When the user carefully designs and carefully selects the home theater that is built, the effect is not up to expectations, which will inevitably disappoint. Before you want to find a professional audio-visual designer to adjust the home theater effect, do you notice some details in the audio-visual room? Handling these details may improve the user's home theater effect. Share 10 tips or notes below. Matters, the effect will definitely improve.
Detail 1: "Subwoofer" enhances low frequency performance
The subwoofer, which we call the subwoofer, is a subwoofer channel dedicated to low-frequency effects. Some users' home theaters may not have such a speaker, and only use the woofer of the front speakers to express the sound. The low-frequency details, in fact, will lose many of the important elements of the film's shock, adding a subwoofer can improve the system's low-frequency performance.
There are also some users who have already configured the subwoofer, but the effect of low frequency performance is still not satisfactory. This may be because the optional subwoofer power can not fill the audio and video room space, so that the low frequency performance is insufficient. At this time, the user can add a bass. Cannons, two subwoofers can complement each other, making the low-frequency performance of home theater more adequate.
Detail 2: Pay attention to the placement of the speakers
Home theater audio is an important part of home theater. Its authenticity of sound reproduction is an important criterion for evaluating the audio performance of home theater. The quality of sound reproduction of the speaker is not only the playback performance of the speaker itself, but also the speaker. There are also inseparable relationships.
When we watch a movie or listen to music, we will feel that the transmission of the sound is not accurate. At this time, we can consider whether the speaker is placed in the wrong position. The user can adjust the position of the speaker and shift the direction of the speaker to adjust The direction in which the sound plays.
Detail 3: Stabilize the equipment
The placement of equipment and equipment must first be stable. If it cannot be placed stably, the equipment will generate noise and resonance due to vibration when the equipment is working, which will affect the signal transmission and sound quality. It's a good choice to put the equipment on a dedicated audio-visual equipment rack. This will not only make your home theater look neat, but also place the equipment on different layers of the equipment rack to avoid mutual interference caused by stacking equipment. And the rigid equipment rack also allows the equipment to be stable while working.
Detail 4: Power matching
The power between the various devices in the home theater audio system should be matched. If the output power of the amplifier is small, when the speaker volume is increased, the large dynamic peak signal that appears in an instant will overload the speaker, and the sound will be unreal and noise. Therefore, the matching between devices in the home theater audio system is one of the importance of building a perfect home theater. If there is a power mismatch, increase the power of the amplifier, add an amplifier or replace a larger power. Amplifier.
Detail 5: The speaker should be placed firmly
We said earlier that the placement of the equipment should be stable, and the placement of the speakers also needs to be stable and firm. When the speaker is working, there will be a large amount of energy released. If the speaker is not stable, there will be resonance and other conditions, which will affect the listening effect. Users can add a sturdy tripod to the speakers or place the speakers on the rug to eliminate the resonance of the speakers.
Detail 6: Choose the right size screen
Without a large enough visual effect, there is no shocking sound and picture performance, so it is really necessary to use the largest possible screen in a home theater.
The choice of home theater projection screen will directly affect the overall effect of the home theater. This is well known, but when choosing a home theater screen, the user is not the bigger the better, but the size of the screen is determined according to the size of the user's home theater and the projector. . Imagine that when your projector and the screen are only 3 meters away, you can choose a 180-inch screen that requires a projection distance of at least 6 meters. This is a big waste, and it does not reach the projection screen that users expect. Effect.
In addition to paying attention to the size of the screen, the choice of projection screen ratio and screen material should be cautious. To see how many screens to watch, choose a projector and screen that can project such proportions. Of course, this depends on the current mainstream video. Many people like to watch a 2.35:1 widescreen movie, but now the widescreen video program. The source is very small, mainly 16:9 movies, so most users will still choose a 16:9 projection screen. The material for the curtain is determined by the brightness of the home theater space environment.
Detail 7: Easy to control lighting
The suitable lighting environment will also have an impact on the home theater experience. When we watch the movie, the brighter the light in the room, the worse the visual sense of the picture. When we listen to music or K songs, the brightness of the room is suitable. Will affect the comfort of our entertainment. The single-function home theater space will be equipped with a switch to control the indoor lighting next to the entrance door. Because the room function is relatively simple, the lighting environment only needs one mode, so the home theater is better handled. For the multi-functional audio-visual entertainment space, only one mode of ambient light system can not meet the needs of users. When we listen to music or K-song, we will not use the full-dark mode when watching movies. The multi-mode lighting system is very important for a versatile home theater studio. Nowadays, many home theaters are equipped with intelligent control systems. As long as they use handheld devices, they can control a series of operations such as equipment and lighting in the audio-visual room. Users can set the lighting system to theater mode, karaoke mode, admission mode, etc. The mode is convenient and fast to meet the user's multi-functional needs.
Detail 8: Choose a comfortable cinema-specific sofa
Many users pay great attention to home theater equipment and decoration, but the choice of seats is very casual, think that the sofa or the seat does not matter, choose the same sofa as the living room, no need to spend more to buy special Cinema sofa. In fact, the home theater sofa and the ordinary living room sofa have different appearances and functions. In addition to the seat function, the theater sofa also has its own electric system. This system can provide users with a series of auxiliary home theaters. Features such as adjustable seat angles, reading lights, beverage cooling, and motion systems. When we watch a movie, we usually have to stay for about 2 hours, which will make our body fatigue and reduce our viewing effect. The adjustable seat of the cinema sofa can help us relieve fatigue. The operation keys of the various functions of the cinema sofa are all at the armrest, and it is also very convenient to control.
Detail 9: Bi-amp mode
Conditional home theaters can use dual-amp mode, of course, the user's speakers must have a two-line crossover. The bi-amp mode uses two amplifiers to push the midrange and the bass respectively. This can reduce the distortion of the sound and the loss of power. Compared to a single amplifier, it gives us a more pleasant sound quality.
Detail 10: Isolating individual equipment
The isolation mentioned here is to isolate the vibration of your equipment (including the speakers) from the outside world (in terms of the equipment itself), such as the isolation of the equipment from other equipment, the isolation of the speakers from other sources of vibration, and so on. The internal vibration of the equipment working, adjacent to the vibration of other equipment or the external vibration source, will produce vibration coupling, noise and noise, which seriously affect the effect of our appreciation of sound, so we must isolate these equipment and vibration sources, use air suspension Means are a good way.
