First on the shopping details:
Total cost: 10,234 yuan. The original can be more provincial, and later a little episode, slowly behind.
First, choose the installation programThe newly renovated three-bedroom and one-bedroom house has even a small study room that has been transformed out of the balcony. There are no extra rooms for the audio-visual room, so like most people, the projection is placed in the living room. The living room has a rectangular shape of 5.2m4m. It has a regular shape. If there is nothing tangled, put the projection in the middle of the living room. There are two installation options. One is to put the amplifier on the front of the TV cabinet. The other is to put the amplifier next to the back sofa.
Although the two solutions only have different amplifier placement positions, they bring complete differences in line installation. Because the amplifiers are input and output devices, all lines must go through amplifiers.
Solution One: Advantages: The HDMI cable is shortest, and the cable is easily hidden next to the sofa. Disadvantages: The amplifier and player are not suitable for operation on the side of the remote control. The TV cannot be connected to the amplifier.
The advantages and disadvantages of Option 2 are the opposite of Option 1. First of all, HDMI cables consume more than 15M signals, and special lines are used. The price is also very expensive. Secondly, in order to walk HDMI, it is necessary to run underground, and a pipeline with a diameter of 5 cm is buried, which has an impact on the floor tiles and the tap water pipeline. Therefore, the choice of option 1 is not only economical, but also easier to route.
Second, the projection cloth1. Projection fabric material selection
At present, the most cost-effective is the glass fiber material: white glass fiber and gray glass fiber. The fabric is a base fabric woven from glass threads and the surface layer is coated with PVC material with special projection effects. Because of the support of the fiberglass backing, it does not need to be flattened and the natural stretch will be straight. Its greatest advantage is that it can remain flat even when the temperature difference and climate change are large. Due to the role of fiberglass bottom cloth, gain and contrast increase. The white screen has a bright color and the gray screen increases the contrast. The past projection equipment is bright enough, and if the contrast is not enough, a gray screen will be selected. At present, most high-definition projection equipment is faithful to true colors, and the new generation of high-definition projection equipment itself has enough contrast, so choose white glass fiber.
2. Projection cloth ratio and size
Family use will not use the ratio of 4:3 business and education, choose a 16:9 ratio, meet the needs of most families, and leave a black border when playing a 21:9 ratio of movies.
The projection size is as follows: (mm)
80 inch 1771996 100 inch 22141245 120 inch 26571494 150 inch 33211868
The choice of projection size is not only based on the size of the home but also on the projection capabilities of the projector. 120-inch can meet the requirements of my home installation size, and 120-inch is the largest size that most entry-level projectors can project. So choose 120 inches absolutely right.
3. Projection cloth purchase
Hongye is the brand I only know about the curtain. Seeing the price of Jingdong can only be sent to Taobao. When searching Taobao, knowing that the spread is so much, no matter how genuine the seller is, he has a bottom in his heart and is definitely fake. But can not resist the temptation of price, Taobao.
The remote controller is a gift. You can also study the projection bracket and study it together. It is Debon logistics. The seller also provided several logistics options, choosing Debon because Debon is 2 kilometers away from home. The curtain plus packaging was three meters long. At that time, I had to drive it. This length was a nightmare for the sedan. Moreover, the back seat of my car could not be extended to the trunk. Therefore, one can only rely on the driver's seat window, one behind the driver's seat window, but also extended some distance outside the car. Fortunately, Debon's arrival at home is only a remote road and generally there will be no traffic police. Three meters after arriving at home was a nightmare for the elevator. Thanks to the lift being high enough, I didn't have to carry the curtain to climb the stairs.
4 projection fabric installation size determination and installation
I am using a hidden way to hang the projection cloth. If I hang it directly on the wall or ceiling, I just need to leave two hooks. If you want to hide the projection cloth in the ceiling, you must understand the size of the projection cloth, as well as the thickness of the TV wall or placement, so as not to interfere.
The size of the projection cloth, if the ceiling is too high, please ask the seller to add the length of the black side, of course, to add money. If the ceiling is too low, the projection cloth can adjust the amount of protrusion of the black border. The following installation uses the projector cloth I purchased as an example.
There are two ways to hang the projection cloth, one is the mounting hook, and the other is the wall mounting code. Because of the limited space, the hidden code is basically not hung with a wall-mounted installation code, and it is easier to hang with a mounting hook.
The length of the projection cloth cover is 2.98 meters, and the hook is on the edge of the projection cloth, so the spacing of the hooks can be 2.96-2.98m. The following is the installation method. I did not use a carabiner and I hang it directly on the hook.
After installation, the lower end of the projection cloth is 15 cm from the top, leaving a groove depth of 14.5 cm. The projection cloth shows a little, but it is not very obvious. If the conditions permit, the groove depth can be deeper.
TV background wall to hang TV, projection cloth as far as possible outside. It is also necessary to consider that the ceiling of the lamp strip is too wide to affect the appearance and space for the spotlights is left. Therefore, a space of 10 cm is left in the inner wall of the measurement, and the depth of the projection groove is 13 cm.
The length of the projection slot left only a gap of 4cm left and right. Originally, it wanted to stay as little as possible. However, it was difficult to actually hang the projection cloth and the hand could not reach in. So it is recommended to leave 10cm left and right more appropriate.
This operation box is a remote control receiver, hidden in the gap, playing a 5cm round hole on the edge of the ceiling, and the light is also put on such a large empty space, and the power is hidden on the light strip. The power supply of the projection cloth and the power supply of the projector are common, and there is a switch at the bottom to control both power switches at the same time.
Say your TV official outlet is a pit, especially thick. 14cm after the TV hangs up. After buying a TV, there are LG's, only 6cm, or the exhibition hall rack, actually thinner.
Fortunately, the projection cloth was placed 16cm from the wall. Just did not interfere with the TV.
Projection cloth experience summary:
Projection cloth is the simplest device in home theaters, but the installation is the most complicated. At the electrician stage, the lines are well-designed, the lines are reserved, and all dimensions of the projection fabric are studied at the carpentry stage, leaving enough space for the projection fabric. For the white glass fiber brightness and color performance is still very good, but a long time the edge of a bit curled, affecting the edge projection effect.
Third, the projector1. Projector selection
The quality of the projector affects the entire home theater experience. Since the entry level optional is also very few, basically in the BenQ W1070, W1070 +, Epson TW5200.
W1070 projection distance and parameters:
Projection distance: 80 inches 2.02-2.63m, 92 inches 2.32-3.02m, 100 inches 2.53-3.29m, 120 inches 3.03-3.94m, 133 inches 3.63-4.37m, 150 inches 3.79-4.93m.
For W1070, W1070+ is upgraded on the basis of W1070. The upgrade content is as follows:
Quoted from the value of Friends of the sun single
TW5200 parameters and projection distance:
Regardless of the parameters, the main difference between the two models is the projection technology. The W1070 uses DLP, while the TW5200 uses LCD technology. Simply put, DLP will be a bit better than LCD color in the same level, and will be better than LCD in the presence of light. However, some people in DLP will have rainbow eyes. See a rainbow projected in a scene. This is a personal situation. I have no rainbow eyes.
The TW5200 released a record low, reaching 3,700 yuan, but it would be worthwhile. After two days of fighting, all kinds of climbing walls, and finally registered verification code, this site only supports IE and finally orders. Then there was a problem with the credit card information as a single cut. At that time, he was guilty and gave up.
Come two months and release the new low price of W1070+ Amazon 5998. Decisively start.
The current Amazon price is 5799
2. Projector installation
There are two types of projector hangers, all of which can be tilted up, down, left, or right.
The first advantage is that it can be adjusted before and after, beautiful, and the disadvantage is that it can only hang the wall.
There is no other first kind of beauty, and the adjustment before and after the adjustment is very small. However, it can be wall mounted or suspended.
When installing, note that the center of the bulb must be aligned with the black and white borders of the projection cloth in the up-down direction and the center of the projection cloth in the left-right direction. The W1070+ supports side-shooting and up and down corrections, so it doesn't matter if it's a bit closer.
Look at the location size:
About the trace: Mainly the power cord and HDMI cable. The power cord can be reserved for outlets, and my HDMI cable and power cord are reserved for electricians. It is said that the HDMI cable is easily damaged, so it is recommended to reserve two.
After the installation, the main settings for the projector are trapezoidal correction and flip-chip selection. The rectangular grid can be projected for setting reference.
Remote light evenly.
The overall effect of the projection is still very good, the screen shot for a few to enjoy:
Projector usage summary:
W1070+ has left and right corrections to support side projections, and is also suitable for projection in rooms. The color effect is also excellent. I haven’t seen rainbow eyes for so long. When you install it yourself, you need to calculate the installation position with the center of the projection bulb. The best results have been achieved.
Four, speakers and power amplifierSound in line with the principle of listening to the sound of the following million, the lower the price the better, the speaker must have floor speaker. Although also struggling for a few months, eventually bought the Yamaha RX-V377 amplifier plus Jambo S426 kit. Because it is cheap, it looks good.
Jingdong link:
Positive button operation, the button is relatively stiff, and the volume knob has a damped feel
The upper heat sink can see the circuit board inside, which is a sense of science and technology, but it is also a dusty place.
On the back of the wiring, the main five speaker cables are respectively connected to 5 speakers, and two HDMI are input and output.
There are five speaker lines at the amplifier, and HDMI does not use a connector. It directly drills holes in the white panel, and the cable passes through the hole and is connected to the amplifier.
HDMI is the Green Alliance 8 meter, version 1.4. Alloy reinforcement head, metal woven mesh, copper core wire. The price is still quite high.
Wiring at the TV wall, two floor main speakers and one center speaker. The speaker seat is calculated by mistake and bought less. It also uses a white board to make a hole and directly connects to the center speaker.
Incidentally, TV wall sockets have left a total of six, one closed route, one network cable, two speaker cables, and the remaining two sockets. Sockets are not enough. There must be at least eight outlets left on this side.
Amplifier experience summary:
Although there is no wifi but you can use USB to connect iPhone to play iPhone music, it is very convenient to use. Extra Bass technology provides extra bass for the speakers, which increases the bass of the speakers without using a subwoofer. Although it is entry-level support for 4K is also indispensable. It is a bit weak in the surround sound.
Speaker Jingdong link:
Before seeing this suit, he didn't know what brand it was. Afterwards, he checked out the old Danish brand and started off cheaply. The suit has two main speakers, one center and two surrounds.
Technical Parameters:
Great factory style, workmanship is nothing to say. As for sound effects, the bass still needs a subwoofer, and the surround sound is a bit weak, but for the entry level, it is still possible.
Taobao buy surround speaker brackets, sofas in the bottom, so buy a bracket bar speaker turned to the person, do not know if this is right.
Speaker Experience Summary:
This is the first set of home theaters, which are mainly fancy and bought. The downside of online shopping is that they cannot listen to their voices in the field. Although the speakers are lacking in bass and surround, they are generally quite satisfactory. The overall performance of watching movies has a shocking sense of the cinema, but the effect of listening to music is unsatisfactory.
V. SummaryFor the entry-level home theater, the equipment selection mainly depends on the cost performance, and more experience is spent on the installation of the equipment. Installation size calculations and circuit pre-embedding must all be done during the renovation of the electrician stage. It is mainly the choice of projector and projection cloth, and the psychological dimension must have a bottom.
PS, for the curtain fabric, when the tangled or not to install blackout cloth, but for the sake of beauty, or give up. As a result, there are few people at home during the day, usually only have time to look at the night, and curtain fabrics can cover 80% of the light, and the BenQ W1070+ works well in the presence of light.
