(1) Design pipeline layout.
It is necessary to specify the specifications of the threading tube, the threading tube, and the wire. The sound reinforcement system must pay attention not to walk along the line of light, power lines and other strong interference lines, pay attention to maintain a certain distance, especially in a threading pipe. Even if the same audio cable is used, the strong signal line and weak signal line should not be put in the same pipe. Threaded pipe to choose fire-resistant, flame-retardant pipe, such as fire-retardant PVC pipe, it is best to use iron galvanized threaded pipe, when used indoors, the wall can be used thin, in the outdoor use should be selected for some of the wall thickness of. If there are weak bridges in the building design, you can walk the bridge. When selecting the threading tube, the area should be left with enough margin. The area of ​​the wire occupied by the wire should not exceed 70% of the tube face, and it can be controlled at 50%. If the area occupied by the wire is too large, it will increase when the thread is actually threaded. Difficult and easy to damage the wire.
(2) Sound control room layout design.
1) The sound control room is best placed in a position where it is convenient to observe the situation on the stage, and a double-glazed window is to be set toward the stage so that the situation on the stage can be understood during the regulation.
2) The floor of the sound control room is best to use the raised floor of the computer room, so that the wiring between the lower part of the cabinet and the control table can walk from the underside of the floor.
3) The sound control room should not be too small to avoid inconvenient operation.
4) According to the number of equipment used to determine the number of cabinets, the cabinet height is best not to be too high, generally not more than 2m.
5) The cabinets should be considered for use and maintenance. There should be sufficient space for the operators to work on both sides and behind. The cabinets should preferably face the control table so that the control personnel can see the equipment on the cabinet at any time.
6) The sound reinforcement system cabinet should not be too close to the cabinet of the light dimming silicon box to reduce the noise caused by interference.
7) The console of the mixing console should be close to the glass window for observation. The sound source equipment such as the dual deck, CD player, etc. is best not to be placed in the cabinet. It is better to design it as a convenient operation position on the control table, so as to avoid operation. When leaving the control table, go to the cabinet to operate.
8) If there is a monitor speaker, it is best to fix the monitor speaker in the proper position on the control table so that it can monitor the sound effect well.
9) To have a separate switch box for the sound reinforcement system, the total power supply should not be designed too high to facilitate the power supply.
10) The power supply of the sound reinforcement system should be a separate route. Do not share the power supply with the lights. Because the lighting power supply has serious pollution, it will bring noise to the sound reinforcement system.
(3) Cabinet layout design.
1) Cabinet layout The power amplifier should be placed in the lower part of the cabinet. There should be a certain amount of space between a device and a device to ensure ventilation and heat dissipation.
2) For the layout of the cabinet to look good, decoration strips can be added between the two device panels.
3) For some devices where the front panel does not have a mounting screw hole for the cabinet, do not use a rail to install. Use a tray to install and try to fix the device on the tray to prevent the device from being unstable during operation.
(4) Route.
1) The cabling in the control room should be standardized. The cabling connected to the outside should go from the cabling trough on the wall to the cabinet and control table through the trough.
2) If necessary, leave an interface connected to the outside, such as a relay interface.
3) The cabling inside the cabinet should be neat and reasonable. Finally, the cabling should be fixed through the cabling trough or bundled to make people feel comfortable.
4) Each connection line should be marked. The traditional method is the number circle, but this method is not directly displayed. It is better to use the way to directly indicate the direction of the two ends of the connection line.
