Stanton Djc.4

Compatibility

This controller is a class compliant USB MIDI and audio device, so it can be used without any special drivers on GNU/Linux, Mac OS X, and Windows. However, if you wish to use the ASIO sound API under Windows, please install the latest driver package available from the Product page.

Sound card setup

This controller has a built-in 4 channel sound card, with MASTER output (RCA and balanced 6.3 mm TRS) and HEADPHONE output (6.3 and 3.5mm jack).

Output
Channels	Assign to
1-2	Master
3-4	Headphones
Input
Channels	Assign to
1-2 (Input 1)	Vinyl Control 1 or Aux 1
3-4 (Input 2)	Vinyl Control 2 or Aux 2

Above the Gain knobs are switches to select which input should be sent to the PC. For input 1 this can be Aux (3.5 mm TRS) or Line/Phono 1/2 (RCA) and for input 2 this can be microphone (6.3 mm TRS on front) or Line/Phono 3/4 (RCA).

Input 1 routing

On the rear side is a small switch to select if Input 1 is routed to the PC or directly to the master output (through). It is therefore possible to include the microphone into a recording/stream or to exclude it.

Please refer to the user manual for more details about the audio configuration in Mixxx.

Hardware controls

The Master and Mic Level are hardware controls and interact directly with the integrated sound card and are not mapped to Mixxx.

Please refer to the user manual in order to learn how to set your levels properly when using Mixxx.

The mapping is included in Mixxx 2.2.4 and newer.
