1. Cheap, low-end inferior wire
The significance of wire for home theater is like the importance of blood vessels to the human body, but many whites do not understand this. Just buy some cheap wire on Taobao, or directly use the wire provided by the decoration company. This low-end inferior wire is generally used in the unit to make a conference room. Anyway, you can make a sound. However, your home theater was developed to show the details of the sound of the film. The inferior wire is enough to ruin it. The sound is rough and harsh. It feels like a gorgeous sexy girl, but Wearing a dozen pieces of goods to spread the color underwear.

2. The sofa is against the wall, but it gets a 7.1 channel.
The more the number of channels, the stronger the immersion of watching movies, but some people do not understand the applicable conditions of multi-channel, blindly hard. One of the most common mistakes is that the sofa is against the wall but has a 7.1 channel. Why can't this be because the so-called 7.1, on the basis of 5.1 surround sound, adds two speakers behind it to express the sound from the back in the movie. Then if your sofa is against the wall, the two added rear speakers are placed in a position that is flush with you. What does this mean? If there is a ghost in the movie chasing you from behind, and what you hear is From the side, the sense of orientation logic is completely wrong, so 7.1 is better than nothing.
Wrong pendulum
3. Renovation without pre-embedded backup HDMI cable
The HDMI cable is mainly composed of copper wire. If there is damage inside the wire, the data cannot be transmitted smoothly. In addition, the wire is generally buried in the wall, it is very troublesome to replace, so it is best to bury two, one of which is used as a backup. If you don't think you want to spend a few hundred dollars more, you can do a very calm wall-breaking line when you have a problem.
Correct wiring
4. The HDMI cable interface is not protected during the decoration.
If you are hoisting the projector, you need to embed the HDMI cable in the wall. The HDMI connector is very expensive, but the indoor dust pollution is serious during the decoration. The delicate data interface is easy to damage. The solution is to wrap the connector with plastic bag and tape. Ok, wait until the end of the renovation, then unravel it. Don't throw this part to the decoration worker. This part must be supervised and constructed by yourself. As far as the current national conditions are concerned, don't expect too much for the decoration workers, if the interface is damaged. The wire is wasted, the projector can't be used, the line has to be demolished, and it's too late to cry.
Right way
4. Side ring mounted back wall
In the 5.1 system, in addition to the first three speakers, there are two side surrounds. As the name suggests, the side surround is mounted on the side wall, the unit of the horn is facing the human ear, and the side ring is 1.7 meters away from the ground. However, some users and companies are not professional. I take it for granted that the side surround is installed on the back wall, and the speaker audio unit is facing the front TV wall. In this way, the sound on the side is emitted from the back to the front, while you are sitting on the sofa, the sound on the side becomes very unreal.
Wrong pendulum
6. Subwoofer
Since people are not sensitive to the directionality of the bass, the subwoofer can be placed in the corner. But there are two things to note:
Subwoofers should never be placed on objects that are prone to resonance, such as tables and cabinets. Once this is done, when the subwoofer is working, the table will also vibrate, which has a great impact on the sound quality.
Do not cling to the rear of the subwoofer. This is because many subwoofers are designed with a rear phase inversion, and the inverted phase holes are facing backwards. If there is no certain distance, the effect of the bass can not be exerted.
Therefore, at least a distance from the wall.
Wrong way
7. Commercial speakers and projectors for home use
Some Xiaobai thinks that as long as the speaker can make a sound, you can watch the movie. As long as the projector can watch it, you can put the movie. Is this wrong? It is like a tractor can also be loaded. The car can actually pull coal. It can do it, but it has no professionalism and low efficiency. Commercial speakers are mainly used on the stage, and those are big places, so the sound of the speakers is required to be large enough. As for the beauty of the sound, how much detail can be reflected is not a category considered by commercial speakers. As for commercial projectors, people use PPT. You use movies to watch movies. It is not enough resolution, or the brightness is too high and the picture is white. Please remember that there is a specialization in the industry, so don't be hard-pressed.
8. Main box and surrounding the Eight-Power Allied Forces
Speakers are also of pedigree, a set of speakers is best to be a unified brand, the main box, center, side surround, rear surround is best the same brand of products, in order to ensure that the sound is consistent. Some friends think that the main box of a certain model is bought, and then I feel that the other side of the brand is cost-effective, and bought it. Then a home theater becomes the Eight-Power Allied Force. This configuration, even the best speakers, the sound heard will not be beautiful.
9. Small horse cart
The power amplifier is like the engine of a car. It is very important for performance. Many white people don't understand the function of the power amplifier. They think that the speaker has to buy a famous brand, it is worth spending more money, and the power amplifier can be used. But this is completely wrong, because in the home theater system, the speakers are generally passive speakers, that is, there is no power supply, and the power is transmitted through the speaker cable by the power amplifier to push the speaker unit to sound. The potential of the speaker needs to be released by the appropriate power amplifier. Can you imagine a 1.5L engine for a sports car? It is not to encourage everyone to use high power consumption, but to make a reasonable match.
10. The middle is plugged into the TV cabinet.
In the home theater system, it is responsible for the dialogue of characters in the movie. The high-quality center can restore the dialogue of the characters in the movie. The characters are round and vivid, deep and powerful, and you can feel the charm of the sound. As a result, some people put the center in the TV cabinet for the so-called clean environment. Can the occluded speakers make a good sound?
