MP3 CD operation
If MP3 or audio CD files are stored in the
root directory itself, the root directory also
counts as a folder. COMAND will then
display the root directory name as a folder
name.
Permissible MP3 formats
COMAND supports the MPEG1
AudioLayer3 format.Permissible bit and scan rates
Fixed and variable bit rates up to
320 kbps
Scan rates from 24 kHz - 48 kHzThe music tracks that you can create for
play back in MP3 mode are generally
copyright-protected under applicable in-
ternational and national laws.
In many countries, the reproduction of
copyrighted material is not permitted,
even if only for personal use, without the

Please check the current copyright laws
for your country and comply with them.
These restrictions do not apply for exam-

Tips on creating MP3 tracks
i
In everyday speech, this format has
been replaced by the designation
“MP3”.
i
It is recommended to use MP3 tracks
with a bit rate of128 kbps or higher and
with a scan rate of 44.1 kHz or higher.
Lower rates may impair quality. This is
particularly true if the sound function
LOGIC7 Surround has been activated.
