Brzo objašnjenje kanala surround zvuka:2.0, 2.1, 5.1, 7.1, 9.1 i više!
Ako postavljate bilo kakav sustav surround zvuka, vjerojatno ćete naići na brojke poput 2.1, 5.1, 7.1, 7.1.2, 9.1 pa čak i više od njih! Možda se pitate što su ovi čudni brojevi i što oni znače za vaš sustav kućnog kina.
Pa, ovi su brojevi vrlo važni jer opisuju konfiguraciju zvučnika sustava i u nekim slučajevima format audio signala koji se isporučuje. Oni su također važni kada razmišljate o tome vrijedi li vam surround zvuk.
Dakle, idemo brzo ući u detalje ovih različitih sustava zvučnika surround zvuka i kako se postavljaju njihovi različiti sustavi kanala.
Imajte na umu da ako tražite bežični audio sustav za svoj dom, bežični multiroom sustav kao što je Sonos ili Heos je bolji izbor. Možete pogledati našu recenziju Sonos vs Heos.
Što brojevi znače u terminologiji surround zvuka?
Prvi broj (npr. “5” u 5.1)
Prvi broj konfiguracije sustava zvučnika označava broj glavnih zvučnika u postavci surround zvuka. Kada govorimo o glavnim zvučnicima, mislimo na središnji, prednji lijevi, prednji desni i razne druge surround zvučnike. 
Moderni surround sustavi obično će imati od najmanje 2 do 9 ili čak više glavnih zvučnika.
Drugi broj (npr. “1” u 5.1)
Drugi broj konfiguracije sustava zvučnika označava broj subwoofera u postavci. U većini slučajeva, ovaj broj će biti 1, što znači da sustav ima jedan sub. 
Međutim, neke konfiguracije dodaju dodatni sabvufer za postizanje potpunijeg basa u kućnom kinu pa ćete umjesto njega vidjeti broj 2, npr. 7.2.
Treći broj (npr. “2” u 7.1.2)
Treći broj konfiguracije sustava zvučnika viđa se rjeđe i odnosi se na zvučnike visine. Ova konfiguracija označava broj "visokih" ili "gorećih" zvučnika.
Visinski zvučnici su dodatni surround zvučnici koji se obično postavljaju na strop na prednjoj strani kućnog kina. Ovi zvučnici dodaju dimenziju visine surround zvučnom polju kako bi stvorili trodimenzionalni efekt.
Za ove zvučnike strop ne bi trebao biti viši od 14 stopa, ali bi trebao biti najmanje tri stope izravno iznad lijevog i desnog glavnog prednjeg zvučnika i okrenut izravno prema slušatelju.
U većini slučajeva, većina ljudi će imati dva zvučnika okrenuta prema gore pa je ovaj treći broj često 2.
Objašnjenje surround zvučnih sustava kućnog kina:2.0 do 13.1
Sustav stereo zvučnika 2.0
2.0 sustavi zvučnika su normalni stereo uređaji, a ne surround zvuk. Ovo su najosnovniji stereo sustavi koje ćete naći u blizini. Zapravo, možete pogledati naš vodič o tome kako pretvoriti stereo u 5.1 surround zvuk.
Ovi stereo uređaji imaju 2.0 desni i lijevi stereo zvuk s dva različita kanala. Sastoje se od jednostavnog lijevog i desnog kanala (ili lijevog i desnog zvučnika).
Kažemo da su osnovni jer su isti kao vaši stari stereo sustavi. Koriste dva kanala zvučnika za razdvajanje zvukova kako bi stvorili potpuniji doživljaj.
Većina današnjih namjenskih glazbenih uređaja, od osnovnih radija do boomboxova, imat će barem stereo zvuk i stoga se mogu klasificirati kao 2.0 sustavi surround zvuka.
Prednost broj jedan postavljanja 2.0 je to što je to pristupačno postavljanje. Mnogi ljudi započinju svoja kućna kina na ovaj način jer je jeftin i jednostavan.
Postavljanje sustava zvučnika za surround zvuk 2.0
U većini slučajeva, kada ljudi postavljaju 2.0 sustav zvučnika, imat će dva zvučnika pored televizora – jedan s lijeve i jedan s desne strane.
U većini slučajeva također će ove zvučnike napajati AV prijemnik ili pojačalo. U najjednostavnijim postavama, većina ljudi će se odlučiti za aktivne zvučnike koji ne trebaju poseban izvor napajanja kako bi postavke bile jednostavne i funkcionalne. 
Jedan nedostatak 2.0 sustava je taj što nemaju odvojeni subwoofer pa bi kvaliteta basa mogla biti loša osim ako ne nabavite dobre zvučnike s napajanjem.
Budući da se ovaj sustav fokusira na zvuk sprijeda, nema ni okolnih zvučnika, tako da je 2.0 postav još uvijek prilično jednostavan. Opet, možete pogledati naš vodič o tome kako pretvoriti 2.0 stereo audio u 5.1 surround zvučne sustave.
Jedno važno razmatranje za ove jednostavne sustave je osigurati da su vaši zvučnici kompatibilni sa svim vašim uređajima od Tour TV-a do vašeg pametnog telefona i da imaju bežične mogućnosti uključujući Bluetooth.
2.1 Surround Sound sustav zvučnika
Postavljanje 2.1 sustava zvučnika korak je naprijed u odnosu na 2.0 postavljanje. U ovoj postavci imate lijevi i desni zvučnik i subwoofer.
Ako imate subwoofer u postavci, vaš će surround sustav dati bolji bas.
Postavljanje sustava zvučnika za surround zvuk 2.1
2.1 postava bit će slična 2.1 postavci sa svakim zvučnicima sa svake strane televizora. Subwoofer se obično postavlja u kut uz zid.
Međutim, to stvarno ovisi budući da je svaka soba drugačija, trebali biste pomicati subwoofer kako biste dobili potpuni učinak basa. Zapravo, mnogi su ljudi otkrili da je najbolje mjesto za njihov subwoofer iza kauča.
Mnogi ljudi danas jednostavno biraju 2.1-kanalni soundbar kako bi dobili 2.1 subwoofer u postavci. Ova postavka je odlična za svako kućno kino ako nemate sredstava za dodatne uređaje. Zapravo, preporučamo da u svom kućnom kinu koristite barem 2.1 postavku .
3.1 Surround Sound sustav zvučnika
3.1 zvučni sustav je četverokanalni zvučni sustav. Ova postavka ima tri glavna zvučnika i subwoofer.
To znači da će se sustav sastojati od lijevog, središnjeg i desnog zvučnika. 
Uz 3.1, dobit ćete dodatni središnji zvučnik u odnosu na 2.1 postavku. Ovaj središnji zvučnik odvaja audio dijalog koji je obrađen za poseban kanal. Međutim, lijevi i desni kanal ostaju različiti.
Dakle, dok središnji zvučnici reproduciraju dijalog, lijevi i desni zvučnici koristit će se za efekte, glazbu i druge stereo zvukove.
Postavljanje sustava zvučnika za surround zvuk 3.1
Uz postavku 3.1, vaši lijevi i desni zvučnici obično su postavljeni sa strane TV-a sa središnjim zvučnikom na vrhu ili ispod TV-a, a vaš subwoofer također je normalno postavljen na podu u sredini postavke.
3.1 sustavi su još uvijek relativno jednostavni i nemaju okolne zvučnike. Međutim, dodavanje središnjeg zvučnika čini dobar posao u poboljšanju kinematografskog zvuka.
Postavka 3.1 vrlo je popularna u nekim zvučnim trakama. Ove zvučne trake imaju tri zvučnika ili traku sprijeda, a čak imaju i ugrađeni subwoofer. Drugi mogu imati zaseban pod.
4.1 Surround Sound sustav zvučnika
4.1 surround zvučni sustav kućnog kina korak je naprijed u odnosu na 3.1 sustav zvučnika. To je vrlo uobičajena konfiguracija i uključuje sljedeće:
- prednji lijevi i prednji desni
- stražnji lijevi i stražnji desni
- jedan subwoofer.
To znači da je ovo petokanalna postavka, osim što ne uključuje tipični zvučnik središnjeg kanala.
5.1 Surround Sound sustav zvučnika
Sustav kućnog kina 5.1 najpopularniji je sustav kućnog kina. Nudeći pravi surround zvuk, ova konfiguracija kućnog kina postala je mjerilo za surround zvuk kućnog kina.Zašto je 5.1 surround sustav popularan?
Vidjet ćete da se 5.1 surround zvučni sustav često spominje kada budete tražili ili pregledavali proizvode kućnog kina. Evo zašto je konfiguracija 5.1 zvučnika toliko popularna:- Jednostavno: To je najjednostavniji pravi surround zvučni sustav
- Imerzivni zvuk: Ova konfiguracija nudi daleko impresivnije audio iskustvo nego bilo koji uobičajeni dvo- ili trokanalni stereo.
- Razmatranja prostora: Izvrstan je za manje prostore. 5.1 surround sustav je dovoljno dobar za surround zvuk, ali uključuje samo 5 zvučnika i sub. Ovo je dobro za manje prostore kada znate kako ih smjestiti. Pogledajte naš članak o tome kako postaviti 5.1 zvučnike u maloj prostoriji.
- Povezivost: 5.1 surround postavke vrlo su popularne i stoga nude širok raspon mogućnosti povezivanja. Na primjer, neki 5.1 sustavi mogu se čak povezati s mobilnim telefonom. Kao primjer, pogledajte ovaj vodič o tome kako spojiti svoje Philips 5.1 zvučnike na mobilni telefon.
Vidjet ćete da sustavi kućnog kina svih oblika i veličina koriste konfiguraciju 5.1 surround sustava za stvaranje izvrsnog audio iskustva.
Postavljanje 5.1 sustava zvučnika
Postavljanje 5.1 sustava zvučnika prilično je jednostavno. Ima šest kanala, koji uključuju pet glavnih zvučnika i naravno subwoofer.
Evo tipične postavke:
- Glavni govornik: Sustav obično ima tri zvučnika sprijeda, jedan s lijeve strane, jedan u sredini i jedan s desne strane TV-a.
- Subwoofer: podvodnik se obično postavlja u sredinu ili u kutove prostorije.
- Zvučnici za surround zvuk: Tu su i dva zvučnika za surround zvuk koji se obično postavljaju u stražnjem dijelu sobe – obično s obje strane kauča – jedan s lijeve i jedan s desne strane. Ovi zvučnici se također nazivaju i satelitski zvučnici. Oni se razlikuju od tipičnih zvučnika za police s kojima ste možda upoznati. Ako niste svjesni razlike, pogledajte naš članak o satelitskim u odnosu na zvučnike za police.
Međutim, imajte na umu da je ovo samo najčešća postavka, 5.1 sustav zvučnika je prilično svestran i može se konfigurirati na mnogo načina ovisno o jedinstvenim potrebama vaše prostorije za kućno kino. 
Međutim, ako imate dovoljno prostora u kućnom kinu, idealna postavka je sljedeća:
Prednji zvučnici: Prednji lijevi i prednji desni zvučnik pod kutom od 22-30 stupnjeva u odnosu na središnji zvučnik/TV
Subwoofer: Idealno bi bilo da podmornicu postavite u sredinu poda ili u jedan od kutova. Možete čak postaviti podmornicu iza kauča ako želite efekt vibracije. Međutim, sa subverterima najbolje je pomicati ih dok ne dobijete najbolju izvedbu basa.
Surround zvučnici: Zvučnike za surround zvuk treba postaviti pod kutom od 90-110 stupnjeva u odnosu na središnji zvučnik/TV.
Sustav zvučnika 5.1 toliko je popularan da ćete naći ovu konfiguraciju kompatibilnom s mnogim vrstama uređaja.
Zapravo, mnoga prijenosna i stolna računala dolaze s 5.1 zvučnom karticom i stoga se može koristiti s ovim uređajima, kao i bilo čime, od običnog DVD-a do kina i digitalnih pametnih TV-a.
6.1 Surround Sound sustav zvučnika
Konfiguracija surround zvuka kućnog kina 6.1 korak je više od konfiguracije 5.1. 
Zapravo, to je poput 5.1 surround sustava, ali uključuje dodatni zvučnik. Ovaj zvučnik pomaže u stvaranju potpunijeg i definitivno realističnijeg zvučnog iskustva.
Evo postavki:
- Sve je konfigurirano kao sustav 5.1
- Postoji dodatni zvučnik koji se obično postavlja na središnju stražnju stranu vašeg kućnog kina
Ideja konfiguracije 6.1 je da će dodati dodatnu dimenziju zvuka vašem kućnom kinu bez potrebe za postavljanjem potpunog 7.1 surround zvuka.
Ovo je sjajna ideja ako tražite taj dodatni učinak, ali imate mali budžet. You can add another rear speaker later on if needs be to complete the 7.1 setup below.
7.1 and 7.1.2 Surround Sound Systems
7.1 Surround Sound System
The 7.1 speaker configuration is the next step up from the 6.1 speaker system. This means that it includes all the components of a regular 5.1 channel speaker system but also includes two rear speakers, one more than the 6.1 system. 
These two rear speakers deliver surround sound which means that the two sides surround speakers won’t be responsible for both rear and surround sound unlike in 5.1 systems.
This gives an even more full, rounded sound experience to complete that surround sound cinematic effect. This makes it an eight-channel speaker system and is quite common.
7.1 Speaker System Setup
The 7.1 speaker system is similar to the 5.1 as mentioned before. In fact, the setup is the same except for the addition of two rear speakers. H
In general, the two additional rear speakers should ideally be placed at a 135 to a 150-degree angle from the center channel/TV. This ensures that you will achieve the best ad most optimal surround sound experience by amplifying background sounds. These are also satellite speakers. Remember, these are different from say bookshelf speakers (check out satellite vs bookshelf speakers).
You can get a better idea as to what this means by checking our our guide on surround vs surround back speakers.
7.1.2 Surround Sound System
Remember above we explained that the last number refers to the number of ‘height’ speakers?So what are height speakers?
Height speakers are additional surround sound speakers that are normally placed on the ceiling at the front of the home theater.These speakers add the dimension of height to the surround sound field to create a three-dimensional effect. So the 7.1.2 speaker system configuration is simply the 7.1 speaker system with 7 speakers and a subwoofer.The system includes the addition of two height speakers which are normally ceiling speakers or up-ward firing Dolby Atmos speakers. 
You will find this setup mostly for Dolby Atmos in-ceiling speakers. Dolby Atmos is a surround sound technology that adds the height dimensions to surround sound systems to create that 3D effect in the surround sound field. This type of configuration is for more high-end home theaters as it takes a bit more work and is certainly more expensive than the simpler configurations. However, it’s worth the money because all these speakers work together to provides a top-notch, realistic, and immersive home theater cinematic experience. 7.1.2 Surround Sound System Setup
Firstly, because this system normally includes ceiling speakers, you will find that it is most suited for basic ceilings made of drywall or plaster.
Additionally, the ceiling shouldn’t be higher than 14 feet but should be at least three feet directly above your left and right main front speaker and face the listener directly.
This surround sound configuration is becoming more popular in modern home theaters and does well to create a dome of sound that is like nothing else.
One important consideration however is to ensure that your system is Dolby Atmos compatible if you are using Dolby Atmo upward-firing speakers.
7.2 Surround Sound System
While 5.1 systems are the most popular today, 7.2 surround sound systems are becoming quite popular as well.
Today, many modern receivers support this surround sound layout. 7.2 surround sound systems are very similar to the 7.1 surround sound setup except that it has an additional subwoofer.
Why do you need two subwoofers?
Well, first of all, you don’t necessarily need two subwoofers. One is fine for most people. However, if you want stronger and more balanced bass, two subwoofers are a great choice.
It’s about creating a better overall bass experience really with excellent bass all around the room. As such, if you are a bass bum, a second subwoofer is a great choice for you.
7.2 Surround Sound System Setup
The 7.2 setup is similar to that of the 7.1 except that there is an additional subwoofer. There are many placement options for your subwoofers to get more bass. 
However, the most important consideration initially is that your receiver or amplifier needs to support two subwoofers to support the 7.2 configurations.
9.1 Surround Sound:The Cinematic Experience
Now for the hard-hitting, mega 9.1 home theater surround sound system. The 9.1 home theater surround system is a ten-channel surround sound system that includes nine speakers and a subwoofer.
Of course, these systems are quite expensive and are for very high-end home theater surround sound setup for the most discerning of audiophiles or those who crave a completely immersive surround sound experience.
This is why the 9.1 setup is not as common as the 5.1 or 7.1.2 home theater system.
The 9.1 surround system is really the same as the 7.1.2 configuration with the addition of two height speakers.
Remember, the height speakers are Dolby Atmos speakers that are used to add the dimension of height to the surround field to create a 3D surround sound effect.
9.1 Surround Sound System Setup
Setting up a 9.1 home theater system is not extremely complicated, however, each component should be positioned and chosen carefully considering the acoustics of the room and the specs of the audio components.
Failing to do so can cause any number of problems This is why setting up such a system requires a professional audio technician. For example, you will need a modern receiver that can handle the 9.1 configuration.
Keep in mind that similar to the 7.1 systems, so the ceiling shouldn’t be higher than 14 feet but should be at least three feet directly above your left and right main front speaker and face the listener directly.
9.1.2 Home Theater Surround System
The 9.1.2 surround sound home theater system is similar to the 9.1 system except that it has two front wide speakers, instead of the two front height speakers.
This is in addition to the two ceiling or upward-firing speakers.
If that is confusing, let’s explain further. In the 9.1.2 home theater system, you have a left and right front speaker, a center speaker, a subwoofer, a left and a right front wide speaker, a left and a right surround speaker, a left and a right rear speaker, and a left and a right ceiling speaker.
9.1.2 Surround Sound System Setup
The 9.1.2 configuration setup is to create a fully immersive, high-end dome sound experience. 
The left and right speakers provide an additional layer of sound to create that dome effect.
Here are the typical components:
| Item # | Description | Remarks |
| 2 | Center Speaker | 1 set |
| 3 | Left / Right Speaker | 1 for each side (L/R) |
| 4 | Left / Right Front Wide Speaker | 1 for each side (L/R) |
| 5 | Left / Right Surround Speaker | 1 for each side (L/R) |
| 6 | Left / Right Back Speaker | 1 for each side (L/R) |
| 7 | Left / Right Ceiling Speaker | 1 for each side (L/R) |
| 8 | Subwoofer | 1 set |
10.2 Home Theater Surround Sound System
The hard-hitting 10.2 home theater surround sound system is a full-blown, professional and advanced home theater system for high-end home theaters.
This one is for the most advanced home theater professionals who are seeking the highest fidelity in home theater setups.
The 10.2 configuration includes 14 discrete channels if the left and right point surround channels are included.
The 10.2 system was in fact built by the developers of THX, the high fidelity audio/visual reproduction standards for movie theaters.
This configuration includes seven front channels:left and right wide speakers, left and right height speakers, left and right front speakers, and a center front speaker.
There are three surround speakers, including one left, one back, and one right, and two subwoofers.
10.2 Surround Sound System Setup
The 10.2 system is of course not typical and so only a few, dedicated devices are currently sold to accommodate this configuration.
Here is the typical setup:
- Seven front channels: Left Wide, Left Height, Left, Center, Right, Right Height, Right Wide
- Three surround channels: Left Surround, Back Surround, Right Surround
- Two LFE channels: LFE Left and LFE Right
12.2 Home Theater Surround Sound System
The 12.2 home theater system is rather similar to the 10.2 setup except that the 12.2 augments the LS (left surround) and RS (right surround) channels by two-point surround channels.
This way, the overall sound can be better manipulated and controlled by the system because the mixer will be allowed to shift sounds in a distinct 360° circle around the movie watcher.
These additional speakers may be referred to as “point surround” or “diffuse surround” channels.
12.2 Surround Sound System Setup
These point surround speakers are normally placed at the same angles as the standard surround speakers at +/-120 degrees. As already mentioned, these speakers are made into diffuse radiators using dipole speakers.
Here is the setup with point surround channels:- Five front speakers: Left Wide, Left, Center, Right and Right Wide
- Five surround channels: Left Surround Diffuse, Left Surround Direct, Back Surround, Right Surround Diffuse and Right Surround Direct
- Two LFE channels: LFE Left, LFE Right (these are the subwoofers)
- Two Height channels: Left Height, Right Height
13.1 Home Theater Surround Sound and Beyond
The amazing 13.1 home theater surround sound system is one of the most complex home theater configurations out there.
As you might imagine, these setups are rather rare and you certainly won’t find them in a typical home theater system in a regular home. At this point, you are talking about high fidelity music rooms and theaters.
Higher Surround Sound Configurations
Dolby Digital Plus supports surround systems up to 13.1, and there are many other configurations for surround sound, like 12.2, 22.2, and more.
While these surround sound setups are fascinating and complex, they are a rare find in a typical home theater. However, they are fun to research and learn about, and there’s nothing wrong with dreaming of the possibilities!
Do You Need a Professional To Install Your Surround Sound System?
For simple setups such as the 3.1, 5.1 or even 7.2 home theater systems, you can surely go about that kind of setup yourself.
However, for the more complex configurations like the 9.1 or 10.2, you certainly need professional installers who have experience with things like overhead speakers and room acoustics.
Please be reminded that just purchasing a complex home theater surround system doesn’t mean or guarantee the best experience unless the room is set up professionally considering its own unique acoustics.
Consider Dolby Atmos
Many of these systems are Dolby Atmos compatible or based on the setup require Dolby Atmos speakers. If you want to create a cinematic experience, it’s not as good as RPX, but its the best you’ll get to in your house.
Dolby Atmos is a surround sound technology that creates a fuller cinematic experiencing which is high quality and highly realistic.
However, not all devices including receivers and amplifiers are compatible with Dolby Atmos. Before you go out and buy Dolby speakers, make sure your current devices are compatible. In addition, not all system,s support Dolby. For example, YouTube does not support Dolby audio. In fact, youtube does not support surround sound. For more information, read our article where we explore the question – does youtube support surround sound.
What Is The Best Number of Home Theater Channels
You may be surprised to learn that there is no magic number for how many speaker channels you should use. This is why we have so many different configurations.
The best options in terms of channels for you will depend solely on your room’s configurations including its size, shape, furniture, whether your home theater is soundproof or not, and many other considerations.
However, there are a number of rules of thumb to consider. For example, if your home theater is small, then you’ll want to go with a smaller number of speaker channels.
If you are having issues with your surround system where one or more speakers are not working, please check out our guide on how to make all speakers work on surround sound.
Surround Sound and Streaming Services
Today, many people get their content from streaming services like Netflix. While Netflix does support surround sound, not all content is compatible with surround sound.
For more information on how to determine if your Netflix title is compatible with surround sound and how to get Netflix to play through surround sound check out this guide.
What Does Each Channel In A Surround Sound System Do?
The audio signals connected to a surround sound system is divided through the different channels, which are then fed to the various speakers to be reproduced in specified frequencies such that the same sound is reproduced through the speakers in different ways.
Depending on the effect intended, emphasis on the sound quality will vary according to the channel it is fed into as dictated by the frequency settings on that speaker.
What Is The Difference Between 5.1 Channel And 2.1 Channel?
The bigger a soundbar is, the more channels it has. While a 2.1 channel soundbar has just two channels (one on either side) and a subwoofer, a 5.1 channel soundbar has two side speakers, a center channel and two extra speakers in the back which are either built-in or external.
What Is The Difference Between 3.1 Channel And 5.1 Channel?
Soundbars with 3.1 channel contain a channel more than the 2.1 soundbars, a center channel for better, clearer speech and background sound effects.
5.1 Soundbars come with an external subwoofer and five other channels –two side channels, one center, one surround left, and one surround right channels.
How Far Away Should Surround Speakers Be?
It is recommended that the front speakers be at least three feet away from the center speaker (which should be aligned with the TV) on either side, facing the audience. They should also be at least 6 feet back from the viewers.
Zaključak
Surround sound channels can seem rather confusing at first with all the numbers and strange terminology. However, once you know what you are really looking at, you will find that it is quite simple really.
