In order to achieve a reasonable level of sound quality, discs recorded with a bit rate of at least 128 kbps are recommended. 001.mp3 002.wma Folder 1 003.mp3 Folder 2 004.mp3 005.wma Folder 3 006.mp3 The play order of the USB memory with the structure shown above is as follows: 001.mp3 002.wma ...006.mp3 PLAYABLE BIT RATES MP3 files for USB memory: MPEG 1 AUDIO LAYER 3 - 32 to 320 kbps MPEG 2 AUDIO LAYER 3 - 8 to 160 kbps WMA files for USB memory: Ver. 9 (9.1/9.2) CBR - 48 to 320 kbps (VBR*) *: Variable Bit Rate M3u playlists are not compatible with the audio player. MP3i (MP3 interactive) and MP3PRO formats are not compatible with the audio player. The player is compatible with VBR (Variable Bit Rate). When playing back files recorded as VBR (Variable Bit Rate) files, the play time will not be correctly displayed if the fastforward or reverse operations are used. It is not possible to check folders that do not include MP3/WMA files. MP3/WMA files in folders up to 8 levels deep can be played. However, the start of playback may be delayed when using USB memory containing numerous levels of folders. For this reason, we recommend creating USB memory with no more than two levels of folders. USB memory: It is possible to play up to 3000 folders, 255 files per folder or 9999 files in the device. The order changes depending on the personal computer and MP3/WMA encoding software you use. 216
