Channels

The most advanced multi-channel audio format that a sound card is capable of outputting.

2. Standard stereo sound on two channels — left and right. This format allows you to provide a sense of surround sound (especially when using headphones), which is quite enough for most simple tasks. However, it noticeably loses to multi-channel sound in terms of the "immersion effect", which can be critical for demanding gamers and audiophiles.

5.1. The classic and most popular multi-channel surround sound format today: a centre channel, two front and two rear channels allow you to achieve a full-fledged “surround effect”, and a separate subwoofer channel provides rich bass sound.

7.1. The 7.1 format differs from 5.1 by the presence of two additional channels. There are several options for localizing these channels — for example, a pair of side speakers, a pair of additional speakers above the front ones, etc. Anyway, the 7.1 format provides a more reliable surround sound transmission than 5.1, but such cards are more expensive, and there is less specialized content for 7.1.

When choosing a sound card by the number of channels, it is worth considering such moments. Firstly, multi-channel options are capable of producing sound in simpler formats (for example, a 7.1 card can be used for 5.1 acoustics), and stereo sound output is support...ed by all models in general. Secondly, modern multimedia software (in particular, codecs) allows you to output multi-channel audio through a card with fewer channels — for example, play 5.1 sound through a two-channel card with stereo speakers without quality loss. Thirdly, for the full-fledged operation of multi-channel sound, you will need not only a card, but also appropriate acoustics; therefore, it makes no sense to specifically look for a multi-channel model if you plan to use exclusively stereo speakers.

More features

— Headphone Amplifier. The presence of a separate headphone amplifier in the design of the sound card. Such equipment allows at least to improve the overall sound of the “ears”, as well as to implement various additional settings for such sound (for example, a separate volume control). And some headphones — primarily high-impedance Hi-Fi models — in principle cannot be used without special amplifiers.

— External control module. The presence of an external control module in the design of the sound card. Such a module is actually a control panel with a wired connection; it doesn't give you the freedom of movement that a wireless remote control does (see below), but it's cheaper and often more convenient. So, the control module does not have to be in direct line of sight with respect to the audio card, and the length of the wire is often enough to place the device at the user's hand. However the set of adjustments placed on the external unit is usually limited to the most basic settings; however, even this, usually, is quite enough for comfortable use. In addition, the control unit often provides additional connectors for connecting headphones and a microphone. Among other things, this feature is especially convenient in games — it allows you to adjust the sound without distracting from the game itself. However, other types of sound cards can also be equipped with external modules (see "View").

— Remote control. A remote control is included with the sound card. Do not confuse this function with the external control module described above: in this case, we mean a classic wireless IR remote control, like those used in TVs. Such a device does not necessarily cover all the capabilities of the audio adapter, however, the range of functions of the remote control can be quite extensive. On the other hand, the need to control a sound card from a distance is extremely rare, and in most cases, the mentioned external module is enough for this. So models with a remote control are not widely used.

Exit to the front panel. Ability to connect an internal sound card (see "Type") to the connectors on the front panel of the PC. To do this, a special connector (or several connectors) is provided on the board, which is connected to the corresponding connector (s) using a wire. The convenience of this feature is obvious: in desktop computers, the front panel is located closest to the user, and it is to it that it is easiest to connect peripherals that involve frequent plugging and unplugging, such as headphones and microphones. Actually, connectors for such devices are most often displayed on the front panel.

RCA

The number of outputs with RCA connectors(colloquially known as "tulips") in the sound card design. Like the Jack and mini-Jack interfaces, RCA is designed to carry an analogue signal, however, only one channel can be transmitted on one cable. On the one hand, this improves the sound quality, on the other hand, two connectors are required to transmit a stereo signal instead of one. Therefore, RCA is practically not used in headphones and is very rare in "purely computer" speakers, but it is quite popular in home-class acoustic systems and can be useful if you are planning to build such a speaker based on a computer.

Separately, we note that this output should not be confused with coaxial S / P-DIF (see below): although the latter also uses an RCA jack, however, it is fundamentally different in signal format and has specific cable requirements.

Optical S/P-DIF

The number of S/P-DIF optical outputs provided in the design of the sound card.

S/P-DIF is a digital audio transmission standard, including multichannel, quite widespread in home acoustics. At the hardware level, this standard has two versions — coaxial (see below) and optical, which is discussed here. The TOSLINK fiber optic cable used for this type of connection is highly resistant to interference: electromagnetic pickups do not interact with the light pulses that transmit the signal. On the other hand, such a cable is more expensive than coaxial electrical wire and requires careful handling — strong pressure or a kink can damage the fiber.
