Approved Media – 6 Series

Sound Devices extensively tests removable recording media with the 633, 664, and 688.

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 6-Series mixer-recorder.

Tested cards:

Sound Devices’ own brand of approved media cards – the SAM-364SD, SAM-128SD, and SAM-32CF – have been optimized and extensively tested to ensure fast and flawless performance when used with the 6-Series of mixer/recorders.

This table contains media approved/tested by Sound Devices, but is no longer readily available for online purchase.

* Note 1: Sound Devices has worked directly with Delkin to identify an intermittent Media I/O issue with newer Delkin CF 500x and CF 700x cards. Delkin has confirmed that a recent change to these two cards is most likely responsible for the errors. Cards containing KZ in the serial number are susceptible to this issue and should not be used. Cards containing VB in the serial number will function correctly and are approved. Deklin CF 1000x and 1050x cards do not experience this issue and may continue to be used.
