Sound comes out of my headphones or speakers incorrectly.

There are three things to consider: settings, operation and connection.

Please check each in the following order:

1) Confirm the audio output destination setting

Open [Audio] in the rekordbox Preferences and check that the [audio] and [output channel] are selected correctly.

For details, refer to [Checking audio settings] in [Starting the system] in the Quick Start Guide.

*If you can’t select the correct choice because it isn’t displayed or an error has occurred, etc., refer to [Troubleshooting > "I can't set [AUDIO] in the rekordbox Preferences correctly."].

2) Check the volume level operation

1. Play a track.
2. Set the TRIM knob to the center (12 o’clock).
3. Slide the channel fader to the top.
4. Slide the crossfader to the center.
5. Turn the MASTER LEVEL knob to 2 o'clock.

If the MASTER LEVEL indicator lights up more than half way, there’s no problem in the settings and operation.

If you don’t hear any sound from the headphones at this point, check the following:

6. Turn the HEADPHONES MIXING knob to the center.
7. Turn the HEADPHONES LEVEL knob all the way to the left.
8. Press the MASTER CUE button.
9. Turn the HEADPHONES LEVEL knob slowly to the right.

3) Check the connection of speakers and headphones

For details, refer to [Connections] in [Operation] in the Quick Start Guide.

Even if you’ve already connected them, disconnect and reconnect them to make sure they’re properly connected.
