Please understand how to install KTV weak current and how to wire each box. Thank you.

Generally, the network cable V0D is laid to the computer room or switch, and the VOD is laid to the TV video line, and then the control line of the central controller and the wallboard service light is laid. Note that if the video is hdmi, don't take other lines, otherwise it will interfere. Central controllers are generally divided into star wiring and hand-in-hand wiring. It depends on the equipment.
