Hello everyone! Old age came again The European Cup has opened, and Laoji is also watching his favorite team.
When the night comes, it is too cool to summon 35 friends to sit together and enjoy a vodka whiskey cocktail without worrying about harassing neighbors.
What this brings to everyone is the process of building a KTV audio and video system and home theater installed in the basement.
About the environment: About 60 square meters of the basement (the floor tiles are 600 size), divided into KTV audio and video area, bar area and toilets to facilitate the smooth flow after drinking
The following figure is before the curtain is lowered
Curtain down
Can show a song
You can also use Huawei's network STB to enjoy watching movies and watch the European Cup
The following is the control zone, lounge area and bar area
There is also a bar area next to it.
Let's introduce the device first
The entire basement video system consists of the following components: projectors and wall mounts, curtains, set-top boxes, KTV karaoke stations, amplifiers and wheat machines, audio
The first is the soul core: Projector ViewSonic PRO8200Buy in May Buy May 2015 Recommended
The above is the introduction of parameters. The first thing this machine attracted me was that the price was in line with the budget. Although 2000 Liu Ming was a bit low, but because the basement had only a small window and was also equipped with curtains, it was sufficient. At the same time, it also had an economic model that could be greatly improved. The life of the bulb. Aunt Zhang’s recommendation to buy is also worth more than 70%. So happy to place an order.
If it is placed on the table, you can use the button on the top to operate the projector
Many back interfaces, two HDMI interface input can be switched by a key remote control.
The feet can be individually adjusted for undulating tabletops.
Remote control: You can switch several different outputs with one click
Because the projector needs to be used in a low light or no light environment, the remote control is very user-friendly with a backlight button. Just press once and the remote will light up. Avoid the need to use the remote control but do not see the button
Post-installation effect 
When it was bought, it was 79 yuan, and after one year it was still 79.
When installing the wall mount, first find the wooden ribs in the shed (the best way is to mark the installation position with the installation master when installing the shed).
The rack gave a total of 4 hanging arms, but this projector only has 3 holes. The teacher said that two points were in line and three points into one. It seems that the design lion has a solid grasp
The screws given are long and should be designed to fit deeper screw slots. Fortunately, with a few plastic sleeves to adapt to my shallow groove projector.
A more intimate design is that the projector is connected to the pylon by the buckle through the base of the pylon and is not hard-wired. So if the projector does not need to hang up, you can slide it down with a single press.
Push the white card down to launch the projector
By loosening the screws, you can adjust the height, forward tilt angle and left and right swing
Including packaging, it is about 2.6-2.8 meters long. Fortunately, the rear seat of the old age car can be put down. Just insert the gear from the trunk directly into the gear and let it go.
This curtain is electrically driven. Only need to be energized to easily ease.
Usually do not have to close up
Come down to the guests
Aunt Zhang - I Love You for Ten Thousand Years
The curtain is suspended by making holes in the wall and expanding the screws to ensure a firm connection. The expansion screw is 1 cm of iron to ensure absolute stability does not fall off suddenly (I will not tell you these I used the ordinary household electric drill with a battery instead of a shock drill to drill the hole. The difficulty was not mentioned.)
In order to ensure that the expansion screws are completely safe, the wispy old nails some wood and screws into the gap.
Popular science: The curtain is not a large white cloth, but there are some glassy fibers above it that can make the projected picture more vivid
The feeling of use of the screen: electric retractable is very convenient, if not a small 200 yuan, it is recommended to buy electric. If you don't use it, hanging it there will also put the ash. Ordinarily closing up can also extend the life of the curtain.
Set-top box: Huawei boxAlthough I don't use Huawei mobile phones, this box is really fast. It's much faster than a treasure I bought five years ago. The small box is very small. It's a little bigger than a cigarette box, and the workmanship is also very beautiful. Very heavy.
Bottom of the box, some machine information
The side of the box interface. 1 point 2 output, USB, network cable interface, HDMI interface.
Do important functions have to be written out to see the separate HDMI interface on the right side of the figure? Writing STB IN. What does this do? Simply put, HDMI is a direct connection. Now many people have a high-definition set-top box of the SARFT, so they need to connect to the TV through HDMI. In general, if you want to switch signals between the TV set-top box and the network set-top box, you need to use the TV remote control to select the signal input port.
However, with this Huawei box, you no longer need TV remote control! Simply connect the HDMI output of the TV set-top box directly to the STB port of Huawei STB. When the Huawei set-top box is in power standby mode, the signal from the TV set-top box is directly transmitted to the TV, and when the Huawei set-top box is activated, it will automatically switch to Huawei's output. Very convenient, you no longer need a TV remote! A good kind of Huawei
The interface of the set-top box is very simple, but I abandoned all its functions and installed a TV cat app. This is the king
By the way, the ViewSonic projector comes with a 10W speaker, and Huawei's set-top box can directly play through the HDMI input. However, since I used the 1 point 2 function behind the set-top box to connect directly to the amplifier, I didn't need the little poor speaker.
Amplifier: Shinco KTV Kit
At the time, they purchased a Tmall shop at Xinke, which cost around 4,000 yuan. Including: a power amplifier, a wheat machine, two microphones, a touch screen karaoke device.
Positive power amplifier. Because it's too long, it can only be divided into 2 segments.
The most useful button on the left side above the row of buttons is the input button, which is used to select the input port of the signal. Usually the sound of the KTV and network STB is switched through this button.
The close-up of the right half. Two large knobs adjust the volume of music and microphones. The two golden holes in the lower left are the parts where the wheat machine and the amplifier are connected. 
After the power amplifier is powered on, the button will turn blue and it will be very dazzling. Personally hate this design, I do not know if there is a problem with his own eyes flash, there is such a strong direct light, simply can not see the word on the amplifier.
Two sets of left and right LCDs are used to control the volume of the two microphones.
There are only a few jacks behind and it's very easy to install. Only need to use power and audio output. 
After power on, the screen will light. The two values ​​are the volume of the corresponding two microphones.
Only one microphone is turned on, only the corresponding one will be on.
Wheat machine and amplifier connection: through a long line to connect the wheat machine butt to the front of the amplifier (red line in the figure).
Yes, you read it right. A good amp machine came out flat for no reason. It was such a long, thick line. The whole 13 cells were pulled down. I am still thinking about countermeasures. Planning to buy a L-shaped transmission line 
With its own pylons, only a few holes in the wall can be used, and expansion screws can be easily used to fix it. There is no need to hire plumbing personnel!
Behind each audio only need to insert two interfaces of an audio cable, no external power supply
Two acoustic audio cables are put together at the corner of the wall and passed through a PVC pipe on the wall, which is connected to the back of the amplifier.
Because I used the set-top box and the KTV jukebox for two audio inputs to the amplifier, I used two of the three groups of audio inputs. Therefore, in the process of using the power amplifier, it is necessary to select the audio input through the input button described above and select the correct audio input hole so as to correctly output the audio channel sound.
Being pitted : The first time the Shinco Jukebox gave me the feeling that my time was flowing and I was back to my youth that would not come back. It reminds me of the sunset.
Talk about people ------ operating system ten years ago
The photo was not taken. Contact the customer directly to ask for a full refund without consulting. This device is simply to let others see jokes. Dog Jade's new customer service is not good at sighting, directly offering big tricks. ----- Tell me that the store has recently been on a brand new system, but it has not yet officially opened. It is only necessary to mail the hard drive back to me. A hard disk with a new system can be installed.
It is true that the tree is not repaired or straight, and people do not repair it. I don't know how many customers have been used but have endured.
I think it is acceptable to replace the system. And there is the function of network transmission song. The KTV machine is connected to the home wifi network through a USB wireless WiFi module. If the latest song is not found in the jukebox hard disk, then if it can be searched on the Internet, it can be song-like. Will automatically download to your hard drive.
In order to avoid too many guests and miss the situation of the karaoke machine, the machine also added a mobile phone song function. Unless you are using APP, you can use WeChat's sweep to enter the song page.
Each function of the VOD Web page is very clear. Even older elders can easily use mobile phone songs.
The entire system is also very smooth and does not stall. As you can see in the demo video, I have no obstacles in sliding or touching. The page is manipulated in the background and the system can also be set up, as well as the network connection page. As long as you have connected to the Internet, you can download the songs in the network library!
Microphone: The power consumption is very low, and a quarter of a Huatai battery can be changed for a long time
Summary: Although the old age when singing "When I miss you" often appears to be misunderstood that the original tone does not pass, but still do not come out ugly. There are too many gods and gods. If Wang Feng is also, isn’t it
This set of KTV equipment feels a bit out of place in this basement. However, because the buying time is a little early, so it can only be this way. After all, you can't buy new ones for no reason. The landlord's family has no surplus food.
Although a set of video and audio devices may seem complicated and require many things to buy, as long as you read the instructions carefully, you can successfully assemble successfully! If you are a friend in a residential building, to avoid complaints, it is recommended to install soundproofing! Harmonious community environment requires you and me to maintain together! Because there is no neighbor next to the basement, and the usage rate is not high, no sound insulation is installed.
European Cup is getting hotter! I hope everyone can see the European Cup!
Thank you all for watching and give a reward
