Operation
4.1
Overview
4.1.1 Only standard CDs can be recorded to the flash memory. Discs
containing MP3 songs can not be recorded to the flash memory,
but they can be played.
4.1.2 Recording speed is 4X faster than playback speed. A four (4)
minute song will record in about one (1) minute. A 60 minute CD
will record in about 15 minutes.
4.1.3 There are two recording bitrates (32 kbps and 64 kbps). The higher
bitrate is better quality but requires twice the amount of memory.
You can record some songs at one bitrate and other songs at a
different bitrate. The bitrate can be changed in the setup menus.
The Record Quality of previously recorded songs can not be
changed. The song must be deleted and re-recorded to change the
Record Quality of a song.
4.1.4 The flash memory can store about 450 minutes of music at 32 kbps
bitrate or about 225 minutes at 64 kbps bitrate.
4.1.5 Songs can not be played from the CD while the CD is recording,
however a work around is described in Section 4.5.
4.1.6 CD songs are stored in a unique directory labeled DIR_XX. When
songs from a new CD are recorded they will be stored in the next
sequential directory. Songs from the same CD will always be
recorded in the same directory.
4.1.7 CD song tracks are labeled TrackXX.cda. Songs stored in flash
memory are labeled TrackXX.aac. The song number (XX) when
recorded will remain the same as it is on the CD. So if Track05.cda
is recorded from the CD, it will be labeled Track05.aac in the flash
memory.
