Pioneer CDJ-400 Digital Deck


Pioneer seems to have a finger in every pie at the moment and DJ CD decks are no exception.

The Pioneer CDJ-400 is an easy-to-use DJ CD player, providing comprehensive support for MP3 playback via both USB media and CD-ROM. There are cheaper MP3 CD decks out there, but none at this price range currently offer MIDI support. It might be too...

Product Specifications

USB Integration & MP3 PlaybackThe CDJ-400's cosmetic design is simple and compact yet elegant with all of its various controls and features located directly on top of the unit. A USB port found on the face of the player allows DJs to play their MP3 music collection from a wide variety of portable music devices such as thumb drives, MP3 players or external hard drives. With the use of a multi-function selector knob/button and its large, bright, dot-matrix LCD display, locating and accessing of files from these types of music devices as well as MP3 music files on CD and CD-R/RW through the CD slot are done with a turn and press of the knob. DJ Software Compatibility and MIDI Control With more of today's DJs utilizing different DJ software for their performances, the CDJ-400 is also equipped with a PC mode. In this mode, the CDJ-400 is a native controller for software such as Pioneer DJS computer software and Serato Scratch Live. For example, the movement of the pitch slider on the CDJ-400 can control the pitch slider on the computer software and no time code CD is required for audio control. The player can also act as a MIDI controller were you can assign virtually every button on the player to trigger functions of various DJ software programs. World's First Scratch Jog EffectA highlight and an advancement of the CDJ-400 is its scratching capability. In addition to traditional vinyl" mode scratching, Pioneer implemented the World's First Scratch Jog Effect. Three highlighted buttons, each assigned to a special effect, Bubble, Trans and Wah, creates unique scratching sound effects that can be enabled by the DJ on the fly. A hold" button was also added to retain the different effects throughout the session or until its release, which can also be triggered at any point of play. Tempo Control - Four tempo modes, +-6%, +-10%, +-16% and wide, provide additional speed
