Crossfader circuit

Requirements for a turntablist crossfader control circuit

• Small off-to-on travel distance - the appropriate channel should be fully muted when the fader is in the zero position, and bring the channel to full volume within the first few millimetres of wiper travel.
• Decay time - when the fader is moved, the appropriate channel should change volume at a rate quickly enough to allow rhythmic cutting, but slowly enough to eliminate any clicks and pops which would be caused by an instantaneous decay
