Annotation: Cinemas do sound field processing, focusing on the transformation of the sides of the room, the top, the ground and the corners. On both sides of the wall, the most important part is the height of the bottom half of the wall is 1 meter, do key processing, can do wooden skirts height of 1 meter, the wood is a certain distance from the wall, the gap is filled with foam or asbestos can also It is a sound-absorbing sponge. Wooden walls can also be shaped (such as: wave lines or bumps, etc.). The upper half of the wall can be brushed and brushed to effectively disperse the sound waves. Or there are conditions to make both sides of the wall bookcase / CD / DVD / bookshelf open from bottom to top. It is also an effective diffuser. There are two ways to deal with the top of the 1 ceiling 2 wall modeling (such as: wave or diamond-shaped protrusions). Some air conditioners have to be dealt with. The air outlet can be reinforced to avoid resonance. Ground treatment is very important to do composite wood floors, it is best to lay wool carpets in front of the main speakers and sofa, wool thickness 2.5CM best. Corner treatment can reduce the subwoofer's rumbling sound and reduce the sound staining. The specific method is to make the corner into a circular arc shape, and make a cylindrical shape with plaster, which can be filled with foam or asbestos can also be a sound-absorbing sponge. The back wall can do 1 meter wall skirts, the upper part can do soft packs, and the door should also be made into soft pack doors. Note: Do not do too much processing inside the room, because the audio frequency is too long, there will be no way to change it in the future, the sound field is properly processed, and the sound dry reverberation time is too short, we can add sound-absorbing Things. Such as: plush wall hanging and so on. The subwoofer can be placed on the left or right side of the main speaker. The lines of the main speaker line, center speaker and subwoofer do not need to be embedded. Now the most important thing is that the surround speaker cable and video cable must be embedded in a fixed position. Projector position is very important, because the H77 lens is partial, to consider the center of the lens is the right curtain, the method is to set the center of the curtain, the installation of the projector to extend 5 meters (projection distance of 5 meters is the lens to the curtain is 5 m), the machine size is 430*305*135, so the hanger position is 5.153 meters. Now find the center of the machine (remember this time is not the lens alignment, because the lens is biased) to move the machine 107.5MM to the left. At this time, the camera is in the center of the curtain. However, the point where the projector is installed is shifted by 107.5 MM. About the exit position of the ring and the rear ring and the location of the speakers. The left and right middle ring outlet positions are based on the viewing distance and the placement of the sofa. The viewing distance is set at a distance of 4 to 5.5 meters, which means that the central position can be placed on a 4.2 meter position and the speaker is 300 mm away from the wall. The rear loop exit position can be placed at 5.8 meters. The speakers can be placed on the back of the three-seater sofa. The two sides are 1.1 meters away from the back wall. The speaker cables are drawn from the power amplifier. The power amplifier is placed there. The line is drawn from under the wall. The video cable is led from the DVD. It is usually put together with the amplifier, so the line should also be led under the nearby corner. . The method of laying wire rods is based on the principle of one line and one pipe. Do not go to the dead end. Some finished lines need to put the line on the tube after being thrown away, and then seal it and bury it. (You must buy the wire in advance. After the wire is buried, seal the end of the finished product to prevent damage.) Kikuchi border curtain size is width: 2852MM height: 1650MM. It is recommended to leave 2860*1660 Curtain curtains can be designed on the curtain. The bottom of the curtain 700MM is the best location off the ground. Audio and video cables belong to the weak electricity and the strong electricity should be buried separately, separated by 300MM, not to cross. The projector is suspended from the ceiling. If there is a ceiling, the hanger must be installed beforehand. Install the power supply board near the projector and install the power control switch at the convenient place below the wall. It's easy to power off after watching movies and power off. All wires must be at the exit, leaving a corresponding number of lines (500mm-1500mm).
