The origin of the matter was purple sauce, and the family’s poor brand had a dark line in the lower half of the TV screen. The heart was in joy. Finally, the goods could be replaced. mentioned). Then, after a meal study, Dafa's 65 7500D was finally determined, and the group purchase price was over 7,200. However, I did not start with it. . . As for why they did not start, because suddenly found 75-inch TV is not very far, Well, the impact of the big screen is too strong. For example, Changhong (Changhong) 75G3, 9999 yuan, it is better to wait and see, under the watch to see, anyway, usually do not see much television.
In the process of watching and looking bored, I discovered that the sound system of flat-panel TVs is slag. What should I do? On the soundbar, budget inflation. . . Looks like YAMAHA's YAS-103 is the best value for money, more than 1300 will be able to hand. However, Yas-203 has a higher rating in all aspects and also has a subwoofer. The domestic price of 2500 is relatively appropriate and the budget is expanding. . . Start? Don't worry about it. The foreign assessment website has gone up and found that the best soundbar is far less than the introductory 5.1 system. So what's needed for an introductory 5.1 home theater system? You know nothing about this, but you don't understand it doesn't matter. You are studying the emperor. Work hard to study. . .
On the worth buying, on the AV199 (here forced too high, budget expansion rate can not keep up), CNET, WhatWiFi, AIU user review, Dolby official website, manufacturer's manual. . . After extensive research and study, it became clear that the original 5.1-entry home theater contained an amplifier + 6 speakers. Budget expansion. . . Yamaha RX V379 1580 yuan is the cheapest, with Harman Karton Hkts 16 2380 yuan, the best price. Ok, deal? And so on, it seems that CNET and Meiya's top rated 5.1 speaker is the Energy 5.1 Take Classic Home Theater System, which costs about 400 knives. If you edit it with CNET, it will cost you invincible price. The domestic purchasing 4800 is not shipping. . . After studying the feasibility of Haitao, it was found that the freight cost was a thousand birds. This matter is just like this, shelve.
In the process of hesitation, he found that the current popular panoramic sound system, found that this thing is good, the stereo sound of the original plane, anyway, we must toss the wiring once, not as good as. . . Budget expansion. . . Then came the topic of this article.
This article mainly shared a variety of preparations and experiences of Xiao Bai's formation of a panoramic sound system. Now we are learning to sell it now. thank you all.
================================================== ==================================
The nonsense ended and the text started.
First, what is a panoramic sound systemDolby Atmos is a new cinema audio platform developed by Dolby Laboratories on April 24, 2012. It breaks through the notion of 5.1, 7.1 channels in the traditional sense, and can combine the content of the film to present dynamic sound effects. Different from the previous one-way audio signal control theater speakers in the same side of the sound, it can make one side of the multiple speakers emit different sounds one by one, more realistic to create a far and near sound effects; with the ceiling to add speakers, to achieve The sound field is surrounded to reveal more sound details and enhance the audience's viewing experience. (plagiarized)
Simply put, the sound of the original plane is three-dimensional, and in the recording process is no longer a fixed, one channel corresponds to a speaker, but the stereoscopic position of the sound image is used on the playback device according to the number of local horns and The location is flexible to regenerate the sound field (my awkwardness). Interested students can go to Dolby's website for research. This is the authority.
The current technology of the same kind is Dolby ATMOS and DTS:X, but the commercial promotion of the latter is far behind Dolby. To date, Dolby's ATMOS technology has been used in more than 273 films.
The reason why it said more than that was because the movie list on the Dolby Web site was obviously not updated in a timely manner. Recent Sali captains and other films have not been included. Interested students can also enter keywords ATMOS on websites like RARBG to see what the latest sources are.
What do you need for a Dolby Sound System?Of course, a power amplifier + a set of speakers. (In a broad sense, there should also be audio/players and TV/projection equipment)
Power amplifier:Must support ATOMS decoding, that is, the old guys in previous years is not enough. At present, new models of Japanese power amplifiers have basically started to support ATMO and DTS:X. In line with the principle that the requirements are not high and the budget is as tight as possible, the TX-SR444 of Onkyo is initially selected. In various hesitations, at the end of October, Jingdong suddenly discovered that the goods were participating in full-scale activities. The price was 2780, which was lower than Taobao Tmall.
advantage:
1, cheap, basically the lowest Dolby panoramic sound power amplifier.
2, the function basically meets the entry requirements. Various interfaces are basically complete, with AccuEQ automatic sound field correction, standby through function (for old man operation), with HDMI ARC (not for me), with HDMI CEC (must bring function, can greatly simplify the operation), can be connected to Bluetooth Source, support HDCP.
3, sound quality is acceptable, especially to meet my needs.
Disadvantages:
1, without DTS:X, and can not be obtained by upgrading the firmware (confirmed with Onkyo official microblogging).
2, without a variety of networking features (I do not care).
3, there is no USB port (there is a USB power supply port...).
4, used to listen to songs as a general effect (originally not the strength of AV amplifier, and this is the entry AV amplifier).
5, too many buttons on the remote control, backward design, inconvenient operation.
6. The power consumption is huge after the standby function is turned on (the measured shutdown power consumption is 29 W). It is always hot.
Because it was bought more than a month ago, boxes and the like have long been thrown, there is no out of the box process, and we all bear.
Speaker:There are two options for the Dolby Sound System:
1. Special speakers with Dolby Surround sound function
Dolby Enable Speaker on Main Speaker
As shown in the figure, two or more speakers with Dolby enabled function are placed/integrated into a conventional speaker, emitting sound waves toward the ceiling, and utilizing the reflection of the ceiling to form a top sound field. The advantage is that it can be easily upgraded on existing theater systems without the need for additional speaker hanging construction. The disadvantage is that the sound field effect is not as good as a directly overhead speaker, which requires a higher listening room structure, and Dolby speakers are still relatively expensive and uneconomical.
2, composed of a number of ordinary speakers
No. 6 is the ceiling speaker
As shown, this is the minimum required Dolby panorama sound box layout. In other words, when you compose the Dolby Sound System, you need a minimum of 5.1.2 total 8 speakers. 5 represents the number of traditional surround system speakers, 1 for the number of subwoofers and 2 for the number of overhead speakers. Of course, these numbers can be expanded to dozens as needed. Let's be free.
As I said earlier, Engery's 5.1 system has come to an end, but due to the oppression of freight and tariffs, it's really not going to work. So began to swing in CNET and the United States and Asia, suddenly found another choice, the original foreigners also like to do cottage ah!
This product is exactly the copy of Engery's 5.1 system, and then the second generation of the small change because of being sued. . . Cottage system. I heard that the second generation was still accused, and then gave a sum of money to privately solve the bird.
Let's take a look at CNET's review: https://
Disassemble contrast: https://
Lifetime Frequency Response Test: https://
Https://
Imitation is exactly the same! The sound quality is blue and blue! The price is low and there is no big one! The appearance of the process is poor and does not care. This is simply a good thing to fall from the sky. Slowly, the freight rate is still more than 900, plus the tariff, it is still not worthwhile.
Tangled for a few days, the sky dropped the pie again. Prime Member of Central Asia began trial, this product is actually a member of the product (seemingly has now been canceled), Engery 5.1 that is not a Prime product (if it is, I will buy genuine). Since there is free shipping, there is nothing to say. The final tax of 1770.47 yuan won.
By the way, the front doesn't mean that you need 8 speakers, this is only 6 ah. No problem, the main speakers use the following pair, which is also free shipping for member goods (now canceled). CNET and other web sites measure sound quality better.
The final tax price of 984.23 soft sister money won.
In general, this box has basically no disadvantages other than ugliness and bulkiness at this price point. Master design, quality sound bar.
Central Asia's overseas purchase is still quite awesome. Orders are shipped the next day and they arrive 6 days after delivery. Actually, it was a single amp at the same time as the amplifier, and the amplifier waited for a week. In addition, the two groups of speakers are placed separately, because the trial orders together, tariffs actually expensive dozens of pieces, please be careful after.
other attachmentsOther accessories mainly include speaker cables, speaker hangers, speaker feet (optional), wiring slots or bayonet needed for wiring, because my Haitao speaker subwoofer is 110V, so you must also buy a transformer. All of these can be done at Taobao.
Here's everything you need to know about speaker cables: http://
The reason why we chose Huamin, but also the engineering line, is mainly because. . . poor. The speaker line is the largest expense other than the main equipment, and my wiring method is relatively round, and the length of the required cable is also long. After a long period of investigation, I decided to choose a domestic brand with a better reputation. 1.5 square corresponds to the length of the box around me. It is basically the limit. The skin of the project line is also relatively thick, and the durability is better. The actual result is also good. . Also need to carefully calculate the length of the line, consider all the corners, I bought 58 meters. In the end, only half a meter remains.
About the speaker feet, this is metaphysics, not in line with the principle I heard, but the mid-range speakers are not good there, so I bought a set of rubber pads, let it rise slightly, nothing more.
Why buy a video card? Mainly because my computer is too old, the integrated video card can't output the source code of the times. With the principle of minimum investment, 239 bought this so-called light card. In fact, it works very well. This will be discussed later when the equipment is commissioned.
Well, so far all the investment is over, let's count:
The main equipment: 2780+1770.47+984.23=5534.7
Upgrading your computer's graphics card is not included
Attachment: 349.20+88+85.5+70.8+24.34+16.5=634.34
The overall price is 5534.7+634.34=6169.04
Taking into account the different wiring lengths under various conditions, 6000 yuan panoramic sound system reached!
Third, the constructionIn fact, it is not difficult to buy things, a lot of students who are just around the corner are covered by wiring. Fortunately, my tools are fairly complete, and the ceiling of the living room is exactly where the line goes.
The advantage of the structure of my living room is that the ceiling can be routed. The sofa does not depend on the wall in the middle of the living room. It is convenient to arrange the box around it. The problem is that the central axis of audiovisual is not in the middle, and the right corridor has an effect on the acoustics. This is reflected in the later debugging (right speaker +1db).
The way to route the line is to reveal the part of the slot, with a special corner and plug, can basically reach a less obvious open line. . . There is no significant impact on the landscape and function of the living room.
Pierce the line on the suspended ceiling and block it with a wire slot. He wanted to punch holes on the wall and found that there was a thick row of wood on the wall root. It was very difficult to get through and he had to change to a more ugly position.
1942e8fcc65fbed06f10e304.jpg" />
The line walks the ceiling to the rear head box and surrounds the box.
10565 speaker comes with a screw empty fixed position, but the nut is not very strong, simply stick in the bracket and the speaker surface with sponge double-sided adhesive, this will not rotate, very stable.
This kind of zinc alloy bracket is not bad and can be adjusted in all directions. Zinc alloy material, the binding surface is a bit to block the inverted hole, sawing off is also very convenient.
The final effect:
The height of the surrounding box is 1.56 meters. It can't be lower. It will affect walking. The actual effect is that the height of the surrounding box is high, and the sound field across the entire side of the overhead speaker is also high. No way, the result of compromise.
Subwoofer position. The best way to arrange a subwoofer is to place it near the emperor's first place and then walk around the room to find the best bass sound location, which is the subwoofer position. However, in the living room, we can only make it happen. We can only plug it in here. At most, adjust the orientation angle. As shown in the figure, the resulting resonance is minimal.
Designer Andrew Jones's name, Pioneer's box, regardless of volume, workmanship, sound quality or the terminal is significantly better than 10565. you get what you pay for.
The height of the amplifier was just not put into the TV cabinet, the original factory foot was dismantled, replaced with a thin one, and kept a little bit of cooling air convection. Made a small means to raise the glass table 1cm, perfectly placed.
Wiring is a chore, requiring patience and carefulness. Don't leave too long at the end of the line. It is terrible if you accidentally short circuit it. Grinding for more than 1 hour. It is a must to make a tag on the line.
Fourth, debug power amplifier debuggingRegarding the calibration of the amplifier, I only used the AccuEQ function of the amplifier.
Note that it is best to use a tripod to place the calibration mic and place it in the ear position of the emperor to achieve the best results. Multiple calibrations are important because the sound field changes at any time as the speakers break in. For example, when I just built it, AccuEQ measured 120 points, sometimes even 150Hz. After 3 weeks of use, the same environment is the same, and the crossover point after running AccuEQ is 90Hz.
About crossover points: There are many articles and discussions on the Internet. My simple point is that no matter what your speaker configuration, the speaker size is set to be small on the right. When the LFE is input, the lowpass knob on the subwoofer is actually useless, but it is also best to rotate it to its maximum value so that the amplifier can be managed in a unified manner. The technical parameters of the frequency division reference speaker (the frequency of the 10565 is 110 Hz). I am a mashup structure and I believe AccuEQ measurement.
The volume of the subwoofer is fixed after a scale is AccuEQ calibrated. Do not move it. Subwoofer power on Auto, so far so good, do not ignore it.
For the convenience of the elderly, it is best to turn on the standby through function of the amplifier, so that even if the amplifier is not turned on, it can let the signals of the wide-area set-top box go straight to the TV. It will not be anxious to watch TV. Although this is very power-consuming when it is on standby, it is worth less than 200 yuan a year for electricity. After changing the TV with HDMI CEC, you can turn off the standby direct, let the TV and amplifier automatically switch together.
Sound source Since it is the lowest-budget cinema system, it does not consider the use of professional Blu-ray disc players and high-end players. Everything is done using the old computer next to the subwoofer. If you have the right hardware, getting the computer's source code output is still very simple.
Basically, first select the amplifier in the computer playback device and configure it to 7.1 surround sound. In the play software for some source code settings, these tutorials have a lot of online, I will not here nonsense.
Pay attention to see the audio decoder: spdif, marking the source of the output of the open potplayer
Light up the power amplifier ATOMS lamp. In fact, this time I haven't received the speaker yet, just take a job where there is YY.
Connect the speaker and successfully output ATOMS 5.1.2
By the way, the hard decoding of the graphics card was turned on again (mark: the video decoder was DXVA). No way my old computer 6 or 7 years ago was too weak and the software solution was very hard.
For non-panoramic sound sources, it is recommended that you turn on Dolby surround to use two overhead speakers. This amplifier has no DTS:X function, but for ordinary DTS sources, it is still recommended to start Dolby upmix, although not a single technology, the effect is also good.
After a month of running-in, the final result was quite satisfactory. Compared to the original TV speakers, the sound field suddenly turned on, becoming extraordinarily wide and filling the entire room. In the past, when watching TV speakers, there was always a kind of inaudible sound, or the sound of loud speakers shook up. After the theater system was used, people unconsciously turned up the volume and the sound intensity became large, but it did not put a lot of pressure on the ears. It was particularly comfortable. When playing a Dolby audio test disc, the sound field at the top is very clear, especially when it comes to rain and butterflies fly around. After watching several Atmos films, the overall effect is also very shocking, especially the action movie, the sound quality, quality and direction are very good. But compared to watching movies, the effect of this system listening to music is very general. If you really want to use it to listen to music, it is best to turn off the subwoofer.
I can say that the main job of this theater system is to watch the battle of nature, the sound of Chinese dreams, and the talented show of masked singers. . .
Radio and television 4k pilot channel, unfortunately broken TV is not 4K.
To sum up, this system has reached the standard Atmos 5.1.2 panoramic sound effect at a price of 6000, and the speakers selected by Haitao are also basically at the same level as the price level. There is no use of broken goods. As the cheapest panoramic sound power amplifier, Onkyo 444 still has many shortcomings, but for the budget from 0 to inflated over me, this effect has been quite satisfactory.
For example, the horn of the TV is a two-legged walk, with 2.0 speakers riding a bicycle. Upgrading to a 5.1 system is to open a Toyota Corolla, and the 5.1.2 panoramic sound system is Kaimeier. More advanced systems are obviously each. Kind of luxury car. The feeling of improvement from walking to driving is the greatest. If the budget is limited, then the price of 10565+ Yamaha 379=3k multiple is also good, first go to the car and say ~
The next step is to slowly wait for the opportunity to enter a 75 TV.
