Yes. When DDJ-SX2 and the computer are connected and a track is played in iTunes, the sound is input to the DDJ-SX2's channel 1. It cannot be input to other channels. Also, files containing DRM data cannot be played.

If sound is not input when the above operation is performed, do the following.

Windows 7

Display the [Run] dialog box from the [Start Menu], enter [mmsys.cpl], and then click [OK]. The [Sound] window opens. Select "PIONEER DDJ-SX2" on the [Playback] tab of the [Sound] window.

*This cannot be used simultaneously with the ASIO driver.

Windows 8 and 8.1

Select [Run] from the [Apps view], enter [mmsys.cpl], and then click [OK]. The [Sound] window opens. Select "PIONEER DDJ-SX2" on the [Playback] tab of the [Sound] window.

*This cannot be used simultaneously with the ASIO driver.

Mac OS

In "Select a device for sound output" on the [Output] tab in [Sound] of [System Preferences], select "PIONEER DDJ-SX2" from the sound devices. DDJ-SX2’s input channel can be changed by selecting "PIONEER DDJ-SX2" in [Audio MIDI Setup] of [Applications] > [Utilities] and then using the [Configure Speakers] dialog box.
