Pioneer CDJ400 MP3 CD USB Player Controller

Product Information

Tempo resolution is also very good, with steps of 0.02% at ±6% range which is ideal for keeping those long beat mixes in sync. Otherwise the slider moves in steps of 0.05% when set to ±10 or ±16%, and steps of 0.5% when set to WIDE. One function that is missing is a ‘brake’ effect that simulates the slow wind-down and start-up sound on a vinyl turntable, but you can always improvise using the Tempo slider in the WIDE mode. Aimed at aspiring club DJs to use at home, the Pioneer CDJ-400 will play standard audio CDs as well as MP3s off CD-R/RW discs, but not DVDs. It will also play music directly from mass storage USB devices such as USB keys and external hard drives. Of course, like any gadget worth its salt these days, the CDJ-400 works fully with an iPod. Designed for DJs by DJs and drawing inspiration from our industry standard CDJ-1000 series, the CDJ-400 is a flexible, affordable performance player for the aspiring club DJ to use at home.
