statement

This experience is not a Bible, not a truth. All content and opinions are based on low budget and low-end requirements. It is not a general experience of audio-visual enthusiasts and fans. Disregarding this premise and out of context is likely to cause misunderstandings, so the content Understanding, always keep this in mind, some of the specific issues involved will be briefly explained in the article, you value friends based on this experience, combined with their own needs and the actual situation of flexible understanding. It is not easy to write this long series of experiences. It is not easy to raise individual (YOU) (CAN), expensive (YOU) hand (UP), and not (NO) to (CAN) to (NO) true (BB).

Before the opening, I will first give a range of target groups (audiences) to which this series of experiences points:

If your situation meets any of the following, then you can close this experience:

1, already has a home theater

2, audio and video enthusiasts, set up or upgrade home theater just "play"

3, there is an independent video room,

4, home theater budget is much larger than 1W yuan

5, sensitive to factors such as picture and sound, and have higher demand than ordinary people in this respect

6, equipment party

7, plus money party

8, you don’t need to think about money

If you have an intention to set up a home theater and your situation meets any of the following three or more, then I believe this series of experience will help you more or less.

1, like watching movies

2. Little or no understanding of home theater related knowledge

3, the budget for setting up a home theater is not much, 1W yuan or less

4, no independent video room, want to superimpose home theater function in other functional areas in the family

5, has been renovated, do not want to set up a home theater for major engineering changes

6, The demand for building a home theater is not very strong, but if the cost is not high, it is not too much trouble, but also willing to try

7, there is a basic need for viewing experience, but it can not reach the level of sensitivity or fever

—————————— I am the dividing line ------------------

0.1 Why Build a Home Theater?

The author himself is not a videophile, not a player, but a person who likes to watch a movie, has a certain pursuit of watching the movie, but it is far from reaching the level of fever. Moreover, I didn’t even think about going “fever” to “play”. I just wanted to create a set of home theater that meets my own requirements in the shortest time, with the least effort, and with the least money. An An focuses on the most basic thing of “watching movies” instead of “playing”, tossing equipment, and pursuing the ultimate “parameter”. For audio and video equipment, I may be unprofessional, there is no more home theater sound, optical knowledge, but I will not deny that "higher, more expensive equipment, and spend more money and energy to carry out environmental Sound and optical transformation" will bring a better experience, but everyone's needs are different. I think there should be many people who do not have such a high demand as I do, and do not want to spend so much money, time and energy. Of course, this is not directly related to whether it can afford more money. Within the range of affordable prices, how much money you are willing to pay to achieve the level of demand you want to achieve is due to people. Different.

0.2 Formation experience

The author started building his own home theater from the New Year's Day in 2014, read many related articles, and also soaked up some related community forums. I found that most of the articles and the arguments of the enthusiasts are basically tens of thousands of minimum budgets, and the contents are too professional. There is an altar "AV199" to consult a whole family cinema with a budget of tens of thousands of yuan. There are very few veterans and patrons who will manage you because the price of one line may be four digits in the content of their discussion. This kind of altar wall will keep such people away from me. I also read a PDF e-book titled "Home Theater DIY Raiders." Among the suggestions given, the 5W block is just a starter version. What's being said is really professional. I can't read most of it. In fact, do not want to understand so much, I feel that spending so much money and energy to engage in these is not worthwhile; Moreover, the home has been renovated, the hardware conditions are not allowed, to do some renovations themselves too much trouble. The author has been suffering from the Internet's failure to find a valuable reference solution that suits himself. He can only slowly extract his own effective information from relevant articles and information, and he has finally established a set of his own. Satisfied home theater.

0.3 Share Experience Reason

The author actually thought for a long time, whether it is necessary to write and share this experience, because a lot of valuable professional knowledge is far more than me, the study is deeper than me, why should I come to work? When I opened the SMZDM experience submission page, I saw a sentence in the experience "Rules for submission", "If you can help a person, the text has value!" In the end, I decided to write something. I just wanted to make those people who are similar to me get a little experience, form a rough idea, spend less time, energy and money on this, and use the shortest and the shortest time. The time, the least effort, and the least money are needed to build a low-cost home theater that meets their requirements and enjoy the most fundamental and beautiful thing of watching movies.

1.1 Analysis

There are many specific definitions, and the definition of standards in each person's mind is not the same. Here I only give a simple definition of “applicable to this audience.” If you feel that you completely disagree with this definition, then this experience may not be Apply to you too.

Home theater is a set of video and audio playback systems that are built in ordinary family homes and in most cases will be superimposed on other functional areas of the home. The main hardware includes, but is not limited to, soft and hard conditions. Within the allowable range, a device that is as large as possible and the image parameters should not be too poorly displayed, a device capable of smoothly decoding at least a 1080P re-encoded video playback device, an audio decoding device capable of at least decoding DTS and Dolby Digital, and a set of multiple devices Channel speaker.

1.2 My Home Theater

Let’s take a quick photo of the author’s own home theater.

—————————— I am the dividing line ------------------

2.1 Analysis

First of all, you have to have a house (Oh), of course, apartment or rental house is also possible, as long as you think that the formation of a home theater will not affect others or the landlord will not interfere with you. Then select a room in your house that you feel is suitable to set up a home theater.

Most home theaters will choose to be set up in the living room because after all, the function of the living room is similar to that of a home theater, and the superposition will not be particularly abrupt. In addition, individual friends may also choose to study in the study room or bedroom. This is certainly OK. Your own movie theater is your own choice. All the discussion in this article will also be based on the establishment of a home theater in the living room. However, if you think that it is not strange to have a home theater in a toilet or kitchen, you can try it too. I think everyone is also very excited about the results.

2.2 My Home Theater

Like the whole house, my living room had nothing to do with decoration style. In addition to the newly renovated Chivas functional sofa in July, it was re-decorated under the sofa background wall. Shortage, all for the purpose of saving money, so it can only be "minimalist".

 

—————————— I am the dividing line ------------------

3.1 Analysis

In fact, there is no hard-and-fast rule on this issue. Some professional home theater instructional articles may give some basic conditions based on acoustics and optics. However, I think that for the audience of this article, they want to build a home theater. In combination, there is almost no room for choice. As long as it is based on the actual situation of your own consideration, you can finalize a room that you think is suitable. The author thinks that you can basically not consider those professional factors. The average family's living room, size and structure are fairly appropriate.

3.2 My Home Theater

My home living room TV background wall to the sofa wall is 6 meters wide and 4 meters wide. The restaurant on the north side and the study on the south side are not cut off. It is an open living room. This structure may not be strictly suitable for the seat home theater. Do I still have to choose?

 

—————————— I am the dividing line ------------------

4.1 Analysis

This issue can only be considered in accordance with its specific needs. If your room has been renovated and it is no longer possible to perform simple acoustic optical processing, then there is absolutely no need to consider this issue. If your room is not finished yet, simply embedding and reserving sockets, holes, etc., will make your room look more concise and reduce the difficulty of wiring when you build your home theater. Do something in the room walls. Simple sound-absorbing and sound-absorbing treatments, as well as decorating the ceiling and walls with dark colors, will give your home theater experience a boost. In fact, these are all on-demand and are not required, so this article will not discuss the decoration and acoustic optical processing. After all, most families are still unable to do this.

 

4.2 My Home Theater

Strictly speaking, I did not do any acoustic and optical processing. Well, if you want to see the projection during the day, then shading is also considered optical processing?

Although there is no window in the living room, I mentioned that my living room is open. There is a window on the north side attached to the kitchen to be shaded, and there is a large window on the south side to shading. As for the large bedroom and small bedroom, the door is closed. Can be shaded, the toilet does not have to consider.

 

As for the plan of shading, there is not much to think about. In line with the principle of “economical, as far as possible not to change the original state”, it is more appropriate to use shading blinds for shading. The original curtains in the kitchens and dens are rolled curtains. With this favorable condition, the blinds can be hung on the cross bar of the roller blind, and the installation and lifting operations are very convenient. So a good amount of window size in a purchase of two pieces of a suitable shade blindfold, and the attached hook according to the shutter curtain bar has been modified, hang, the effect is very good, break Feite ~ ~ ~

—————————— I am the dividing line ------------------

5.1 Analysis

At this stage, the main display devices for home theaters are flat-panel televisions and projections. It can be decided according to their own needs and actual conditions.

Comparing TV with projection, the advantage of TV is that the various parameters affecting the perception of the picture are better than the projection, such as brightness, contrast, saturation, color, etc. This is due to the fundamental difference between the display principle and technology of TV and projection. Caused. Also, when watching during the day, the TV does not need to be shaded, and if it is not light-blocked during the day, most people cannot accept that picture. The most fundamental advantage of projection is that the screen size can be very large (mainstream consumer TVs usually do not exceed 70 inches, and people who can buy TVs with 70-inch or more like Samsung's Sony LG do you think would be the audience for this article? ?), combined with the width of the general family living room, pitch, 100-133 inch impact of the screen is closer to the cinema, and, at night or daylight shade, the projection display effect will not be much worse than TV (part People who are not very sensitive to this may feel almost no difference.)

As far as the author is concerned, it is more prone to projection. After all, the projection is closer to the perception of the cinema. Therefore, this article will only discuss home theater with projection as a display device. As for the choice of 720P or 1080P projection, mainly to see the specific budget, usually less than 120 inches, 3 meters away from the line of sight, the election 720P is fully acceptable, the budget allows, choose 1080P of course, the screen will be more delicate.

Need to point out in particular that the size of the display device needs to be selected, this is still no hard rules and reference standards, this should be based on the individual's actual perception, combined with "in the living room space size limit" viewing distance (human eye to The distance of the display device) comes from the line size.

5.2 Equipment Selection Recommendations

Suggestion: Do not choose the no-name LED projection; try to choose the commonly used brand of traditional light bulbs for home projection products; try not to choose business education projection; try to choose a 16:9 ratio projection.

Do not rely on the LED projection of a variety of cottage brands on a certain treasure. The advertisements are blown to the ceiling. “Real shot” effects are quickly catching up with the big-name high-end flagships. But what about actual results? Everyone can go to some related forums to check out the real ones who have bought the lessons. These miscellaneous LED projections always boast the advantage of longevity compared to the traditional bulb light source (the general LED lifetime is 2-5W hours), but you can calculate for yourself, now the projector of traditional bulb light source can generally achieve With a lifespan of more than 5000 hours, even if you watch a 2-hour movie every day, you can watch it for nearly 7 years. Even if the factors that affect the effect of the light bulb's light decay are counted, it is at least 4 or 5 years old. The average family’s frequency of use is also less than two hours per day. Basically, it can guarantee that high-frequency use is already available for 6 to 8 hours a week. The replacement of light bulbs only takes a few hundred dollars. It takes several years to spend hundreds of dollars. The cost of replacing light bulbs is such that the cost is already very low (not to mention that some big brands have dual lights at the time of purchase) and there is no need to worry about lamp life and replacement costs. However, it does not mean that the projection of the LED light source itself is not good, but specifically refers to the quality of those cottage brands that are not qualified, various parameters are seriously false, and false propaganda.

LED projection is small in size, small in calorific value, and wide in color gamut. However, the brightness is much lower than that of a conventional bulb. Generally, it will not exceed 1000 lumens. It can only be clearly seen in the case of all-black lighting, and the bulb projection brightness Basically about 2000 lumens, some products have reached the brightness of 3,000 lumens, here is not recommended to use LED projection, is based on the family of common projection applications, there will be many times in the daytime, and shading conditions can not reach all black, so Compared with better colors, the first guarantee is that "can be seen" should be more in line with most home application scenarios. Normal curtains will be pulled in during the day, and bulb projections with relatively high brightness can still be used, but LEDs are basically not visible. Clear.

The above set of comparisons from the network, from left to right, are a 3000-brightness DLP bulb projector, a 1000-brightness LED projector, and a 1600-brightness 3LCD bulb projector, respectively, with the lights on and off. Real contrast, brightness level can be distinguished at a glance, and this is only a vote of 50 inches, the greater the screen projection, the screen brightness will be lower, if you cast 100 inches, the actual brightness of the LED screen shot everyone brains, Ha ha. As for the color, whether the effect of the LED's wide color gamut is oversaturated is a matter for everyone to judge.

Try not to choose commercial education projection because many features of commercial education projection do not meet the needs of home projection, and the details are not described here.

With respect to the projection ratio, it is actually quite understandable. Now the vast majority of movies are extra-wide ratios of 2.35:1. Choosing a 16:9 projection with black borders above and below, not to mention ratios of 16:10 and 4:3 The ultra-wide black edges on and off the screen are rather wasteful projection pixels and curtains. And most importantly, the size of a normal proportional movie screen that can be projected by a movie of the same size decreases as the aspect ratio of the screen decreases. In other words, the 100-inch 16:9 shot 2.35:1 movie, the actual display screen size is 94.7 inches; 100-inch 16:10 shot 2.35:1 movie, the actual display screen size is 92.16 inches; 100 inches 4 : 3 shots 2.35:1 movies, the actual display screen size is only 86.94 inches.

Recommended: Optoma, BenQ, Acer, these are the basic SMZDM often push the brand, home low-end models are more, low-end models will not be outrageous than the sea Amoy expensive, 720P licensed within 3000, 1080P licensed 5000-7000 yuan, this study is not a lot of home users or buy licensed more secure. Moreover, these brands have a relatively high market share. If there are problems that need to be communicated or there are common problems that need to be addressed, it is relatively easy to seek communication and help on the Internet. Saying that the recent listing price of the newly listed Optoma HD26 4999 refreshes the bottom line of 1080P projection listing price, a certain treasure looks like this price is also sent 3D glasses, but currently there is no sun list and reputation for reference, but based on In terms of brand and price, what kind of bicycles are needed for low-end homes?

Suggestions: Try to choose the curtains of common well-known brands; don't rely on the paradox of “the effect of cheap curtains below 2,000 yuan is not as white as the wall”; don’t worry about which kind of curtain material to choose; pay attention to the proportion of curtain width and height to match the projection ; It is convenient to choose the electric screen with remote control.

First of all, an objective fact is that there is specialization in the surgery industry and specialization in special applications. The meaning used here is to say that the existence of a white wall has not been specifically optimized for projection. Its essence is only a wall; and even the relatively inexpensive low-end curtains produced by regular manufacturers, their materials, processes and technologies , are also designed specifically for the projection, optimization and tuning, and its essence is dedicated to the projection of the "screen"! Well, usually the white wall and the curtain are effective, and the answer is obvious. This is a "common sense" that you can understand without knowing anything about the professional knowledge between the curtain and the projection. Regarding the material of the curtain cloth, we can learn relevant knowledge on the Internet and find out the differences and advantages and disadvantages between different materials. We must choose our own budget to choose. Now the technology of the projector is quite mature, and it is not necessary to reappear on the curtain. Performing a lot of compensation, even the most common white plastic curtain, will not be very bad.

Of course, the author does not deny that a good screen can improve the quality of the picture, but usually such a curtain is expensive. Based on the basic premise of this article, you understand. Moreover, one cannot ignore the fact that most people cannot detect the differences in the screens of different materials without seeing the “physical comparison reference” at the same time. (The projectors and amplifiers with the same price and the same orientation are the same The truth). This is not to teach everyone to learn from Ah Q's self-deception and spiritual victory, but based on the uniqueness of these devices at home and the less sensitive visual and auditory factors of ordinary users, to tell everyone that ordinary users do not play without fever is not the pursuit of extreme In fact, the need to decipher these subtle differences is quite low.

The main brands of the curtains are not many. The main choices of most ordinary users include Jingke, Hongye, Meishi, and Yinghui. Generally from 90-133 inches, about 500-1500 yuan can basically meet the requirements.

5.3 My Home Theater

My home TV is a LG 47-inch LCD TV that was purchased for more than 6,000 years in 2010. At that time, I thought that the 47-inch LCD TV is really not small. If you want to watch a TV program, if you want to use it as a home theater display device, consider the sofa to the TV. Nearly 6 meters, then 47-inch TV is really a small pitiful, this distance is not 100-inch no theater shocking feeling, TV is certainly not satisfied, after all, there are not more than 100-inch TV, more important It's price, you know, so what's up is that projection is the only choice.

In fact, in the first half of 2013, there was already an idea to buy a projector to set up a home theater. At that time, there was actually no relevant knowledge and no decision was made on when to buy it. Therefore, we only paid attention to the projection based on the price. At that time, only the Acer H6510BD was found to be the cheapest 1080P 3D projector, and there was no more to see. On the New Year's Day in 2014, the money on hand was relatively abundant, so we did not study anything again. We decided to start H6510BD in Jingdong, and the results were very satisfactory. .

On a few screen shots, Fuji S4500 telephoto DC + tripod shot, without any post-processing, the camera built-in battery is dead, no time to adjust the battery installed after boot, the default is 2012.1.1.

For the installation and alignment problems, the Acer projection calculator was used to calculate the corresponding projection distance. According to the lifting position of the curtain, it was determined that the projection could only be mounted in a place about 1 meter away from the sofa wall. The placement of wiring and other equipment, because my living room is very long, from the projection requires at least 10 meters of HDMI cable to walk to the TV cabinet (wireless program really expensive, did not consider it). I learned on the Internet that if the HDMI cable exceeds 10 meters, there may be many problems, then we must choose a very good quality brand HDMI cable, a few hundred dollars I feel too high.

Based on the consideration of saving money and not having problems, I decided to put players and amplifiers on the sofa wall, which greatly shortened the HDMI cable length. In the end, it took 81 to buy the 8-meter Green Alliance HDMI cable. On the power supply side, the upper half of the wall did not reserve sockets, so it took 53 more to purchase a 10-meter 31-square-metre projector power cord, and 200W of power. Such a wire should be sufficient. Based on aesthetic considerations, the use of bright trunking for wiring, selecting the corners and vertical alignment as much as possible, in fact, does not seem very dissonant at first glance.

Further reading: "Home Theater develop a plan chapter two: Install the parameters of calculation and DIY projector universal projector hanger ultra-stable" Author: last532,  

With regard to parameters such as projection pitch and corresponding dimensions, the projection of common brands and models on the Internet is based on a dedicated calculator or reference list.

If you choose to lift or hang the wall, it is best to calculate and measure in advance, and then carefully determine the location before construction. If there is a deviation in the location, adjustment will be more troublesome.

Determine the size of all the range, especially the projection distance, try to leave a margin, do not use the limit data to locate, for example, the 120-inch pitch range is 3.1m ~ 4 meters, then do not use 3.1 and 4 meters to determine Location, you need to take a certain margin, otherwise there may be unsuccessful or out of screen size.

Although the projector is basically universal, but before buying it is best to consult whether the customer service can be used on their own projector, just in case.

You can use the open channel to take the open line, try to choose the corner and vertical alignment, so that it will not affect the appearance of the ceiling and the wall cut, if the wall or ceiling is not white, you can change the outside of the open slot to close to the wall Or ceiling color.

As with the projections, the author did not actually study too much at that time, and purchased a red leaf's most common 120-inch electric white plastic curtain in Jingdong with the projection. The 120-inch option is a comprehensive consideration of the actual situation at home. First, the width of the living room is appropriate to the viewing distance of 120 to 150 inches. Second, there is no plaster screen decoration between the TV background wall and the ceiling. Can only be hoisted in front of the TV tens of centimeters. In this case, the speaker is too close to the middle of the screen will be blocked by the curtain, while the left side of the TV background wall is close to the entrance door, so it can not be too close, will block the entrance door. After calculation, the 120-inch is a more appropriate size, not too small, it will not block the speaker, there are enough space on both sides to let the sound pass through (the sound screen is really expensive, and 99% is the frame screen).

Electric curtains are very heavy, so when lifting or wall-mounting, try to load them directly from the expansion bolts into the floor and into the bolts deep enough into the wall!

Remote operation is really convenient, but if you feel that pressing the switch every time is not too much trouble, you can also connect with me to install the switch to a suitable position and height.

You can use the open channel to take the open line, try to choose the corner and vertical alignment, so that it will not affect the appearance of the ceiling and the wall cut, if the wall or ceiling is not white, you can change the outside of the open slot to close to the wall Or ceiling color.

If the screen exceeds 110 inches, it is necessary to pay attention to the problem of flatness, and it is easy to appear V-shaped lines. When viewing a movie, it is mainly reflected in some slow speed or moving the lens up and down, the screen will be bent and deformed in the V-shaped pattern. Although the impact is not great, but if you mind, try to choose the pull screen, you can remain flat, to a large extent to avoid the appearance of V-letters.

If you are really tangled in the choice of curtain material, it is obviously not realistic to buy finished curtains of various materials. Then you can find an online shop (or physical store) that has its own factory and various material screens. Talk to your boss and spend a small amount of money to make the owner take a small piece of each material, about 30 to 40 centimeters long and wide corners, scrap, send home to compare, see what is true, what kind of feeling It's better to decide which material to buy.

—————————— I am the dividing line ------------------

6.1 Analysis

Computers, high-definition players, Blu-ray DVDs, smart boxes, tablets, mobile phones, etc. are all possible. Of course, in line with the principle of “reduce purchase costs, reduce the use of costs, and simplify the operation process,” try to choose your existing, full-time equipment as a home theater playback device. "Existing" is of course for you to save money without having to purchase it separately; "professional" means that it is for exclusive use. It is necessary to avoid moving, wiring, and debugging every time you use it, and it is not necessary to perform related operations during playback. Need to get up and walk around. Believe me, these things that need to be repeated each time you watch (high cost of use, complicated operation process) will give you a terrible experience in enjoying home theater. It won't take long before you may be in trouble. Fewer and fewer frequencies go to home theaters and even idle at the end. As for playback capabilities of playback devices, 4K has now started to be hyped. Basically, any playback device out of these two years should be able to decode high bit rate 1080P without any pressure. Basically, there is no need to worry about it.

6.2 Equipment Selection Recommendations

The choice of playback device needs to fully consider the functions (only considering video playback), performance (consider only video playback), volume, power consumption, noise, ease of use (interface and operation), interface compatibility, and the like.

Based on these considerations, the common advantages of the desktop host, HTPC, notebook, mini-host, high-definition player, and network TV box are usually selected as follows:

Desktop host: large space, a variety of cooling fan noise, high power consumption, full-featured, good performance, ease of use in general;

HTPC: The situation is close to the desktop host, but the volume, noise, and power consumption are relatively small;

Notebook: small size, low noise, low power consumption, full-featured, good performance, ease of use;

Mini Host (By System): Relatively small size and low noise compared to laptops. Part of a fanless product using a solid-state drive can be basically noise-free, low power consumption, full-featured, high-performance, and easy-to-use. ;

HD player: small size, basically no noise, low power consumption, general function, good performance, easy to use;

Network TV box: small size, no noise, low power consumption, general function, general performance, easy to use.

If we consider the cost factor comprehensively, the 200-500 yuan network TV box and HD player are the ideal choices for the audience. If the balance is considered, it is recommended that this friend who has more budget should consider the mid-low allocation mini-host (about 1,000 yuan). Barebone), the reason why self-organizing HTPC is not recommended is because individuals feel that based on the target group pointed out in this article, the self-organizing HTPC requires certain related knowledge, and the power consumption and noise of the HTPC itself are still high, and the performance is also for playing videos. Excess. There is no mention of Blu-ray DVD here. In fact, the reason is obvious. The low-end features are relatively simple and the high-end prices are not cheap.

6.3 My Home Theater

In fact, the purchase of this mini-host is not for home theater, mainly because the original desktop host is too noisy and too power-consuming. I only go online, do not play games, and do not need high configuration, so I would like to change one configuration enough , no noise, low power consumption of computers to the Internet, only purchased this mini-host. After accidentally discovering XBMC's excellent media center software, he decided to use this mini-host as a home theater player. This mini-host, compact body, placed on the computer next to the study room next to the living room, does not account for desktop space, HDMI received a living room projection, VGA access monitor usually online office. Adjusting the display mode to an extended display allows the same host to view the projection of his wife at the same time. I use the monitor to access the Internet. There is no delay. Performance, IVB architecture of dual-core Celeron 1037U with HD2500 nuclear display, regardless of the hard and soft solution 1080P or Blu-ray original are without any pressure, while the power consumption is usually not more than 20W, and is based on the passive cooling aluminum body No fan or no noise, no matter if you are watching a movie or using a computer, it is much quieter than the usual desktop host and HTPC that the fan is mad. After you use this, you really don't know how to endure the noise of the desktop host. In the later period, the host was equipped with a 2.4G multimedia remote control. In conjunction with XBMC Media Center, it completely solved the problem of inconvenient accessibility of the mouse and keyboard, which was basically equivalent to the ease of use of high-definition players and network TV boxes. Poster style interface is more beautiful and intuitive.

Several small experiences

Use a computer as a player. Since the computer's operating system is optimized for desktop operations and is not suitable for living environments such as living room TVs and projection theaters, the use of computer-side media center software and remote control can be used to the maximum extent possible. Improve ease of use.

Using a computer as a player, reducing size, power consumption, and noise are critical.

Purchased in the double 11 in 2012, was mainly to watch TV variety shows online (at the time there are not so many Android web players), or to see local movies. RTD1186 program HD player video playback capability is still very good, decoding high bit rate HD encoding 1080P even the original Blu-ray disc is very smooth, and supports Blu-ray 3D output, as a local high-definition video player is also quite an ideal choice . Compared with computer playback, the picture quality is more transparent and natural, and the perception is slightly better, but the gap is not large. However, in terms of playing related functions and settings, it is still less than computer-rich, but it can already meet the needs of the vast majority of people. Since this high-definition player is not the main player for online video playback, the built-in non-intelligent online video platform is often effective, so in 2013 the dual 12 purchased Lynx box to watch TV online video, he also relegated to the second line on the projection Play here for the rest.

Little experience

1) The performance of the Android Internet TV box has been increasing rapidly in the past two years. Decoding high-definition video is no longer stressful. Therefore, it is still more economical and practical for home users to choose various Android boxes as home theater players. The show is also very convenient.

7.1 Analysis

声音这件事，个人的需求高低千差万别，谁也无法给出一个适合每个人的建议，只能暂且根据笔者自己的一个综合考量，给出一个最低要求，即最好能保证音频系统是支持DTS和杜比数码解码的5.1声道功放、无源5.0音箱和有源低音炮这样一个组合，这是最基本能保证“影院”这个概念的一个音频系统。能够称作“影院”，笔者个人认为最起码应该提供“环绕多声道+重低音”的一种音效体验，也主要为了区别于“普通电视或者桌面电脑多媒体音频”的“双声道且没有低频或者低频浑浊”的一个声音系统的听感，提升观影的体验，毕竟一个“最最基本的家庭影院系统的体验”也理应是要高于“用普通电视或者桌面电脑、笔记本等等设备去观影的体验”。至于部分人有意上升到次世代音频解码或7.1以上声道系统，甚至分开前、后级功放以及用更高级的线材，基于本篇经验是“低预算”和“观影为主器材为辅”的原则，这些就不在本文的讨论范围了。

还要单独强调一点，千万不要认为，如果家庭影院的主音箱是全频带低音单元的，就可低省略低音炮。在高清影片的多声道音频中，是有一路单独的音频信号负责重低音的传输。也就是说影片制作的时候就已经单独把需要加强低音效果的场景的低频和超低频单独交给重低音声道，并传输给只负责低音的低音炮音箱来完成低音的输出。所以如果你没有低音炮，只有5.0音箱，那么你将会失去影片部分场景的低音声道的音频。即便是你通过功放将低音声道混音到主箱中输出，那低音的效果也将大打折扣。通俗点讲，因为主箱的喇叭单元的尺寸以及声学结构并不是专门为加强低音设计的，低音的下潜以及量感，始终是不及专门为低音而生的低音炮，这与前面章节5.2.2介绍幕布与白墙的区别时，所遵循的基本原则是一样的，“术业有专攻，专用需专物”。

7.2设备选择的建议

在这里有必要单独说明一个问题，笔者并不建议大家选购三星、LG、索尼等品牌的DVD（或蓝光DVD）搭配“音柱”式音箱的“家庭影院套装”，哪怕这些产品会有部分型号是无线的环绕音箱，可以解决无预埋音箱线的问题。原因主要有三个：

1）DVD（或蓝光DVD）这样的播放器，碟片是需要再次投资的，哪怕可以播放下载的视频文件，其相应的视频文件兼容性以及功能和设置都相对简单，后期遇到一些播放问题的可能性比较大，最后有可能因此就闲置不用了。

2）这种套装的播放主机基本都集成了功放的功能，即便是你不用它来播放，只用它当功放，自己另接播放器，还要注意匹配接口，由于这样的主机本身就是播放器，所以基本全部都不会有HDMI输入，只有部分型号会有光纤音频输入，如果不了解清楚，是很容易买错的。

3）这些品牌虽然响亮，但都不是专门做家庭影院音频的，这种千元多的套装的音柱式音箱的素质真的非常一般，这样的产品主打的就是外观，看起来可能会比较时尚，但是买这种套装，最后真的可能沦为“家具”，只是个摆设。

低端入门的AV功放，日系功放是比较合适的选择。其实低端入门AV功放各个品牌之间不会有太大差距，一般只有风格和各家独有的音频处理技术的差异，而同品牌内同级别价格相差不大的型号之间区别更小。非“玩家”只是普通家用的话，大可不必为选择什么品牌和型号而纠结，这些品牌哪怕是低端入门级也都是可以满足家用需求的，只需要注意一下与音箱的阻抗和功率的匹配，阻抗一般为6~8欧姆，功率50~100W就可以满足10~25平空间的一般需求。尽量选一些销量比较高的型号，无论是使用交流和问题处理上都相对容易一些。

选择功放的时候还需要注意一下接口。首选带有HDMI接口多进多出（一般低端入门都是3、4进1出）接口的功放，HDMI可以同时传输音频和视频，而且多数音视频设备都带有HDMI接口，可以简化线材的连接；光纤和同轴输入其实现在也很少用到，并不是必须的，但是一般功放还保留这两种数字传输方式；现在模拟输入基本已经用不到了，所以完全可以没有多声道模拟输入；另外视频端子的输入输出，现在很多新上市的入门功放也都取消了，很少用到。

对于近两年新上市的功放新加入的功能，一定要按需选择。比如网络功能、无线DLNA、AirPlay等等。其实这些功能相对于功放的本职工作来说，都是附加功能，不要以这些附加功能来作为选择一款功放的决定性因素。当然，如果你选择的功放刚好带有这些附加功能，并且与其他不带这些功能的候选机型的主要功能差异和差价并不大，也是很值的。

推荐：先锋、雅马哈、天龙、安桥、马兰士等这些品牌的低端入门型号的功放，或者其中个别品牌的一些入门级“5.1或5.0音箱加功放”的“家庭影院套装”，都是比较合适的选择，值友可以搜索翻阅一下SMZDM以往的优惠信息，低端入门全新2000元左右就可以买到，并且完全够用。

常用家庭影院音箱分为卫星箱和落地箱两种。如果客厅面积只有十几平，视听距离4米以内，选择家庭影院卫星箱套装比较合适，小巧不占空间，家庭影院卫星箱的单元大小和功率也是完全可以满足小客厅内所需观影的声压级的。如果客厅面积有二十平以上，视听距离大于4米，有富余空间摆放音箱，那么建议买喇叭单元尺寸和功率都相对较大的落地箱，客厅空间大、视距长的话，卫星箱的能力就显得捉襟见肘了。当然这只是基于对音箱的一般理解的建议，如果你懂得音箱的信噪比、谐波失真、灵敏度、频响范围这些参数的具体含义，那么就应该知道，前面这条建议对于卫星箱和落地箱的实际表现并不是绝对的。但对于本文的受众来说，真心没必要懂这么多，自己实在不会选择，可以求助老鸟直接推荐一些型号。

音箱选择也要考虑摆放与安装方式，根据客厅空间和电视柜实际可用的空间来选择尺寸合适的卫星箱或者落地箱。如果你已经或者打算在墙壁预埋音箱线，那么就可以选择可挂壁的卫星箱，这样看起来会比较简洁。如果你没有预埋音箱线，而电视柜这边又没有空间来摆放音箱，那可以选择落地箱或者购买音箱支架，也是非常美观实用的。

推荐：先锋、雅马哈、天龙、JBL、尊宝、安桥等这些品牌的低端入门型号的5.0或5.1套装音箱，或者其中个别品牌的一些入门级5.1或5.0音箱加功放的家庭影院套装，都是比较合适的选择，值友可以搜索翻阅一下优惠信息，1000-3000元，浮动比较大，大家按预算和需求合理选择就好。

十几平的小客厅，可以选择6.5或8寸的低音炮，额定功率50W动态功率100W左右就足够使用，二十平以上或者低音炮摆放的位置距听者较远的话，可以选择8或10寸的低音炮，额定功率100W左右。对于本经验的目标群体来说，这种参数级别的低音炮就可以满足需求。原因有两个，第一是多数家庭的环境上12寸及以上大尺寸及额定200W以上大功率低音炮，是性能过剩的，因为本文所述的基本前提就是普通家庭叠加其他功能区域的家庭影院，没有单独影音室，也没有去做专业的隔音吸音等声学处理，大尺寸大功率的低音炮开很小的音量就可以让这种环境下的听者达到一个低音加强的感受，多出来的性能是得不到发挥的，这种使用环境下，即便是有需求把低音开到很大声，达到裤管生风的震撼，你上下楼和左右邻居有可能也会被震撼到，以至于来敲你家门感谢你……而另一个很根本的原因就在于，大尺寸大功率的低音炮会大幅的提高你的预算，这并不符合本经验的基本前提。

推荐：雅马哈、先锋、安桥、尊宝等等5.1音箱套装内自带的低音炮一般都能满足需求，单独的有源低音炮，价格比较低的大牌真心不多，除了雅马哈的几个型号在2000以下之外，再低就是几百元的一众国产品牌了，这个真心见仁见智，我个人倒是觉得可以接受，但是一众烧友和玩家恐怕就要跳出来开喷了，或者他们觉得根本就不值得喷，呵呵。

7.3我的家庭影院

说起功放、音箱和低音炮，笔者自己也是经历过一次升级的，在现在正使用这套设备之前，是一套国产品牌的功放和5.1音箱套装，是今年初跟投影和幕布同时购买的，当时对音箱功放的认知几乎为零，大概搜索了一下大牌的功放音响，都超出我的预算一大截，也没想太多，选了一套相对便宜一些的国产就立刻拍下购买了。使用半年之后，6月份升级到目前这样的组合。

之前那台国产功放，是最基本的DTS和杜比数字解码的5.1声道功放，HDMI1.4的4进1出，带蓝牙，功能虽然不多，但是也算够用。由于跟音箱是一整套，想升级音箱单卖旧的这套音箱的话，肯定是不太好出，所以就需要连功放一起整套卖掉。准备更换功放，但是大品牌入门全新的都要接近2000元，真心不想花这么多的钱，于是开始关注二手市场，我的基本需求就是带HDMI多进单出和次世代音频解码。没多久，在Q群一位好基友“一色风纱”（在此表示感谢）的推荐下，我看到了这台110V电压版的天龙1610 5.1声道功放，虽然型号比较旧，但功能上满足我的需求，关键是价格相当划算，只要700元还带1KW的220V转110V的变压器、奥德赛声场矫正咪头和后配的遥控器，于是最终花了728元购入，卖家只收了28元邮费还自掏腰包补足了几十元的德邦物流以及送货到楼下的运费，很实在的一个人。

目前功放使用情况良好，功能相对原来的国产功放的确多了很多强大很多。带有两声道PRE OUT前级输出，可将5.1声道扩展为7.1声道，只需要将信号通过PRE OUT输出到后级功放接无源音箱，或直接输出到两个有源音箱，笔者现在也正寻找合适的二手音箱，预计再花费200以内就可以升级到7.1声道。

如果预算不足，考虑二手设备也是个不错的选择，前提是你以前买过二手商品并可以接受二手货，这将会让你以同样的预算支出得到更好的效果或是达到同样效果的基础上缩减开支。

有时候声音或者声场有些怪怪的或者不是你想象的效果，可能并不是功放本身不好或音箱不好，很有可能只是功放的设置问题，很有必要去学会使用功放。

关于功放的使用，想要发挥功放应有的能力，需要反复仔细的研究说明书，并实机操作对照，研究明白之后，按照影院房间的实际情况和自己的主观听感来调整到一个最佳设置。如果随功放没有附带详细的使用说明书，可以在网上搜索一下。
