Features
This unit is a DJ player carrying over the technology of the Pioneer CDJ series, the world standard for club players. It is not only equipped with a wide range of features for DJ performances supporting a variety of sources, including the PRO DJ LINK, quantize and beat sync functions, it also has a high sound quality, high reliability design and a panel layout providing high operability, thereby offering strong support for all types of DJ performances.
MULTI MEDIA, MULTI FORMAT
In addition to discs (CDs), music files stored on USB devices (flash memory devices or hard disks) and on mobile devices can also be played. The formats of music files that are supported include not only the music CD (CD-DA) and MP3 formats, but also AAC, WAV and AIFF. The included rekordbox (Mac/Windows) music management software can be used to carefully prepare the playlists, cues, loops and beat grids you will need for DJ performances at home, so that you can devote your attention to the DJ performance at the disco/club with ease of mind. This makes for a deejaying cycle smoothly integrating all the steps, from acquiring the music files to the actual DJ performance.
rekordbox (Mac/Windows)
rekordbox is a software program allowing users who have purchased a Pioneer DJ player supportingrekordbox to manage music files to be used for DJ performances.
The included rekordbox music management software can be used for the management (analysis, settings, creation, history storage) of music files on computers. Using music files managed with rekordbox in combination with this unit makes it possible to achieve outstanding DJ performances.
- In these operating instructions, the version of rekordbbox for Mac/Windows is referred to as "rekordbbox (Mac/Windows)". "rekordbbox" is used to indicate the versions of rekordbbox (Mac/Windows) and rekordbbox (iOS/Android) simultaneously, as well as when referring to rekordbbox functions directly.
rekordbox (iOS/Android)
rekindbox (iOS/Android), a smartphone application that can be downloaded free of charge, can be used for the management (analysis, settings, creation, history storage) of music files on mobile devices. Using music files managed with rekindbox (iOS/Android) in combination with this unit makes it possible to achieve outstanding DJ performances.
- In these operating instructions, the version of rekordbox for mobile devices is referred to as "rekordbox (iOS/Android)".
PRO DJ LINK
Functions include "USB Export" using USB devices (flash memory drives and hard discs) and "rekordbox LINK Export" using the computer on whichrekordbox is installed.
USB Export
This function can be used to transfer rekordbox music files and management data using USB devices. This eliminates the need to take your computer to the disco or club.

DISPLAY
This unit is equipped with a large, high-resolution full-color LCD making the information required for DJ performances easy to see.
BROWSE
The combination of the list display of music files and an easy-to-operate rotary selector lets you select tracks without stress. In addition, the display of track artwork lets you find the desired tracks instinctively.
WAVE/WAVE ZOOM
The overall waveform ("WAVE") can be displayed so that you can grasp the overall composition of the track visually. Also, the frequency bands are color-coded, and a zoomable enlarged waveform ("WAVE ZOOM") can be displayed so that the development of the track can be grasped instantaneously.
BEATCOUNTDOWN
The precise number of beats from the currently playing point to saved cue points can be grasped instantaneously.
BEAT SYNC
Based on the GRID information of tracks analyzed with rekordbox, the tempo (BPM) and beat position of tracks playing on this unit can automatically by synchronized with other DJ players connected by PRO DJ LINK. The beat sync function helps you mix tracks and create mixing and effect performances, greatly expanding the range of DJ performances.
QUANTIZE
This unit is equipped with a quantize function that automatically corrects the timing when using such functions as looping, reversing or slip looping, even if you perform operations off-beat, as long as the track has been analyzed with rekordbox. This enables accurate performances without breaking the rhythm of the currently playing track.
SLIP MODE
This unit is equipped with a slip mode function with which playback of the track continues in the background during looping, reversing, scratching or pausing. This enables DJ performances without changing the track's development, even after you finish looping, reversing, scratching or pausing.
BEAT DIVIDE
The beat pattern of the currently playing track can be changed easily with simple button operation. This lets you improvise a wide range of beat arrangements, without breaking the rhythm of the currently playing track.
MY SETTINGS
The settings of this unit's functions can be stored on USB devices or mobile devices and loaded back onto this unit when necessary. It is also possible to make this unit's settings in rekordbox then transfer them directly to this unit. This lets you quickly switch to the settings you have prepared yourself in advance when replacing another DJ in a club.
HIGH SOUND QUALITY
The audio output circuitry uses low-jitter clocks and high-performance Wolfson D/A converters. Furthermore, undesirable digital noise from the audio power supply is blocked, so the original sound is reproduced faithfully to achieve clear, rich club sound with a strong sense of the sound field.
SOUND CARD
This unit is equipped with exclusive interface and MIDI interface for controlling the DJ software of other brands. There is also a built-in sound card, so other equipment can be connected easily.

About the liquid crystal display
- Small black or shining points may appear on the liquid crystal display. This is a phenomenon inherent to liquid crystal displays; this is not a malfunction.
- When using in cold places, the liquid crystal display may be dark for a while after this unit's power is turned on. It will reach the normal brightness after a while.
- When the liquid crystal display is exposed to direct sunlight, the light will reflect off it, making it difficult to see. Block the direct sunlight.

Cautions on use
About condensation
Water droplets (condensation) may form inside the unit (on operating parts and lenses) in the winter, for example, if the unit is moved from a cold place into a warm room or if the temperature in the room in which the unit is installed rises suddenly (through heating, etc.). The unit will not operate properly and will not be playable with condensation inside. Let the unit stand for 1 to 2 hours at room temperature (though this time depends on the conditions of the condensation) without turning on the power. The water droplets will evaporate and the unit will become playable. Condensation can occur in the summer as well if the unit is exposed to the direct wind from an air-conditioner, etc. If this happens, move the unit to a different location.
Cleaning the lens
The player's lens should not become dirty in normal use, but if for some reason it should malfunction due to dust or dirt, consult your nearest Pioneer authorized service center. Although lens cleaners for players are commercially available, we advise against using them since some may damage the lens.
Handling discs
Storing
- Always place discs in their cases and store them vertically, avoiding hot, humid places, places exposed to direct sunlight and extremely cold places.
- Be sure to read the cautions included with the disc.
Cleaning discs
- Discs may not play if there are fingerprints or dust on them. In this case, use a cleaning cloth, etc., to gently wipe the disc from the inside towards the outside. Do not use dirty cleaning cloths.

- Do not use benzene, thinner or other volatile chemicals. Also do not use record spray or antistatic agents.
- For tough dirt, apply some water to a soft cloth, wring out thoroughly, wipe off the dirt, then wipe off the moisture with a dry cloth.
- Do not use damaged (cracked or warped) discs.
- Do not let the signal surface of discs get scratched or dirty.
- Do not place two discs in the disc tray, one on top of the other.
- Do not attach pieces of paper or stickers to discs. Doing so could warp discs, making it impossible to play them. Also note that rental discs often have labels attached to them, and the label's glue may have oozed out. Check that there is no glue around the edges of such labels before using rented discs.


About specially shaped discs
Irregularly shaped discs other than standard 12 cm discs cannot be played on this unit (doing so will lead to damage or accidents). Specially shaped discs (heart-shaped, hexagonal, etc.) cannot be played on this unit. Do not attempt to play such discs, as they could damage the unit.

About condensation on discs
Water droplets (condensation) may form on the surface of discs if they are moved from a cold place (particularly in winter) into a warm room. Discs may not play normally if there is condensation on them. Carefully wipe the water droplets off the surface of the disc before loading it.
