Home theater video and audio line pre-buried and wiring skills

With the continuous progress of technology, audio and video enthusiasts on the effect of the equipment requirements are constantly improving, and the continuous upgrading of equipment on the requirements of the wire will also increasingly upgrade. Therefore, video cables, speaker cables and power cables also increasingly need to withstand the test. However, in practice, many entry-level audiophiles have not put enough attention to the wire, often the power plug of the equipment to the home socket a plug, do a professional point is to use a power filter at the plug outlet, and that’s it. But do we have to consider buried in the walls, buried in the floor under the pre-buried wire? If the quality of the pre-buried wire is very poor, then no matter how high-grade wire you connect outside is also in vain! So, today we will talk about the home theater video line, speaker line pre-buried strategy and wiring skills.

Home theater wiring

Video cable layout.

Video cable is used to transmit video signals, which are used to connect media playback devices and display devices. With the improvement of living standards, the increase in housing area, in order to pursue the visual enjoyment brought by the large screen high definition, the traditional home theater began to transition to projection home theater. Generally speaking, the projectors are mostly in the form of suspended in the ceiling. So in the ceiling alignment is the best choice, as long as the wire channel fixed in the ceiling keel, and then let the renovation workers in the ceiling above the opening of a hole on the OK! And from the floor under the line, if your floor is paving tiles, wiring is best to pre-bury the line pipe. The role of the line pipe is not only to protect the wire, it also has a convenient function to replace the wire.

When wiring, generally at least three kinds of lines, including VGA lines, color difference lines, and DVI lines. Although the digital line is popular now, the analog line has a feeling of being eliminated, but the color difference line is currently the best analog line, and it supports the HD standard, so at least in 5 to 10 years will not be eliminated. In addition, despite the current HDMI interface is less, but HDMI is a future trend, for long-term considerations, it is best to also cloth on the HDMI cable.

Finally, if you want to get a stable power supply, it is best to add a UPS or power filter. To get an aesthetic effect, you have to hide it, and this should be done at the same time when wiring, for example, it can be hidden at the ceiling beams.

Speaker wiring.

Speaker wiring can be divided into two cases: one is HIFI wiring, and the other is theater wiring.

HIFI speaker wire is very expensive, so to save money, we must try to shorten the length of the line, but also to do so to minimize the loss and improve fidelity. Plus the speakers are only two, it is recommended that the decoration is not wired, take the open line can be. And home theater wiring is more trouble, because the speakers are more, generally in about 6, the arrangement is not good, it will be a mess, look uncomfortable! In the selection of lines, because the home theater speakers are mainly used to play movies, so there is no need to be overly demanding in terms of wire, the general choice of 200-core copper wire can be.

Wiring, due to the specific circumstances of each household is not the same, according to the specific circumstances to determine the wiring method. According to the laws of acoustics, the speakers, especially the front left and right surround speakers, placed on the short wall side, the sound effect is better than placed on the long wall side. Subwoofer because there is no obvious direction, can be placed in the same room at any suitable place on the ground, generally do not need to bury the line. To bury the line, usually only the rear surround speakers. In the 5.1 system, the surround box only a pair, but as a long-term consideration, it is best to lay more than one group to two groups of rear surround speaker line for future upgrades to 7.1 or 8.1 channel.

Buried line, either in the floor planing pits or in the wall groove, you should use plastic casing or yellow wax pipe to set the line on, do not directly use cement to seal.
