Eight essential elements for home theater formation
So, what other aspects should be paid attention to when setting up a home theater? Here are some of the basic elements and key points of the cinema selection with our practical experience.
First: use occasions
Home theater is the cinema system used in the home, so it must have a place to be placed, living room, bedroom, study, or a special audition room. Different environments have different requirements for equipment, open and closed spaces. The audio and video effects are completely different. This is the first thing we have to consider. If the family's public activity area is a stylish and simple system, the independent space can be fully played, and the combination of the enthusiast level is better. For good shading, you can consider large-screen projection. It is best not to use professional or business machines with a screen ratio of 4:3. Instead, you should use a 16:9 home projector. In bright environments, only large-size TVs are available. 9 of the 32-inch screen is the most basic requirement, if the environment allows, of course, the bigger the better.
Second: area size
The size of the audiovisual area is closely related to how the equipment is selected and matched. Small rooms are best not to use large speakers, big rooms do not use small LCD TVs, this is the basic common sense of optional equipment. Generally speaking, the enclosed space of more than 18 square meters can be projected, and the audio-visual room of more than 50 square meters will let you take out a large amount of equipment to purchase funds, but also have good acoustic treatment, of course, the effect is small. The room is hard to reach. However, there is no absolute matter. If the equipment is carefully selected and the room characteristics are adjusted, even if it is only 10 square meters, it can also play a good effect.
Third: the proportion of the room
Do not use the room where the room length, width and height are integer multiples. Otherwise, the strong standing wave will let you do everything. The best equipment will not have a good sound in such an environment. If you have no choice, you must use the bookshelves, wardrobes and other indoor items to break it up. If conditions permit, the proportion of the room can also be changed by means of ceiling, partition or floor treatment during renovation.
Fourth: Space, Acoustic Processing If sufficient funds are available, professional acoustic processing will make you more effective, and audio and video consultants can help, but there are not many high-level companies. If you don't have enough investment, you can't just be accompanied by bad voices. As long as you use your heart, you can get good results. But some basic acoustic rules we must follow, such as not having too many, too large glass windows, cabinets, not too thin bookcases, etc., they are all sound killers, especially for low frequencies, such a complete environment It is a disaster, and it is not reasonable. Carpets, sofas, coffee tables, hanging pictures, curtains, etc. are all good props for tuning. The environment of spreading, absorbing and other treatments is definitely much better than the four walls. At this time, you may wish to come up with some wisdom and artistic temperament to beautify your home. In addition, if the upper screen projection, in addition to strict shading treatment, the room color should not be too bright, too much reflective.
Fifth: The amount and proportion of investment is the investment in Article 5, because the environment is the most important. If the environment is not good and it is not processed, no amount of investment is useless. Money is not a panacea. If the adjustment is square, the equipment of the price will have a good effect. As for investment, entry-level video equipment, including 20,000 yuan together, can basically meet the standard, and high-end spending of 1 million. If you don't carefully adjust, the effect may be very unusual. We have seen too much in this situation. The key is whether you care.
As for the proportion of investment, about 5-10 million yuan, the source of the signal: video: audio: accessories (wire, rack, etc.) ratio of 1:3:4:1 should be generally more appropriate. But this is not absolute. Sometimes the characteristics of equipment, cost-effectiveness and other factors will also affect the distribution of investment proportions. It is necessary to be flexible in terms of local conditions. The important thing is that the proportion of investment should not be too unbalanced to form a bucket effect.
Sixth: Before pre-embedding and connecting the wire, it is best to plan the wire, including the power cable, the speaker cable, and the signal cable. The lighting, control, etc. are all considered. It is best to do the acoustic processing together. Or, hanging the line everywhere can make you upset. Remember to use high-quality wire, don't forget to add the root HDMI cable, now the audio and video are best to use digital transmission, you have to remember. Wire connection also has a lot of skills, but some basic principles also need to be observed, such as signal lines should not be close to the power line, speaker line; digital transmission should be clearly separated from analog transmission; wire should not be bent at an angle less than 90 degrees Wait.
Seventh: Matching skills High-brightness projectors with low-gain screens, low-sensitivity speakers with high-power amplifiers, these are the basic matching rules. Each piece of equipment has its own style and personality. To integrate it as a whole, you have to go to the audio city and the store several times to get more information. With the length of the match, you can only take it with you first. Please take a look at Home Theater Technology, which will teach you a lot of skills.
Eighth: equipment debugging and system adjustment When the equipment is in place, after the installation is completed, the commissioning work begins. There is no sound, no picture, you need to know the function of each piece of equipment. TVs and projectors must be borrowed from software to test and adjust. For example, "HIVI CAST" is an easy-to-use debugging software. The sound is more complicated. In addition to the correct installation according to the cinema standard, the position and angle of the center and the surround should be adjusted repeatedly, and the subwoofer needs a little bit of movement. A little bit of trial, as well as sound absorption and diffusion processing. There are skills everywhere. Play slowly! Interesting in it. You know, if the plane doesn't go into the sky, the earthquake is not necessarily a problem with the equipment.
Although the above is just some experience, basic common sense may be missed. However, it can be believed that after careful matching and adjustment, not only the audio-visual effect is better, but the theater feels even better. You have become an audio-visual expert for a long time. And the endless audio and video fun began.
