Additional Information
! The sound quality of WMA files generally
becomes better with an increased bit rate.
This unit can play recordings with bit rates
from 48 kbps to 320 kbps (CBR) or from 48
kbps to 384 kbps (VBR), but in order to be
able to enjoy sound of a certain quality, we
recommend using discs recorded with a
higher bit rate.
! This unit doesnt support the following for-
mats.
Windows Media Audio 9 Professional
(5.1ch)
Windows Media Audio 9 Lossless

WAV additional information
! This unit plays back WAV files encoded in
Linear PCM (LPCM) format or MS ADPCM
format.
! You can only play back WAV files in the fre-
quencies 16, 22.05, 24, 32, 44.1 and 48 kHz
(LPCM), or 22.05 and 44.1 kHz (MS
ADPCM). The sampling frequency shown
in the display may be rounded.
! The sound quality of WAV files generally be-
comes better with a larger number of quan-
tization bits. This unit can play recordings
with 8 and 16 (LPCM) or 4 (MS ADPCM)
quantization bits, but in order to be able to
enjoy sound of a certain quality, we recom-
mend using discs recorded with the larger
number of quantization bits.

Notes
! This unit assigns folder numbers. The user
can not assign folder numbers.
! It is not possible to check folders that do not
include MP3/WMA/WAV files. (These folders
will be skipped without displaying the folder
number.)
! MP3/WMA/WAV files in up to 8 tiers of folders
can be played back. However, there is a delay
in the start of playback on discs with numer-
ous tiers. For this reason we recommend
creating discs with no more than 2 tiers.
! It is possible to play back up to 99 folders on
one disc.
