Audio mixers, basically, mix sounds of different volumes, and outputs to a master channel by passing effects through various channels. They are used by orchestras, live bands etc. While DJ mixers are supposed to do roles, which the audio mixers simply can’t handle. The DJ mixers have to match the beat of 2 or more audio channels, assist you in deploying your mix with creativity, apply filters and effects to your audio channels, and make your overall set sound great!
