Is the power cord properly connected? Plug the power cord into an AC outlet and turn on the power button.
If, however, the power does not turn on, normal operation can sometimes be restored by unplugging the power cord, waiting at least 1 minute, and then plugging the power cord back in. If the symptom persists, unplug the power cord and request repairs.

-Is the [LEVEL/DEPTH] control set to an appropriate position? Turn the [LEVEL/DEPTH] control clockwise or counterclockwise.
-Set the channel that adds the effects properly by using the [1,2,MIC,CF1,CF2,MASTER] selector switch.

Is the [COLOR] control set to an appropriate position? Turn the [COLOR] control clockwise or counterclockwise.

-For some tracks, it may not be possible to measure the tempo.

-JOG does not function for external output (PHONO/LINE input).
-The built-in JOG is electromagnetic and therefore it may not responsive to touches with gloves.
-Scratch does not respond if the JOG MODE is set to VINYL OFF. Set the JOG MODE to VINYL ON.

Crossfader does not operate when Scratch is set to [THRU]. Set the crossfader to settings other than [THRU].

The last memory of TIME/REMAIN, AUTO CUE, MASTER TEMPO, TEMPO RANGE, QUANTIZE and various UTILITY settings starts 5 seconds after the settings are done. There is no last memory if the device is turned on within 5 seconds after the settings are done.
After changing settings, wait at least 5 seconds before turning the power off.

The loading time differs according to the USB memory device's performance.
Also, some time may be required for loading during USB recording.

When you slowly move your palm over the jog dial, it may respond even though you don't touch it, depending on the detection sensitivity setting.
Keep your hand away from the jog dial except to touch it.

The sync operation may not be working for one of the reasons below.
-Was the track loaded in the folder browsing mode? The sync operation can only be performed if the track is loaded in the library browsing mode.
-The sync operation is not possible if slave deck's BPM is less than the master deck's BPM, even if the tempo is +16%. In this case, the message "OUT OF RANGE" is displayed on the LCD.

When the sync function is turned on for the deck that is not the master deck, that deck's tempo slider is disabled.

To prevent sudden changes in the tempo, if the tempo (BPM) being played on the master deck does not match the tempo corresponding to the position of the tempo slider, the unit is designed so that the tempo does not change until the tempo slider is set to the position corresponding to the currently playing tempo.

The BPM value corresponding to the tempo slider's position is displayed on the LCD's playing speed display. Operate the tempo slider to match this with the value displayed in the square frame directly below this. After this is done, the tempo slider can once again be operated.

To keep the tempo from changing suddenly directly after the sync function is turned off, the unit is designed so that the tempo of audio output does not change when the tempo slider is operated until the tempo at the position of the tempo slider matches the tempo of audio output.

The BPM value corresponding to the tempo slider's position is displayed on the LCD's playing speed display. Operate the tempo slider to match this with the value displayed in the square frame directly below this. After this is done, the tempo slider can once again be operated.

Set the [MIC LEVEL] control to the proper position.

The way the BPM is processed differs on the XDJ-RX and other devices, so the BPM may be displayed differently. This is not a malfunction.

When the master tempo function is turned on, key control processing is used to keep the key constant, so the sound changes. This change in sound quality is due to the current system's specifications and is to be expected considering product's performance.

1. Format the track by using formats supported by the unit (FAT32, FAT, or HFS+).
2. The Mac OS standard format of GUID partition map is not supported.
3. If a USB device is formatted with a Mac Extended format where 'Case Sensitive' is set, the unit may not recognize the device properly.

It could be one of the two cases below. Check the USB devices (flash memory drives and hard disks) .
1. There is not enough free space on the USB devices.
2. The device is write-protected.

Only the tracks analyzed by using rekordbox are registered in HISTORY. If the analyzed tracks are not registered in HISTORY, following 4 cases are possible.

1. No sufficient space available on the USB device (such as flash memory or hard disk).
2. The USB device is write-protected.
3. The track is loaded for less than 60 seconds. (Once the track is loaded for more than 60 seconds, the track is registered in HISTORY. If track is paused for more than 60 seconds, or any action other than playback is performed on the track for more than 60 seconds, it is registered in HISTORY.)
4. The track is not registered in HISTORY when the track was loaded from the [Folder] and played.

When using near speakers that produce high volumes, such as club speakers, reading of data on the USB hard disk may be hampered by the influence of the acoustic pressure traveling through the space or vibrations traveling through the table.
Generally, such measures as moving the set to a place where it is not affected by acoustic pressure or using vibration damping materials are effective. For detailed information on installing in such environments, contact your hard disk manufacturer's support center.

When the quantize function is on, playback starts from the nearest beat position at the time the button is pressed. If you want the operation to be performed the instant the button is pressed, turn the quantize function off.

When rekordbox (iOS/Android) is running and the telephone or another application is used in the foreground, rekordbox (iOS/Android) processing continues in the background. However, applications running in the background may be suspended or stopped due to iOS or Android operating system control.
If you have used the telephone or another application, quit it promptly and set rekordbox (iOS/Android) back to the foreground.

This may be due to one of the following reasons:

1. The Android smartphone you are using does not support the MTP mode. The smartphone must support the MTP mode in order to connect it by USB cable to the XDJ-RX. For information on whether or not your smartphone supports the MTP mode and how to set it, see the operating instructions of the smartphone
2. Depending on the specifications of the MTP mode of the smartphone you are using, the operation may differ depending on whether or not an SD memory card is inserted. In some cases, it may be possible to connect the smartphone to the XDJ-RX after removing (or inserting) the SD memory card.
3. Depending on the specifications of the MTP mode of the smartphone you are using, there are some terminals on which the “MTP in use” message is displayed continuously in the foreground of the screen of the smartphone while connected by MTP. With such terminals, rekordbox cannot be operated with MTP connections, so such terminals cannot be connected to the XDJ-RX using a USB cable.
4. Depending on the specifications of the MTP mode of the smartphone you are using, MTP connections may only be usable with applications exclusively for Macintosh or Windows. Such terminals cannot be connected to the XDJ-RX using a USB cable.

It is, however, necessary to update the firmware of the XDJ-RX when using rekordbox (Android).
For details, see the link.

In normal mode, the sound is managed by each 0.5 frame (1/150 seconds).
Hence, the PAUSE position deviates when the track is paused while the JOG mode is set to VINYL mode, and is switched to Normal mode.

Set the background LINE/PHONO selector switch properly in accordance with the devices connected to the LINE/PHONO terminal.

When the SLIP mode is ON, the loop is repeated even when the LOOP SLICE is set to 'SINGLE'. Set the SLIP mode to OFF when operating LOOP SLICE at 'SINGLE'.

If audio is not output or you cannot control rekordbox when using Windows, please see here to solve the problems.
