are other options. In any case, a large number of real channels contributes to the fidelity of the reproduced sound and simplifies setup compared to virtual surround sound systems, but is also more expensive.

The most common sound formats are: 2.0, 2.1, 3.0, 3.1, 4.1, 5.1, 5.1.2, 7.1.

Mount type

Regular way to install a sound projector.

Shelf. The installation itself on the shelf is extremely simple and requires a minimum of effort. However, in the absence of a shelf in a suitable place, you will either have to hang it there (for which, most likely, you will need to drill the walls), or install the projector "where possible" and try to adjust the sound as needed (and the success of such a setup is not guaranteed).

Wall mounted. Projectors equipped with wall mounts, usually in the form of brackets or notches in the chassis for nails, screws, or other wall-mounted mounts. This option is good because you can choose the installation location of the projector at your discretion, not limited to the presence of shelves — the main thing is that there is a free wall.

— Shelf / wall. Projectors that can be either shelf-mounted or wall-mounted. Both of these options are described above. Here we note that the installation method determines not only the design of the case, but also some features of the sound produced by the projector. In fact, this means that a “pure wall” projector, when installed on a shelf, will not be able to produce sound of proper quality, even if there are no problems with the installation itself. In other words, if you need a device suitable both for a shelf and for hanging on a wall, you should choose from models for which such a possibility is direc...tly stated.

— TV Stand. In fact, such models are a variation of the shelf projectors described above, which have a flat body, so that a TV can be installed on top of such a device. This will prevent the sound projector from obscuring the controls and remote control sensor located below the screen (whereas with conventional shelf models, such problems often occur when placed on the same shelf with a TV). The disadvantage of "stands" can be called a rather large size in depth.

Rated power

The total power rating of the sound projector speakers (including subwoofer, if present).

This parameter is often used to estimate the overall sound volume of the device, but this is not entirely true. The fact is that the actual sound volume is determined mainly by the power of the main speakers of the sound projector, and the total power is the sum of this power and the power of the subwoofer. Therefore, models with the same power rating can vary markedly in actual volume: for example, a 150-watt soundbar with a 50-watt subwoofer will be louder than a 100-watt projector with a subwoofer of the same power, although in both cases the rated power will be equal to 200 watts.

Summing up, we can say that it is possible to evaluate the volume by rated power only if the sound projector is not equipped with a subwoofer — in such models, the rated power is equal to the power of the main speakers. In other cases, it is worth focus on the power of the soundbar and the power of the subwoofer directly stated in the characteristics (see below for both).

Audio decoders

A decoder can be broadly described as a standard in which digital audio (often multi-channel) is recorded. For normal playback of such sound, it is necessary that the corresponding decoder is supported by the device. The first signs of multi-channel decoding were Dolby Digital and DTS, gradually improving and introducing new features. The final stage for 2020 is Dolby Atmos and DTS X decoders.

Dolby Atmos. A decoder that does not use a rigid distribution of sound across channels, but the processing of audio objects, due to which it can be used with almost any number of channels on a reproducing system - the sound will be divided between channels so that each audio object is heard as close as possible to its proper place. When using Dolby Atmos, in-ceiling speakers (or speakers facing the ceiling) are highly desirable. However, in extreme cases, you can do without them.

DTS X. An analogue of the Dolby Atmos described above, when the sound is distributed not through individual channels, but through audio objects. The digital signal contains information about where (according to the director's intention) the object audible to the user should be and how it should move, and the processor of the reproducing device processes this information and determines exactly how the sound should be distributed over the available channels in order to achieve the required localization. Thanks to this, D...TS X is not tied to a specific number of audio channels - there can be as many as you like, the system will automatically divide the sound into them, achieving the desired sound. Also note that this decoder allows you to separately adjust the volume of dialogues. A separate variant of DTS X is the DTS Virtual:X decoder for providing surround sound without the use of additional upward speakers on the soundbar. You can rely on just two channels and a separate subwoofer to achieve the desired DTS Virtual:X effect. A separate variation of DTS X is the DTS Virtual:X decoder to provide surround sound without the need for additional upward-firing speakers on the soundbar. DTS Virtual:X can rely on just two channels and a separate subwoofer to achieve the desired effect.

IMAX Enhanced. The IMAX Enhanced Mark of Conformity is awarded to equipment that meets the audio certification requirements of IMAX Corporation. Combined with DTS audio technology to deliver signature IMAX theater-like sound in the home. The most accurate reproduction of such audio is possible in systems with a large number of channels (5.1 or more). Note that for a fully immersive experience, IMAX Enhanced certification must also apply to video equipment for playing content (TV, projector, etc.).

Control

The ability to control the soundbar, in addition to the standard push-button from the device case, also includes control from the remote control, the TV remote control to which the acoustics are connected, through the application from a smartphone or tablet, and in some cases using a voice assistant. More details about each of them:

— Remote control. The presence in the configuration of the classic remote control on IR sensors, like those used in TVs. It can contain much more settings functions than the controls on the body of the device and, of course, makes it easier to control the soundbar.

— TV remote control (HDMI-CEC). Connecting the soundbar via the HDMI port allows you to control it via the HDMI-CEC protocol via the TV remote control. This solution will reduce the number of remotes in the room and facilitate the comfort of the settings. However, the functionality of the "non-native" remote control may be limited. In this case, the compatibility of the TV and the soundbar can be achieved using other protocols (not necessarily HDMI-CEC).

— Smartphone control. The ability to control the soundbar through the application. This makes it easier to “search” for the remote control, because the phone is always at hand. The application also has extensive settings and such control is highly likely to be supported by t...he TV, which allows you to execute absolutely any commands from your smartphone for a comfortable pastime on the TV.

— Voice assistant. This is not about the assistant built into the soundbar itself, but about compatibility with external devices that have this function (for example, with a smartphone or tablet). But even such compatibility allows you to give commands to the voice projector by voice — this is often more convenient than more traditional control methods. The specific set of supported commands and languages may vary depending on the voice assistant and its specific version. And among the most popular at the moment are Google Assistant, Apple Siri, Amazon Alexa.

Power consumption

The total power consumption of the entire system, both the sound projector itself and the external subwoofer (if present). Usually this indicator is indicated by the average power consumption at maximum volume. Note that on individual signal jumps, the actual power consumption may exceed the claimed one; in some cases (for example, when connected through a voltage stabilizer), this must be taken into account.
