Nowadays, more and more friends are planning to set up a home theater to watch high-definition movies at home. Many people can't vacate the room to create an independent audio-visual room. They worry that there is no shocking cinema effect. In fact, the home theater does not have requirements for the size of the room. If you don't have a dedicated audio-visual room and can only implement your home theater in the living room, it just means you need to pay attention to some problems in design, equipment, speakers and seating arrangements. After all, the living room is the living space of the whole family. And watching movies and music is just one part of it, we can only make some compromises. For many people, the best way to plan their own home theater is to imagine how powerful their home theater is, without paying attention to the cost. However, in the actual implementation process, it was found that "the ideal is full, and the reality is bone." The room most people use to install a home theater is not big. If your room is particularly small, then the next five key points are the places you need to pay special attention to. 1. The first thing to determine is the viewing distance. Many people want a big screen when they imagine a home theater, but the screen size is directly related to your room. The room can naturally be installed with a larger screen, and the room is naturally small. However, what you have to remember is that the specific size of the curtain is directly related to the viewing distance. According to THX's recommendation, the best viewing distance is the screen size × 0.84. Therefore, the screen size is the optimal distance ÷0.84. For example, if your viewing distance is 120 inches, THX will recommend you to install a 100-inch screen (120 × 0.84 = 100.8). 2. Layout speaker cable More and more Blu-ray movies are now using 7.1 channels, so you should first consider 7.1-channel speaker wiring when building. Even if it is affected by the budget, the 5.1-channel audio system can only be used for the time being, but the speaker cable should be laid out according to the 7.1-channel standard to ensure that there will be no bare wires during the later expansion. In addition, the amplifier selection prioritizes the 7.1-channel amplifier. 3. Choice of amplifier AV power amplifier is the backbone of the home theater. In addition to connecting various audio and video equipment, the most important function of this central mechanism is to push the speaker, so its "power" is very important. To put it simply, the power of the AV amplifier. Of course, this power is proportional to the price, so you still have to decide the choice of amplifier based on the budget. 4. Display device selection, WeChat: cnhifi. The display device of the home theater is of course as large as possible, but another factor, ambient light, needs to be considered. If your room has a large floor to ceiling window, then I would recommend a large LCD TV, as this may be a good choice. Of course, if your room window is not big, then the projector is definitely my preferred recommendation. 5. Projector selection If you choose a projector, you will face many choices: for example, choose DLP projector? Or LCD projector? Or LCOS projector? What is the brightness of the projector? Do you need lens displacement? Is it the choice? 3D function? Is the 4K projector suitable for purchase? Do you have some headaches? In fact, you only need to pay special attention to the following points. The first is the lens shift. This is a very important feature because it helps to install the projector very quickly and has great flexibility in the location of the projector. Followed by the automatic aperture function. At present, most projectors have some form of auto iris function, which can effectively improve the brightness and contrast of the picture. However, it is important to note that some inferior auto irises not only do not remind you of the quality, but also make the picture quality worse. The last is brightness. In principle, of course, the higher the brightness, the better, but remember that the actual projection should not be adjusted to the highest brightness, according to the actual environmental conditions (curtain size, ambient light, etc.) to adjust the brightness of the projector. More home theater technical information, all in the home theater network, official WeChat: cnhifi. Toaster, is a commonly used kitchen supplies, mainly used to bake bread. A toaster usually includes a multi-functional oven, a heat-insulating surface, a special lifting device, etc. The more advanced also includes a separable breadcrumb chassis. The toaster is a heating appliance. Its function is to generate enough heat in the vicinity of the bread to bake the bread. If there is no pop-up toaster, breakfast will certainly not be so rich nowadays.

In many families, the toaster is more prone to failure than any other small home appliance. There are two reasons for this. First of all, the toe machine manufacturing costs are generally very low, its quality is not high. You can replace a new device with just $ 10.
Second, the toaster is often not a problem when their own failure, but the food particles interfere with its normal operation. If there are too many slices of bread on the bracket, they will fall into the bottom of the toaster and accumulate when the movement of the tray will move up, thus hindering the movement of the bracket, causing the heating element to short circuit, Open the device and affect the function of the spiral tube.
Most of the pop-up toasters are equipped with a large debris plate and have a door at the bottom, the reason for this. By sliding or opening the broken door, you can clean up the food particles that accumulate at the bottom of the toaster.
