Distribution points: home theater system wiring including projector video (such as VGA, DVI, chromatic aberration, HDMI) and speaker cables. Since it is the top-of-the-home theater systems, these cables are not consecutive, a line to the end, connectors and cables are originally produced and therefore independent of other wiring system, generally only in the living room or den wiring. At design time to accurately calculate the length of the line to buy the appropriate length of cable, to ensure sufficient la place, and audio-visual equipment Center have sufficient allowance.


In wiring, to apply these expensive cable connector on one end of multilayer plastic carefully wrapped, tie up the rail line, then power-plaster and then to tie up once and traction through PVC casing, Plug one end of the pull, sent, cannot use brute force. In addition, PVC pipe can be selected larger so that they can be smooth, too, will not be stranded in the middle line.

5 AV system (candidates)

From the room by the Group of three cords access AV module panel behind the Group of terminals, the dial through Panel switch implementation on or off.


Because of this wiring circuit through continued, this is the AV system in principle not allowed, but for the sake of sharing and beautiful, the request is not very "fever-" use of the environment, can only fold, so the AV system the most important is the choice of wire rod, we want to select good enough to offset part of the wire. Video cable and audio cable should use a high-purity oxygen-free copper conductor, interface panel and AV module terminals will be 24 k gilt.
