 Most faders are based on the principle of metal brushes, usually brass or stainless-steel, contacting a PCB covered in a carbon track. The carbon track increases in resistance along its length, and this change in resistance can be used to control an audio circuit.
-Early mixer designs actually made the fader a part of the audio signal path, allowing the change in resistance of the wiper to adjust the relative volume level of the output. Later mixers used the fader to generate a control voltage for a [[wikipedia:Voltage Controlled Amplifier|Voltage Controlled Amplifier]], allowing techniques such as filtering and curve adjustment. A more in-depth discussion of the crossfader support circuitry can be found in the [[Crossfader circuit]] section.
