    The DJM-850 combines future-proof technology with the DJ's favourite features. Plug and Play, primed and ready with preconfigured, studio-quality effects accessible at the touch of a button, the mixer offers endless creative possibilities and an unrivaled DJing experience.

    Beat Colour Effect is an industry first. Sidechaining adds a new layer of control. The Beat Effect 'listens' to the audio input of each channel and connects the changes in volume to other parameters making it easy to blend in new sounds and effects.

    The integrated 4-stereo-channel sound card makes set up incredibly simple, with connection to PCs and laptops requiring just one cable.


    Built-in 4-stereo-channel sound card

    • Integrated high-performance sound card and simultaneous input and output ensures there is no deterioration of sound quality.
    • 3 sampling rates enables music recording, production and DJing.
    • Connect to a PC or laptop with one USB cable and start mixing stored music immediately.
    • Make the most of scratch control thanks to the compatibility with the timecode feature on Digital Vinyl Systems, such as Traktor.
    • The utility tool launches as soon as the DJM-850 is connected to a computer, allowing you to configure the mixer, sound card and audio routing according to personal preferences.

    Beat Colour Effect

    • The power of 'sidechaining' adds a new element to the Colour Effects.
    • Beat button adds another dimension of control when you apply the Colour Effects. Beat Colour Effect 'listens' to the audio input of each channel and directly connects the rhythmical changes in volume: resonance for Filter and Crush, beat repeat for Cutterand ducking volume for the Noise Effect

    Improved Beat Effects with new FX Boost

    • 13 enhanced Beat Effects along with Reverb and Spiral Effect,
    • Up Echo produces a more controllable mix (exclusive to the DJM-850).
    • FX Boost function allows the Level/Depth knob to work more proactively than a standard Wet/Dry Control.

    EQ isolator on each channel

    • Each channel has a 3-band equalizer (+6 dB to -26 dB) or 3-band isolator (+6 dB to -26 dB) with a range from -26 kill to complete kill.

    High-quality sound and familiar, industry-standard layout

    • Pristine sound reproduction with reduced noise interference is guaranteed thanks to top-of-the-range components.
    • A user-friendly layout for ultimate familiarity.

    Built for DJs who love to play

    • The internal parts of the high-performance faders are nestled well out of harm's way, so drink spillages aren't a disaster.
    • P-Lock Fader Caps prevent faders from slipping off accidentally during rough use.
    • Fully MIDI assignable, the DJM-850 also serves as a MIDI controller.
    • The USB port is conveniently located on top of the mixer so you can easily switch between connectable devices.
    • The mixer automatically reverts to standby mode if not used for a set period of time.

  • Variety of Advanced Effects
    The DJM-850 follows Pioneer´s traditional mixer layout, featuring a variety of advanced sound effects that provide DJs with virtually limitless possibilities when mixing their music. Pioneer includes a new BEAT COLOR FX function which changes effects by linking the input sound from each channel.

  • BEAT COLOR FX: The SOUND COLOR FX offers four types of effects (Filter, Crush, Noise and Gate) that can be linked to the input sound of each channel.
    SOUND COLOR FX: Users can quickly change between the new BEAT COLOR FX and SOUND COLOR FX to suit each tune for further remixing and sound capabilities. With the industry´s first(*3) BEAT COLOR FX activated, users can manipulate the SOUND COLOR FX in new creative ways to the beat of the music.
    BEAT EFFECT:The BEAT EFFECT function presents 13 different types of effects (Delay, Echo, Up Echo , Spiral Reverb, Trans, Filter, Flanger, Phaser, Robot, Slip Roll, Roll and Reverse Roll) that can be combined to produce up to 100 other original effects.

  • High sound quality
  • MIDI Signal - Operation information of the mixer´s knobs and buttons can be transmitted as a MIDI signal for a "Full Ensemble MIDI" function to control other connected devices.
  • Switching 3 - Band EQ/Isolator - Each channel of the mixer is equipped with a switchable 3-band EQ (+6dB to -26dB) and 3-band isolator (+6dB to -8dB)
  • High Performance Channel Faders - The slide mechanism supports the fader knobs with two metal shafts for both durability and smooth operation.
  • Furthermore, the new mechanism´s design minimizes the negative effects of moisture or dust particles on the mixer´s performance.
  • P-LOCK Fader Cap - Keeps the fader channel and crossfader knobs (caps) locked, preventing them from physically slipping off during heavy use.
  • Scratch Control - Scratch Control is possible by using the time code disk attached to DJ software supporting DVS (Digital Vinyl System) from CDJ players and vinyl turntables.
  • Auto Standby - Automatically senses inactive operation and the presence of input signals, switching to standby mode when inputs are not detected for a long period of time.
