[Home Theater Network HDAV.com.cn] For most ordinary families, home theater is usually limited to the size of the home, the home theater is usually placed in the living room. Of course, there are also some friends with better home conditions, can provide a separate room as a dedicated audio-visual room. However, compared with professional audio-visual rooms, due to the limited budget for decoration, it is generally not subject to professional treatment such as sound insulation and sound absorption.
The rookie's hairpin home theater is set up and decorated.
Although a lot of renovations have been omitted, it is still necessary to make renovation plans in advance. At the same time, for families that have already been renovated, there are also some ways to solve the problem of projector installation. I believe that through the introduction of this article, you can get some information with reference value.
Decoration wiring articles: arranging audio cables and power outlets
If the home is going to be renovated and there are plans to set up a home theater, then you must pre-lay the audio and video cables and power outlets before the renovation, so that there will be no clutter in the future when you add projectors and speakers.
Cabling requires pre-planning
At the beginning of the renovation, in addition to planning video lines, audio lines, and signal lines, you should also reserve power outlets for the projector and electric screen at both ends of the sofa wall and screen wall. It is worth noting that the power cable and the audio and video cable cannot go through the same conduit, and the installation position of the audio and video cable and the power socket should be determined in advance.
Ground again
After all the wires of the wall and the ground are connected, the wiring work is basically completed, and finally a layer of cement covering pipe is added to level the ground. In the decoration process, we only need to confirm the position of the wiring and power socket in advance, and the construction can be handed over to the foreman.
Decoration and wiring articles: arranging wire troughs to solve the problem of open lines
For the refurbished living room, it is obviously impossible to use the above method to hide the wiring. In this case, the cable trough is needed to solve the wiring problem of the audio and video lines. It is worth noting that since the wire slot has various specifications, including length, wide screen and thickness, it is necessary to match the wire grooves of different specifications according to the thickness of the wire.
Solve the open line problem with the wire trough
The wire trough is arranged at the edge of the window and the lower edge of the wall, and almost no influence is observed. Finally, the power amplifier, the player and the projector are respectively connected to both sides of the screen and the sofa wall. In general, voice and video lines that are not in a fever are placed in the same slot without significant interference.
Projector installation location bare wire
On the wall where the projector is installed, since the video cable and the power supply are not pre-buried during the decoration, the overall aesthetics will still be affected. In addition, since the electric screen needs to reserve a power outlet, the renovated room is more suitable for a manual screen without a power source.
Projection installation articles: the most commonly used for front projection and ceiling installation
The importance of wiring was mentioned before, but the position of the video cable and the power interface on the wall is determined according to the installation position of the projector. Before the decoration, it is necessary to calculate the installation height of the projector according to the projection ratio, offset, and screen size of the projector. During the installation process, the projector has two most common installation methods, one is the ceiling installation, and the other is the front projection on the pallet.
Ceiling installation
Ceiling installation is the most common installation method of the projector. When installing, the projector should not be close to the wall, leaving a gap for connecting the video cable. The distance between the projector and the screen needs to refer to the specific parameters of the projector. When installing the ceiling, the height of the projector should be generally 1.7 meters or more to ensure that the bottom edge of the projection screen is 0.6-0.7 meters to the ground. In addition, the projector hanger will provide a range of expansion and contraction, which can reduce the installation height of the projector when the projection screen is too high.
Pallet
In addition to the ceiling installation, the projector is placed in the front of the pallet is also a relatively simple installation method, but due to changes in the projection mode, the installation height of the projector is only about 1-1.5 meters from the ground, the noise generated during operation The hot air may affect the viewing atmosphere.
Projection installation: displacement and short focus highlighting practicality
In addition to the two installation methods described above, there are some relatively small projection methods, depending on the function of the projector.
Side projection with lens shift
If you don't want to ceiling or install the projector with a pallet, consider splitting. With the wide displacement function of the projector, the projector can be placed on the side table or professional equipment rack next to the sofa, and the projection screen will still be displayed in the best position. However, while we are getting convenience, we also need to increase the budget for purchasing equipment, because the price of home projectors with displacement function is generally more than 15,000 yuan.
Short throw projection is very convenient
If the above solution is out of budget, choose a short throw projector that is more suitable for small spaces. Since the short-focus lens is equipped, the projection distance is reduced by at least 50% compared with the ordinary projector, so there is no need to consider the installation problem of the projector, and it can be placed directly on the coffee table when in use. At present, the resolution of mainstream short-throw projectors is SVGA, XGA, and WXGA. There is no short-throw projector with 1080p specifications.
Screen installation: electric screen and manual screen
Introduce the installation method of the projector. Here is how to install the projection screen. If the home theater is placed in the living room, you will definitely encounter the problem of installing a flat-panel TV and a projection screen on the same wall.
Flat wall + electric / manual screen
At this time, the best solution is to mount the flat-panel TV on the wall, and the projection screen is installed on the wall. If the power socket is reserved for the projection screen in the early stage, you can choose to install the electric screen; if there is no power socket, select the manual screen.
The picture frame screen is very beautiful
In the double living room or the independent video room, because there is no problem of coexistence of TV and projection screen, the best choice is undoubtedly the frame screen.
Details of the problem: power socket / curtain / screen height
When arranging a home theater, there are many details to be aware of, including not only the location of audio and video cables and power outlets as mentioned above, but also the shading, the height from the ground after the projection screen is lowered, and so on.
Power position of the electric screen
During the renovation process, the power outlets for the electric screen are usually missed. At this time, we can only passively choose the manual screen and the frame screen.
The curtains are still thick.
Although the brightness of mainstream home projectors has reached more than 1500 lumens, in order to create a better cinema atmosphere, thick shades are still a necessity, reducing ambient light is very helpful to improve the picture quality, especially the black level performance.
Screen and center speaker position
In general, whether it is manual, electric, or frame-screen screen, the screen is most comfortable to view 0.6-0.7 meters below the ground, and the center speaker is installed just below the edge of the screen.
Written in the end: In a simple home theater design, because the wire position, power position and projector performance and home environment are closely related, it needs to be considered in all aspects. If you are planning to set up a home theater, you may want to choose a reasonable projection method based on the actual home environment, and then plan the wiring.
