 Just as an audio mixing console allows for changes in equalizer levels, dynamics, and balance, an A/V mixer allows variations in hue, color saturation, brightness, sharpness, and other "TV-type" settings.They also allow for various types of transitions between video clips, such as fades, blends, and wipes.A/V mixers are nothing new to the recording and performance industry, but they are more often found in production rooms of television stations or editing suites of movie studios and are a new feature of live turntablist performances.
