Motorized Fader
- Simply a fader attached to some type of motor for the purposes of automation control. Motorized faders are commonly found in mixing boards with automation. These systems work by recording and saving as data the positions and movements of the faders as an engineer mixes. During playback the data is converted to a form that can be used to control movements of a precision motor (servo motor), which will then return the fader to the corresponding positions, providing an automated mix. In some motorized fader systems the audio levels are controlled by VCA's (audio doesn't pass through the fader at all); the fader is only used as a means to control the VCA levels and as a means to display the virtual fader positions as levels are controlled by the automation system.
