DJ: CDJ Troubleshooting

Check that the speakers are powered on: look for the power light, and check the switch at both the back of the speaker and the wall socket.

On the DJM, set all top channel dials to LINE for USB stick and A or B for laptop (whichever one you've plugged your USB cable into).

Set BALANCE and MASTER VOL to the middle position.

Leeds only: channels need to be set to Digital at the top of the mixer.

Make sure the BALANCE knob is set to the middle position.

Unplug the power cable from the CDJ. Turn the CDJ off, then plug the power cable back in and turn the CDJ back on. This is usually due to the power cable not being fully in.

This is because the USB was not prepared through Rekordbox, or the preparation failed. You'll need to prepare your USB again with a laptop. See how to format and export tracks to a USB drive for full steps.

Hold press the Auto Cue button down until "A CUE" (in red) appears on the screen. The CDJ will now stop cueing older tracks and load normal cues instead.

Make sure the jog mode button is displaying Vinyl and not CDJ.

Make sure you're on Vinyl jog mode, as skipping is a feature of CDJ jog mode.

Still not working? Try a CDJ reset.

Make sure the left-hand side switch is not set to REV. Flip the switch up to FWD.

Check Auto Cue is enabled. Make sure the CDJ is not in reverse mode, and that you're not in CD mode.

If needed, remove any USB drives and hard reset: switch the CDJ off at the back, hold down the USB Stop button, the Disc Eject button, and the power button together until you see a message that settings have been restored to factory defaults. Let go of all three, then switch the unit off and on again.

Change the jogwheel mode on the right-hand side of the CDJ to Vinyl mode.

This happens when beat sync was used on a deck and then turned off, leaving the slider in the wrong position. Move the slider all the way up, then all the way down, to reset the tempo sync.

Usually the CDJ is struggling to analyse the tracks, or needs a hard reset. Re-export your tracks through Rekordbox and try a reset.

CDJ 2000 NXS2: you need 3 USB cables and a USB hub. Without all 3 cables, connection isn't possible. For a full setup guide, see connecting your laptop to a CDJ 2000 NXS2.

Possible format or size issue. USB drives must be formatted to FAT32. See how to format and export tracks to a USB drive for full instructions.

Generally caused by a fault with the USB/SD card slot or the Ethernet link port, or by a corrupt or incorrectly formatted track. Try re-uploading tracks or gently wiggling the USB drive.

Relates to a formatting issue: a corrupt audio file, unsupported characters in the file name, or a stale table of contents. Format your USB key and re-export from Rekordbox. See how to format and export tracks to a USB drive.

Still an issue? Turn off the CDJ, unplug the power cable, plug it back in, and turn it on again.

Press the CD eject button. Once a USB or CD is reinserted, the CDJ should show and play tracks as normal.

A CPU-level fault. A factory reset will not fix this — contact support directly for assistance.
