How to build a home theater with a projector [Detailed explanation]

How to build a home theater with a projector

Because projectors are not very popular at present, many functions of projectors have not been tapped by users, not to mention replacing large-screen color TVs with projectors to achieve the effect of home theater. The introduction of home projector shows that the function of the projector has begun to approach the home. Now, home projector can be used with various video input devices, and the video images can be enlarged to the degree close to the real thing. Below, the author will talk with you about how to build a unique home theater with home projector.

First, the purpose of setting up a cinema

With the continuous improvement of living conditions, consumption level and enjoyment ability, people have begun to be dissatisfied with the traditional home theater effect combined with TV. These AV fans always want to be unique and create a brand-new home theater effect with projectors. They hope that their personal cinemas will improve qualitatively in video and surround sound. This new cinema effect built by projector will realize the perfect combination of technology, art, entertainment and rich imagination. In this personalized space, users will truly feel the auditory and visual shock brought by the most cutting-edge scientific and technological innovation.

Second, the feasibility of the scheme

Many people say that the effect of traditional home theater is very different from that of theater or cinema. In fact, the difference in effect is determined by many factors, the most important of which is hardware. For example, in terms of vision, the visual effect that ordinary TV sets can bring is very limited, while the audio-visual facilities in cinemas are much stronger than TV sets. For example, its sound system is more flexible. Of course, if you build a home theater with a projector, its advantages may even surpass the theater. For example, the projector can get rid of the defects of traditional TV sets and bring us the enjoyment of high-definition big screen; Moreover, due to the restriction of objective factors such as large audience and large space, it is difficult for the theater to achieve realistic auditory effects. It is precisely because of these defects that the new home theater will continue to be favored by people.

Third, the implementation plan

If you want to set up your own home theater with a projector, you can connect the projector in the following way first. First of all, you should realize the visual effect of home theater. You can connect the projector to the TV first. Due to the different models of TV and projector, the specific connection method will be slightly different. You can refer to the specific instructions of the projector. After connecting the TV with the projector correctly, we can make the TV realize the projection function; Of course, if you don't have a TV in your hand for the time being, you can directly use the all-channel high-frequency video switch. With it, we can also accept all TV programs. Next, we should set up a sound effect system. Just connect the projector with VCD, audio, power amplifier or other multimedia audio-visual equipment correctly. Maybe you will say, is it that simple to set up a home theater? Of course not. This is just the most basic physical connection. With these simple physical connections, of course, we can't expect any powerful effect. In addition to the correct connection is necessary, to achieve a good audio-visual home theater, we must also pay attention to the following details: 1, and choose a good theater space.

The size of the space directly affects the auditory effect of the theater. It is also necessary to choose a good theater space to make the auditory effect realistic. Generally speaking, it is best to choose a rectangular room as a home theater, because a rectangular room can play a unique role in the harmony of modulation sound effects.

2. Choose a good projection screen

As a part of home theater, the importance of projection screen can not be ignored. The projector itself is often regarded as the key point that affects the picture quality, but the ultimate goal of setting up a projection projector is to reproduce the image on the screen, so the projection screen is also an important factor that ultimately determines the image quality. Different screens have different light and dark contrasts, and the tendency of image quality is also different. Therefore, we must understand the compatibility of projection screen and projector, the placement position and the influence of audio-visual environment before we can make a choice, otherwise the perfect picture cannot be fully reflected, which is like the importance of speakers to the sound system.

3. Set up the sound system.

Compared with the empty theater, the area of home theater is relatively small and the number of audience is relatively small. If the sound system we choose has excellent performance, it is not impossible to create a perfect effect as long as it is set well. Moreover, in order to ensure the sound output effect, we should also choose high-quality speaker equipment.

Step 4 use the projector well

The effect of home theater is directly affected by the projector, so it is very important to use the projector correctly. When using the projector, we should consider the size of the cinema space and the lighting of the space. If the space in the cinema is not very large, it is best to use a liquid crystal projector. If the room is relatively empty, there is no strong light, and the use is relatively fixed, you can choose to use CRT projector. If we only pursue the uniformity of the picture and the softness of the color, we can consider using DLP projector when it is not necessary to display high resolution. If the requirements for the environment are not high, the display area is relatively large, and the requirements for local details of the picture are relatively high, you can choose to use the LCD projector.

5, layout projection environment

When the projector is working, it should not be affected by too strong ambient light. These strong outdoor light and indoor light will make the projection effect of the projector very poor. We can install curtains in the room to block out the outdoor light. The walls and floors of the room should be made of materials that are not suitable for reflection, because these details will affect the fidelity of video effects; In order to get the best surround sound effect, we should surround the walls of the room with curtains as much as possible; Finally, we should pay attention to one detail, that is, don't sit in a high-backed seat, and don't let the seat be close to the audio equipment or speakers. Too high a seat or close to the sound equipment will make the sound effect poor.
