Recording
The 970 records industry standard Broadcast WAV Files (BWF) on up to 4 storage devices. Each drive
can be configured independently to be available for recording, available for playback (read-only),
shared on the network via Samba, or switched to network sharing after becoming full (Setup Menu
option [File Storage - Drive Record/Network Mode]). ( See “Storage and File Management”, page 39 )
Pressing the Record Button will start recording provided there is at least one audio track armed. Re-
cording will continue until the Stop () button is pressed or until all available drives are full. While
recording:
• The Record Button will illuminate red.
• The Main View text and drives actively recording turn red.
• The Setup Menu is not accessible.
If the 970 is not ready to record when a record command is given, the unit will enter a Record
Pending state. In this state the Record Button will flash red, and the system will automatically enter
record when it becomes ready. A Record Pending state is usually caused by file storage mounting or
response time or Play/Pause.
Record and Stop can also be triggered by other devices ( See “Network Grouping”, page 29 ), via a web
browser ( See “Web Interface - PIXNET”, page 31 ), RS-422 , GPIO, and Timecode. External control of
RS-422 , GPIO, and Timecode is configured in Remote Control. ( See “External Control”, page 31 )
Sound Devices File Format
During recording the 970 writes to a temporary file format. Files are written with the extension
.SDA. When recording is stopped, the file is “finalized” to a standard Broadcast Wave format (.WAV
extension). The Sound Devices file format allows for reliable recovery of content in situations where
power was lost or a drive was removed during recording. Upon powering up, the 970 will search for
any .SDA files on all drives and finalize them to Broadcast Wave Files with a .WAV extension.
.SDA files can also be recovered to .WAV files with the FileSafe utility for Windows. ( See “FileSafe Util-
ity and the Sound Devices File Format”, page 58 )
File Splitting
Recorded files are split when the file size of Setup Menu option
[File Storage - Wave File Split Every] is reached (2GB or 4GB). A new file will be created and
grouped with the other files from the clip in the File View ( See “Storage and File Management”, page
39 ). When the Setup Menu option [System - Record Button File Split] is set to On, pushing the
Record Button during recording will begin a new file.
False Take
To discard the last take and delete the file (False take), press Stop () button + Rewind (<<) button. A
dialog box will appear warning that the last take will be deleted and indicate the file name. Use the
Control knob to highlight OK and push the Control knob to confirm.
