Alpine KD-A815, KD-R810 manual Playing a CD-R or CD-RW

Playing a CD-R or CD-RW

•Use only “finalized” CD-Rs or CD-RWs.

•This unit can only play back files of the same type as those detected first if a disc includes both audio CD (CD-DA) files and MP3/WMA files.

•This unit can play back multi-session discs; however, unclosed sessions will be skipped while playing.

•Some CD-Rs or CD-RWs may not play back on this unit because of their disc characteristics, or for the following reasons:

–Discs are dirty or scratched.

–Moisture condensation has occurred on the lens inside the unit.

–The pickup lens inside the unit is dirty.

–The files on the CD-R/CD-RW are written using the “Packet Write” method.

–There are improper recording conditions (missing data, etc.) or media conditions (stained, scratched, warped, etc.).

•CD-RWs may require a longer readout time since the reflectance of CD-RWs is lower than that of regular CDs.

•Do not use the following CD-Rs or CD-RWs:

–Discs with stickers, labels, or a protective seal stuck to the surface.

–Discs on which labels can be directly printed by an ink jet printer.

Using these discs under high temperature or high humidity may cause malfunctions or damage to the unit.

Playing an MP3/WMA disc

•This unit can play back MP3/WMA files with the extension code <.mp3> or <.wma> (regardless of the letter case—upper/lower).

•This unit can show the names of albums, artists (performer), and Tag (Version 1.0, 1.1, 2.2, 2.3, or 2.4) for MP3 files and show WMA Tag.

•This unit can display only one-byte characters. No other characters can be correctly displayed.

•This unit can play back MP3/WMA files meeting the conditions below:

–Bit rate of MP3/WMA: 5 kbps — 320 kbps

–Sampling frequency of MP3:

32 kHz, 44.1 kHz, 48 kHz (for MPEG-1)

16 kHz, 22.05 kHz, 24 kHz (for MPEG-2)

–Sampling frequency of WMA: 8 kHz — 48 kHz

•The maximum number of characters for file/ folder names is 25 characters (including <.mp3>, <.wma>); 128 characters for MP3/ WMA Tag.

•This unit can recognize a total of 20 000 files and 2 000 folders (999 files per folder).

•This unit can play back files recorded in VBR (variable bit rate).

Files recorded in VBR have a discrepancy in the elapsed time display, and do not show the actual elapsed time. In particular, this difference becomes noticeable after performing the search function.

•This unit cannot play back the following files:

–MP3 files encoded in MP3i and MP3 PRO format.

–MP3 files encoded in an inappropriate format.

–MP3 files encoded with Layer 1/2.

–WMA files encoded in lossless, professional, and voice format.

–WMA files which are not based upon Windows Media® Audio.

–WMA files copy-protected with DRM.

–Files which have data such as AIFF, ATRAC3, etc.

•The search function works but search speed is not constant.
