What Is a Microphone Amplifier?

The microphone amplifier is referred to as "telephone amplifier", which is a device that amplifies the signal input from the microphone. The full name of the preamp is: "pre-amplifier" for microphones. Many high-end preamps now use "electron tubes" to amplify. In fact, preamplifier is not just a simple function of "power amplification", many also include parametric equalization, compressor, phantom power, etc., especially compressor and parametric equalizer. Many preamplifiers also have a high acquisition rate A / D analog-to-digital converter, which converts the microphone's analog signals into digital audio signals and outputs digital audio formats such as AES.
