Formatting Media

The 664 uses the FAT32 file system for CF cards and SD cards under 32 GB in capacity. SD cards with

a capacity greater than 32GB are formatted with the exFAT file system. FAT32 and exFAT are compat-

ible with all major operating systems. Before recording to CF or SD media, cards must be formatted.

To format cards in the 664:

1. Press the Menu button to enter the Setup Menu.
2. Turn the Headphone Encoder to highlight FILE STORAGE, then press the Headphone Encod-

er to enter the FILE STORAGE section.

3. Turn the Headphone Encoder to highlight Erase/Format CF or Erase/Format SD, then Press

the Headphone Encoder to begin the formatting process.

The exFAT file system is not compatible with Windows XP or Mac OS X 10.6.4 or lower.

Time Code

The 664 holds accurate time code for up two hours between battery changes using its internal, Li-Ion

time code battery. After two hours without power, the 664 reverts to a slightly less-precise time-of-

day crystal to maintain the date/time of the unit. This time code battery is charged whenever the 664

is powered up.

If the time-of-day clock is reset during the production day or if the time code mode is changed from

24 hour run to another mode and back, the time code value will change. You must re-jam all time

code devices to ensure proper synchronization.

File-based recorders place a time code and frame rate stamp in the BEXT and iXML chunks of an

AES31 (Broadcast WAV) file. During playback, the 664 generates SMPTE time code from this number

and extrapolates it based on the time code frame rate.

All files generated by the 664 have time code numbers that begin on the 0 frame (or 02 in DF modes)

and end on the 0 frame such that a file’s duration is always an integer number of seconds long. If

necessary, pre-roll and post-roll is dynamically applied to accomplish this. This simplifies synchroni-

zation in post-production.

Sound Devices Wave Agent Beta for Mac OS and Windows computers allows users to add or edit Begin-
ning Time Code Stamps.

See Wave Agent for more details.

The time code value and frame rate of the 664 are displayed on the Main Screen.
