Evolution of the DJ Mixer Crossfader

Origination The DJ mixer crossfader was originally developed as a control for implementing smooth fades from one program source to another, but where did the idea come from? Fading between two independent sources was first accomplished by DJs using two rotary knobs. They would maintain constant acoustic energy (equal loudness) in the room while carefully fading from one program source to another. Some expertise was required to accomplish this effect accurately and consistently. It became obvious that if a way could be found to fade from one source to another with a single control, the task would be much easier and repeatable for the less experienced.
