Allen & Heath Xone:K3 DJ Mixer

Allen & Heath Xone:K3 — A Fully Customisable MIDI Controller for Modern DJs

The Allen & Heath Xone:K3 is a professional MIDI controller designed for DJs, producers, and performers who need hands-on control of their software and hardware setups. Built around 52 physical controls and three fully independent layers, it assigns up to 174 individual MIDI parameters per map — enough headroom for four-deck workflows, stem control, effects chains, and sampler triggering from a single slim unit. Housed in a diecast metal chassis with a steel front panel, this model is engineered for club booths, live stages, and home studios. As a class-compliant USB MIDI device, it works with macOS, Windows, iOS, and Android without drivers.

What Sets the K3 Apart

What makes this controller stand out is its diecast chassis with nutted pots, tactile buttons, and a steel front panel — a build philosophy borrowed directly from the manufacturer's club-grade Xone mixers. The free Xone Controller Editor app unlocks per-control MIDI CC and Note assignment, custom RGB feedback colours, customisable layers, and portable map files. A factory map replicates the original Xone:K2 layout, so existing K-series users can drop this instrument into their rig without rewriting mappings.

Control Surface — Faders, Encoders, Pots, and Buttons

RGB LED feedback on all 30 buttons plus the encoder push-switches gives clear visual confirmation in dim booth lighting.

• Physical controls include 52 total elements, featuring 30 buttons, 12 rotary pots, 6 endless encoders with push-switches, and 4 linear faders.
• Faders: 4 x 60mm linear — smooth full-throw control for volume, crossfade, or any CC-assigned parameter
• Endless encoders with built-in push-switches send relative CC (127/1) messages — ideal for fine scrubbing, nudge, and parameter tweaking without end stops
• Rotary Pots: 12 with 270° rotation — absolute CC (0–127) for EQ, filter sweeps, and gain staging

Connectivity, Power, and MIDI Flexibility

Both USB-C and X:Link (RJ45) ports are present, allowing the unit to act as a standalone USB MIDI controller or to chain into an existing Xone mixer ecosystem.

• USB-C Port: USB 2.0 Full Speed (12 Mbps) — class-compliant MIDI and bus power in a single cable
• Standard CAT5 cables with RJ45 connectors are used for X:Link to transmit both power and MIDI data between compatible mixers.
• Compatible Xone Mixers: Xone:96, PX5, 43C, 23C, K2, and DB series — drop-in integration with the wider ecosystem
• Power Draw: 5V, 450 mA max (2.25 W) — bus-powered via USB or X:Link

Build, Dimensions, and Road-Ready Form Factor

The slim footprint is designed to sit alongside a Xone mixer without crowding the booth.

• Chassis: Diecast metal with steel front panel — nutted pots and tactile switches rated for repeated live use
• Dimensions (unpacked): 49.5 x 135 x 358 mm — slim profile fits neatly beside any Xone mixer
• At just 1.25 kg, this unit slips into a laptop bag or backpack without sacrificing build rigidity

Who the K3 Is Built For

This controller is the right choice for working DJs, hybrid live performers, and producers who want tactile, customisable control over DJ software, DAWs, lighting rigs, or video applications. Modular DJs running Algoriddim djay Pro benefit from a custom factory map that exposes roughly 90–95% of the software's features across three layers — including four-deck control, stem manipulation, effects, and sampler triggering.

Allen & Heath and the Xone:K Series Heritage

The manufacturer has been designing professional mixers and controllers from its Cornwall, England headquarters for decades, and the Xone:K series has long been a reference point for compact MIDI control in the DJ world. This latest version succeeds the K1 and K2 with a larger control count, RGB feedback, and a more rugged chassis.
