Step 1. Connections
Connect the MC-3000 to a USB port of your computer using the provided USB cable. Connect a pair of amplified speakers to the Master Output at the rear panel of the unit and your Headphones at the front socket.
Step 2. Drivers
Windows : No driver is required. You can download and install the Denon ASIO drivers from https://www.denondj.com/downloads#legacy, but due to driver stability issues, the WASAPI Windows driver will be used instead of the Denon ASIO driver in VirtualDJ Audio Setup
Mac OSX : No drivers is required to be installed for Mac OSX computers.
Update the firmware of the unit to the latest version from http://denondj.com/products/view/mc3000
Step 3. VirtualDJ
Install VirtualDJ 8 from http://www.virtualdj.com/download/index.html (in case you have not done already)
Start VirtualDJ and login with your Account credentials. A Pro Infinity, Pro Subscription or Plus MC-3000 Controller License is required.
Find a detailed installation procedure at http://www.virtualdj.com/manuals/virtualdj8/quickstart.html
A detection window will appear when the unit is first connected with VirtualDJ, verifying proper connection
Click on the Use Soundcard button in order VirtualDJ to apply the pre-defined audio configuration using the built-in sound-card of the unit. Speakers need to be connected to the rear panel of the unit in this case.
Click to OK
The unit is now ready to operate with VirtualDJ.
