Battle mixer
A battle mixer is a compact two-channel mixer built around a fast, replaceable crossfader, with curve and reverse controls to hand. Everything else is stripped back to keep the fader area clear.
In practice
A battle mixer is defined by what it leaves out. Everything removed was in the way of one hand.
What you are buying is layout: a short throw between the fader and the platters, controls that do not sit where a wrist needs to be, and a body narrow enough that two decks in battle position actually reach. A reverse switch is near-universal and worth having. An effects section is not — the units fitted to these boxes are usually their weakest part, and a mixer bought for one hand movement should spend its cost on that movement.

Where these come from: Battle-mixer design conventions — established format characteristics, not catalog figures. For what we can measure, see the control that defines the feel.
Why it matters
The format is defined by what it leaves out. No four channels, no elaborate effects section, often no more EQ than you need — because the design goal is a fader you can move thousands of times an hour with nothing in the way of your hand.
The replaceable fader is the part that made the format last. A crossfader is a consumable under scratching, so battle mixers standardised a cutout that accepts a new one, which is why a twenty-year-old mixer can still feel current with a modern magnetic fader dropped in.
Frequently asked
What makes a mixer a battle mixer?+
Two channels, a compact layout that keeps the fader area clear, and a fast replaceable crossfader with curve and reverse controls within reach. It is a shape defined by one hand movement.
Can I use a battle mixer in a club?+
You can, and people do, but a club booth expects four channels for the microphone, the aux and a guest deck. Check with the venue before assuming yours can replace theirs.
Do battle mixers need effects?+
Not really. The onboard units are usually the weakest part of the box, and a mixer bought for one hand movement should spend its cost on that movement.

Crossfader curve
Crossfader curve sets how quickly the sound arrives as the fader leaves its end stop. A sharp curve is fully open within a few millimetres; a smooth curve spreads the change across the whole travel.
Magnetic fader
A magnetic fader senses position with a magnet rather than a wiper touching a conductive track. Nothing physically rubs, so the abrasion that eventually degrades every conventional one never begins.
Hamster crossfader
Hamster is a crossfader wired in reverse, so the left deck lives on the right side of the fader. Scratch DJs run it because it puts the cut on the pull rather than the push.
Battle position
Battle position turns the turntables ninety degrees so the tonearms sit at the back rather than the right, and the pitch faders face you. It puts the record surface and the crossfader in one continuous working area.
