Disc jockeys use a disco mixer to alternate between connected audio components, such as two turntables, CD players or a combination of equipment. The volume on one device can be lowered with the mixer to fade out a song while another track cues up on a different device. This creates a seamless flow of music for a professional, polished sound. To produce any serious volume for a party, the disco mixer must be connected with an amplifier hooked up to stereo loudspeakers. Standard audio cables are needed for the connection between mixer and amp.
