build a home theater. The one that is recommended by friends is Sony . Especially for TV products, many friends say that Sony is necessary. This feeling will be particularly obvious when comparing Shundian and Suning stores. Recently, a Sony home theater was built for a promotion. I took this opportunity to share my own strategy, hoping to help everyone get it.
PS: Follow me! Get updates on filling holes as soon as possible. Everyone’s attention is my motivation to fill the hole.
TV Preparation Guide
In terms of technology flow, Sony is the originator. In terms of TV alone, there are XR cognitive chips, XR Terry Charming Pro, XR Octavia Dynamics, XR 4K times the cable, etc. The most important thing is that the system is clean and ad-free, and it does not restrict everyone from installing third-party APPs. It has high freedom and feels that the user experience is the benchmark for TV products.
- prefix letters: KD is X1 chip, XR is XR cognitive chip.
- prefix number: represents the screen size, 65 means 65 inches.
- middle letter: represents series, A is the Oled TV series, W is the 2K TV series, X is the 4K LCD TV series, and Z is the flagship series of
K resolution . - Number: The larger the number of ten digits means the higher the TV, and the larger the single digits on the basis of ten digits, the higher the higher the; if the model is only single digits, 1 and 9 represent flagship TV.
- ending letters: represent the year, H is 2020, J is 2021, K is 2022, and so on.
The general naming rules of Sony TV are as above. I simply recommend some cost-effective models for your reference (mainly discussing from screen technology, without paying attention to Android hardware configuration).
The budget is relatively limited and I want to buy a Sony TV. You can buy the KD-55X80K with IPS hard screen. Although the 80 series does not have a light control partition, it is equipped with Sony's exclusive X1 chip, Terry Color Display Technology Pro technology and space balance speakers. Purchase this TV to experience Sony's excellent picture color and sound performance, and also experience a pure TV system. Recently in promotion, pre-sale price of 4999. If you post a order, you will get 100 E-cards, which is equivalent to 4899.
0 series also has good prices, such as XR-65X91J. VA soft screen, supports XR cognitive chip, XR contrast enhanced advanced version and multi-channel screen sound field, allowing you to fully experience Sony's image quality and sound effect technology. Due to the launch of the new generation X90K and X91K, X91J is in a big promotion recently, with interest-free 24, and the price is 5,999.
If you want to know the cost-effectiveness, you have to recommend the VA soft screen XR-65X91K. It is officially promoted that X91K is an upgraded model of X91J, but it is more like the light control partition technology of the previous generation X95J (60 pieces, 75-inch 84 pieces, 85-inch 112 pieces). In addition, there is an enhanced XR chip, 1000nits brightness, supports full 4K 120Hz, and if there is a Sony PS5, there is also a picture quality bonus.
for large screen experience, X85J has become the first choice for large screens for many fans. VA soft screen, 4K 120Hz screen and supports Motionflow XR technology. The disadvantage is that there is no partition control, but the price is cheap. Currently, it can be interest-free for 24 periods, with a purchase price of 10,999.
stereo surround sound recommendation
to build a home theater. In addition to TV, there must also be a set of stereo surround sound speakers. Sony has a very profound attainment in audio technology, with interfaces, support formats and space technology, .
has a limited budget and can choose the entry-level HT-S40R. Although the HT-S40R function experience is relatively basic, it comes with a subwoofer and rear surround sound. The physical 5.1 channel can bring an excellent surround experience. What's more important is the convenience of connection. The rear surround sound is equipped with a wireless receiver without connecting to the front main body through wired. HDMI ARC, optical fiber, 3.5mm stereo interface, and Bluetooth functions are all equipped, and you can connect to the wireless experience through Bluetooth and Sony TV.
Low budget and want to have Dolby Atmos and DTS:X, then you can choose HT-G700.The 3.1 channel can make the sound clearer. Sony's exclusive immersive surround audio enhancement experience. One-click turn on makes the sound not only surround but also feels high, which can bring a surround immersion experience.
has a wealthy budget, and it must be a classic combination of flagship echo wall HT-A7000+SW3 subwoofer+RS3S rear surround speaker , with 360 space sound field mapping technology and sound field optimization technology. I felt quite shocked when I listened in the store.
flagship home audio and video system HT-A9+ flagship subwoofer SW5 combination is a popular combination of Sony this year, promoting the ability to realize 12 phantom speakers with 4 surround speakers, realizing the live feeling that it feels like being in person. However, the firmware update in the early stage was slow, and there were some problems. As far as I know, it has improved recently. During the 618 period, not only did the price reduction promotions, but also provided free door-to-door installation and debugging services, which felt good.
Home theater building record
After some comparison, I finally bought XR-65X91K. The speaker was originally planning to buy a pair of Hi-Fi speakers, but she couldn't resist her family's ideas. She found out from the store experience that she bought the dual flagship HT-A9 home audio and video system and SA-SW5 wireless subwoofer for this.
speaker layout
The traditional surround audio layout emphasizes angle and positioning. Many old bacons have had this experience. The sound is very wonderful and moving when you listen to it on the spot, but it becomes a bit scent when you buy it home. This is the difference caused by positioning.
Sony HT-A9 built-in microphone measures the distance between each speaker and the ceiling, and can easily complete sound field optimization without additional equipment. Equipped with 360 space sound field mapping technology, it is Sony's unique unique sound field restoration technology. It can build 12 phantom speakers that can make real sound sound in the use space. It can create a wide sound field area with a larger real space than the actual space where physical speakers are located. I always have a "immersive" feeling when using it, and the immersion is full.
So Sony HT-A9 no longer has such high requirements for positioning. I am really novice and can’t do anything. Moreover, starting from May 26, for users who purchase HT-A9 and HT-A7000, they can make an appointment for Sony’s safe installation service, and professionals will come to install and debug for free.
As Lao Shao, there are still some doubts about Sony's sound field optimization, so I first carried out the traditional positioning. Let’s take a casual position and see if there are any differences. When setting up a home theater, the main reference is the standard of ITU (International Telecommunications Unions).
center speaker is placed in the center, and the Sony HT-A9 uses a TV speaker as the center, so this placement process is skipped.
The speakers should be placed at 22.5-30 degrees with the throne of the emperor, and I can only take 30 degrees in a small living room like my. The left and right channels speakers are placed next to the TV. According to the triangle Pythagorean theorem , the throne of the emperor will be 1.48 meters away from the TV.
Sony HT-A9 is designed with a very careful design. At the bottom of each speaker, there are graphics that intuitively display their placement position to avoid user errors in placement.
According to the throne of the emperor, draw a circle with a radius of 1.52 meters. The left and right positions are 100-120 degrees. The rear surround is located. My living room is relatively small, so I chose 100 degrees as the placement position. The positioning of the
SA-SW5 subwoofer is relatively free, just place it on the left or right of the circle. Some enthusiasts said that it would be more appropriate to put it on the right than the left. I have tried it myself and there is no difference.
line building
. The difference between the previous home theater products is that the Sony HT-A9 and SA-SW5 subwoofers are wirelessly connected, saving a lot of wiring troubles. The 4 surround speakers and subwoofers will be connected to the central control small box wirelessly, and the central control small box can be connected to the TV.
After the connection is successful, a green light will be displayed at the bottom of each speaker. I saw many people on the Internet saying that HT-A9 will be disconnected, but I tried it myself without any related problems. Please refer to the installation instructions of the official website and do not get close to Wi-Fi routers, microwave ovens and other radio wave interference sources.
says that Sony TV is the best match for Sony audio because Sony TV has the function of BRAVIA mid-mounted sound field synchronization mode.
When the Sony Audio is connected to the TV, it will automatically recognize the home theater product and have relevant setting function options.
Through the TV, Sony audio can be automatically set or manually set.
In the TV settings, the speaker will become a sound system. Increased subwoofer volume, bass volume, rear speaker volume adjustment, etc.
also has a home theater setting page, which sets the audio mode of HT-A9 separately.
As the center channel function, this TV is to retransmit the center sound in the speaker to the TV output. In the interface of the Sony HT-A9 central control box, there is a 3.5mm mid-mounted sound output interface marked with S-CENTER OUT.
In the back interface of Sony XR-65X91K TV, there is also a 3.5mm mid-sound input interface marked with the S-center speaker input. You can use the TV as a mid-mounted speaker by just connecting the cable to a 3.5mm interface.
Sony TV is a full series that supports eARC, which is an advantage over other brands of TVs. eARC and its predecessor ARC have actually been released for many years, but few people know about it, which has to be said to be a pity.
does not support connection between ARC functional devices and Sony home theater products, and the input and output are unidirectional. For example, if you have a Blu-ray player and a TV at home, the output HDMI signal of the Blu-ray player must be connected to the Sony home theater product first, and then transmitted to the TV.
If the eARC/ARC backhaul function is supported, it can also add a line from the Blu-ray player to the TV. The output of the Blu-ray player can directly transmit the TV and then transmit Sony home theater products. Or pass it on to Sony home theater products and then to TVs.
where eARC is an enhanced ARC with higher bandwidth. Compared with previous generation ARCs, lossless 5.1 or 7.1 audio transmission can be achieved. In addition, Dolby TrueHD and DTS:X support is added to enjoy a better surround sound experience.
Through eARC, you can also control the functional settings of home theaters. The Sony HT-A9 comes with a remote control, but I put the remote control of the speaker in it. With the eARC function, you can watch movies every day and use the remote control of the XR-65X91K TV.
In the HDMI interface program of the TV, the setting function options for home theater devices can also be enabled.
For example, set Bluetooth , set linking method, connect to home WiFi, upgrade firmware, etc.
also manually connects each surround speaker and subwoofer . By default, it is automatically connected. After changing to manual, you can pair and connect speakers one by one.
Press to start the manual link, and the HT-A9 central control box will enter pairing mode. If the speaker is placed farther, it is recommended to change the wireless playback sound quality option from sound quality to connection.
Then press the link button on the bottom of each surround speaker, and the back of the subwoofer. At this time, the TV will display the connection status of each speaker, and all of them will be identified and connected in a short while.
I have a small discovery. After pressing the Link button of the speaker, the speed of "connected" is displayed on the TV, which is the feedback on the wireless connection signal of the speaker. If the display of "Connected" is slow, it means there is interference nearby, or it is too far from the central control box, and adjustments must be made.
Using experience
In order to play Dolby Atmos, Sony XR-65X91K TV also needs to make some settings. For example, turning on Immersive AE (Immersive Audio Enhancement Engine) can increase the surround feeling in the horizontal and vertical directions.
In addition, if the video you are watching supports Dolby VisionDolby Vision, modify the "External Input" settings in "Settings" - "Channel & Input".
In the HDMI signal format, change the source from standard to Dolby vision. If it is PS5, it is recommended to change to VRR.
Currently, most of the streaming media of Sony TV are collaborating with Tencent Aurora.
In IMAX or Dolby sound effects section, you can experience the Dolby sound effects like cinemas.
As a NAS user, I am more accustomed to installing Kodi's Dolby sound version Kodi Matrix 19 final with Dolby Vision MKV and Libbluray support on my TV and connecting to NAS to play Dolby sound videos.
KODI also requires some advanced settings, such as enabling the support of AC3, E-AC3, DTS, and DTS-HD sound effects in the audio.
channel can be changed to 5.1 or 7.1, both options are OK. Regardless of whether the original soundtrack is 5.1 or 7.1, Sony HT-A9's 360 space sound field mapping technology will be automatically optimized to form a 7.1.4 channel surround effect.
917 is a movie I have been savoring recently. It is a pseudo-long shot movie. It uses special effects to edit multiple clips together, giving people a sense of déjà vu. The SA-SW5 is equipped with a 180mm woofer with a power of up to 180W. In war films and other scenes, you can experience the rumble of artillery fire on the battlefield in an immersive way. 360 space sound field mapping technology, you can hear shouts and painful shouts intertwined around you. Coupled with one shot, it feels very realistic.
The Marvel series of movies are basically a must-have in home theaters. Although the plot is old-fashioned, the special effects and sound effects of various explosion scenes and fighting scenes are top-level.
Black Panther spacecraft flying, you can hear the feeling of spacecraft slowly flying forward from behind. At first I was worried that the living room was smaller and the walls were not absorbed, so that the standing waves of multiple speakers would be more, which would affect the performance of the 3D surround sound field. After actually feeling it, I found that I thought it was too much. Sony's audio engineers probably had related considerations and made optimizations.
In the fight scene of Doctor Strange, when the bus is thrown over and cut in half, the sound of metal being torn can be clearly heard. And that sensational vibration makes people feel empathetic to being Doctor Strange and fighting back.
Remove the special effect screen, the performance of vocal comparison is not weak. It gives me the feeling that the sound field is very wide and the sense of space is also very good. The characters in the movie are like having a conversation in front of me.
This feeling will be particularly obvious when you appreciate a concert that supports Dolby sound effects. The audience's cheers surround you with your ears, and it feels like you are in it. Taylor Swift 018 Reputation tour concert large and large stages, X-shaped main stages, and giant installation lighting effects are all very cool. The Sony XR-65X91K also showed off that gorgeous scene, and the scene was full of infectiousness.
postscript
is used, and the full home theater combination such as Sony XR-65X91K plus HT-A9 and SA-SW5 gave me a great viewing experience. XR Terry Charming Pro supports excellent pictures; HT-A9's unique 360 space sound field mapping technology, like immersive surround sound effects, is not inferior to cinemas at all. Unfortunately, the PS5 at home was broken because I installed the learning version of the game. During the re-repair, I couldn't fully experience the fun brought to the game by Sony XR-65X91K content adaptive image mode, HDR automatic mapping function and high brush and low latency. I'll get back to repair the PS5 later, and I'll share my experience with you.
