Time Code - Sound Devices 664 User Manual And Technical Information

If the CF card is oriented correctly, it will slide in easily until only a few millimeters are protruding. If the
CF card is oriented incorrectly, it will slide in easily until over 1 cm of the card is still protruding.
Formatting Media
The 664 uses the FAT32 fi le system. FAT32 is compatible with all major operating systems. Before
recording to CF or SD media, cards must be formatt ed. To format cards in the 664:
1. Press the Menu butt on to enter the Setup Menu.
2. Turn the Headphone Encoder to highlight FILE STORAGE, then press the Headphone En-
coder 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 formatt ing process.

Time Code

The 664 holds accurate time code for up two hours between batt ery changes using its internal, Li-Ion
time code batt ery. 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 batt ery 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) fi le. During playback, the 664 generates SMPTE time code from this number
and extrapolates it based on the time code frame rate.
All fi les 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 fi le's duration is always an integer number of seconds long. If
necessary, pre-roll and post-roll is dynamically applied to accomplish this. This simplifi es synchroni-
zation in post-production.
Sound Devices Wave Agent Beta for Mac OS and Windows computers allows users to add or edit Beginning
Time Code Stamps. See Wave Agent for more details.
The time code value and frame rate of the 664 are displayed on the RTN Screen:
