Behringer DDM 4000 DJ Mixer

Behringer DDM4000 — 32-bit Power for the Booth

The Behringer DDM4000 is a 32-bit digital DJ mixer that packs a club-grade feature set into a single rack-mountable unit. Five independent channels — four stereo phono/line plus a mono mic — let performers route up to eight signal sources simultaneously. Two patented BPM counters drive automatic synchronization across the sampler, FX engines, and crossfader. This unit suits working DJs who need a hardware centerpiece for mixing, sampling, and effects without a laptop.

What Sets This Mixer Apart in Its Tier

Two independent, BPM-synchronized FX engines each ship with nine editable effects — Bitcrusher, Resonator, Reverb, Flanger, Phaser, Delay, Echo, and Pitch — assignable to different channels at once. The onboard sampler holds two memory slots for samples up to 32 seconds, with beat-controlled loop, real-time pitch control, and reverse playback. A dual-mode Ultracurve crossfader adds frequency-selective crossfading, so bass stays locked on one side while mids and highs swap across the mix.

Five Channels and Programmable EQ — Routing for Any Setup

Channels 1 through 4 are stereo phono/line inputs with toggle switches, so turntables and CDJs share the same mixer. Each channel carries a programmable parametric 3-band EQ with up to 12 dB of boost and a full Kill function for instant frequency cuts. The mono mic channel hosts two XLR inputs, dedicated EQ, a Talk function that ducks the music, and its own FX send.

• Channels: 5 (4 stereo Phono/Line + 1 mono mic) — connect up to 8 sources at once
• Two XLR mic inputs with Gain, EQ, Talk-over, and FX — handles MC duties without crowding the music
• EQ: Programmable parametric 3-band with Kill function — up to 12 dB boost per band

Beat-Synced Sampler and Dual FX Engines — Creative Tools Onboard

Recording a snippet of incoming audio, the integrated sampler loops it without dropping the beat, freeing the DJ to queue the next track. Two freely assignable FX engines run effects in parallel on separate channels, with parameters editable through the front-panel display. Effects can be locked to the song tempo via the dual BPM counters, so echoes and delays stay in phase.

• Sampler Memory: 2 slots, up to 32 seconds each — loop, one-shot, forward, or reverse
• Two assignable, BPM-synced FX engines — 9 effects each including Bitcrusher, Reverb, Flanger, Resonator
• BPM Counters: 2 patented — auto-sync sampler, FX, crossfader, and external drum machines

Ultracurve Crossfader, MIDI, and Studio-Grade I/O

Offering adjustable curve, reverse, tap, and hold functions, the digital Ultracurve crossfader adds automatic BPM-synchronized crossfading for hands-free transitions. Three-band EQ Kill buttons sit on either side of the fader for dramatic frequency cuts mid-mix. Full MIDI controller support maps faders, knobs, and buttons to DJ software, while a digital S/PDIF output captures performances directly to a recorder.

• Crossfader: Digital Ultracurve, dual-mode, frequency-selective — replaceable cartridge
• XLR Master Out, RCA Booth + Rec Out, S/PDIF digital, MIDI DIN — plus 4 stereo Phono/Line inputs
• Dimensions: 320 × 392 × 110 mm, Weight: 4.2 kg — rack-mount brackets included

Who Should Choose This Mixer

The DDM4000 is the right choice for mobile DJs, bedroom producers, and small-club performers who want hardware-grade sampling and effects without flagship pricing. Its MIDI implementation makes it equally useful as a tactile controller for Traktor, Ableton Live, or Virtual DJ. Anyone running a hybrid vinyl-and-digital rig benefits from four stereo phono/line channels that accept up to eight sources at once.

Behringer — German Engineering, Accessible Pricing

Founded in Germany by Uli Behringer, the company built its reputation on the Studio Exciter F and later expanded into mixers such as the Eurodesk MX8000. Through acquisitions of Midas, Klark Teknik, and TC Electronic, Behringer folded high-end audio engineering into its product lines. Released in March 2008, this mixer delivers features found on units costing several times more.
