Pioneer's DJM-800,the world's most popular DJ mixer has been dead for some time, so it's no surprise that Pioneer has now announced the new Pioneer DJM--850 DJ Mixer. The DJM-850 comes in two colorsjust like the Pioneer DJM-700, and it has four channels. It is PACKED full of one hundred different effect combinations, for almost endless possibilities. It's likely that the DJM-850 will soon replace the DJM-800 as the standard in the world's top nightclubs.

The DJM-850 is also a great choice in terms of the price, as it retains its predecessor's features, and adds superb effects which are all its own. The DJM-850 also comes with something called the Beat Colour Effect, which is an industry first, using side chaining to add further enhancements to your Colour Effects. The Beat Effect actually ‘listens" to the audio input of every channel and it connects volume alterations to other factors, so enabling DJ's to further enhance the music. Added to this, the DJM-850 has an integrated four-stereo-channel sound card, making the setup very simple. It also connects easily to PCs and laptops via one cable. It's also Traktor Scratch Pro 2 certified, which means you'll be able to use Native Instruments' excellent digital vinyl system without the need for a separate and expensive audio interface. Other new features include a new set of effects, including a Pitch Echo effect, and a beat button for each Colour FX dial that sidechains the track currently playing through a gater effect to produce some stunning sounds. It strangely lacks an Ethernet port, which means you can't connect Pioneer's CDJ-900 and CDJ-2000s to it.

The DJM-850 is being promoted as being a future-proof mixer, with an integrated USB four-channel soundcard, multiple effects units and the overall build quality that's expected from Pioneer's kit. Most interesting are the new options for effects control. When enabled, Beat Color Effects allow a DJ to take the Color Effects found on each channel and apply a beat-synced layer of control on top of the effect using the Beat Effects control unit. Pioneer's explains it best: The Beat Color Effect 'listens' to the audio input of each channel and directly connects the rhythmical changes in volume to another parameter: resonance for Filter and Crush, beat repeat for Cutter and ducking volume for the Noise Effect. The Beat Effects unit has has a new level of control added to it as well, called FX Boost. Designed around the resulting effects possibilities of the DJM-900?s touch strip control, FX boost adds a second layer of control to effects using the Level/Depth knob. Turn the dial to the 12 o'clock mark for a fully wet effect and turn it further to add Pitch Up to Up Echo and a High-Pass Filter to the Reverb.

As far as what you're missing compared to the Pioneer DJM-900 nexus, the 850 is lacking digital inputs and the ethernet Link port for allowing CDJs to access music data via the mixer and Rekordbox. Also, there's still only one USB port, meaning that transitioning between two DJs who want to use the mixer's USB soundcard in a CDJ-free environment (rare as it might be) is a massive pain. Rane has this down with your flagship mixers, and when you spend a good amount of money on a mixer, it seems only logical.

An integrated high performance USB soundcard that enables up to four inputs/outputs(*1) simultaneously with no deterioration in audio fidelity. The soundcard supports three different sampling rates (96kHz/48kHz/44.1kHz) and the ASIO/Core Audio standards that can also be used for music recording and production. The USB port on top of the mixer provides quick connections to use DJ software via laptop. The signal output path from the mixer can be easily modified using its setup utility tool(*2) via a computer.

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 your music. Pioneer has a new BEAT COLOR FX function which changes effects by linking the input sound from each channel.

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.

You 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, you can manipulate the SOUND COLOR FX in new creative ways to the beat of the music.

The BEAT EFFECT function presents 13 different types of effects (Delay, Echo, Up Echo <new>, 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.

The DJM-850 is equipped with additional features that add to the versatility of the mixer:
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 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 -?dB)
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 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.
