CX-9_8AU2-EA-09G_Edition1 Page267 Wednesday, July 8 2009 12:8 AM Black plate (267,1) Interior Comfort Audio System l l l l l This unit can play MP3s with sampling frequencies of 16/22.05/24/32/44.1/48 kHz. This unit can play MP3 files that have been recorded in bit rates of 8 kbps to 320 kbps. Nonetheless, to insure enjoyment of music with consistent sound quality, it is recommended to use discs that have been recorded at a bit rate of 128 kbps or more. If a disc has both music data (CD-DA) and MP3 files, playback of the two file types differs depending on how the disc was recorded. Packet written discs cannot be played on this unit. This unit does not play CDs recorded using MP3i (MP3 interactive), MP3 PRO and RIFF MP3 formats. The order of hierarchy for MP3 files and folders during playback or other functions is from shallow to deep. The arrangement and playing order of a recorded disc containing MP3 files is as follows: File number A numerical file number is assigned to each file in a folder in the order of hierarchy from shallow to deep. Folder number A numerical folder number is assigned to each folder in the order of hierarchy from shallow to deep. l l Folder No. : Folder 01 02 04 : Track (File) 3 03 2 05 4 06 5 1 Level1 Level3 Level2 Level4 About folders and files l l Playback may not occur in the above hierarchy depending on the audio unit. l l l NOTE Folders and tracks (files) within the same hierarchy play in the order they were written to the disc depending on the write software. l l The folder order is automatically assigned and this order cannot be optionally set. Any folder without an MP3 file will be ignored. (It will be skipped and the folder number will not be displayed.) MP3 files not conforming to the MP3 format containing both header frames and data frames will be skipped and not played. This unit will play MP3 files that have up to eight levels. However, the more levels a disc has, the longer it will take to initially start playing. It is recommended to record discs with two levels or less. A single disc with up to 512 files can be played and a single folder with up to 255 files can be played. When naming an MP3 file, be sure to add an MP3 file extension (.mp3) after the file name. 6-23 Form No.8AU2-EA-09G
