RCA connector
The types of inputs that can be plugged into a mixer depend on the intended purpose of the mixer. A mixer intended for a live venue or a recording studio typically has a range of input jacks, such as XLR connectors for microphones and the outputs from DI boxes, and 1/4" jacks for line level sources. A DJ mixer typically has RCA connector inputs for pre-recorded music being played back on turntables or CD players, and a single mic input.
