*6 Available for MPEG4 AAC-LC and not available for DRM.
*7 Not available for CD-ROM.
*8 Convert to 44.1 kHz.
*9 Available for I2S, EIAJ, S/PDIF format.
*10 Writing speed to the memory (USB memory, SD memory
card) of the encoding data depends on the response speed
of the memory greatly. Examine the memory which a
connection is presumed fully, and limit the encoding format
specifications of the set because real time encoding can't
be realized when a writing response speed is slow.
