ALPINE CDE-103BT 68-14470Z98-A (EN)
Supported playback sampling rates and bit rates
MP3
WMA
AAC
This device may not play back correctly depending on sampling 
rates.
ID3 tags/WMA tags
This device supports ID3 tag v1 and v2, and WMA tag.
If tag data is in an MP3/WMA/AAC file, this device can display 
the title (track title), artist name, and album name ID3 tag/WMA 
tag data.
This device can only display single-byte alphanumeric 
characters (up to 30 for ID3 tags and up to 15 for WMA tags) 
and the underscore. For non-supported characters, “NO 
SUPPORT” is displayed.
If information contains characters other than ID3 tag information, 
the audio file may not be played back.
The tag information may not be correctly displayed, depending 
on the contents.
Producing MP3/WMA/AAC discs
MP3/WMA/AAC files are prepared, then written to a CD-R or 
CD-RW using CD-R writing software. A disc can hold up to 510 
files/folders (including Root Folders), and the maximum number 
of folders is 255.
Playback may not be performed if a disc exceeds the limitations 
described above.
Media supported
The media that this device can play back are CD-ROMs, CD-Rs, 
and CD-RWs.
Corresponding File Systems
This device supports discs formatted with ISO9660 Level 1 or 
Level 2.
This device also can play back discs in Joliet, Romeo, etc., and 
other standards that conform to ISO9660. However, sometimes 
the file names, folder names, etc., are not displayed correctly.
Formats supported
This device supports CD-ROM XA, Mixed Mode CD, Enhanced 
CD (CD-Extra) and Multi-Session.
This device cannot correctly play back discs recorded with 
Track At Once or packet writing.
Order of files
Files are played back in the order that the writing software writes 
them to the disc. Therefore, the playback order may not be what 
is expected. Verify the writing order in the software’s 
documentation. The playback order of the folders and files is as 
follows.
* The folder No./ folder Name will not be displayed if no file is 
contained in the folder.
Bit rate
This is the “sound” compression rate specified for encoding. The 
higher the bit rate, the higher the sound quality, but also the larger 
the files.
Sampling rate
This value shows how many times per second the data is sampled 
(recorded). For example, music CDs use a sampling rate of 44.1 kHz, 
so the sound is sampled (recorded) 44,100 times per second. The 
higher the sampling rate, the higher the sound quality, but also the 
larger the volume of data.
Encoding
Converting music CDs, WAVE (AIFF) files, and other sound files into 
the specified audio compression format.
Tag
Song information such as track titles, artist names, album names, 
etc., written into MP3/WMA/AAC files.
Root folder
The root folder (or root directory) is found at the top of the file 
system. The root folder contains all folders and files. It is created 
automatically for all burned discs.
Sampling rates: 48 kHz, 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz, 
16 kHz, 12 kHz, 11.025 kHz, 8 kHz
Bit rates:
8 - 320 kbps
Sampling rates: 48 kHz, 44.1 kHz, 32 kHz
Bit rates:
48 - 192 kbps
Sampling rates:  48 kHz, 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz, 
16 kHz, 12 kHz, 11.025 kHz, 8 kHz
Bit rates: 
16 - 320 kbps
Under the ISO9660 standard, there are some restrictions to 
remember.
The maximum nested folder depth is 8 (including the root 
directory). The number of characters for a folder/file name is 
limited.
Valid characters for folder/file names are letters A-Z (all caps), 
numbers 0-9, and ‘_’ (underscore).
