Recording mode settings at the time of purchase:
The recording mode for each selector is set to "LPCM" at the time of purchase. The recording mode for each selector can be set
individually ( OI page 28).
If you want to change the recording mode to AAC, please note the following:
Recordings made to this unit are initially recorded in LPCM, and then are converted to AAC. Therefore if you are making
continuous, long recordings, the maximum amount of recordings you can make must fit within the LPCM limits for maximum
possible recording time as described in the chart above. In the event that you are making many recordings, continue recording
after the music data has been converted to AAC format ( OI page 26, How recordings work).
Note
LPCM audio quality does not exceed the audio quality of the original recording.
