688 Firmware v4.00

688 with Wingman app on iPhone

688 gets a Wingman

The 688 now supports remote control via the Wingman, a free iOS wireless interface app at the App Store.

WM-Connect dongle

WM-Connect Required

Integration with Wingman requires WM-Connect, a Bluetooth Smart USB accessory by Sound Devices.

Sound Devices 688 firmware - (v4.00) provides a firmware update for the 688 field production mixer, which includes support for the Wingman wireless interface app and WM-Connect accessory. This firmware update also includes several performance enhancements.

It is highly recommended that users update to the latest version of firmware available as soon as possible.

Download the available 688 User Guide. It is up-to-date with all relevant features and functionality changes provided in the latest released versions of firmware.

Known Issues

The list below are the published known issues for the latest 688 Firmware.

  • The CL-12 does not always initialize when connecting to the 688 if the CL-12's DC Boost Input is connected.
    Workaround:
    When disconnecting the CL-12 from the 688: Remove the DC Boost Input micro USB cable before disconnecting the CL-12/688 USB A to USB B cable. When connecting the CL-12 to the 688: Connect the CL-12/688 USB A to USB B cable before connecting the DC Boost Input micro USB cable.
  • Rare issue where the system clock gets set to an invalid date. This can cause the daily folder to be incorrectly named and therefore the files get stored in the wrong folder. As of V2.00+, if the 688 detects an invalid date, it will display the following message: “System date error detected. Please reset time and date.”

1.00 - initial release

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

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

    From the zip archive, extract the file within named 688_4.00.prg file. Copy this .prg file to the root level of an approved SD or CF memory card. Do not place the file in any folder. Do not place the 688_4.00.zip file on the SD or CF card. The card must be formatted in the 688.
  2. Apply Update to 688.
  3. Power the 688 from external DC. Do not perform the update with low batteries or unstable power sources.
  4. Power down the 688 if it is already powered up.
  5. Insert the SD or CF card with the .prg file.
  6. Power on the 688.
  7. Navigate to Setup Menu option SYSTEM > Update Firmware and follow the on-screen instructions.
  8. When the update is complete the 688 will power cycle itself. The version number 688_4.00 will be displayed briefly on the splash screen while booting up. A message box appears "Firmware updated successfully Version:688_4.00". Press "OK". Please note any changes or additions to the Setup Menu (if applicable).
