The recording times shown above are estimates. They might differ depending on the SD card in use.

The recording times shown above are not continuous recording times, but rather they are the total possible recording times for the SD card.

Compared to 2-track recording, the recording times for 4-track and 6-track recording will be 1/2 and 1/3, respectively.

NOTE

If a file size exceeds 4 GB when recording, the unit will automatically continue recording in a new file (file incrementation).

When DUAL FORMAT is on, skips in the audio could occur in the MP3 format files when recording files are switched.
