Home theater is a complete audio and video replay system, including signal source, audio playback and video display, including the use of the environment, system components, connections, manipulation and many other content. They must be organically integrated to form a harmonious whole, and they must be consistent with people's aesthetic vision and living habits.
Therefore, it is not particularly easy to set up a high-quality home theater system that meets the requirements. What aspects of the home theater need to pay attention to? Here are some of the basic elements and key points of the cinema selection with our practical experience.
â‘ occasions <br> home theater system, home theater by definition is used, it must have a place of resettlement, living room, bedroom, study or a dedicated listening room, different environmental requirements of equipment is not the same, The open and closed space audio and video effects are also completely different. For good shading, you can consider large-screen projection. It is best not to use professional or business machines with a screen ratio of 4:3. Instead, you should use a 16:9 home projector. In bright environments, only large-size TVs are available. 9 of the 32-inch screen is the most basic requirement, if the environment allows, of course, the bigger the better.
2 Area size The size of the audiovisual area is closely related to how the equipment is selected and matched. Small rooms are best not to use large speakers, big rooms do not use small LCD TVs, this is the basic common sense of optional equipment. However, there is no absolute matter. If the equipment is carefully selected and the room characteristics are adjusted, even if it is only 10 square meters, it can also play a good effect.
3 Room ratio Do not use the room where the room length, width and height are integer multiples. Otherwise, the strong standing wave will let you do everything. The best equipment will not have a good sound in such an environment. If conditions permit, the proportion of the room can also be changed by means of ceiling, partition or floor treatment during renovation.
4 Space, acoustic processing If the upper screen projection, in addition to strict shading treatment, the room color should not be too bright, too much reflective.
5 The amount and proportion of investment is the investment in Article 5, because the environment is the most important. As for the proportion of investment, it is necessary to be flexible in adapting to local conditions. What is important is that the proportion of investment should not be too unbalanced to form a bucket effect.
6 Before pre-embedding and connecting the wire, it is best to plan the wire, including the power cable, the speaker cable and the signal cable, and set the position, as well as the lighting and control. It is best to do the acoustic treatment together. Otherwise, hanging the line everywhere can make you upset. Wire connection also has a lot of skills, but some basic principles also need to be observed, such as signal lines should not be close to the power line, speaker line; digital transmission should be clearly separated from analog transmission; wire should not be bent at an angle of less than 90 degrees A song and so on.
7 matching skills High-brightness projector with low-gain screen, low-sensitivity speaker with high-power amplifier, these are the basic matching rules.
8 equipment debugging and system adjustment When the equipment is in place, after the installation is completed, the commissioning work begins. There is no sound, no picture, you need to know the function of each piece of equipment. The sound is more complicated. In addition to the correct installation according to the cinema standard, the position and angle of the center and the surround should be adjusted repeatedly, and the subwoofer needs a little bit of movement. A little bit of trial, as well as sound absorption and diffusion processing. There are skills everywhere.
Although the above is just some experience, basic common sense may be missed. However, it can be believed that after careful matching and adjustment, not only the audio-visual effect is better, but the theater feels even better. You have become an audio-visual expert for a long time. And the endless audio and video fun began.
KNLE1-63 Residual Current Circuit Breaker With Over Load Protection
KNLE1-63 TWO FUNCTION : MCB AND RCCB FUNCTIONS
leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
