Audio 20 supports the following types of
WMA files:
R fixed bit rates from 5 kbit/s to 384 kbit/s
R sampling rates of 8 kHz to 48 kHz
Audio 20 does notsupport the following types
of WMA files:
R DRM (Digital Rights Management)
encrypted files
R variable bit rate
R WMA Pro
R 5.1 surround sound
i 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 notice-
able deterioration in quality. This is espe-
cially the case if you have activated a sur-
round sound function.
Notes on copyright MP3 or WMA tracks that you create or play
back are generally subject to copyright pro-
tection 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 compact discs i
Discs with copy protection are not com-
patible with the audio CD standard. Con-
sequently, it may not be possible to play
them on the Audio 20 system.
Playback problems may occur when play-
ing copied discs. A wide range of data
media, burning software and burners is
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.
! 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. There-
fore, you can only use discs with a maxi-
mum 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 can-
not 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. Bluetooth Audio
