Sound Devices 664 Field Mixer Firmware 2.12

Fixed:

- Timecode LED doesn't flash when unit is off even though timecode is being maintained.

- Timecode backup is not timing out after two hours while powered off. This is causing the timecode battery to fully drain which would result in timecode not holding for 2 hours on the next shut down.

- Track R and Track X2, when linked to Track L and X1 respectively, are not returning to their attenuated level after Tone is toggled on and off.

Known Issues:

- If you try to arm paired LR or X1/X2 tracks using the CL-12 LR, X1/X2 pots, arming does not operate on the pairs. They must be armed independently from the CL-12 or directly from the mixer. Arming pairs from the mixer works fine.

- 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.

Prepare to Update:

- Download the 664 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 664.

- Apply Update to 664.

- Power the 664 from external DC. Do not perform the update with low batteries or unstable power sources.

- Power down the 664 if it is already powered up.

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

- Power on the 664.

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

- When the update is complete the 664 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).
