[Home Theater Network HDAV.com.cn] Home theater is a system, not only related to equipment, but also has certain requirements for space. The function of this article is to tell you a thought process that is convenient for planning your home theater based on your actual situation.
The first step: determine the budget
Although home theater is used to meet the spiritual and cultural needs, it is essentially a consumption, or you have to pay in RMB. Since it is consumption, it is necessary to plan the budget.
How much does the home theater cost? In fact, just like the decoration, this answer is really different for everyone. Therefore, we can only say a rough range. Here, we don't talk about thousands of dollars in home cinema, only professional home theater, professional home theater refers to the use of 1080P resolution home projector, with amplifier, passive home theater dedicated speakers, plus high-definition playback These devices, in terms of current market prices, generally start at around RMB 20,000, and go up to 50,000, 100,000, 150,000, and 200,000.
Don't look down on the 20,000 entry-level home theater. In the past two years, the performance of various entry-level equipment has been upgraded a lot, but the price has not increased much. Using a car to make an analogy, an entry-level professional home theater of about 20,000 yuan is equivalent to a class A car like Fox, Sagitar, and Corolla. Although it is insufficient, it is enough for ordinary families. Of course, if you have ample budget, there will be better performance equipment waiting for you. After all, Passat and Mondeo are still superior to Sagitar and Fox.
Step 2: Choose a room
With the renminbi, you still have to have a room. In most cases, most home theaters will choose to be built in the living room, because after all, the function of the living room is similar to that of the home theater, and the superimposed assembly will not be particularly awkward. Of course, if there are more rooms, you can also choose a separate room for your home theater. Although it seems very good to lie down and watch a movie, there are not many people who choose to do a home theater in the bedroom. If you have to do this, of course, no one will stop you.
The third step: determine the number of channels and embedding
The most important part of the home theater is the speaker. The surround effect brought by multi-channel is also the main charm of professional home theater. The clear dialogue, the bullets that are shuttled around, the fighters roaring overhead, these sound effects can be professional Feel in the home theater.
Since it is multi-channel surround, there is a problem, in the end is a few channels! At present, 5.1 channel is the most basic configuration of the home theater, here to explain the meaning of 5.1, 5 means that there are 5 channels, " .1" is the number of subwoofers. 7.1 is based on the addition of the surround sound of the two channels behind the 5.1, so that the sound is surrounded more complete.
Dolby's current DOLBY ATMOS immersive sound technology is gradually entering the family. The Dolby panoramic sound is not explained in detail here. Simply mention the essence of this technology, that is, you will be surrounded by more speakers. Let the sound transition more natural. For example, in the 5.1 system, the plane flies from the left to the right in the picture, you hear the roar of the engine from the left speaker to the right, but the transition is directly past, that is, directly from the left On the right side, there is no connection in the middle, but in the panoramic sound system, you can feel that the sound is from the left through the sky and then to the right, the sound is more vivid and natural.
At present, the panoramic sounds that can be realized in the family are mainly 5.1.2 and 5.1.4, 7.1.2 and 7.1.4. How to understand this number? The first two figures have been explained above, and the last figure refers to the ceiling. The channel. For example, in 7.1.4, there are 7 channels on the ground, divided into the first three, the middle two, and the back two. ".1" means there is a subwoofer channel, and ".4" means the ceiling has 4 Channels.
In effect, of course, the more the number of channels, the better, but the price will naturally increase. After choosing the channel, you need to buy the speaker cable and HDMI cable and then bury it in the wall during the decoration, so the map is cheap to buy the poor quality line, the future is to find trouble for yourself. There is a special article on how to embed the line. I won’t say much here.
Part 4: Determining the projection distance and screen size
After talking about the sound, let's take a look at the big picture. Because of the working principle of the projector, there needs to be a distance between the lens and the screen. This distance is called the pitch. Each projector has a different pitch because of different lens parameters. For example, the same is 3 meters, some machines can cast 100 inches, and some may not be able to vote.
Determining the pitch is important, and it also determines where your projector is installed (usually hoisted on the ceiling) and how long the HDMI cable needs to be buried beforehand. Each projector's parameter table will have a projection distance and the corresponding screen size. If you need a 120-inch screen, you need to select a projection that can achieve a 120-inch screen within the range of the pitch you can choose. machine.
In another case, your room is particularly narrow, or the installation conditions are limited, or the apartment type is different. There is not enough distance to place the projector, but you want to enjoy the big picture. In this case, it is necessary to purchase a short-throw projector, which has a short pitch and can be placed on a TV cabinet. However, the edge distortion of the short focus screen will increase, and the machine selection surface will be less than the conventional model. At present, there are some products called laser TVs, which are essentially ultra-short-throw projectors using laser light sources. This model is also a good choice if space or installation conditions are limited and can afford higher costs.
Step 5: Purchase equipment
After the basic work above is fully prepared, you can purchase speakers, amplifiers, players, projectors, cables, curtains and other equipment to install. What needs to be explained here is that the budget for purchasing equipment is only a reference. Many users often choose to modify the budget when determining the plan. If the consumption power can be guaranteed, some people will raise the budget appropriately to get better use. Feel.
