After the first two articles were published, they were rewarded and answered by many friends. Thank you for your support. The ZDM has hidden tigers, and many of the big gods have seen my problems in the cinema layout. There was no outline written in the article, and one piece was missing in the first article. There are also some friends who are planning to build a home theater and ask me about the specific construction ideas and precautions. These contents are planned to be added in the article. However, the site is set up. Only texts can be added, and pictures and links cannot be added. Therefore, they are updated here.
The theater line must be routed to meet the layout needs after the layout is determined. Many lines need to go through the renovation. This requires that you do your homework before the renovation to determine the theater layout. Before the construction of my house was completed, there was a month's time waiting for the decoration team to complete the project. This month, it played a significant role in improving the conception and layout of the theater. Even so, after the start of construction, we made some changes.
When looking for the theoretical basis for this part of the content, I also found out the articles I read at that time and now I still read and write. The height of the gods, I really can not wait.
For the living room party, we must first determine the distance between the emperor and the curtain. We call this distance the viewing distance. The size of my living room is 4.8 by 4.8 meters. The sofa is against the wall and is calculated at a viewing distance of 4 meters. According to the visual range of the human eye, the size of the curtain can be determined. In this section, I refer to the last532 article in 2014.
Home Theater Development Program Part I: Selection of curtains and calculation of related parameters In front of the words: At the end of last year, the new house was newly renovated, so he took advantage of the depreciation of the yen, defeated an EPSON TW5200 from Japan and dropped 2,000 yen. : Another drop of 2,000 yen: EPSON Epson EH-TW5200 projector (3LCD, 8x, 3D, 2000 lumens, 1080P) 77281 yen (about 5100 yuan) and then dropped 2000 yen...last532| Like 1k Comment 442 Favorites 7kView details Put the above test into the drawing. I don't have complex CAD drawings, so I paint on white paper. Borrowed children's compasses, triangle rulers, round feet and other long-lost tools.
According to Dolby's speaker placement requirements, then put the speaker position into the drawings. Because there is a sky speaker, but do not want to use JBL Control 1 Pro this box-type speaker, it is necessary to take into account the ceiling, which involves beautiful. In this way, the specific planning and layout are basically determined. Then, based on the product description of the speakers to be purchased, it is feasible to determine the distance from the wall.
The next step is to determine the projector based on the viewing distance and the screen size. My projector is a BenQ W1070+, and the distance needed to project 150 inches is 3.39-4.40m, just for me. In June last year, the principle of early buying and early enjoyment, 5,400 yuan was purchased from Jingdong. The whole family only occasionally saw the rainbow.

BenQ Projector Calculatorprojectorcalculator.benq.com Direct Links According to the determined layout, the installation positions of the projector and the curtain are determined. Here we must pay special attention to the hanging height of the curtain, of course, this height is adjustable. BenQ's projector can also be adjusted up and down, but any optical adjustment will bring trapezoidal distortion.
According to the height of the eye sitting on the couch, the height of the center of the curtain is determined. It is not necessary to look straight, there is a certain range of perspectives, and if the range is too high, it is uncomfortable and the cervical spine can not stand (it is not good for a computer to play with the cervical spine). I forgot where I saw this data. Now I go back and find it. I can't find it.
This is the screen size of my curtain, which is derived from the pdf of BenQ. It is placed on the mobile phone to facilitate the decoration workers. The magicdog saw at a glance that my projection was hanging high. It is indeed 8 cm higher than the initial plan. The reason is that there is no suitable TV cabinet. . . My home TV cabinet has been quite simple, it is to fit the center speaker and curtain. Considering that the screen is 50 centimeters from the video wall, it hangs down to the front of the TV cabinet, but its mid-size is too large (21 centimeters high, it can't fit into a TV cabinet with an opening, so we have to choose a flat TV cabinet). The curtain is not a sound screen, and the sound is finished. The sound screen is too expensive, not my food. So you have to hang up to this height. It should be noted that the size of BenQ's calculation does not include the 3-4 cm black border below the curtain. When you use it, it feels okay and you won't feel the curtain is too high.

Second, the theater collocationReally should say that true love wallet away from av199! At the beginning of the year, I purchased the Jamo s606 sets in JD.com with Marantz sr5010. The price was not expensive and I had enough experience. However, the sale of Jumbo really made me angry, and the packaging process directly opened a big hole to see their unreasonable attitude, pull the black and resolutely not buy. For a moment, she also suffered herself. Re-select the speakers, choose not to come out. Posted in the forum, seeking to recommend the combination of speakers below 10,000 yuan amplifier, but the recommendations are starting million. So defeated these few.
The first three are KEF's Q700 and Q600c. There are more flowers and plants at home, and the wife is a flower lover.
The store is too expensive to purchase in Taobao. There are barcodes and serial numbers at the position of the phonetic column. You can log in to the KEF website to register. This can be verified authentic. The boss is very professional and people are friendly and enthusiastic. He also advertises for him here.
Wanli audio line_ Taobao shop search Taobao search is the most intelligent commodity search engine, through the operation of big data, accurate understanding of goods and users, providing accurate personalized search experience. Direct link to shopsearch.taobao.com The surround and sky speakers are magant.
Purchased from Amazon in Germany. Sky speaker is a single pack, do not take my detours. . . .
Magnat Interior IC 62 2-Wege High-End Decken-Einbaulautsprecher: Amazon.de: Audio & HiFi63.99 Euro Germany Amazon Direct Link 
Magnat Monitor Supreme 102, Regallautsprecher, mocca (1 Paar): Amazon.de: Audio & HiFi 96.71 Euro Germany Amazon Direct Link Mi Li did not audition at home and liked him based on videos on YouTube. Actually listening really well. Credit card activities are counted down, and the price is overwhelming.
The power amplifier is Onkyo 656, which is the general agent of Jinan. Because KEF agents do not represent Onkyo, it is not possible to cooperate with Onkyo and KEF. Unexpectedly, the total generation of Onkyo's shop is using rz800 with KEF Q series, the effect is indeed good. The price of the RZ810 is too expensive. In line with the principle that enough is available, the 656 is chosen. The price is cheaper than Taobao and also saves shipping costs. Using it, I felt that Onkyo's voice was what I wanted, and the ease of use of the power amplifier was also very good. This part of the content, then elaborate. The curtain lifts and drops the fine sand (particles on the surface of the curtain). In order to protect the power amplifier, a layer of gauze is placed on it.
Share a few purchase experiences:
According to the budget to determine the goods, do not do super budget things. I was thinking that if the satellite box or bookshelf box was originally chosen, it would be good.
Be sure to audition. The sound of this thing is invisible. Jinan sound shop is rare and scattered. These shops basically run through. At the same time as the audition, the boss will introduce me to a lot of knowledge that I do not understand, which also made me understand more about the construction of the theater. For example, building a panoramic sound is a store sales brother strongly recommended.
The first three are consistent. The first three are the main speakers and center speakers. This agreement is consistent with the brand and the horn. 5.1 Under decoding, the dialogue was sent out from the center, and people often complained that the midrange voice was small and the dialogue was inaudible. I think it may have something to do with the size of the center speaker. The Q700 and Q600c I chose were all 6.5-inch woofers. The relevant data are basically the same. The Q200c center is 5.25 inch bass.
Without auditioning conditions, I'm comparing video on YouTube. YouTube has a video of KEF Q700 and Polk RTiA3. It's much better than listening to kef. It also consolidates my idea of ​​using another brand. But many people still recommend all speakers with the same brand. I didn't try it in this area and I don't evaluate it well. However, all speaker sizes must be the same. My sky horn is 6.5 inches, but the surround is 4 inches. This is the biggest failure, although it can be balanced by adjusting the amplifier, but the result of the balance is to limit the 6.5-inch sound.
Do not take into account. I want both film and music, taking into account the inevitable will not bring movies and music are not outstanding. Onkyo 656 is av power amplifier, music is bound to not work. Imagine that I used the Marantz pm6005 with a surround magnat 4 inch horn to listen to hifi, and also better than the Onkyo 656 with the Q700. However, it is not without a solution. Buy a hifi pure amplifier with a through function (Marlans pm8005 and above) av amplifier preamp output to hifi amplifier, hifi amplifier to connect the main speakers, av amplifier to other speakers. The sound of watching movies is released from the av amplifier, listening to music only opens the hifi amplifier, and hifi drives the main speakers. This is also why I chose the KEF Q700. You know, the KEF Q series is officially defined as HI-FI SPEAKER. This will be a no return, but also to the post, upgrade power amplifiers and speakers. . . To play the sound, it's enough to stop it and sneak it.
The debugging process requires slow work. Projection and curtain hanging up, more than an hour can be debugged, once the debugging does not have to move him. The hardest part of the entire debugging process is the sound and the connection between devices.
The amplifier is the media of video and audio. Be sure to read the manual carefully, download a pdf, and put it on the mobile phone. While reading and debugging, there will be different gains. Onkyo's automatic running EQ, not the same each time, had to make my voice beginners try many times. It now appears that the sound of the entire system is still passable, but it is not at its best. This is not unrelated to the acoustic treatment of the room. I'm still learning this content and I'm not going to make a fuss.
Share a few experiences:
1. When the power amplifier was first adjusted, EQ turned off and saw the prompt on the boot screen. Baidu took a look at the reason. This was caused by the harness. The banana heads were separated by straps and the problem was solved.
2. Amplifiers should be avoided hot swap. Although I pay attention, it is inevitable. There have been a lot of small problems, such as airplay and Bluetooth connectivity is not on; hdmi main output intermittently lost signal and so on. Don't worry if you have problems. Look at the instructions. You can't solve the problem by calling 400. I think that the mechanic at the end of 400 has already remembered me. Many problems are caused by improper settings, not hardware failures. Make good use of factory settings.
3. Make good use of the listening mode. The movie with panoramic sound decoding can use dts:x, stereo old movies with all ch shereo, games and other sound sources can use direct, pure music with pure audio, symphony and opera with orchestra. There will be surprises.
4. Open direct, there is a great deal of use straight. For example, when watching movies on HTPC on TV, if you don't want to use amplifiers to expand, you can put the amplifier on standby, and then the sound comes out on the TV.
In order to simplify the operation, the harmony purchased in advance played a big role. TV, power amplifier, projection, ps4 and other one-button operation. No harmony is harmless because both Onkyo and Kodi support app operations. On the pad, the pad serves as a central medium. Directly using the pad to select a movie, controlling the progress and volume, and the listening mode does appear to be a bit taller. When they showed friends, they were all surprised.
LAN can also use pad AirPlay to power amplifier, listening to music and radio are very pleasant, Onkyo amplifier supports standby start, lying in bed to operate some can listen to the radio.
But at present, both Airbridge and Kodi have poor AirPlay support for ios9 and above, only audio and no video. Looking forward to solving later, movie screening becomes very simple.
Whether it is AirPlay or Bluetooth connected music playback will make the sound quality becomes lower, and lossless playback on the HTPC directly from the amplifier is also achievable. Through the app on the pad, select the music servers and find kodi's open UPnp database for easy connection.
In addition, the application of HTPC is far more than this. Because of the samba share, so in the LAN, mobile phone pad, etc. can be installed VLCplayer to read the shared audio and video data on the HTPC. After the second article was published, a friend introduced using btsync (now religio sync) to automatically synchronize mobile photos to HTPC. However, how to use the external network to access the HTPC is still under study. It is not known which protocol of ftp or LAMP is more convenient and feasible. At this point, three articles were completed. Initiate and attract heroes and hope to be enriched by heroes. (Stiff pillow.. Uncomfortable...)
