Private home theater is a private space where people enjoy life and experience the entertainment atmosphere at home. In actual life, many people have designed this private space as a multi-functional audio-visual entertainment room; it is a combination of watching movies, listening to music, singing karaoke, and game entertainment. In this movie, K-song is big. Most people choose the combination, which will cause many people to ask questions. The KTV room and the movie room are different in acoustic characteristics, and the two functions are combined in the same private theater, and the acoustic effect is not required. Conflict? How do many private homes in the country solve the acoustic problem? Second, to create a private home theater and KTV space-sharing acoustic processing skills.
In the process of creating a private home theater and KTV space, how to transform some key elements, and can be carried out in relative savings?
To create a room combining traditional KTV with a private home theater, pay attention to the following issues in acoustic processing:
One: Jiansheng treatment: avoid excessive hard surface-based decorations, such as large-area glass, stone, etc. This decoration is too strong for high-frequency reflection, which will affect the clarity of multi-channel cinema sound. Increase soft sound-absorbing sound absorbers, such as soft bags, fabric sofas, etc., to reduce high-frequency reflections. If the diffuse reflection type diffuser and the corner low frequency trap and other sound building devices can be properly used, the effect is better. There are also sound insulation effects such as doors and windows to be taken into account, so as to avoid the sound leakage affecting the viewing effect of the adjacent room.
Avoid the use of large areas of glass and stone, and use fabric and soft bags.
Second: speaker placement and high-frequency compensation: private home theater multi-channel speaker placement, try to follow the principle of the speaker's positive axis aligned with the listening area, so as to ensure the sound details and sound field reduction. If the speaker position needs to be placed in a higher position due to conditions, try to use an adjustable angle bracket, or use an angled directional speaker specially designed for the theater to point the horn positive axis to the listening area, with The AV receiver with automatic tuning function (such as Tianyi's HD decoder and amplifier with HD decoding function has automatic acoustic test function), performs frequency calibration to compensate for the loss of high frequency response.
Third: the bass position and adjustment: the private home theater ultra-low speaker position should be as close as possible to the front main channel speaker, which is conducive to the phase connection between the low frequency and the main speaker, improving the clarity and strength of the low frequency. Try to avoid placing the Subwoofer in the listening area next to the sofa and away from the main channel, which will increase the difficulty of sound adjustment. If there is a serious low-frequency standing wave in the room, you need to increase the low-frequency trap; if there is low-frequency offset, the side needs to reduce the large hollow objects (such as cabinets, empty walls, etc.) that exist in the room, and cooperate with the AV with automatic tuning function. The receiver performs frequency calibration to reduce the impact.
Fourth: Optoelectronic system isolation: If the room has strobe lights, laser lights and other effects lamps in use, then it is necessary to pay attention to separate the lamp circuit and the audio circuit, not the same phase in the power supply line, to avoid the pulse generated when the lamp is used. Interference with the home theater sound system.
