Look cool European Cup to avoid detours, clearly understand the white door - novice home theater dry goods to share

This article is divided into three parts.

The first part: nonsense articles

No way, it is more nonsense, do not like to listen to nonsense please skip.

Part II: Purchase Experience and Installation Experience

Although I thought about it thousands of times in my heart, it was the first time I really started to implement it. Good or bad, for reference.

The third part: related concepts and points

This is some of the theater knowledge that I have accumulated over the past few years. It is not responsible for right or wrong. .

The first part: nonsense articles

    All of this content has nothing to do with the theme, but there is no way to say it can not help but ah.

It has been a while since I met Zhang Aunt. She hasn’t done much (because she has no money), but she has learned a lot. He has always coveted Aunt’s public welfare measures and wrote several original articles. In order to defraud me of gold coins, I left an open box for almost every item I bought, but I didn't send a few copies at the end. As a result of late stage lazy cancer, the second to come to understand slowly, there are gold coins and the lack of weight of originality, but also can not win the public policy qualifications.

What I want to say is that this is not to swindle gold coins. The bottleneck of public opinion is no longer a gold coin. . . . I came to cheat projection! ! Um, yes, my movie is now a short projection. . . Of course, I know that the projection is more difficult than the public test. Actually, I wrote this as a challenge. As a procrastinator with severe symptoms, I have seen so many photos that have not been sent out of the box. The decoration is over and the decoration stickers I want to write are not written. This time the essay was essayed by the grandmother. I have to submit an article no matter how busy I am! I will not tell you that my cinema is not yet completed.

Prove yourself, start with an original! !

The second part: purchasing experience and debugging experience

Want a set of audio, there is no unplugged grass from the university computer. At that time, I liked sound, but I was still confused about the concept of multimedia speakers, active and passive workshops, and just a few years ago, multimedia speakers were also hype for independent power amplifiers. I always felt that Edifier 5.1 was already very high-end. The configuration. The computer still retains some reference materials collected by the students. All are now in the cloud notes. I am a person who is sensible and disrespectful. I am not willing to throw it. I am not willing to delete it. . . .

Gradually he graduated from school seven or eight years, because the house did not land, the cinema's affairs can only be in my heart. But from time to time, it is still concerned about the forum. When I was about to build a speaker this year, I deliberately went to the forum and asked a question. I was surprised to find that I had asked questions in the forum several years ago. At that time, I still didn't understand the difference between hifi and av. In this way, my theoretical knowledge has improved over the past few years, although progress has been somewhat slow.

In the past few years, she has been living in a simple rental house with her girlfriend. There is no TV. Everyday, she watches a movie on Youku with her girlfriend against a 24-inch monitor. Simple, but also very satisfying. But finally still a year ago, did not hold back, entered a polar meter z4x in Jingdong. I have also been concerned about the debate on micro-investment. The last thing that prompted me to make up my mind was to look at the trial of micro-investment in the Big V Spring Roll. He thinks that micro-casting can basically serve as a minimalist mini-cinema system. I believe him, although there will inevitably be some advertising ingredients, but I think it will not be too far off.

After an inspection, I chose one of the nuts and rice, and finally chose the z4x, but also because of the shape of its record player, I bought a single for my feelings. At the time, it coincided with the Jingdong Polar Rice discount, and 2499 also presented two 3D glasses. Now that one year has passed, there is no longer a time when it is cheaper to see. At the time of buying this machine, it was also an intention to hold the transition to a rental house. I did not expect this machine to give me amazing feeling after coming. It may also be why I have not used any high-end machines. Although there wasn't even a full-fledged white wall to show it in my humble rental house, I found a few positions with a few nails and a wire. But its convenience, sound effects and picture quality really made my happiness a lot bigger.

Regarding the opening of Z4x, there is already a lot of Aunt Zhang. I will not toss. Taking into account the tight budget of the decoration phase, projection will not be replaced for the time being. My principle is to solve the problem of being good and bad and solve the good and bad problems first. Self-righteous, it is considered pragmatic.

Finally put the purchase of speakers to the agenda, wallet restrictions, my eyes have been fixed on the recommended set of Aunt Zhang. Onkyo Tianlong Yamaha, Harman Jbl Boston. . . . Theoretical knowledge knows but does not personally experience it, so the criteria for selection are only price and shape, and brand preferences.

I had no choice but to choose to go to the forum for help. The login account suddenly saw the issue I had consulted with cinemas a few years ago. The tangled issues were almost the same as they are now. I liked the same things. . Please don't laugh. . . Yes, I always liked Marantz just because of her name.

Above is an excerpt from my post in the forum. After learning at the forum, I appropriately raised my budget and first eliminated the satellites. In consideration of the fact that I also sent a lot of netizens recommended to go underground. According to my specific situation and budget, I have also discharged a lot of floor boxes recommended by fans. Kef is a brand I have been watching for years, and my family's coaxial technology is just a few technical terms that I have known so far. The preconceived reason causes me to pay close attention to the speaker of kef, and kef is also recommended by many predecessors, can be matched with Marantz, taking into account the choice of music. The kef q300 suit became my first choice.

At the same time, another strange brand appeared in front of me - Danish Dani. Dani and Kef are also recommended by many people for matching with Marantz. The same grade box is half inch larger than the kef size, and the price is a few hundred lower. Dani and Kef are everywhere on the web. So Danyindian 3 set has also become my choice.

In fact, in my goal, there is also the same brand from the United Kingdom and kef beauties, and Dani also from Denmark's Jambo. The reason is that the price is reasonable and beautiful. However, I heard a lot of arguments that these two brands are not in the past and they tend to be furniture. He gave up. In addition, I simply learned a few American and German brands. I think that it is generally considered that theaters are partial and listening to music is not very appropriate.

In order to reduce the burden of purchase, I locked the target in kef and Dani. At this time, my budget has risen from 5,000 to 10,000. . . The goal is set, immediately start asking and audition everywhere. Seriously, I never did anything so resolutely. I listened to a lot of places many times during the two days of concentration, and took my wife who had no interest in it and had no interest in the sound quality. After an accidental audition for Bao Sina, the wife quietly told me that I was allowed to raise my budget to 20,000.

In retrospect, the novice ear of fungus did not hear the difference between Kef's British sound and Danish sounds. Did not appreciate the positioning advantages of the kef killer coax unit, nor did he appreciate the bass advantage of reaching the 7-inch unit. The selected tangle point then returned to appearance and function.

Kef q series, stylish and modern (decrease points), coaxial unit forcing high (plus points), front guide hole, can be closer to the wall (plus points), dual audio interface, to facilitate late power amplifier (plus points) The specific volume of the box without the high-frequency unit is larger, especially the q100 is much larger than the Department 1 (decrease points), and the price is slightly higher (less points).

Dani Collection series, the traditional appearance of simple (plus points), large size bass unit (plus points), rear guide hole (minus points), single audio interface (minus points), small size (plus points), cheap ( Add points)

Considered comprehensively, Dani wins, especially in the stretched space, the volume becomes particularly important. (The price is still cheaper.) In fact, Dani also has a reason to attract me, is a higher level of Dani ikon 2 compared to kef with the same level of r300, whether it is sound quality, shape or price are more attractive to me.

Dani this ikon2 let me shake for a long time, almost used it to replace the Department as the main box 3, shape, quality, size, it is a comprehensive upgrade. The kind of ascension is the feeling that I feel as a fungus. The price of ikon2 is about 3,000 higher than that of Concordia 3 and is acceptable. Hesitated again and again, I still chose to give up. Because at the time of audition, people are home to the top hifi amplifier plus professional listening room. Move back to my home, entry av amplifier plus open space, it is estimated that I will instantly return to the ranks of fungus. . . . To make a hifi amplifier for this box, the budget changes suddenly become big.

However, the difference of 3,000 yuan has not been saved. I added a subwoofer. I had never considered the subwoofer and I was afraid to disturb the people. Many people gave me Amway I have not been brainwashed. I figured out after the group. . . The process of ideological struggle is as follows.

Almost forgot to say power amplifier. Has been concerned about the Marantz nr series, because of the small, anyway, I have always been a low demand for the film. But was later upgraded to Marantz sr5010 by Amway. In addition to the difference in power, the main difference is that the 5010 supports the pre-stage output, and if the power is insufficient afterwards, a post-power amplifier can be added. That's right, adding a post-class is already in my plan. Just do not know when the plan can be achieved.

To say a few words, for the theater to listen to a ring, I am a little demanding music, the original plan is to reel the satellite package + entry bookshelf. I always thought this was a perfect way to get started. However, as my learning progressed, this idea was gradually overturned.

First, the power amplifier in the Cosmo satellite package cannot handle the bookshelf well.

Second, listening to music is the most important for the front-end home box, but watching the movie is the most important for the center, the vocal dialogue is in the center, and the front only plays the main background sound. If the front is much stronger than the middle, watching the movie must be strange.

Third, the first three bookshelfs are all around, but the prices are not high. . . . Not as good as a full set of shelves. .

Is it familiar? Want to buy Giant, accidentally got a Jetta. That's what I said.

Inquiry bargaining process is not a table, anyway, I think the price is not high, Shenyang City store prices are ridiculously high, they are more than once on time, I have online prices are problematic products. But I still chose a big shop online. Gamble! In addition, I need to say that Dani, Kef and Marantz are very strict control channel prices, so do not just look at the Taobao price, please ask customer service, there is a surprise.

Speaker amplifiers are large, take the logistics, postage more than 300. One by one I myself was on the fifth floor. Although tired, but my heart is not cool.

Since the election began in September last year, an important choice is whether there is a location for a cinema. For this reason, they also gave up a few options that are not available for low-cost flats. Of course, there is still no money. Because of the constraints of many objective conditions, my wife and I chose an old house with an area of ​​only 45 meters and a room age older than me. The old houses are large bedroom small living rooms. This so-called two-bedroom house has only one restaurant instead of the living room. After several considerations, I removed one of the bedroom walls as my multifunctional room. My daughter-in-law said that it was my toy room.

When installing hydropower, I got rid of the decoration company and buried the audio cable in the wall. The opening area is only poor 3.52.7. The distance between the sofa wall and the TV wall is only 2.7 meters. The sofa bed is also very cramped. So in the initial planning, I did not consider the TV cabinet. The power amplifiers and the electronic devices that may be used in the future are all planned to be custom-made in the closet next to the sofa. The advantage of placing the amplifier on the side of the sofa wall is that the power amplifier is close to the projection distance, avoiding long-distance HDMI signal attenuation and high prices. The wiring complexity on one side of the amplifier must catch up with the weak box. The fault on the side of the sofa wall is obviously not clear. There are sofas in the front.

The results became a success, and now there is a mess in the back of the sofa.

Because I'm not sure when I can buy the speakers and I don't plan to buy a TV cabinet, I installed five audio jacks in advance. As a result, the plan has not changed fast. I not only got the TV cabinet, but also got a full set of equipment early. Regarding the connection of the device, it is simply not worth mentioning. Because the power amplifier has a detailed installation and commissioning instructions as soon as it is turned on, it is simple and irritating. In fact, when I installed it, I also spent a lot of effort. I didn't get a step to ask for customer service. Later I discovered that, in fact, I just need to boot. . I hope other friends do not go the same way. Detailed content, Aunt Zhang has a lot of great gods have detailed instructions. For example, the following one.

Here is a mistake, do not remember where to look at the Raiders, the latter around the back of the sofa to be about 1.8m high, spacing the width of the sofa 60cm or so. Maybe I missed the key content, and I found that this position is not at all reliable. The box is not big, but it is still a lot bigger than the satellite box, so it is not easy to adjust the angle. Because the voice is moving forward, it cannot go straight to the ear. I'm looking for a load-bearing, box-supported wall-mounted bracket that supports long-arm steering. Did not encounter the right, so the cost of nine tigers and two tigers, the newly broken furniture drilled a lot of holes. . . So that's it. One on the bookshelf and one on the shoe. Both sides are not as high. But I think this is cool. What do you think?

The setting and debugging of the subwoofer is a difficult point in the configuration system. I didn't understand it too much. Fortunately, Aunt Zhang has a big god, such as the following one.

Originally my artillery was placed on the side of the main box, but afterwards I placed the subwoofer underneath the center for aesthetic and space considerations. The TV cabinet underneath my home was placed in the closet next to the sofa.

Projection wall to the sofa wall, remove the size of the projection itself, also about 2.5 meters. With a transmission ratio of 1.2 meters, the entry-level products of major brands are also 1.2 transmissions. The projection size of one hundred inches is 2.7 meters, and 2.5 meters can be about 90 inches. It is enough in this room (of course, again I can also accept the bigger one.) Of course, in order to get the largest possible screen, I gave up the projection screen. One is that the projection screen will occupy a little projection distance. The other, I think a low-end projection screen is not necessarily better than the white wall. The good projection screen has a bit to match with my 720p projection cloth. When do you change the projection and consider the projection screen?

I made a mistake here. I thought I was burying a thick tube behind the sofa. It was too rough to allow me to wait until the decoration was finished before I could thread it in. I changed the thread and placed a power supply in the upper end. Network Interface. The problem is that, I see people's projections are hanging in the ceiling, my house is still a short frame, I change as much as possible to keep the top of the tube on the upper. As a result, my lovely micro-cast is really a toy. Its trapezoidal correction is electronic rather than optical. After the correction, it will leave a very obvious trace of trapezoidal light leakage, and 720p will not have high resolution loss. In a word, it cannot be used. So I cleverly drilled a hole in the middle of the wall and installed two partitions on the wall. The power comes in through the top hole, and the amplifier is connected through the second hole. HDMI goes down the middle of the hole and comes out in the hole below to connect the amplifier.

I am lazy and do not have the mind to calculate the level of right and left. This is good. I can move around, but I can't get enough height to padded it. You may not feel beautiful, but I think it's okay. Cool? I like it very much. I still get it by changing the house.

Said that this toy projection is not good, let's talk about it is good, because the built-in Android, can independently decode multi-channel, I also made a coaxial line for it with HDMI out from the tube connected to the amplifier. Now I do not need to open the computer to handle most of the video playback, and can support multi-channel output. Because of the manual line, I had no experience. At the beginning, I made a conventional coaxial line. Later, I found that the coaxial port of the pole meter was not a universal interface. Instead, it was the same as the millet box. Instead, the 3.5mm connector was used instead of the coaxial one. Lotus head.

In order to make this solid manual coaxial line not to be idle, I have ordered a patch cord. Inside the tube is linked to the amp with HDMI.

By the way, this micro-projection has a two-force design, and the built-in hard disk compartment can hold a 2.5-inch hard disk, but because the built-in speakers are too strong, the hard disk will be damaged. . . Therefore, the official statement stated that it is recommended to put SSDs. Of course, this problem is no longer a problem after my coaxial output.

In any case, in effect, this projection is a shortcoming of the entire system. If there is a budget upgrade system, projection is the first priority. So, I want this projection. . . .

Amplifier speakers are all available, and my current broadcast equipment is now mainly computers and micrometers. My original plan was to bring the computer hdmi to the amplifier, and the amplifier would have two HDMIs, one to the projector and one to the computer monitor. I thought I could do the expansion mode like an external computer monitor. However, the two outputs of the amplifier output can only be the same content. No way, connected for a long time, finally connected the computer and monitor with DP line, and set the computer's audio output to HDMI to Marantz. In this state, I am very comfortable.

Attach a so-called topology map. . . What ppt does is a bit simple.

There is also a basic quote. Since the speaker is a suit, the price is slightly lower, and it should not be possible to purchase it alone. .

The third part: related concepts and points

What I need to declare is that I have a lot of information learning before I buy my own audio system, but it is only theoretical knowledge. In fact, there are many professional and systematic posts available for learning at the Forum and Aunt Zhang. These are far more detailed and professional than what I have to write. However, I still try to sort out the basic content that I understand and try to express simple knowledge in a simpler way. It is hoped that some value-friends can be solved to reduce the time cost of their access to information and choice of products. Most of the following content is what I have learned on the Internet. I try to falsify the truth, but it is inevitable that there will be something wrong. If there is any mistake, please correct me. I think the above content should be attributed to "nonsense" articles. . .

Closer to home.

Home theater is God horse?

As the name implies, home theater is the effect of creating a movie theater at home. In my opinion, as long as there is a screen with a speaker, you can complete the movie and you can count the theater. Think of the open-air movies that we climbed in the trees for the past year. Think about the American drama we were happily chasing behind the 14-inch notebook screen in the dormitory. All that can make you feel happy is your movie theater. For the common arguments on the forum: “Twenty thousand or less to listen to a ring” and “The following ten thousand yuan is rubbish”, I am very dismissive.

Of course, the so-called home theaters that people are discussing often have certain requirements for influence and sound. For viewings, there is at least a large-screen TV, sound, at least 5.0 surround sound.

Since it is a system, it is naturally more complicated. I can only briefly summarize it.

Video playback system - amplifier - audio and video playback

Of course, for many old fans, the dial and the interface are separate, and the decoding and power amplification are also separate. The sofa and even the decoration are all part of the theater, but these are the old things. As a newcomer, we still start with simple things.

Storage device

With the development of science and technology, along with the diversification of playback devices, the storage of video and audio has also undergone corresponding changes.

CD: After the tape gradually withdrew from the historical stage, it has always been the main channel for the distribution of genuine audio and video. The advantages are easy access and convenient playback. However, the relative inconvenience of collecting, the acquisition price is also high. The convenience of the Internet and the lack of a domestic copyright system have caused most Chinese people to buy pirated discs too expensive. Of course, there are also many people who buy used discs and can sell them after watching them. So for those who like to watch discs and are not afraid to toss, you can choose film. Good conditions, like the collection, you can consider buying a new disc.

Hard disk: There is no doubt that the hard disk is the most cost-effective choice today. Even if there are dozens of original files and hundreds of G, the storage cost of hard disks is still low. For those who like to download their own files, those who like to collect files, those who read the files that they want to delete, in addition to the hard disk, they can not find any other way. For many junior customers who use pc to play video on a part-time basis, the computer's internal hard disk is often the way to store files. For users who burn a little bit, an external hard drive will be indispensable. From a 2.5-inch mobile hard disk to a 3.5-inch external hard disk that needs to be connected to a power supply, there are many more external hard disks that are directly on the hard disk box or array box. . . .

Nas: Also called network storage. This concept has already appeared very early, but it is still a few years since it started to spread. (The so-called popularity is actually paid attention to a very small number of people.) NAS can also be understood as an external hard drive in essence, but he is far more than just a hard drive that can be stored. The self-contained NAS has increasingly taken on the tasks that a computer can perform, and even supports the playback of video and audio data.

In view of the current situation, NAS is still extremely lack of cost-effective products, relative to its configuration and performance, the price is a bit high and outrageous. So your DIY nas is also a good choice. "Black dress" is a good choice for self-assembly nas, of course, you can choose free nas and other open source systems. The function is similar, the price is cheaper, the price is time-consuming and laborious, and may be lacking in power consumption, noise, stability, appearance and so on. Each has its own advantages and disadvantages.

Playback device

Science and technology facilitated living, when the emergence of multimedia applications made the personal computer the ultimate terminal for personal entertainment. Now, any gadget can decode high-definition video, which also gives home theater players more options.

Disc player: A name that has been categorized as a player for years. Regardless of the effect, the actions and sounds of opening the discs to change discs have become a kind of feelings. Corresponding to the above storage device, if you have a large number of discs, or you want to have a large number of discs, the disc player is naturally a chop that you can't bypass. The advantages of the disc player are easy to play and the picture quality is good, and now the disc player usually has a good digital player function. To say the shortcomings. . . Do not know if the volume is big. . . The main thing is that, for those who do not have disk stock, it is of no use. The Pioneer Pioneer product is excellent (for jailbreaks), and customers with ample budgets are more likely to opt for oppo products.

Hard disk player: Disk player, hard disk player is naturally in order to play the contents of the hard disk. The advantage of the hard disk player to the disk drive is like the advantage of the hard disk relative to the optical disk, which has a large capacity and can be rewritten. With the continuous improvement of software functions, more and more hard disk players support the function of database posters. The feeling of picking up a movie is really more than rummaging through the search for a disc. Except feelings. . . And with no disc storage, natural volume and cost are better controlled. The disadvantage is that it is generally believed that hard disk players at the same price are not as good as disc players. Of course, there is no difference in my entry white.

Computer: Needless to say, you can do it. What you can hate is that you can do it well. Advantages needless to say, according to a variety of plug-ins, to achieve a variety of functions. . . You can watch a movie and you can play a game on a public network. As for the shortcomings, large size, large power consumption, noise. . . In any case, for those professional and rigorous players who firmly believe that the "industry specializes", the computer will always be only a panacea. For those of me who have difficulty selecting and who are shy, often choose to use a computer, worry!

Various boxes: The network box represented by millet boxes not only supports massive network resources, but also basically has the ability to read the original disk, and has a corresponding digital output interface. The advantages are low cost, small size and high system plasticity. Love tossing can also hang a pt, like a small computer. The shortcomings, the effect is a little lower, the software is not perfect enough, there will always be a little problem. If you have a high tolerance for these, the box is a good starting option.

Game console: My God, this is not a computer. . . Can play games.

Power amplifier

In a theater system, the role of the amplifier can be described as a nerve center. (When using an active system, I did not say). Of course, the amplifier mentioned here is an AV amplifier that can decode multi-format video and output multi-channel audio. On the market, most of the AV amplifier market is controlled by Japanese manufacturers. Almost every little whiteboard who is just getting started will be told that in the av amplifier, he likes the best choice of Tianlong, and he likes to choose Marantz as the music taster. Yamaha has its own unique martial arts sound, and naturally has its own loyalty! Based on the business logic of a mature market, the principle of a penny and a piece of goods is also applicable to the market of av amplifiers. Basically the price of the product is also not too much in general.

According to my collection of data during this period (I don't know if it is accurate), I think the different levels of the amplifier are mainly determined by three parameters. They are, function, performance, power consumption!

General users are more concerned about the function , because the function mainly determines what the machine can do (good or not is another matter...) The function of the amplifier is updated quickly. What wifi, Bluetooth, 4k, panoramic sound, Odyssey, dts decoding. . . . It should be said that each function has its convenience and its significance. Whether or not you really need these functions, each function is exchanged for RMB, reducing some unnecessary functions, and you can often choose the previous model with similar power and performance at a lower price. If you don't mind second-hand machines (the virgin plot is sick, you must rule!), you can even buy the former flagship models at the mid-range price. The effect is real improvement.

Bluetooth: The most popular wireless link, but I don't think it has any use at all. When you can choose airplay, dlna and other wireless network link, you will choose to use Bluetooth?

Wifi, what equipment is there no wifi? But is the power amplifier so big you really need to move around? If it is fixed somewhere, can't you give it a wire? Don't tell me that there is no network cable behind the TV cabinet, and the line under the anchor line simply dies. . .

4k: Now the big hit, you need to consider how much energy you have to get 4k source. You have a film source, do you have a 4k projection or TV. . . . Yes, when you think about 4k, you need to rethink your budget allocation. .

Panorama sound: I don't know if this is the biggest innovation in home theater systems in recent years. In the same seven boxes, two of them were hung in the sky and the effect was earth-shaking. However, if you are just a living room party, can you accept two open lines on the roof? If you think about buying it first, you can use it after you change your house in a few years. I advise you to break this idea. When you change the house or redecorate, the amplifier technology doesn't know how far it has developed.

Odyssey: Automatic sound recognition system, almost every brand is equipped with, according to the prompt operation can monitor the acoustic status of the room and speaker placement, and automatically configure the amplifier and speaker parameters, allowing you to easily get excellent playback. If you are really stupid, or too lazy, Odyssey is reliable, but in fact, as long as the hands, manual configuration is often more suitable for your ears.

Number and type of input and output: As the hub of a home theater, the power amplifier has a large variety of devices to be connected. This time you need to consider the number of products you access and the interface category. But in fact, this is not a key indicator, because the richest family of various types of adapters to meet your various wonderful needs. In addition, I don’t think it is necessary to blindly follow up on multi-channels. It is not difficult to add more than two outputs, but adding light to the channel output does not increase the total power. The power allocated to each channel is naturally less, and the overall effect does not rise. drop.

The preamp output: The amplifier we mentioned here usually refers to the combined amplifier, which consists of pre-decoding and post-amplification. The combined power amplifier's post-class power is often not strong enough, and it is always not enough to promote high-end speakers. point. At this time, the amplifier with the preamp output can be superimposed on the pure power amplifier so that the old amplifier can be renewed and the life cycle of the product can be extended. Pure grades are relatively hedged. When the function of the original power amplifier can not meet the user, the latter stage can still match the new power amplifier and continue to play a role. If you think that you have a tossing heart, sooner or later will change the equipment to replace the gun, then I think the device to support the output of the previous level is worthy of your consideration.

Say so much, in fact, in addition to ultra-entry machines, in the new machine, these features are often all carried. The function of the machine is often used to select the old and new machine age rather than the level of grade.

High-end customers are more concerned with performance. Performance determines the effect, which is well understood. Many mid-range and low-end amplifiers support multi-channel support for next-generation decoding, but the effect of playback is not ideal. Due to the playing environment, playing materials, the system configuration varies widely. For each additional speaker, the number of operations required by the machine is increased to the power, and the machine with insufficient performance will be powerless. For example, the Marantz 7010 supports 9.2-channel output. With the post-amplifier, it can support 11.2 channel output. The Marantz 5010 only supports 7.2-channel output, plus there is no way to make it support more channels. And this is a manifestation of the difference in performance. Just like a chef, he can make good Jiangnan snacks, and he can also make half-baked full-fledged Chinese banquets. I think you are out of curiosity and will definitely let him do a full banquet, but most of the time I think you will still choose his favorite dishes. I do not know if the example I gave was appropriate. . .

Power has always been a key indicator to distinguish high-end and low-end products. Just like the car's engine. The small horse-drawn cart, although the car can also start, but the experience is certainly not good. Only by matching the engine and vehicle weight can we find a balance between effectiveness and price. And if the engine there is a certain amount of surplus, it will make the driving experience more fun dripping. Of course, if you give a Jetta top-loading twelve-cylinder engine, it may not be able to exert its effect. If you step on the door, the car will fly out. . . Of course, these feelings are all for those who have driving experience. If a person is always crowding in the subway, then what kind of car you will be able to, as long as you can cover the wind and rain, have air conditioning, can greatly enhance his life. Quality made him feel happy for a period of time.

You said that you don't have driving experience and you can't understand how I use driving experience. (Handshake, in fact, I don't have a car.) Then let's give a simple example: Say, let a long-distance runner run five kilometers, and then sing a song, then he can basically play the proper level of singing. If you let a sports enthusiast run five kilometers and then sing, it may be a bit difficult, but it can also play a 70-80% skill. If you let a trained Kirin arm otaku to run five thousand meters to go sing, I guess you can hardly hear what he was singing a. . . (Ah .. ah ... ah .. steel pot .. ah .. ah .. oh ... cry with tears ... ah ... ah .. .. .. repair scoop the pot .. ah .. . ah ...) that is all that the "distortion." If you say you are watching the film "ah .. ah .. ah .. oh .." such content, it is an example of when I just did not say anything.

About amplifier say that. Summarize the purpose of choosing a power amplifier. 1, function purchase on demand. 2, the bigger the power, the better.

Specifically

If you just want to listen to a lively event, you won't have a fever or fever, and you can buy it cheaply.

If you have a limited budget, but you know that you will enter the pits sooner or later, please choose a starter product that has a previous output.

If you have ample budget but do not like tossing, please choose the flagship consolidator.

If you have enough budget and like toss, please close this page. This article is not for you.

Digression, the main speakers here are Japanese power amplifiers. Devils are not as honest as everyone thinks. The power marked on the PA parameters was measured at low load, high distortion, and only one channel sounded. If you want two boxes to listen to low-distortion music, the estimated power is divided by two. If you want five boxes to ring at the same time, hehe, conservative estimate, the official parameter divided by three.

Audio playback system

Finally talked about the speaker. All the previous preparations are for the speaker to play its due effect. Regarding the home theater, I will not post the bitmap. The ordinary family living room party is difficult to strictly enforce the standards. It is limited to the size of space, the style of decoration and the feelings of the wives, and the effect must be compromised.

The choice of speakers is much more complicated than the amplifiers, with many brands and different styles. The prices range from three digits to fifty-six digits or even higher. As a person without too much actual experience, I dare not make too many evaluations and specific recommendations. Just talk about what I encountered in the purchase process, each beginner will entangled the problem - the choice of the size of the box.

A friend who has focused on the speakers a little bit, surely knows that the speakers can be divided into sizes, satellites, bookshelfs, and floor boxes.一般认为，主单元在小于等于3.5英寸的音箱称为卫星箱。主单元尺寸介于3.5~~6.5英寸为书架箱。而落地箱指多于两个发声单元且外形“高大”，可以直接放在地上的音箱。而在入门2000元到5000元价位区间，从卫星到落地箱套装都可以买到。于是选择上就容易纠结了。

小音箱外形别致美观省地方，大音箱造型气派有逼格。如果音箱只需要考虑外形，那选择就简单多了，而实际情况却远远不仅如此。在这里不得不介绍一些乏味的理论知识。

最基础的，我们都知道声音是靠震动发生的。小振膜轻巧，震动频率快，容易驱动高频。大振膜厚重，震动频率慢，可以发声低频。一般卫星箱的低频可以做到100hz到120左右，极少数优质产品可以把低频做到80hz左右，不过价格往往也不是入门可选了。而书架箱则可以做到60Hz左右的低频。60到120Hz的频段，包括了大多数节奏乐器的低音区，鼓，键盘，贝司等。声音偏低的男士说话，或者所谓“鼻音”也在这个频段。同时这个频段会影响到这个声音表现的“浑厚感”以及“响度”。在这个频段做的好，甚至可以让人忽略到更低频段的缺失与失真。基本上可以说，优质的书架箱已经可以满足大绝大部分音乐的欣赏。而卫星箱对于“欣赏”音乐而言，多少有些力不从心。落地箱根据单元的数量以及尺寸，低频可以低至30~40Hz，被称之为超低音。这部分超出人声范围，也仅有少数乐器可以到达这个频率。更多的时候用来表现地震，海啸等等声效表现。超低频的厉害不在于音量大小，而在于可以引起空气的震动，甚至让你感到楼体在摇动，让你的五脏六腑都震动，这就音乐发烧友说的“打心口”的低音，也是电影发烧友常说的“裤管生风”。

那么问题貌似简单了。抛开体积因素，很明显落地箱具有更全面的素质。同样的价格，买大的就对了。

too young！

我们来算一笔帐，一个音箱价格多少？抛开税费，合理利润，分销商利润，运输，存储，包装，研发等费用，余下的生产物料成本能有多少？而生产成本中，喇叭单元并不是最贵的那个，电子元件，箱体设计都是成本大头。落地箱的箱体体积是卫星箱的好多倍，更大的箱体不只物料成本增加，包装运输都是成倍增长，更要命的是，复杂的箱体结构让声学优化复杂。多单元协同发声也让分频设计变得发杂。那么，同样的价格，留给喇叭的成本已经不多。用更少的成本去做更多更大更复杂的设计，请用脚趾头想一想，效果会不会打折。

抛开价格去说喇叭尺寸是王道，都是耍流氓。不服你去听听广场舞大妈们的喇叭。

那么你又说了。落地箱成本高，我理解。那我买贵一点的落地箱呗。把音箱预算提高一倍。可以了吧。

too naive！

请回忆我上面说到的小马拉大车的故事。你把1.4t的发动机按在q7里，得到的驾驶感受会比1.4t的高尔夫好吗？

我猜你又会说。好吧，我把功放的预算也提高一倍。

too young too naive！ !

先不说入门功放预算乘以二也未必搞得定落地箱。 （入门卫星预算乘以二也搞不定什么好落地箱）当多个方向的低频信号相遇的时候，很容易互相干扰，从而造成声音劣化。想搞定这个问题，需要牛逼的功放设备，经验丰富的调试以及装修良好的听音环境。这对新手入门来说几乎是不可能完成的任务。甚至很多用户在调试了一段时间后，选择把低频直接切掉，花大价钱买来低频神器，却闲置不用，岂不是浪费？所以现在低端落地箱的外形越来越华丽，家具属性越来越强。 . .

我当初也是被论坛一些朋友怂恿上落地箱。有一种论调是，能上落地不上书架，能上书架不上卫星。我综合考虑我的状况，觉得我“不能”！那么问题来了，小音箱没有低频，大音箱低频发挥不出来。那对于入门用户，低频哪里来呢？

很多朋友心里早已有了答案：低音炮啊！

对于很多烧友“无炮不欢”，“炮是灵魂”的论调，我一开始也是拒绝的。 . . .老楼不隔音，邻居受不了。作为和谐社会好公民我不能做损人利己的事呀。不过经过在论坛学习一段时间，我慢慢懂得了炮的真谛。

第一 ，80Hz以下的低频基本失去的声音方向性。（到了120Hz就能听到明显的方向了）理论上，低音炮放在哪里响都差不多。这就是大家说的“隐身”(实际上因为空间装修的因素，各个方向的反射导致现实中，炮的位置依然免不了要调试摆位。)”。没有了方向性也就失去环绕摆位的意义，那么一个低音炮也就避免了多个方向声音互相干扰的问题，减少了调试的难度。

第二 ，低频是非常吃功率的，而低音炮都是有源的。有源的意思就是低音炮自带功放。本来就不够富裕的功率如果把低频这个包袱甩出去，自然可以更游刃有余的去解决中高频。所以，你以为你买的是一个低音炮，其实你买了一个低音炮+一个功放。我也是出于这个原因，最后选择入了一个低音炮。

第三 ，也是很多人选择低音炮的唯一理由。低音炮能够提供不主音箱强大的多的低频，爽！

那么这三个理由，总有一个理由适合你。如果条件允许，我建议您也入个炮吧。

音箱唠叨完了。总结一下。

如果你有热情，有精力，有财力，落地箱别犹豫。

如果你喜欢听点音乐，空间不是很大，预算不是很高，书架箱+低音炮。

如果你只看电影不太听音乐，空间也不大，卫星箱+低音炮也可以得到不错的效果呀。（一大波博士党赶来路上。。。）

视频回放系统

如果你是为了做家庭影院。我觉得最重要的一个指标就是尺寸。比什么色彩，对比度，分辨率等等一切其他指标更重要。说到尺寸，不用说了，我推荐投影。

主流家用投影分两大派。 3LCD和DLP两者各有利弊。 . . . . DLP的优势是成像锐利，对比度高，不烧屏。 3LCD的优势是色彩好，没有彩虹效应。

关于投影仪的介绍，张大妈有很多大神写过文章，我就不班门弄斧了。关于投影的几个基础参数，其实在我看来也不是特别纠结的事情。

色彩，亮度，对比度，黑位什么的，我都没有仔细研究过。之前的晒单也提过，其实本人最大的优点是。 . . .色弱。我对这些指标真的是不敏感。

位移功能呢，按照我的安装方式，我也是不care的。我真的觉得我的方式挺好的。等我换了大房子再考虑吊架之类的安装方式吧。

亮度 ，应该是投影的一个重要指标了。可是我也不是很care，在我看来，2000流明，白天不拉帘也看不了，拉了帘子，500流明一样看。 . .况且，我基本没有什么机会白天在家看电影。

分辨率 ，挺重要的。虽然对720p的微投我也可以接受，我甚至觉得720p的投影仪在某种程度上减轻了我下载电影的难度。不过在我朋友拿着他新买的爱普生5210来我家里测试的时候，我还是能够感觉到明显的差异。只是这种差异并不会给我的观影体验造成多大的影响。我始终觉得，当沉浸在情节中的时候，很多细枝末节就变得不再重要。无论是音乐还是电影，我都更关注内容而不是声音或画面的细节。

题外话。我本人用的是被无数“名门正派”所唾弃的微投，我不知道那些张嘴闭嘴微投都是玩具，是垃圾的朋友有多少真正的用过。在我看来，发展到今天的微投纵然在所有关键指标上都落后于传统投影，但也不是一无是处毫无优势。微投的优势就是体积小，片源获取方便，噪音小，寿命长，内置的音质也非常不错。必定不是每个人都是大片爱好者，很多人追追美剧就很幸福了。对一个租房族或预算不高的影音爱好者来说，绝对是一个不错的过渡方案。何况升级了以后还可以扔到卧室打发时间，做个廉价的wifi音箱也不会很不称职。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

我能说的就这些，其他关于沙发，线材，电动窗帘就不细说了，再说几句赶不上投稿时间了。

希望我认真写的一万多字可以帮助到一些和我一样刚刚入门的小白。说的不对希望值友指出。最后，放一张实景镇楼！
