M 20X Digital Mixer Reference Guide

FAT32 is the only supported file format on M series digital mixers and is also the safest cross-platform (Mac / PC) format.
Avoid FAT16 formatting, as random problems in audio file playback have been noticed.
Please notice that the minimum supported device size for audio recording is 4 GB (mainly due to variations if formatting
results for smaller sized devices).
For STEREO mode, USB 3.0 compatible storage devices are recommended, as these guarantee higher data throughput.
Furthermore, consistent and error-free results have been obtained with premium, good-quality USB pens. Several
lower-quality devices can cause random errors due to their lower data transfer performance. We have found that on
several USB devices it is recommended to have at least 50% free space on the USB key; beyond this percentage, most
USB keys show significant fragmentation and in this case, glitches can appear in recorded files.
For
MULTITRACK
mode, SDHC and SDXC formats are supported.
Due to filesystem limitations, the internal recorder can generate a file with maximum size of 4 GB, corresponding to
about 4 hours of continuous stereo recording or 20 minutes of continuous 20 channels recording. If this limit is
exceeded, the recorder closes the current file and creates another file with no audio gap, without interrupting the
recording process. Thus, the complete recording can be reconstructed on audio editing software.
In case you need to reformat a USB pen or SD Card for audio recording, the M 20 digital mixer provides Format tools
between the System utilities.
