1. Tips for room size Audio and electro-acoustic conversion tools will eventually become sound echoing in your living room. The sound is sensitive to space. Although it is difficult to make it clear, the larger the room, the greater the demand for sound energy. Therefore, please carefully consider your requirements for sound, if it is only used as background music, it is easier to handle. If you want to fully appreciate the charm of audio, you must consider the appropriate sound pressure, especially the size of the space has a huge impact on low frequencies. (Tips: Bookshelf speakers can be considered below 20 square meters, floor-standing speakers should be considered above 20 square meters!) 2. Market research Run a few more stores to do audition comparisons, and try to choose merchants with good reputation and mature service! Although there is no business and no rape, but there is also a way to steal, not all JS is ignorant of money. Good technology and services are visible, but it requires a certain amount of judgment. The kind of statement that uses optical fiber to conduct signals is the most advanced audio technology in the world. Obviously nonsense, he regarded you as a countryman of the last century Too. For more knowledge, please dive in our forum! 3. Environmental considerations Note that the related lines must be pre-buried in the decoration, such as surround speaker cable, projection video cable, etc. Try not to put the speaker on the table, that is to say, your TV cabinet should not be designed to be long and bulky! Super long? 3 meters? Halo, hurry to give away ... Also, do n’t take the sound cabinet space for granted It is only 15 cm in height, actually more than 20 cm is more representative! Of course, it is best to do it according to the real thing, so as not to get the head to find that you ca n’t put down the equipment! My suggestion is to buy a dedicated audio TV cabinet! By the way, Do n’t be a drawer, it ’s really stupid, at most there is a glass door, but it is best to omit it. When the sound causes resonance, you will find that the glass door may be redundant! 4. Service In any case, merchants should provide on-site installation and commissioning services! Relevant accessories must be complete! For example, signal cables, speaker cables, and mounting brackets for surround speakers. Even if the product itself is not provided, the merchant is also obliged to remind you to buy or attach! Some merchants have installed the equipment and left after making the sound. It ’s wrong, he should tell you the brief operation essentials, and tell you the possible situations and coping methods. In case you ca n’t solve it, there should be at least 2 to 3 on-site after-sales services. 5. About AV surround speakers In fact, the standard AV multi-channel audio and video system requires that the speaker specifications of each channel are the same, which means that each channel requires the same box, but in fact this will cause a substantial increase in cost, and there are compromises in reality. Yes, that is, the surround and center speakers are actually reduced models, but please try to use the same series of products of the same brand, so that it is more stable, otherwise the various parameters cannot be kept close, and the sound will not be coherent! 6. Source Carrier Any AV system needs software support, that is to say, if you want Dolby AC-3 sound, then in addition to configuring hardware that meets AV-3 requirements, there must be a carrier with AV-3 sound (DVD) software! Also, even if the sound effect of AC-3 is marked on the software, the 5.1 (or N.1) channel must be marked before it is finished, because AC-3 also includes 2 channels, that is to say , AC-3 does not mean that it must have 5.1 channels! Is there such a case for DTS? I have not studied it, it is estimated that it is almost the same, but the birth of DTS is for multi-channel, rarely seen only 2 channel effect DTS disc. In addition, in terms of data volume, DTS is much higher than AC-3. Therefore, in theory, the sound effect of DTS is better than AC-3. For various sound effect formats, please refer to our forum for more information, because it is organized from the Internet, I am sorry to take it out 7. How many theater systems should I build? There are various multi-channel systems such as 5.1, 6.1, 7.1, 8.1, and 9.1. How do I choose? We know that the most popular ones are AC-3 and DTS multi-channel AV systems. With the support of film companies, if their DVD discs only have the 5.1 mark on them, what do we buy more speakers for? Of course, the hardware can also simulate a variety of multi-channel effects, but it is only a simulation, a lively effect, there is no essential improvement, as mentioned before, without the support of software vendors, no more channels are wasted! So what kind of system should I buy, look at the label on the back of the genuine DVD on hand or on the market to understand what to do!
