Horizontal fader that blends or cuts between two mixer channels.
The crossfader is a horizontal fader on a DJ mixer that controls the balance between two channels: fully left gives Channel 1 only, fully right gives Channel 2 only, and center passes both equally. Its curve is adjustable, ranging from a smooth blend to a near-instant cut favored in scratch and hip-hop DJing.
Why it matters
The crossfader is central to cuts, scratching, and battle-style mixing. A sharp crossfader curve lets a DJ cut a channel in and out with fast wrist movements; a smooth curve suits slow blends between tracks.
