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-350, but the search
and super fast search functions are slower with VBR files. If your prior-
ity is operability, we recommend recording MP3 files in CBR.

 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.
! It may happen that, when a current above the allowable level is
detected in this unit's USB port, the [USB STOP] indicator flashes,
the power supply to the USB device is cut off and communications
with the USB device are interrupted. To restore normal operation,
disconnect the USB device from this unit. Avoid reusing USB
devices for which an excess current has been detected. If normal
operation is not restored (if communications cannot be estab-
lished) after the above procedure is performed, try turning off this
unit's power then turning it back on.
! If multiple partitions are set for the USB device, the device may not
be recognized.
! USB devices equipped with flash card readers may not operate.

About AAC files

! AAC is the abbreviation of "Advanced Audio Coding", a basic
format of audio compression technology used for MPEG-2 and
MPEG-4.
! The file format and extension of AAC data depends on the applica-
tion used to create the data.
! In addition to AAC files with the extension ".m4a" encoded with
iTunes®, files with the extensions ".aac" and ".mp4" can also be
played. Note, however, that copyright-protected AAC files pur-
chased for example at the iTunes Music Store cannot be played.
Also, some files may not be playable, depending on the version of
iTunes used for encoding.
