Multisession CDs

For multisession CDs, the content of the first session determines how COMAND will process the CD. COMAND plays only one session and gives priority to the audio CD session.

If possible, use COMAND to play only CDs which have been written in one session.

File structure of a data carrier

When you create a disc with compressed music files, the tracks can be organized in folders. A folder may also contain subfolders.

A disc can contain a maximum of 255 folders.

Each folder can contain a maximum of 255 tracks and 255 subfolders.

The disc may contain no more than eight directory levels. Files beyond the eighth level will not be recognized by the system.

Track and file names

When you create a disc with compressed music files, you can assign names to the tracks and folders.

COMAND uses these names accordingly for the display. Folders which contain data other than MP3 or WMA tracks are not displayed by COMAND.

If MP3 or WMA files are stored in the root directory itself, the root directory will also be treated as a folder. COMAND will then show the name of the root directory as the folder name.

You must observe the following when assigning track names:
Х track names must have at least 1 character.
Х track names must have the extension "mp3" or "wma".
Х there must be a full stop between the track name and the extension.

Example of a correct track name:

"Track1.mp3".

Permissible formats COMAND does not support ID3 tags.

Х Microsoft Windows Media Audio V2, V7, V8 and V9 (WMA)

Permissible bit and sampling rates

COMAND supports MP3 files of the following types:
Х fixed and variable bit rates from 32 kbit/s to 320 kbit/s
Х sampling rates of 8 kHz to 48 kHz

COMAND supports WMA files of the following types:
Х fixed bit rates from 5 kbit/s to 384 kbit/s
Х sampling rates of 8 kHz to 48 kHz

COMAND does not support WMA files of the following types:
Х DRM (Digital Rights Management) encrypted files

128 kbit/s and a sampling rate of at least Only use tracks with a bit rate of at least 128 kbit/s and a sampling rate of at least 44.1 kHz. Lower rates can cause a noticeable deterioration in quality. This is especially the case if you have activated a surround sound function.

Notes on copyright

MP3 or WMA tracks that you create or play back are generally subject to copyright protection in accordance with the applicable international and national regulations.

In many countries, reproductions, even for private use, are not permitted without the prior consent of the copyright holder.

Make sure that you know about the applicable copyright regulations and that you comply with these.

If you own these rights yourself, e.g. for your own compositions and recordings, or if the copyright holder has granted you permission, these restrictions do not apply.

Notes on CDs/DVDs

Discs with copy protection are not compatible with the audio CD standard and therefore may not be able to be played by COMAND.

There may be playback problems when playing copied discs. There is a wide range of data carriers, disc-writing software and writers available. This variety means that there is no guarantee that the system will be able to play discs that you have copied yourself.

There may be playback problems if you play CDs that you have copied yourself with a storage capacity of more than 700 MB. CDs of this type do not conform to the currently applicable standards.

does not contain any music and COMAND On many DVD audio discs, the last track does not contain any music and COMAND then switches to the next disc. This is normal system behavior and does not mean that there is a malfunction.

Do not affix stickers or labels to the discs.
They could peel off and damage the drive.
The drive is designed to hold discs which comply with the EN 60908 standard.
Therefore, you can only use discs with a maximum thickness of 1.3 mm.

If you insert thicker discs, e.g. those that contain data on both sides (DVD on one side and audio data on the other), they cannot be ejected and can damage the drive.

Do not use discs with a diameter of 8 cm, even with an adapter. Only use round discs with a diameter of 12 cm.
