Approved Media – MixPre II Series and MixPre Series

Sound Devices extensively tests removable recording media with the MixPre-3 II, MixPre-6 II, MixPre-10 II, and the legacy MixPre-3, MixPre-6, and MixPre-10T audio recorders.

SD Cards

Sound Devices recommends its own brand of SD card – the SAM-64SD and SAM-128SD, listed below – which has been optimized and extensively tested to ensure fast and flawless performance when used with the MixPre Series of recorders. However, many SD, SDHC, and SDXC cards from other reputable manufacturers, like Delkin or SanDisk, that meet or exceed class 10 speeds are acceptable.

For best media performance, Sound Devices recommends occasionally performing a full reformat of an SD card per the “Overwrite Format” method from the SD Association. The Overwrite Format deletes file/directory entries by initializing file system parameters of the card (same as with Quick Format), and erases all data by overwriting the user data area completely. The Overwrite Format takes more time to complete than the Quick Format method. More information can be found on the SD Association’s website. Please note that all files stored on the card will be lost during the formatting process. After using the SD Memory Card Formatter, the card will still need to be formatted in the mixer-recorder.

MicroSD to SD Card adapters are not recommended for use in any MixPre Series audio recorder.
