在文艺演出的扩声系统中,耳机通常是作为监听系统使用。文艺演出开幕之前,音响师要逐一检查乐队各路话筒是否工作正常,有无噪声干扰等现象,还要检查各路话筒通道是否对应着所需要拾音的乐器,都需要在调音上使用监听键(CUE),并通过耳机来监听各路音源信号是否处在正常工作状态。
In the theatrical performances of the sound reinforcement system, the headset is usually used as a monitoring system. Before the opening of the theatrical performance, the sound engineer should check each band’s microphones one by one whether they are working properly or not, whether there is noise interference or not, and also check whether the channels of the microphones correspond to the musical instruments that need to be picked up. All of them need to be monitored on the tuning Key (CUE), and through the headphones to monitor each channel audio signal is in normal working condition.
