MixPre II displays the following error message even when using the ASIO driver with Windows 10 and 11 computers. “The incoming USB Audio is not true 32-bit float. Please use MacOS 10.15 (Catalina) or set output bit depth to integer.” Please ignore this error message.
As productions continue to use more microphones simultaneously, producing a clean mix with intelligible speech can become quite difficult. Automatic mixers can help sound professionals in these multi-microphone applications.
The Scorpio, 888, 833, 633, and 688 offer two automatic mixing algorithms: Sound Devices’ own MixAssist and Dugan Automix, a collaboration between Sound Devices and Dan Dugan Sound Design, Inc.
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.
All MixPre II models and the MixPre-10T supports automatic copying of active projects from its SD card to a USB thumbdrive inserted into its USB-A port. For reliable operation, Sound Devices highly recommends only using approved USB thumbdrives, listed below:
NOTE: Because USB thumbdrives vary massively in performance, others not listed here may work, but their reliability cannot be guaranteed.

* 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.
RICKMANSWORTH, NOVEMBER 12, 2018 — Audio Limited—the UK’s premier wireless manufacturer—announces the release of firmware v2.50 for the A10 Digital Wireless System. Version 2.50 adds User Groups, which enables a user to build a list of frequencies with names, allowing quick and easy tuning of the A10-TX and A10-RX.
Sound professionals can match easy-to-remember names with pre-coordinated frequencies. When User Groups are loaded into the TX and RX, the frequency menus are simplified, showing only the user-selected frequencies. This eliminates tedious scrolling and provides a quick and easy way to set frequencies on location.
“Our customers have been asking us for a user group memory function on the A10 system that allows them to pair preset frequencies with customized names, thus allowing quick setup on the TX and RX and enhancing their workflow,” said Kishore Patel, Managing Director Audio Ltd. Version 2.50 of the Mic2Wav, the Mac OS and Windows software application now allows specific sections of a sound file to be converted based on a timecode range. This can greatly reduce conversion time and file size.
The v2.50 update for the A10-RX, A10-TX, A10-TX Remote app for iOS and Android, and Mic2Wav application for Mac and Windows is available from November 12, 2018. The Sound Devices 688 adds support for the A10 User Groups with firmware v4.54, released the same day. Learn more about these and other features of the A10-Digital Wireless System at www.audioltd.com.
