舞台专业音响的调音与配接

Tuning and Matching Concerning the Stage

提出了舞台要使专业音响达到良好的效果应注意的几个问题，介绍了对各种差异很大的音源和信号进行调音、混合及频率均衡的方法，分析了扬声器与扩音机之间不匹配的影响，计算并提供了扬声器与扩音机之间不同配接方式下的阻抗匹配有关数据．

In this paper,we put forward several key questions conceming achieving good effects in the stage——specially used acoustics operation.We also introduce some good methods to tuning and mix the tone creater and singals which have great differences between each other and how to balance the audio frequency,analyzing the effection caused by the immatching existing between the loud speaker and audio amplifier,and calculate and give the datas of impedance matching under the condition of the immatching existing between loudspeaker and audio amplifier.
