2.10 - Posted October 27, 2014


  • Metadata Screen - When recording audio files this new feature allows quick access to editing Scene, Notes, Take, and Circle status of Previous, Current, and Next WAV recordings. Press AUDIO + MENU or Ctrl + M from an attached keyboard to enter the Metadata Screen. Turn Select encoder to scroll vertically and REW and FF buttons to move horizontally. Press Select Encoder to make selections. Scrolling beyond the Notes field will access your predefined phrase list defined by the new Phrase List Manager.
  • PIXNet Clips Tab Metadata Entry and File Details - This provides the same Medadata functionality as described above, but from a Web Browser via PIXNet. From the Clips tab, click on the gear icon to edit Next Take’s Scene, Take, and Notes. Edit Medadata for previous takes by clicking on the pencil icon of the take; this includes Scene, Take, Notes, and Circle status. This window also displays file details including Start Timecode stamp, Timecode Frames Per Second, User Bits, Duration, Codec, Audio
  • Phrase List - New menu item Menu>File Storage>Phrase List Manager allows a user to create a list of commonly used phrases that can used when updating the Notes field of recorded WAV files. The Phrase List is accessed in the File List>File Info window or from the new Metadata screen.
  • Sound Reports - This new feature creates CSV files based on WAV file metadata. The Sound Report header information is managed in a new Menu option Menu>File Storage>Sound Report Info. To create a Sound Report, navigate to the File List and highlight the desired Reel folder in which the Sound Report is going to be generated, press and hold the encoder (or press right arrow from a keyboard) to enter the Folder Options menu, select Create Sound Report.
    Button shortcut AUDIO + FILES or pressing Ctrl+P on an attached USB Keyboard will create a Sound Report on the current folder for all applicable drives.
  • User Bits Format - In previous versions of firmware, end users could customize the user bits with a four-field format, delineated by colons, such as UU:UU:UU:UU, where U represented a user-definable value. Often, the first three fields in the format would be manually reset daily using two-digit numerical values for the date, such as MM:DD:YY:UU. A new menu option in this version of firmware lets the user configure the unit to automatically populate the first three fields with values derived from the system’s date.
  • Next Take Notes - Users can now enter notes for the next upcoming audio recording. Notes added to the Next Take’s Notes field will only be applied to the Next recording. The following Take’s Notes field is cleared. Next Take Notes can be entered from the File List or from the new Metadata Screen.
  • Daily Folder Option - A new Setup Menu option Menu>FileStorage>Reel Format allows the user to select Custom (default) or Daily. The Custom option works as it has previously where the Reel can be edited with any alphanumeric value. Daily will automatically generate a value derived from the System Date. The Reel folder is named with the following format YYMMDD.
  • MADI Equalizer Option - New Setup Menu option Menu>Audio>MADI Equalizer. In previous firmware revisions the Equalizer was always applied. Some MADI BNC sources with lower voltage-levels or long-cable runs would result in undesired noise. In these cases turn the MADI Equalizer off and the noise will be eliminated.
  • Reel-Scene-Take_Track Name File Name Format - This version of firmware has a new file name format option called Reel-Scene-Take_Track Name. This option only applies when recording WAV mono files, and if selected, the files will be given names in the following format: <Reel>-<Scene>-<Take>_<Track #Track Name>. For example, if Reel=141001, Scene=101A, Take=001, Track=01, and the Track 1 Name=Boom, then the file’s name would be 141001-101A-001_01Boom.WAV.


  • All PIXNet tabs, except Clips, remain open when going into record.
  • The File Info screen uses a numerical spinner for editing the Take information instead of an on- screen, pop-up keyboard.
  • Options for the Circled status is now Yes or No instead of True or False.
  • While recording, track names can be edited from the Audio screen or from PIXNet.
  • User bits are now entered in hex format instead of decimal values.
  • Reverting to a previous used scene name will now only recall the next take if the previous scene was recorded into the current Reel folder.


  • The 970 is now more forgiving when mounting media with corruption. In some cases, depending on the level of corruption, the PIX would show drives as "No Fmt". A common cause of this sort of corruption was termination of the data connection during a write cycle when the drive was connected to a computer. Drives with this sort of corruption will now mount correctly but the corrupted file(s) may not playback correctly or the 250/260/270/970 may report them as corrupted.
  • WAV Mono playback stopping prematurely.
  • Reverting to a previously used Scene Name wouldn’t correctly increment the Take number when using Reel-Scene-Take filename format.
  • Audio meter drawing issue where meters would freeze or display with gaps
  • Audio Screen Gain and Delay value navigation was backwards when adjusting with attached USB Keyboard.
  • Notes added to WAV files can now be deleted.
  • PIXNet now displays a message when the connection to the PIX/970 Unit is terminated.
  • PIXNet Gain Sliders now work correctly with computer’s keyboard arrow keys.
  • PIXNet now properly displays Scene Increment changes when viewing File Storage Tab and Scene Increment is performed on the unit.
  • Reverting to a previously used scene number would set take number incorrectly if the last take of the scene was Circled.
  • Inconsistent pop up qwerty keyboard cursor method.
  • Dante sources continue to display as / if the Audio Screen was displayed prior to network configuration.
  • File List File Info screen can now be escaped with the left arrow of an attached keyboard.
  • Notes containing the following characters inside the parenthesis (< > ‘ “ &) were stored incorrectly.
  • Pressing Play when the loaded file is no longer available will now produce a pop up "File doesn't exist. Please select another one." This occurs when the loaded playback file has been deleted, drive was removed, or the file was renamed from a computer.
  • Various improvements and system enhancements for stability and usability.

2.00 - Posted 2014


  • All files are now recorded using a temporary, and highly recoverable, Sound Devices format (.SDA extension). After each recording, files are “finalized”. Finalized files are standard .WAV files. If a drive is unintentionally removed prior to finalization or any time during recording, files can be recovered by reinserting the drive in the 970. The unit will immediately finalize any detected .SDA files. If .SDA files are present on a drive but a Sound Devices recorder is not available, a Mac and Windows software utility is available (FileSafe™) to finalize files and convert them to .WAV.
  • Grouped units indicate how many units are connected to the assigned group. The number of total units is displayed inside parentheses after the Group number.
  • New menu item Menu>Network>Grouping>Push Settings to Group. When selected, 970 unit settings are propagated to all units in the assigned group. This is useful for ensuring all units in an assigned group are set up in the same configuration.
  • New menu option Menu>Network>Grouping>Sync Audio Screen Settings. When this is enabled all Audio Screen settings (track arm, input source, track name, gain, and delay) are applied to all units in the group. This is useful when grouped units are used for redundant recording.
  • Changes to metadata now apply to all connected drives.
  • When reverting to a previously used Scene Name, the Take automatically updates to the next chronological number based on previous recordings.


  • Removed restriction that would prevent the drive name to be used in the file name.
  • Keyboard shortcut for adding and deleting cue markers has changed. Use Ctrl+Q to add marker, use Shift+Ctrl+Q to delete marker.
  • Multi-file Take Edit Window can now be accessed via the Right Arrow key from an attached USB Keyboard.
  • Non-alphanumeric characters are blocked from use in 970 Name, DRIVE, REEL and SCENE.


  • Fixed - unacceptable level of noise on tracks 13-64 when recording 16-bit monophonic audio.
  • Fixed - unexpectedly high distortion as SDI, MADI or Dante audio input levels get close to the 0dBFS digital clipping point.
  • In Audio Mode the Pre-roll buffer will now reset when the sync source changes to prevent improperly sampled audio from being recorded.
  • The approved HGST Travelstar 7K1000, 1TB 2.5 HDD now mounts without delay.
  • Correction to drive formatting - drives larger than 2 TB would format to an arbitrary size. The 970 does not address more than than 2 TB, drives larger than 2 TB format to 2 TB.
  • Addressed a rare lockup when displaying eight audio meters per page.
  • Overall improvement in speed and reliability when grouping units.
  • The RS-422 remote protocol now supports the full stop command during REWIND and FAST FORWARD.
  • Cue Markers can now be added.
  • Cue Markers are now visible during recording.
  • After formatting or removing a drive, accessing any information remaining on the Clips Tab of PIXNet could result in a lock up.
  • Leading or trailing spaces in Reel names would make the folders invisible to Mac OS.
  • Static IP addresses over an Ethernet switch would sometimes prevent reliable connection with PIXNet.
  • Editing metadata during record that altered the file name could result in Unknown Errors and system lock ups.
  • Numerous PIXNet fixes and improvements.
  • Numerous system improvements and optimizations.

1.0 - Initial Release - Posted April 25, 2014

Please read and follow the steps below carefully. You may want to print them before upgrading firmware.

Sound Devices recommends backing up any existing data that may reside on the recorder. While no data on the storage is changed during the update process, it is best practice to back up the unit. It is also highly recommended to save the current device settings since a firmware update can result in settings changing to factory default.

Prepare to Update

  1. Download the firmware.zip file.
    Note: Some web browsers (most notably, Safari) will open certain files automatically while downloading them. Doing so has caused corruption with archive files including .zip files. Sound Devices recommends to either use a browser that does not do this, or to disable the feature before downloading.
  2. From the zip archive, extract the .prg file.
  3. Copy the .prg file to the root level of an SSD in a PIX-CADDY, CF memory card or HDD. The card or SSD must be formatted as an exFAT volume. (The storage medium should be formatted by PIX/970.)
  4. Power the recorder from external DC. Do not perform the update with an unstable power source.
  5. Insert the SSD , CF card or HDD with the .prg file.
  6. Power on the recorder.
  7. Once booted, push the MENU button to open the Main Menu. Turn the Control knob to highlight System, and then press the Control knob to select it.
  8. Turn the Control knob to highlight Update Software, and then press the Control Knob to select it.
  9. Once a prg has been selected, you will need to reconfirm that the file selected is the correct one. Select Yes to proceed with the firmware update or select No to exit the Software Update. The unit will take a few minutes to update the firmware, indicating its progress. When the update is finished, the unit will present a dialog indicating it will shut down. Accept this dialog to complete the update process.
  10. A dialog will appear asking: "Are you sure?" Make sure Yes is highlighted, then push in the Control knob to initiate the update. The unit will take a few minutes to update the firmware, indicating its progress. When the update is finished, the unit will present a dialog indicating it will shut down. Accept this dialog to complete the update process.
  11. Review settings after updating.

Note: Should problems occur during the update process, then PIX Loader can be used to update the unit.

Applying Update Using PIX Loader Software

  1. If you haven't previously done so, Download the PIX Loader utility for Windows. Otherwise skip to step 2.
    1. Extract the PIX_Loader_1.0_ Install.exe from the downloaded .zip file.
    2. Double-click the installer to begin the installation process. A UAC (User Account Control) dialog might appear asking your permission to allow the installer to run. Allow it.
    3. The Install Shield wizard will guide you through selecting an install location and actually installing the Pix Loader utility. When finished, the PIX Loader utility will be located in the Windows Start Menu.
  2. Turn the unit off.
  3. Using a USB standard A to standard B cable, attach the standard B plug to the USB jack on the rear of the recorder and attach the standard A plug to a working standard A jack on the computer.
  4. There is a small hole on the rear of the recorder which provides access to a recessed button that can be pressed with a thin tool (such as a toothpick or paperclip). The hole is located in the center of the 4 BNC connectors (Timecode and Sync I/O).
    1. If the recorder is configured to power up when external DC power is connected, the cable must be plugged in while the recessed button on the rear panel is held down.
    2. If the recorder is configured to power up by pressing AUDIO + Control knob on the front panel, this button combination must be pressed while the recessed button on the rear panel is held down.
  5. As soon as the Stop button on the front panel illuminates, the recessed button on the rear panel can be released. The recorder is now ready to receive a firmware update from the PIX Loader utility on the host computer.
  6. Open the PIX Loader software.
  7. Press the Browse button and locate the .prg file. Highlight the file and press Open.
  8. Press the Program button to begin the update. Do not remove any cables or close the PIX Loader utility until this process is complete.
  9. When the utility is finished, unplug the USB cable from the recorder and remove the power. The firmware is now updated.
  10. Review settings after updating.
