How to Connect a Disco Mixer to an Amp

Updated February 21, 2017

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.

Unplug the mixing board and the amplifier from the electricity before connecting or disconnecting any audio cables.

Connect the plugs on one end of the audio cables to the Master Output jacks on the back edge of the mixer. The white plug connects to the left audio output and the red plug connects to the right.

Insert the plugs on the other end of the cables into the Line IN jacks on the amplifier, matching the white plug to the left channel and the red plug to the right.

Restore power to the equipment and adjust the amp volume control to the desired level.


Always disconnect electronic equipment from the electricity when hooking up components with audio cables. This can prevent a power surge from burning out an amp or loudspeaker.
