Native Instruments Traktor Kontrol S2 MK3

The Kontrol S2 MK3 is a two-channel controller with an integrated sound card. It has two integrated stereo outputs (line and 1/8“ / 3.5 mm TRS), headphone outputs (1/8” / 3.5 mm TRS) and microphone inputs (1/4“ / 6.3 mm TRS). The MK2 uses the standard HID protocol to send and receive signals from a computer, so it can work with Mixxx. The Kontrol S2 MK3 can run from USB bus power. Using the separate power supply increases the brightness of the LEDs, which is helpful for using it in daylight, and increases the volume of the headphone output.

Mixxx Sound Hardware Preferences

  • Master output: channels 1-2
  • Headphone output: channels 3-4
