有一些剧院扩声系统，要求采用左、中、右路扩声，于是在一些工程设计中就利用了MONO通道代替中央C声道。这种使用的方法有可能存在一些问题，下面仅从声像电位器的电平分配来谈谈MONO的合成信号的内容。声像移位电位器(Panoramic Potentiometer，缩写为Panpot或PAN）简称声像 There are some theater sound reinforcement systems that require left, center and right-hand sound reinforcement so MONO channels are used instead of the central C channel in some engineering designs. This method of using may have some problems, the following only from the sound level potentiometer level to talk about MONO’s synthetic signal content. Panoramic Potentiometer (Panoramic Potentiometer, abbreviated Panpot or PAN) referred to as audio and video
