Audio Mixer Circuits

  

An audio mixer circuit, also called a mixing console, is an electronic circuit for combining, and modifying audio signals. In the process, the source signals level, frequency content, dynamics, and panoramic position are manipulated and effects such as reverb may be added. Audio mixers can be analog or digital type. Digital mixing consoles use Digital Signal Processing concepts and analog mixers are usually based on op-amps electronic circuits.

Audio mixing is practiced for music, film, television and live sound. The process is generally carried out by a mixing engineer operating a mixing console or digital audio workstation. The input audio signals could be anything from microphone inputs, to an audio output of a cd player, to an output of a PC sound card or any other type of analog audio sources.

The basic mixer will be able to combine those signals from different signal sources, change the volumes of each input channel, as well as the overall volume of the mixer output, or the equalization, bass, midrange, treble on each audio channel.
