音响工程是布局室内/室外演出、家庭影院、会议扩声的关键项目,也是组建碍罢痴包房系统的关键。下面我们就和大家介绍一下山东音响布线技术中音响地线的分布知识。
Sound engineering is the key project for the layout of indoor / outdoor performances, home cinemas and conference sound reinforcement, and also the key to the establishment of KTV private room system. Next, we will introduce the distribution of audio ground wires in Shandong audio wiring technology.
一、音响地线分布的注意细节
1、 Pay attention to details of distribution of sound ground wire
1、有一些电路既有小信号输入端,又有大信号输出端,而通常输入,输出的均由面板交割。如果输入与输出都有接地点的话,它们的接地端务必分别用导线到公共地线上,而不能共用一根接地线。
1. Some circuits have both small signal input terminals and large signal output terminals, and usually the input and output are delivered by the panel. If both the input and output have grounding points, their grounding ends must be connected to the common ground wire by wires, instead of sharing one grounding wire.
2、如果在实际的电路布接中,各级的接地元件多,不可能将这些元件都穿入一个穿线孔中,而是将本级接地元件尽可能就近安排在公共地线的一段或一个区域,也可以从地线上引出接地分支或接地岛。
2. If there are many grounding elements at each level in the actual circuit layout, it is impossible to put all these elements into a threading hole. Instead, the grounding elements at this level are arranged in a section or area of the common ground line as close as possible, and the grounding branches or grounding islands can also be led out from the ground line.
3、地线布局的合理与否决定:地线中的电流是否流经了与此电流无关的其他电路或部件。
3. Whether the ground wire layout is reasonable or not determines whether the current in the ground wire flows through other circuits or components unrelated to the current.
4、在安排大功率音频输出级,由于输出功率块和滤波电解电容等元件体积较大而需装在板外,就应将这一些元件的接地点与本级的板内电路的接地元件做到一点接地。
4. In the arrangement of high-power audio output stage, since the output power block, filter electrolytic capacitor and other elements need to be installed outside the board due to their large volume, the grounding points of these elements and the grounding elements of the circuit in the board of this stage shall be grounded at one point.
5、地线的分配应该以地址中的电流为依据,既互不相干的电流不能合用一根地线,允许在一根地线中通过的电流不能用地线分开。
5. The distribution of the ground wire shall be based on the current in the address, i.e. irrelevant currents cannot share one ground wire, and the current allowed to pass through one ground wire cannot be separated by the ground wire.

二、当有各种信号通路和输出导线到板内布线时,为了防止寄生耦合,应做到下列几点:
2、 When there are various signal paths and output wires to the wiring in the board, in order to prevent parasitic coupling, the following points shall be achieved:
1、信号线在排版时应避免相互靠平行排列,特别是在处理内跨线和双面印制时,要注意使两面的导线呈垂直或交叉,不能平等。
1. The signal wires shall not be arranged in parallel with each other during typesetting, especially when dealing with internal cross wires and double-sided printing, the wires on both sides shall be vertical or cross, and shall not be equal.
2、各级间的信号走线越短越好。
2. The shorter the signal routing between stages, the better.
3、遇到板内需平等设的信号导线,应使这些导线尽可能间隙一定的距离,或用地线,电源线隔开,达到屏蔽的目的。
3. In case of signal wires that need to be set equally in the board, these wires shall be spaced as far as possible, or separated by ground wires and power wires to achieve the purpose of shielding.
4、各级电路在排列时,要按照信号的顺序排列,不能迂回或级排列,这样可避免各级之间的信号线相互跨越。
4. When arranging the circuits at all levels, they shall be arranged in the order of signals, and shall not be circuitous or arranged in stages, so as to avoid the signal lines between the levels crossing each other.
