Behringer UB1622FX调音台作为一个现代乐手，经常会见到调音台。

就是那种有无数旋钮，还有各种开关，看上去样子很吓人的设备。

一个号称音响师的家伙躲在调音台后面，也不知在忙些什么。

如果他是个高手，你的演出会非常爽！或许你很好奇，但是不会介意自己不会使用调音台——那是专业设备嘛！不会用是应该的。

不过现在越来越多的朋友想在家里给自己录小样，开始玩电脑音乐。

于是总会使用到各种调音台。

什么模拟的、数字的，音频接口里也可能有内置的调音台界面，还有那些似乎更加摸不着头脑的音频软件的调音台。

总之到处都会找到调音台的影子。

很多朋友觉得调音台很复杂，弄不懂。

搞了半天甚至没有声音，郁闷！或者不懂原理，错误的使用调音台，使它没有发挥应有的作用。

想要学习一件事物，我们首先应该知道这个东西到底能够作些什么！我们能用调音台做些什么事情呢？大致可以有如下几项：一. 调音台能够放大输入通道的信号，并且调整输入声音的均衡（EQ）,甚至其他效果，比如压缩等等二. 调音台可以把很多声音的混合起来组成一个立体声！三. 调音台能为乐手和演员“返送”监听。

四. 调音台协助效果器为各个通道添加混响、延迟等效果五. 调音台把各通道的声音发送给多轨录音机或者音频接口分轨录音调音台能够可以让录音师很方便的监听所有通道的声音，并且并不干扰这些通道。

. 六实践是学习调音台的最好方法。

我们以市场上比较常见的Behringer UB1622FX模拟调音台为例，介绍调音台的基本功能和使用方法。

这个UB1622FX调音台虽然体积不大，但是功能比较全，还内置了一个数字效果器。

首先声明我不是Behringer公司的“托儿”，我只想用一个具体的例子让大家了解调音台的一些基础知识！知识是相通的，只要掌握了调音台的基础知识，就可以很快掌握和使用各种各样的调音台，无论是模拟的还是数字的，甚至是那些虚拟的调音台，都能很快上手。

下面我们就结合Behringer UB1622FX调音台的实际情况，介绍调音台的功能和使用。

声艺FX-16调音台面板说明第一部分输入频道一、背板1、DIR1(DIRECT OUTPUT直接输出)：可接磁带录音机或者效果处理器。

2、MIC(MIC Input麦克风输入)：可接麦克风、话筒等一切稳定或不稳定的音源设备。

3、LINE(LINE Input线性输入)：一般接音源稳定的设备，如CD机、磁带机等；但也可以用来接音源不稳定的设备，如话筒，必须保证音源线足够短。

4、INS(INSERT POINT断点插入插口，也称又出又进插口)，这个插座一般用于将一个信号处理设备直接插入调音台的某个输入或者输出通道，对该通道的音频信号行进更精细的处理二、单声道通道1、GAIN(增益，放大量)使用该按钮可以调节此通道送往MIX（混音器）的声音大小，注意太高了有尖叫，太低了听不清。

2、100Hz (100Hz HI-Pass Filter)：按下此按钮可以减轻话筒的轰隆声或尖叫声。

3、HF=High Frepuency高频段：按下此按钮可以减轻嘶嘶声或者过度的丝丝声MF=Mid Frepuency中频道：中频段包含了几乎所有的口头发音的频段，在使用是请非常仔细的听，举个例子可以用放大或者减小话筒的声音。

LF=Low Frepuency低频段：此按钮用来减低嗡嗡、隆隆声或者提高模糊的声音。

注意：平时一般不用上述旋钮，请把旋钮旋在中间。

4、AUX1、2、3（Aux Sends）：辅助送出，一般用于输出信号供信号处理设备进行处理，或输出舞台监听信号：每个通道都有一个独立的辅助输出（接口在背板），此输出独立于MIX.AUX1通常用于PRE-FADE(推子前)，POST EQ(均衡器后)。

AUX2、3通常用于POSR-FADE(推子后)，POST EQ(均衡器后)。

当按下PRE按钮后AUX2也可以用于PRE-FADE(推子前)，POST EQ(均衡器后)。

5、FX6、PAN(声像调节)，将输入信号（立体声）分配到左路通道与右路通道之间任意位置。
