话筒的技术指标是录音师选择、使用该话筒的重要依据。只有明白它的真实含义,才会合理地处置话筒与声源距离、掌握其声压与电压的转换关系、并把话筒所在的声场的声压级准确地换算成调音台输入端的电平,从而准确选定调音台的输入增益,以得到最高信噪比、最低失真的信号。
Microphone technical indicators is the choice of recording engineer, an important basis for the use of the microphone. Only understand the true meaning of it, will be reasonable to deal with the distance between the microphone and the sound source to master the relationship between the sound pressure and voltage conversion, and the microphone where the sound pressure level is accurately converted into mixer input level, Thus accurately select the console input gain, in order to get the highest signal to noise ratio, the lowest distortion of the signal.
