But do you have to consider the embedded line buried in the wall and buried under the floor? If the quality of the embedded line is very poor, then no matter how high-grade wire you connect outside, it is in vain! Therefore, today we will talk about the home theater video cable, the speaker cable pre-embedding strategy and wiring skills.
Video line layout:
The video line is used to transmit video signals and is used to connect media playback devices and display devices. With the improvement of living standards and the increase of housing area, in order to pursue the visual enjoyment brought by large-screen high-definition, the traditional home theater began to transition to the projection home theater.
In general, projectors are mostly hoisted in the form of ceilings. So the best way to walk on the ceiling is to fix the trunking on the keel of the ceiling and let the decorator open a hole in the ceiling. And if you are laying on the floor under the floor, if your ground is a floor tile, it is best to pre-embed the line pipe. The function of the conduit is not only to protect the wires, but also to facilitate the replacement of the wires.
When wiring, there are generally at least three types of lines, including VGA lines, color lines, and DVI lines. Although the analog line has a feeling of being eliminated in the current digital line, the color line is the best in the current analog line, and it supports the HD standard, so it will not be eliminated in at least 5 to 10 years. In addition, although there are few HDMI interfaces at present, HDMI is a future trend, and for the long-term consideration, it is better to also put an HDMI cable.
Finally, if you want a stable power supply, it is best to install a UPS or power filter. In order to get a beautiful effect, you should hide it. This should be done at the same time when wiring, for example, it can be hidden in the beam of the ceiling.
Speaker wiring:
Speaker wiring can be divided into two situations: one is HIFI wiring, and the other is cinema wiring.
HIFI speaker cables are very expensive, so to save money, you should try to shorten the length of the cable, and this can also minimize loss and improve fidelity. Plus the speaker is also two, it is recommended that the decoration is not wired, take the bright line. The home theater wiring is more troublesome, because there are more speakers, generally around 6, the layout is not good, it will be a mess, look uncomfortable! In terms of line selection, because home theater speakers are mainly used for playing movies, the wire material does not have to be overly demanding. Generally, a 200-core copper wire can be selected.
When wiring, because the specific conditions of each household are different, it is necessary to determine the wiring method according to the specific situation. According to the acoustic law, the speakers, especially the front left front right surround speakers, are placed on the short wall side, and the sound effect is better than that placed on the long wall. Because there is no obvious directionality, the subwoofer can be placed at any suitable place on the ground in the same room, and it is generally not necessary to embed the line. To embed, usually only the surround back speakers.
In the 5.1 system, there is only one pair of surround boxes, but as a long-term consideration, it is best to add a set of two to the rear surround speaker cable on the basis of this, in case of future upgrade to 7.1 or 8.1. Channel.
When embedding the wire, whether it is in the floor planing hole or the wall grooving, the cable should be covered with a plastic sleeve or a yellow wax tube, and should not be directly sealed with cement.
