These typically give you '5. The '5' refers to the five main speakers: two positioned behind you to the right and left, and three front speakers, which go left, right and centre of the TV. The '1' indicates the number of subwoofers. Although 5. You can also buy surround sound systems with an amplifier unit or 'receiver' , though not a Blu-ray or DVD player, but it's the full package that is usually termed a 'home cinema system'.
If you already own a player, it's likely to be cheaper to just buy a surround sound system. Do carefully check what's included, though, as some manufacturers and retailers use the terms interchangeably.
Most Blu-ray films are recorded in a multi-channel audio format, such as Dolby Digital. Certain films and shows screened on TV are also recorded in surround sound. Many can be found on Sky's movie channels and other high-definition HD channels - to find them, look out for the Dolby Digital logo or 'DD' in the programme guide or in the corner of the screen.
If you don't want speaker cable snaking round your living room, you could opt for a system with wireless rear speakers. This system uses a radio transmitter so that the rear speakers can receive sound from the amplifier.
You'll still need to connect them to the mains for power, though. Test score. Want top-quality sound from your TV? HB Haddi Browne. TV sound systems compared We tested examples of each product against each other using our expert listening panel. A four or five-star sound bar will provide better sound than your TV's speakers — no great surprise there. Simply put, stereo systems include 2 speakers : a left and a right. This means that sound is only output in 2 channels which is basically industry talk for a speaker.
Stereo speakers can generally be connected to mixers that allow devices to vary left and right speaker output for some level of dynamic sound.
Surround sound, on the other hand, is a system with 3 or more speakers. A basic surround sound setup would be a center channel, and a left and right. That said, surround sound systems more commonly come in 5 and 7 channel setups.
Audio for a surround sound system has to be sent though a mixer so that it can create a sound field. This basically refers to the way the audio is output into the room, and creates a more immersive experience for the listener. Both stereo and surround sound systems can have a subwoofer included, although this is much more common with surround sound.
Stereo systems that have separate subwoofers will typically be PC speaker systems, meaning the speakers are usually smaller. A hi-fi system, however, will usually not have an external subwoofer.
When building a home theater setup, most people look for the best sound possible. However, not everyone agrees on which is the best sound system for a home theater. Although it might be obvious to you based on the major differences, but not everyone will benefit from surround sound in their home theater.
This might sound like a silly thing to say, but not all audio is treated the same by speaker systems. This is where the difference between surround sound and stereo comes into play. For example, stereo should be the only choice if your plan is to use your home theater for music. Whether this be listening to streamed music, vinyl, CDs, or mixing your own songs, stereo speakers will always win.
This is simply because music is pretty much always recorded in stereo. This is exactly the same with your headphones, regardless of whether they claim to have dynamic audio or not.
Music tracks are still output in stereo, but the mixer can modify the volume and output of each channel to make the sound more dynamic. On the other hand, surround sound is better for movies and games , but not necessarily for TV shows. Read my article on muffled surround sound. Surround sound will create a more dynamic sound experience within the space, which refers to the sound traveling at you from all directions.
This is the main reason people upgrade to surround sound , particularly if their home theater is for watching movies. However, if you plan on having a mixed media system, meaning a combination of music and visual media, then surround sound will still be the way forward.
Surround sound systems will come with a stereo setting, which only outputs through the 2 front channels. A final factor to consider when deciding which is better is the size of your home theater room.
A large room will definitely benefit more from surround sound than a small one. As mentioned above, speakers in home cinema systems have to meet different requirements depending on the frequency assigned to them. The allocation of the frequencies played back is controlled by the AV receiver via the crossover.
In a home cinema system, it is essential to match the amplifier settings to the characteristics of the speakers. This example illustrates the problem. A speaker manufacturer separates the frequency range of its satellite subwoofer system at Hz with an edge steepness of 18 dB.
Frequencies below Hz are therefore routed to the sub, and everything above — to the satellites. So far, so good. However, if this speaker set is connected to an amplifier, and the subwoofer output of which is designed for a crossover frequency of 90 Hz with an edge steepness of 24 dB, the connection values simply do not match.
Because there is no standardisation , manufacturers of AV receivers and speakers enjoy — to put it bluntly — a certain freedom to play around. While a deviation of the crossover frequency from 80 to 90 Hz may still be justifiable, the usual differences of to 80 Hz, for example, can cause drastic errors in bass reproduction.
There are other important differences between Hi-Fi systems and home cinema systems.
