济南音响相位问题的解决方法

在多只话筒中，首先确定一只真实相位相同的话筒，将这只话筒作为基准话筒。一般来说，在所有济南音响之间为同相关系的情况下，同一型号话筒中拾音效果相对最好的那只话筒肯定是真实相位同相。确定了真实相位同相后，将被检查话筒与基准话筒的头部紧靠在一起，用话筒拾取同一声音，输出音量声源音量增加而增加的为同相，否则被检查话筒为反相。重复以上步骤，就可以检查出所有的反相话筒。
In more than one microphone, first determine a true phase the same microphone, this microphone as a reference microphone. In general, among all Ji'nan audio for in-phase relationship, with the same type of microphone pickup effect is relatively the best that microphone is certainly true phase phase. To determine the true phase phase, will be examined and the reference microphone microphone head close together, with the microphone pickup with a voice, the output volume sound source volume increases for in-phase, otherwise be checked for inverting the microphone. Repeat the above steps, you can check out all of the inverting microphone.
对于反相话筒，有两种解决方法：一是打开反相话筒线卡侬插头，将卡侬插头的2、3端对调；二是如果调音台设有倒相键，可将反相话筒信号输入路的倒相键按下，相位就调换过来了。
For inverting the microphone, there are two solutions: one is to open the inverting microphone cable connector, 2, 3 end switch connector; two is the if mixer is provided with inverted phase keys can be reversed, the microphone signal input road phase inverted key press, phase change over.
济南音响调音台相位。 一般调音台设有φ键（即倒相键），相位转换开关，在使用不同型号的几支话筒平行拾音时，如果发现声音异常或偏弱，可以将其中一个话筒通道的相位转换开关按下去判断是否相位问 2/3 题引起。另外在两只相位正确的音箱同时发出声音时，因为指向角度，摆放位置，离听众距离等因素的影响而导致的声像漂移，其实也可以列入“相位”这个范畴里讨论的，只不过它是两只箱的声音到达人耳不同步而单个音箱是高低音喇叭的声音到达人耳不同步。这个问题也可以在调音台上有个专用的声像电位器来平衡处理。
Ji'nan audio mixer phase. General mixer is provided with a Phi keys (i.e. inverting key), phase switch, sound pickup parallel in several microphone using different models of the time, if it is found that the abnormal sound or weak, can be one phase of a microphone channel switch press down to determine whether 2/3 induced phase asked questions. Also in the speaker two phase correct and sound, because the pointing angle, location, image drift influence factors such as the distance from the audience caused, in fact can also be included in the "this category phase" in the discussion, but it is two box sound reaches the ear not synchronous and single speaker is high bass the sound of the horn to human ears are not synchronized. This problem can also be in the mixer has a special image processing to balance potentiometer.
济南音响功放相位。 两入两出功放的输出模式有两种：一是有四个接线端，分别有两组红（+）黑（-）接线端子），二是四芯插座（±1、±2）。 如果是第一模式的连接方法，四个接线端，则较容易理解正负极，输出插也有明显的红黑二个端口供辨认，但当功放使用桥接以后，注意信号输入控制（通常为A通道）的红端为正极，另一输入控制（通常为B通道）的红端为负极。 6、音箱单元相位。
Ji'nan audio power amplifier phase. Two in two out of output mode power amplifier has two kinds: one is to have four terminals, respectively, two groups of red (+) and black (-) terminals), two is the four core socket (+ 1, + 2). If you are connecting method of the first mode, the four terminal, it is easier to understand the positive and the negative poles of the output plug, also has the obvious red two ports for identification, but when the power amplifier using the bridge, the attention signal input control (usually A channel) of the red end is positive, another input control (usually B channel) red end is negative. 6, the speaker unit phase.
