For the renovation of new houses, most audio and video enthusiasts want to set up their first private home theater in the living room. The first entry in the decoration is the hydroelectrician, they will groove the wall in the early stage, bury the pipe to be buried according to the construction drawings, and wear the specified power cord with other wires. Other cables here include the wiring rules for audio and video cables (HDMI cable, audio cable, subwoofer cable).
1. Purchase audio cables
If you are using professional HIFI audio, or theater audio, rather than background music audio, please be careful not to use the electrical cables provided by the electrician masters, which are two, three yuan and one meter on the market. Always remember to make your cable worthy of your stereo. If you really want to save money, please go to the store where you want to order audio-visual equipment and let the store buy you their worst wire. Generally speaking, the worst professional wire is ten yuan and one meter. The wire quality is relatively poor.
2. Power supply design
The home theater power supply is preferably a single-circuit power supply pulled from the main switch, and it is best to use a two-square brand international power cord, which can ensure the stability of the current. As far as possible, it should not be intertwined with other electricity, and must not be connected with air conditioners and refrigerators.
3. HDMI cable selection
Now that HDMI has reached version 1.4, the price of many cables is very different, especially for cables over five meters, the difference between the network price and the price of the physical store is really big. Some customers bought the authentic 10m wire with a market price of more than 1,000 yuan for cheap, and bought it for only 100 yuan, then used it directly during the decoration, buried it in the pipe, and found that it was unable to transmit information during installation. The decoration has been completed, the wire cannot be twitched, and it is too late to change. Because different wires have different uses, you must not say that everything will be fine after you have tried it. If you want to try it, you must try it together with the three equipment you will use in the future (disc player-amplifier-projection). If the wire is not buried in the tube, it can be replaced freely, and the wire made by a small factory can also be freely replaced because there is a problem, but if it is fixed in the tube, please avoid wire and save big trouble.
4. Line length
If you do n’t have professional guidance and you play with your own design, please let the hydropower master keep 1.5 meters long in the audio cable (including the subwoofer cable, if it is not a finished cable, and not placed in front) of the equipment (amplifier and other equipment). Only reserve 50CM. Once the equipment has a problem and needs to be taken out for maintenance, you can only pull out the plug at the back of the equipment to get it out, or lie on the cabinet and work hard. I was able to deal with good things in ten minutes, because the line was too short and wasted two or three times. If your stereo is wall-mounted or ceiling-mounted, the cable length is 30-50CM. If you are using a box-type stereo or a bookshelf box on a shelf, the cable length should preferably be 1.5 meters to 2 meters. The sound may have to be moved due to the sound quality or the layout of the living room. The audio cable would rather not be cut.
5. Tube selection
The tube from the tube device to the projection should use 40. The head of the HDMI cable is generally flat, and has 3CM, 1.5CM high, the tube is bigger, safer. In addition, the wiring must be told to the master that the end of this line can not be cut, and it can not be bent very well. It is best to use electrical tape to protect it before putting it into the tube. The tube from the equipment to the audio can be used for 20. Basically, one line is put. If the master wants the two lines to come together, it will not be a problem. I am happy with him.
The current TV in the living room is basically to be hung on the wall. You ’d better determine the size and location of the TV, let the water and electricity master bury a 50 tube, this is to take the power cord and HDMI cable, (now digital TV signals can Direct output with HDMI cable, so the cable signal line is omitted), because the power cable of the TV is generally connected to the TV, you need the entire plug through the 50 tube.
Regarding whether the material of the pipe is PVC, PVR or zinc pipe, as long as it is not discharged in parallel with the power supply, and keep a distance of more than 30CM.
6. Socket selection
Sockets Now the plugs of many audio-visual equipment are not a unified national standard. The ordinary power socket needs to be equipped with a conversion interface. It is best to use a multi-function socket at the equipment and the projector.
The number of sockets, a power amplifier requires a socket, a disc drive requires a socket, a TV requires a socket, a subwoofer requires a socket, a high-definition player requires a socket, and your iPod also needs a socket, here we need six sockets. It is best to distribute six sockets at the equipment. You should not expect a five-eye socket to put a two-headed and three-headed socket. This is rarely the case now. You often cannot use a three-headed socket if you use a two-headed socket. And vice versa. If your theater includes a projector, you need an independent five-eye socket, and it must be guaranteed to be a single road, preferably with other audio and video equipment. If you want to control this projection separately, do not put the switch and the light switch together, it is best to find a hidden place to put the switch.
