To use the Pioneer DJ DJM-850, DJM-900NXS or DJM-900NXS2 mixer with DVS control and Serato DJ, you will first need to purchase a Serato DJ licence and a DVS Expansion Pack licence (these two products have been bundled together as the Club Kit).
You can purchase the Club Kit HERE
Once you have purchased the Club Kit (or individual licences separately) enable CD/Vinyl Control in the DVS Expansion Packs section of the SETUP screen under the Expansion Packs tab. Follow the steps below to get DVS control working with your Pioneer DJ DJM-850, DJM-900NXS or DJM-900NXS2 mixer:
1. Install Drivers
Connect the DJM-850, DJM-900NXS or DJM-900NXS2 to your computer and open the latest version of Serato DJ. You should see an "Install Driver" dialogue box appear in the right hand side-panel. Click "Install Driver" and follow the installer prompts. If you don't have the hardware with you right now you can still download the driver from the manufacturers website. Go to PioneerDJ.com here. After you have installed the latest drivers it is recommended you restart your computer.
2. Select Input source
Once your turntables or CDJs are connected to DJM-850, DJM-900NXS or DJM-900NXS2, open the SETUP screen and under the AUDIO tab click the SETUP INPUTS button. This will open the device driver window panel and let you choose which kind of input source you have connected. Depending on what kind of input you have connected (Turntables/CDJs) you will need to make sure this is set accordingly.
NOTE: If you do not set the mixer's input accordingly, DVS control will not work. Please make sure you have set the correct inputs and outputs in the SETUP INPUTS driver panel if you are having issues.
3. Select Primary Decks
Also in the AUDIO tab of the SETUP screen, you will need to select your Primary Decks.
Choosing Channel 1 and 2 will allow you to have a traditional 1-2-3-4 channel configuration. Choosing Channel 2 and 3 will allow you to have a 3-1-2-4 configuration (from left to right across the mixer).
Select which deck configuration you are using with the mixer and change if necessary. If you notice you are getting signal from your control tone but on the wrong deck, you might need to double-check your Primary Decks in the SETUP screen or the physical inputs on the back of the mixer.
You are now set up to use your mixer with Serato DJ and DVS control using the REL or ABS control modes. Refer to the Serato DJ software manual for more information on Control Modes.
