This article explains how to set up your Native Instruments audio interface as the standard audio output device for your computer.
Defining your Audio Interface as System Output
- Make sure your Native Instruments audio interface is connected and recognized.
- Click on the Apple symbol on the top left corner of your computer screen and choose System Preferences.
- Open the Sound menu and select the Output tab.
- Select the entry with the name of your audio interface in the Select a device for sound output menu box. In the example below, we are defining the Traktor Audio 10, which is currently connected to the system.
Now your Mac operating system will output its system audio via a default stereo output channel of your NI audio interface.
Note: When you select an audio device other than Built-in in the Output tab, the volume bar on the top menu of your Mac is greyed-out and you cannot adjust the volume with the volume keys on your computer keyboard (F11 and F12), as indicated by the message The selected device has no output controls.
You can route specific output channels of your audio interface to stream the system audio signal, as explained below.
- Open a Finder window and go to Applications > Utilities > Audio MIDI Setup
- Make sure the Audio window is enabled by selecting Window > Show Audio Devices (OS X 10.9 or lower: Window > Show Audio Window) from the menu bar.
- In the Audio Devices menu, select the name of your soundcard on the left column and then click on the Output tab. Finally, click on Configure Speakers...
In the speaker setup menu you can route the system audio output to an individual channel pair (left and right) of your NI audio interface. The configuration menu will vary depending on the model of your audio interface.
- Click on the drop-down field below Left front and Right front to select the left and right output channels for your system output. In the below example, we are selecting Main Left and Main Right for the TRAKTOR AUDIO 10 audio interface.
- Click Apply and then Done to save the output routing configuration.
Headphone Output Routing
Typically you may wish to output the Mac system audio directly onto your headphones connected to the dedicated monitor output on your NI audio interface. The list below shows which channels are used by the headphone output of your NI audio interface card. Select these channels in the Configure Speakers... menu as describe in the previous steps in order to listen to the system output signal through your headphones:
- Output 3 / 4 of the MASCHINE MK3
- Output 1 / 2 of the TRAKTOR AUDIO 6 / 10 (shares the same output as MAIN 1 / 2).
- Output 1/ 2 or 3 / 4 of the KOMPLETE AUDIO 6 (if you set the headphone switch to 1 / 2, the master output is routed to the headphone output - no additional settings required).
- Output 3 / 4 of the TRAKTOR KONTROL D2 / S8 / S5 / S4 / S2 / Z2 / Z1.
- Output 7 / 8 of the AUDIO 8 DJ.
- Output 3 / 4 of the AUDIO 4 DJ.
- Output 1 / 2 or 3 / 4 of the AUDIO 2 DJ / TRAKTOR AUDIO 2 (depends on the system output settings - if 1 / 2 is selected as main output, headphones have to be set to 3 / 4 and vice versa).
- Any output of the AUDIO KONTROL 1 (if you set the headphone switch to 1 / 2, the master output is routed to the headphone output - no additional settings required).
