The microphone amplifier can also be called a special microphone preamplifier, which is similar to a power amplifier and is a device for amplifying audio signals. Most high-end microphone amplifiers on the market use electronic tube amplification, the main purpose is to obtain the beautiful sound of the electronic tube. In fact, with the continuous development of science and technology, the role of microphone amplifiers is not only to amplify power, many products also include functions such as parametric equalization compressors. After understanding the main function of the microphone amplifier, let's take a look at how to use the microphone amplifier.
Dear friends, when using the microphone amplifier, you first need to connect the microphone cable and the microphone amplifier, and adjust the input level of the microphone amplifier through a normal sound test. Take the human voice as an example. When debugging, you can allow the singer to sing normally with the accompaniment and adjust the input screen so that the peak of the sound does not exceed the cut-off level of the device.
Secondly, it is necessary to adjust the compressor of the microphone amplifier. When making adjustments, friends must understand the purpose of using the compressor of the microphone amplifier, not only to compress the dynamics of the sound, but also to make the sound more expressive and fuller. . It is also necessary that the sound cannot be heard by the listener after being compressed. In simple terms, it is a song or an instrument. If you make the listener feel that the sound is compressed after recording, then this It means that the compressor of the microphone amplifier has failed.
The last step is to adjust the dynamic range of the sound. The adjustment method is also very simple. For example, when a singer's voice is the smallest, it may be -60db, and the largest voice may be 0db, which means that the singer's dynamic range is 60db. When the singer is singing, if the voice is lower than -35db, it may be unclear. So we need to adjust the dynamic range of the singer's voice within 35db, so that the recorded singing voice can be heard clearly.
