[Home Theater Network HDAV.com.cn] For the renovation of new homes, most of the audio-visual hobbies are in the living room to set up their first private theater. The first time to enter the building is the plumber. They will slot the wall in the early stage, embed the pipe to be buried according to the construction drawing, and put the specified power cord and other wires. Other wires at this time include wiring rules for audio and video cables (HDMI cable, audio cable, and subwoofer cable).
1, first, say audio wire
If you are using a professional HIFI stereo, or a cinema sound, not a background music stereo, please be careful not to use the engineering lines provided by those electrician masters, which are two or three yuan and one meter on the market. Be sure to remember that your wire is worthy of your sound (same reason, don't let your Mercedes-Benz BMW drive on a muddy country road). If you really want to save money, please go to the store where you want to order audio-visual equipment, let the store buy you the worst wire for you. Generally speaking, the worst professional wire is 10 yuan a meter, don't let them Send, send no good goods, good goods are to spend money.
2, power supply
I hope that the power supply used by your equipment is a single-channel power supply that has been pulled from the main switch. It is best to use a two-square brand international power cord, which can ensure the stability of the current. Try not to be staggered with other power sources, and definitely not with air conditioners and refrigerators.
3, and said the wire, this time is the HDMI cable
Now that HDMI has been released to version 1.4, the price of many wires varies greatly, especially for wires of more than five meters. The price difference between the network price and the physical store is really big. Some customers in order to cheap, the genuine 10 meter wire market price of more than 1,000 yuan, only used more than 100 yuan to buy, and then directly used in the renovation, buried in the pipe, installation, found that can not transmit information, change the wire Normal. The decoration has been completed, the wire can not be twitched, everything... Don't say that it was okay to try it at the time. Please note that the signals from different equipments are different. If you want to try, you must try the three equipments you will use later (disc-amplifier) -projection). Just use it. This is the case. If it is not buried in the pipe, it can be replaced freely. I don't mind if you use the wire made by the small factory. Because of the problem, you can replace it freely. If it is fixed, please do not save the line. big trouble. When decorating, most of the wire is placed directly into the pipe, or it has an elbow. When it is put in the tube, when it is stuck, it is very convenient to loosen it. But once the renovation is completed, the hidden projects are all done well, and it is very difficult to replace them.
4, line length
If you don't have professional guidance, if you play the design yourself, please let the hydropower master stay in the audio cable (including the subwoofer cable, if not the finished cable, and not in the front) for 1.5 meters. If you have a 50CM, it will cause a big problem. Once it is necessary to put the equipment in the cabinet out for maintenance, you can only dial the cable at the back of the device to get it out, or lie in the cabinet. On, hard work. In fact, if this is the case, it would take an hour or two to do a good job in ten minutes. The difficulty is that the line is too short. If your sound is wall-mounted or ceiling-mounted, the line can be 30-50CM long. If you use a box-type stereo or a bookshelf on the shelf, the line length should preferably stay 1.5m-2m. The sound may be moved because of the sound quality or the layout of the living room. And it is really long, this line can also be cut. You must understand that the audio cable would rather not be cut.
5, the pipe
The tube to the projection should be 40. The head of the HDMI cable is generally flat, and has 3CM, 1.5CM high, and the tube is bigger and safer. In addition, the wiring must be told to the master, the head of this line can not be cut, can not bend very powerful, it is best to use electrical tape to protect, and then put into the tube. The equipment to the audio tube can be used for 20, basically put a line, if the master wants two lines to come together, there will be no trouble, with him happy.
The TV in the living room is basically to be wall-mounted. You should decide the size and position of the TV, and let the hydropower master bury a 50-tube. This is the power cable and the HDMI cable. (The digital TV signal can now Direct output with HDMI cable, so the cable signal line is omitted), because the power cable of the TV is usually connected to the TV, you have to pass the entire plug through 50 tubes.
Regarding whether the material of the pipe is PVC, PVR or a zinc pipe, as long as it is not discharged with the power source and kept at 30 CM or more, it is sufficient.
6, the socket
Nowadays, the plugs of many audio-visual equipments are not unified national standards, and ordinary power outlets need to be equipped with another transfer interface. If the socket is set at the time, we will leave our mind that there will be no problem with the multi-function socket in the equipment and projector.
The number of sockets, the amplifier needs a socket, the disc player needs a socket, the TV needs a socket, the subwoofer needs a socket, the HD player needs a socket, and your iPod also has a socket. Here are six sockets. There may be some you can't use, maybe you have more equipment, but I think you'd better discharge six sockets at the equipment. You'd better not expect a five-eye socket to put two heads plus three heads. This situation is rare now, and often two heads can't use three heads, and vice versa. 8. Projector If your theater includes a projector, you need a separate five-eye socket, and you must ensure that it is a one-way road. It is best to follow other audio-visual equipment. If you want to control this projection separately, don't put the switch and the light switch together. It is best to find a hidden place to put the switch.
It is best to leave 50CM for the HDMI cable at the projector. It is better to draw the cable.
7, the line
The outlet point of the audio and video cable, please do not use the bottom box + panel outlet, the hydropower master to do, is the most real, the best, directly out of the pipe. Don't do bad things with good intentions. The wall of the sound wall, if the pipe is directly out of the line, the sound can be easily blocked when installing the 20 tube, there will be no exposure.
