! The CDJ-900 supports such USB mass storage class USB devices as external hard discs,
portable flash memory drives and digital audio players. External DVD/ CD drives and
other optical disc devices cannot be used.
! When there are many folders or files, some time may be required for loading.
! If multiple partitions are set for the USB device, the device may not be recognized.
 Cautions on using USB devices
! Some USB devices may not operate properly. Please note that Pioneer will
accept no responsibility whatsoever for loss of data recorded on USB devices.
! USB hubs cannot be used.
! USB devices equipped with flash card readers may not operate.
! If a current above the allowable level is detected in the CDJ-900's USB port,
it could happen that a warning message is displayed, the power to the USB
device is cut off and signal transfer is stopped. To restore normal operation,
remove USB devices connected to the player, then press USB STOP. Avoid
reusing the USB device for which the excess current was detected. If normal
operation is not restored after performing the above operation (if signals are
not transferred), try turning off the player's power then turning it back on.
! Depending on the USB device you are using, the desired performance may
not be achieved.
About MP3 files
MP3 files can have a constant bit rate (CBR) or a variable bit rate (VBR). Both
types of files can be played on the CDJ-900, but the search and super fast search
functions are slower with VBR files. If your priority is operability, we recommend
recording MP3 files in CBR.
The CDJ-900 supports MP3 files in the formats shown below.
