Sound Devices 633 Field Mixer Firmware 4.50

New:

- Auto Mixer

- Dugan Auto Mix

- MixAssist

- Ctrl+T keyboard shortcut to toggle Tone On/Off

Changed:

- High-Pass Filter now returns to last used value when toggled on and off rather than always reset to 150Hz.

- Recording of 192 kHz monophonic wav files is no longer allowed. In previous firmware, recording was not prevented even though it was classed as an unsupported mode. Set to polyphonic when recording 192 kHz.

Fixed:

- Long file names on exFAT formatted media are truncated.

- Factory Option for Scene Name can be overwritten by user if Scene Name is edited during record. This can cause Scene Increment Mode to stop working.

Known Issues:

- Auto-Mute timecode modes output timecode for a few seconds after booting up from a full shutdown.

- 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.

Firmware Installation Instructions:

- 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.

- Download the 633 firmware file.

- From the zip archive, extract the file within. 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 zip file on the SD or CF card. The card must be formatted in the 633.

- Apply Update to 633.

- Power the 633 from external DC. Do not perform the update with low batteries or unstable power sources.

- Power down the 633 if it is already powered up.

- Insert the SD or CF card with the .prg file.

- Power on the 633.

- Navigate to Setup Menu option SYSTEM > Update Firmware and follow the on-screen instructions.

- When the update is complete the 633 will power cycle itself. The version number will be displayed briefly on the splash screen while booting up. A message box appears "Firmware updated successfully Version: XXX". Press "OK". Please note any changes or additions to the Setup Menu (if applicable). Consult the 633 User Guide and Technical Information for details.
