16 Feb 10 Surround Sound Format Basics For Home Theater Systems – Dolby Labs Vs Digital Theater
Sound systems are a very important part of any home theater – but they are a piece that is often overlooked. Great sound makes the difference when you try to achieve the complete cinema experience at home.
Great sound for TV and DVD Simple increases the opportunity, but with Rotten Sound – you do not get the feeling that you would as if you are in the cinema itself, you know, almost hypnotic experiencethe fun and thrills, as you could in the cinema.
Whether you or buying your home cinema aim to upgrade to the best speakers you can afford and not only will you be rewarded with sound quality to buy, you do not need to replace in coming years.
Surround sound sources
But if you want great sound then consider the format that should have your home theater. Are Home Theater surround sound andThere are two major companies to choose from: Dolby Labs. and Digital Theater Systems (DTS).
Dolby Labs is the creator of Dolby Digital and Dolby Pro Logic, DTS, while the provider of the configuration are known as Digital Theater sound format.
The range of options provided by both companies enormously, and try and can choose from two giddy best.
DTS provides a sound clearer and sharper, because they are using an encoding technologymore uses compression used as the Dolby encoding.
But the market moves Dolby and is therefore often available on DVD and television.
Surround Sound Formats
Surround sound exactly does is mimic surround sound in an attempt to suicide.
And there are differences of which to choose.
5.1, indicating a system with five speakers and 1 subwoofer to deliver sound, which also referred to as DolbyDigital.
6.1 (THX), the center speaker is in the center is located behind the listener to yet another layer of sound.
7.1 Surround is the latest version and still further includes a speaker to create an authentic sound.
The right of the extra speakers in the surround-sound system should provide a more realistic sound and you should find yourself in the middle of the movie action. – As if you reallythe film itself!
What format do you do an A / V receiver is required for you
As the central source of power of the home entertainment system, which is responsible for controlling, surround-sound decoding, signal processing tuner, amplifier and as an AM / FM radio. Fits most A / V receiver supports Dolby and DTS.
As always, the choice of the A / V receiver over whelming, as the variety is huge, and would try to go for the very simple toOption to purchase the cheapest available.
Acquisition of a receiver, which costs less than $ 400, will be of poor quality, while a safe choice for excellent quality receiver that will not break the bank.
Abstract
Surround Sound expands the conversation, you want to invest a home theater or are thinking about expansion and you want a great home theater experience you have to have great sound.
Do your homework onSystems are available and remember good quality speakers are important for the implementation of sound, then schedule a significant effort to make.
Decide what you will support the desired format to the recipient, and how many speakers should be set up.
03 Feb 10 Surround Sound for Your Home Theater System
If you think you can take the old stereo speakers and hook them up to your TV to surround sound for your home theater system, you are cheating yourself out of an acoustic delight. While you were the audio sounds from the program that you saw to hear, but surround sound is slightly different. With a properly adjusted set of speakers, the sound quality is optimized so that you feel as if that is what is happening on the TV screen properly found in the room where you sit – especially when you close your eyes!
A good number of speakers also includes the so-called digital media port in which you allow to extend the benefits of your home theater system yet. Use this option to purchase the music from your computer hard drive to play an iPod or a Bluetooth device, and enjoy the incredible range and tone to deliver the speakers.
A basic set of surround sound speakers for your> Home-theater system is mounted three to five speakers on the wall include a broad range and clear sound, along with a subwoofer will ensure further improvement of the entire sound spectrum. In general, you get two front speakers, two rear speakers, a center speaker and a subwoofer is needed for best sound. If you get everything set up, prepare to be amazed. You will be able to really feel "the sound as it echoes! It would be best to find a lot that has a magnetically shielded CenterSpeakers so that they can has been placed near your TV without any distortion of the image. Your subwoofer should include a power supply of its own for best results.
A good receiver is a large part of the surround-sound package for your home entertainment system. The receiver for your speakers should be as high as possible, the best performance for the sound, and should be at least a 4-channel Dolby Pro Logic decoder equipped. Search for the reception of digitalCinema Sound technology and auto-calibration for clear, crisp, realistic sound quality. The best receivers are filed separately and have different sound controls for music and movies, and easy to reach, connections for headphones, optional antennas, and of course speakers. Most include a microphone that the speakers for the balance, with the best audio with very little effort on your part.
07 Dec 09 Surround Sound Systems – How to Hook Up Surround Sound For Your Home Theater System
If you really want to get the excitement of a movie you feel at home, then you need to get a surround sound system.
You may already have the big screen in the room, but if you are not able to listen to the soundtrack at its best, then you miss half the fun!
However, many people feel that the installation of a surround sound system is too difficult – and that's too complicated for them to connect.
Well, it's not so difficult – the following pointsunderstand what you need to get your own surround sound set up.
1. Decide on the surround sound configuration you want.
Most modern DVDs come with a 5.1 surround soundtrack – so a 5.1 speaker setup is the most common speaker system that people have. This system has six speakers – a center speaker, front left and right, surround left and right and a subwoofer (for the bass). However, other common configrations are 7.1 and 7.2 surround sound speaker systems.
2. Buy an AV receiver / amplifier and speaker package – or a home theater-in-a-box system.
The AV receiver is the amplifier for the speakers – and the processor for 5.1 surround soundtrack. You must buy a separate 5.1 speaker package to connect to the surround sound receiver – and probably the speaker cables. The main advantage of an AV receiver is that you can connect a variety of external devices – such as DVD players, Blu-ray player, cable TVBoxes, DVD recorders, etc.
A home-theater-in-a-box system (HTiB) will come with the amplifier, speakers and all the cabling in one package – and often have a built-in DVD / Blu-ray player. However, there is often little room for connecting other devices of this type of system.
3. Connect the system together.
Connect the speakers to the speaker output on the AV receiver to the speaker cables. Place the center speaker to theCenter speaker output, leaving the front speakers on the front left speaker output, etc.
Connect the HDMI output of the DVD player to the first HDMI input on your receiver. This will send the DVD picture and sound to the receiver.
Connect the HDMI output on the AV receiver to the first (perhaps only), HDMI port on the TV. The AV receiver will use this to send the image on the TV screen.
Do the automatic speaker setup for the AV receiver (most have this). This sends a testsignal around your speakers and set a good balance.4. Play the movie!
5. How it all works
When you press play on the DVD player, the video and audio signals are sent to the AV receiver down the HDMI cable – make sure you select the correct input on the AV receiver and it will receive the signal.
The AV receiver then sends the picture to the TV – make sure you select the correct input on the TV (the TV may switch to the correct input when it gets the signal).
The AV Receiver sends the audio to the speakers. It should automatically the 5.1 mix on the DVD and send it out of the speaker system with surround sound. Summary
So we have it, a short checklist of what you need to buy to get a surround sound system in your home – and how you connect everything together. For more information about this process, then follow the links below.
Enjoy!
03 Dec 09 Home Theater Setup (Surround Sound Speaker Setup)
I will make the assumption that you have a surround sound or home theater receiver and start from there. There are 3 main home theater speaker setups which you will see termed 5.1, 6.1, and 7.1 channel surround. You will also see mentioned the terms Dolby Digital, DTS, and Dolby Pro Logic. Let’s dispense with the latter first: if your receiver is only Pro Logic (only older receivers at this point) you do not need to worry about 6.1 or 7.1 surround. There are some other formats such as Dolby Digital EX, Dolby Pro Logic IIx, Dolby TrueHD, DTS Neo: 6.1, DTS-ES, True Surround XT, and undoubtedly more.
The two factors are taken into account:
1. how many channels are required to enable your system, and
2. You want to buy that many speakers?
All recipients, more than 5.1-channel will also work well, with a 5.1-channel setup. Of course, 7.1 better than 5.1 surround sound, but at the cost of two additional speakers. IfYou have a limited budget you must decide whether they buy 5.1 higher quality speakers, or go for cheaper speakers to provide 7.1-channels. By the way, the .1 channel is the home theater subwoofer. The subwoofer is really needed in my opinion, for home theater. It will operate a system without, but I do not recommend this to go without for the home theater. The center channel is also very important for a home theater and serves toAnchor the sound of the screen. If you are on our side through the link at the end of this article, you can see pictures of the following descriptions. These are the recommended placements according to Dolby Labs.
5.1-channel surround system:
A). Center speaker centered on video source
B). Sub-woofer (s) in the arc with the main L & R speakers between speakers and video source
C). L & R front on a 22-30 degree angle from the meeting on an equidistant arc connecting theCenter channel and subs —
D). L & R surround equidistant and on 90-110 degree angle from the upright
6.1 surround system:
A). Center speaker centered on video source
B). Sub-woofer (s) in the arc with the main L & R speakers between speakers and video source
C). L & R front on a 22-30 degree angle from the meeting on an equidistant arc connecting the center channel and subs —
D). L & R surround equidistant and on 90-110 degree angle from theSitting position
E). Rear center 180 degrees (directly behind) the sitting position
7.1-channel surround system:
A). Center speaker centered on video source
B). Sub-woofer (s) in the arc with the main L & R speakers between speakers and video source
C). L & R front on a 22-30 degree angle from the meeting on an equidistant arc connecting the center channel and subs —
D). L & R surround equidistant and on 90-110 degree angle from the upright
E). L& R rear equidistant and located on a 135-150 degree angle from the listening position.
Sub-woofer Setup
Your subwoofer can have a switch for Dolby Digital / Pro-Logic. If you have a Dolby Digital-capable receiver, you put on it that even if you are using Logic Pro. The same applies if you have multiple inputs on your sub. If your input is labeled LFE it is the equivalent of a Dolby Digital input. They want the input to the RCA-style plug (or plugs) if you are using sub-woofer usingin a surround system.
If your speaker level binding post inputs have, they are almost always for using the subwoofer in a non surround sound speaker setup. Save the subwoofer level control to about halfway before the white noise test tone to calibrate your receiver speaker output level. Be sure the test run, and balance your speaker levels to have running right surround system.
Do not worry about the crossover frequency control of the Sub connector for Dolby Digital orbetter systems. For Pro Logic set it to the place where drops in your main bass speakers that look at the documentation needed for your speakers.
If you use your sub in a surround system, you can use the advantage of using the speaker level inputs on the back of the sub. The advantage is if you have small speakers. The recipient left and right channels are connected directly to the subwoofer, and the left and right speakers to the speaker outputConnectors on the sub-woofer. What this does, it is the sub to the bass that the main speakers do not do the course, the other types of connections would be to produce. The advantage here is the fact that the sub-woofer connected in this way, it filters the bass from the signal, so that your main speakers never attempt to the bass that it can process to produce. This results in clearer, cleaner sound and more volume capability from your main speakers.
Sub-woofer placementgenerally as follows for other speakers. It is true that bass is omnidirectional, and so you should be able to a sub-woofer available everywhere, but as usual, depends on your situation. I play music loud, and can tell where the subwoofer is by feeling the vibrations. I find it very annoying to have the bass appear to come from the front of the room, but the vibrations of the bass coming from a different direction. That's why I always prefer a subwoofer speaker on the front ofRoom.
How do you make the most out of your speakers (Like your sound quality for no additional funds will improve)
The first consideration with a new speaker system is the placement and wiring of the second one, both of which deserve consideration. We cover wiring first with some generalities that apply to all types of speakers. The placement is in part to limit speakers to stay.
Wiring speakers
First and foremost wire can pick very important. IfYour speakers are designed for installation on the wall, you will need speaker cable rated cl3 or equivalent. If outdoor speakers, you should first try to the so-called direct burial cable or equivalent. Next, if you have the sound quality at all care that is 22 gauge cable is not recommended. It can be used in very small editions, and has little to hide, but because of the resistance can be found to sacrifice some sound quality. I would recommend 16 gauge wire for most runs in, unless you really get the most out of want yourSpeaker, in this case, use 12 gauge or larger. For a long term, I would recommend greater than 16 gauge. (We have a cable items and distance chart on our website at the link below.) I personally use a good audio quality 12 gauge cable itself, but you will pay more for cable just as large. The advantages are better dynamic response of the amplifier and your speakers may be better because of the low resistance wire system. As always, you can find the price point of the speakers on the cable. Insert not expensiveCables on cheap speakers, and vice versa. BTW, do not try to romex (house wiring) use in place of decent quality audio cable. Truly say, not only. For so many reasons.
A frequent question is whether imagination is a cable no difference. I must say here that many people who consider much under so much snake-oil. Personally, I think I can hear some differences, depending on the quality of the related system. In other words, any audible differences in the cables are more noticeablein a system with greater resolution. Also consider that many listeners not selling cable claim to hear a difference. Consider a double-blind tests carefully. I can usually select holes in the logic behind most of these tests, and point out factors not considered. A prime example was an amplification test (by a major audio magazine) that are facing the amplifier level, has a double blind test, and claimed that the amps sounded identical, so they recommend that everyone buy the cheaper amp.
Here is theRUB: In their exact conditions that are not normal listening conditions, the amplifiers sounded the same. Consider these remain unmentioned idea: The cheaper amp had less power than the others listen, and under normal conditions, say with loud rock music and inefficient or difficult to drive speakers would have pooped levels before they meet to hear, let alone by clipping and falsification of over-driving of the amplifier. One problem with the double-blind tests toexactly, they have to each factor in the universe, which could affect the results of control and unknown factors. The other is to compare it all at once a playing field, remove or reduce it on purpose, the differences, then triumphantly proclaim that they are all equal. The perfect example from above is level matching at a volume not to emphasize, the easier said amp.
Polarity or phasing out of the speakers is very important. This means you will find the Wire with a stripe or writing on one side and a connection to either the wire + (red) or – (black) on the amplifier and speakers. It does not matter whether the strips connecting the wire to plus or minus, as long as it is the same at both ends, and all speakers. I always get in touch with the Plus to the strip, only to be consistent. If you do this wrong you lose almost all your bass playing, and voices will float centered instead of when they should be.
> Home Speaker Placement
Ideal location for the best sound is with the type of speakers you have to vary, but we can supply some good generalities. Of course, for a surround system, you have some limitations built. The center channel needs to go up or (in the middle of your TV, or perhaps centered behind a screen) and the front left and right have to go to the left and right front. So for the rest of the speakers. It should be added at this pointSurround Sound for the placement is the ideal all 3 front speakers at an equal distance from the listener. This actually makes the front speakers on an arc. It is surrounded by generally well placed to the rear a little higher than ear level, so that all listeners get a better chance to hear all the speakers. Apart from the obvious detail of surround sound, here is how the sound of your system to improve free.
First, nothing will introduce the speakers, and if they get into a situationWardrobe make sure that the front is the speaker even with the front of the housing. So, remember that some speakers as the rear ported diversity lead very bad in the cupboards. Make sure speaker ports, which are not blocked in front, can be rear, side or elsewhere. This applies to both subwoofer too. Stability is also important that the speaker must remain stable at high volume levels. If they move with loud drum beats, your system will be deprived of punch and impact. If youSpeaker stands ensure that they are stable enough for the size of the speakers you have. A quick tip is to mortite some Blu-Tack or putty between the speaker and to use passive, to improve the tying and add stability. Spikes on the ground which is good for rooms with carpet.
Next click on the sound of the speakers. Many speakers sound better when aimed directly at the receiver and situated on the ears. This is not always the case. If the treble or voices sound a little toosharply, then maybe the speaker will sound better place directly from the target to the listener. Listen to the bass. Is it boom, or is missing? If your speakers a bit of rumbling noise, as they are in one tonne of that can probably bass reproduction by the speaker to be further improved by a wall or corner. If your speakers are too weak in the bass, so they can sound better, closer to a wall. Remember, do not block any bass ports. If the speaker is rear ported, it needs a little space from the wall andClearance will be on the pages of the speaker to be. A little tweak you might try some speakers sound better with the speaker grills. Remove them and see if they sound better. In many cases, there is no significant difference, but it costs nothing to try it.
Other problems: If your speakers correctly, as described above voices are not sharply locked in place, you can leak through your speakers too far apart. This generally applies to stereo, notSurround sound. If it is not used on a surround system, the subwoofer crossover point should be adjusted to the drop-off collapse in the bass from your main speakers. You can use these listed in your documentation, usually on the order of the-3db point. If after all your speakers do not seem to perform as they should, you should consider whether the amplifier is connected with them until the task to drive. There are more questions here than power, especially impedance. An amplifier,has a high performance 8th May ohm speaker drive well and do very poorly on 4 ohm speakers if the amplifier is not designed for "high current" or rated power into 4 ohm speakers. In addition, many are amplifier (or receiver, home theater amplifier, etc) manufacturers use various methods to exaggerate the wattage of the amplifier. The real evaluation is sought as the RMS rating, and should be submitted (4 ohms in a specific resistance, 8 ohms), etc., to a certain distortionAssessment.

As the name says, a surround sound system literally surrounds the listener with sound, while there have been significant advances in this technology recently, there was a huge gap in time between the introduction of this technology and the significant improvements that we in the last years has seen. The world of video has changed in the last three decades has sound technology only recently begun to be pulled level.
The surge of technological advances in this mediumin many different systems on the market today showed. Many consumers find it confusing, but the good news is that most devices to decode these formats to do so routinely. In other words, you need a PhD in terminology in order to enjoy movies or music with surround sound system. What will be required, but if you get the maximum enjoyment of your home theater and surround sound system are of good quality speakers and a first-class AVRecipients.
The following comments may help to dispel some of the puzzles of common surround sound formats.
Most DVDs and some programs that are on digital cable or satellite channels in the Dolby Digital AC-3 will be found that by far the most frequently seen surround-sound system. It is a 5.1-channel format. In all formats, the first number indicates the number of speakers and the second is the subwoofer. However, surround sound is not required to use this system as youDolby Digital for older technology can not be used include surround sound in their format.
To interpret or decode the signals from other media such as cassettes old videotapes or television programs you use a Dolby Pro Logic system mentioned. This is understandable given the generally known for his ability to take two speaker sounds, and they left in the superbly realistic surround replication.
The leading contender for Dolby, to see if they sound DTS and DTS-ES, usually onlyon DVDs, the company response to 6.1 Dolby surround system. As a rival to Dolby's Pro Logic DTS Neo: 6 is to produce excellent imitations of surround sound from existing 2-channel Pro Logic Media is very similar.
The main motive for providing this information, and is, so you know that there is a difference and that the purchase of equipment and DVDs that are synchronized with each other. Supports most home theater systems are both Dolby Digital andDTS, you should make sure however that you format your system requires from the outset to make the proper assessment to be aware when purchasing. The alternative would, in a tone that is less than desirable.
The more speakers you have a great quality of sound than less, but poor quality speakers totally ruining the beauty of the sound of your home theater system is available. Your speakers should be your biggest consideration init comes to building your perfect system. Like anything in life, the appropriate formats to come to a matter of choice.
