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 MK3 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, and using a separate power supply has no impact on the output level or LED brightness (as opposed to the MK2).
Nieuw in versie 2.2.4.
Veranderd in versie 2.3: Unbind Master knob from Mixxx’s Main Gain, because it controls the hardware volume.
Mixxx Sound Hardware Preferences
Master output: channels 1-2
Headphone output: channels 3-4
