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.

Virtual surround sound

The projector supports the virtual surround function.

The purpose of this feature is that due to special sound settings and the reflection of sound beams from the walls of the room, the listener hears more channels than are actually available in the projector (see "Audio Format"). For example, a 3.1 system with virtual surround sound can produce sound similar to 5.1 surround sound. This allows you to achieve the effect of "immersion" in sound without increasing the number of channels and the cost of the projector. On the other hand, the reliability of such sound is usually noticeably worse than that of real surround sound, and the overall quality is highly dependent on the characteristics of a particular room.

Note that the virtual surround function is specified for 2.0, 2.1, 3.0, 3.1 format systems. In more advanced multi-channel systems, there are a priori additional channels for reproducing surround sound.

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.).

Inputs

USB A. In this case, we mean a USB connector that allows you to connect external drives (flash drives, hard drives) to the projector and play content directly from them. At the same time, models with video outputs (see below) can often work as a media centre, outputting the video signal to a TV or other external display.

mini-Jack (3.5 mm). By itself, the 3.5 mm plug can be used in different types of interfaces; in this case, it means a linear audio input with a mini-Jack socket. This input is mainly used to connect portable audio equipment (players, smartphones) to the sound projector.

RCA. Technically, RCA (colloquially "tulip") is a type of connector that can be used in different interfaces. However, the term "RCA input" is used to refer only to line inputs for connecting an analogue signal in stereo format. Note that this input consists of two sockets for RCA cables, because. Only one channel of sound can be transmitted through one cable.

Optical. Connector for digital audio signal connection via TOSLINK fibre optic cable. This interface allows for multi-channel audio transmission and is virtually immune to electrical interference; its disadvantage is the fragility of the cable.

Coaxial S / P-DIF. A connector for connecting a digital audio signal via an elect...rical cable with an RCA connector (not to be confused with linear RCA, described above). Similar to the optical input described above, in particular, the ability to transmit multi-channel audio through a single connector. At the same time, a coaxial cable, on the one hand, is not so delicate, and on the other hand, it is sensitive to electrical interference (therefore, it is advisable to use a special shielded wire for such a connection).

— Composite. In this case, we do not mean a full-format composite interface of three connectors that allows you to transmit audio and video signals, but only one connector for working with video. And since sound projectors don't display images, the composite input is used to send video through the projector to another device, such as a TV. The composite video interface does not allow working with HD and is not of high quality; on the other hand, it is widespread and can even be used to work with frankly outdated video equipment. Typically this input uses a yellow RCA plug.

— Component. An input designed to receive an analogue video signal for further transmission to another device — a TV, video projector, etc. This connection typically uses three RCA connectors, each carrying a different video component (hence the name). Due to this, the component interface has good bandwidth and picture quality, it allows you to work with HD and is considered the most advanced modern analogue video standard.

— IR control input. Connector for connecting an external infrared remote control receiver. When properly placed, such a receiver will allow you to use the remote control even in places where the signal from the remote control cannot reach the main (built-in) sensor — for example, in another room. Note that the role of the receiver can be played not only by a specialized device, but also by another component of the audio system — for example, an amplifier with an IR control output.

HDMI input

The number of HDMI inputs in the design of the sound projector.

HDMI is the most popular modern interface for working with HD content, it allows you to transmit high-definition video simultaneously with multi-channel audio over a single cable. Having multiple inputs allows you to keep multiple signal sources connected to the projector at the same time and select the source from the remote without fiddling with reconnecting wires.

Number of speakers

The total number of speakers installed in the sound projector housing (external subwoofer is not taken into account in this calculation).

Given the same audio format (see above), more speakers typically provide greater fidelity and more precise localization of individual sound sources. This is especially true for models with virtual surround sound.

Tweeter size

The diameter of the tweeters ("tweeters") installed in the sound projector. The larger the speaker diameter, the higher its power can be, but the lower the operating range. Therefore, tweeters, usually, are small in size, and the required power can be provided by their total number (see above).

Woofer size (LF/MF)

The diameter of the woofers (or combined woofers, in two-way systems) of the speakers installed in the sound projector. For speakers in this range, large size is especially important - it is the cones of large diameter that work best at low frequencies, while providing good power. It is believed that for a head operating in the subwoofer format, a size of at least 200 mm is desirable. But the low-frequency speakers of the general range can be relatively small.

Full range speaker size

The diameter of the full range speakers installed in the sound projector. Broadband speakers are called speakers responsible for reproducing the entire main frequency range — from bass (with the exception of the lowest) to treble. They are used in single-lane projectors. The general rule of acoustics says that the larger the speaker, the higher its power can be and the lower its operating frequencies. Accordingly, the size of full range speakers is usually relatively small.
