Playback
The current take is indicated on the bottom of the Main View in large text. Press the Play () button
to play the current take (This operation will work from the Setup Menu as well). During playback,
the Play () button and Main View text are green. Pause playback by pressing the Play () button
during playback. The Play button flashes green to indicate playback is paused. Press the Stop ()
button any time to stop playback. From Stopped Mode in the Main View, press the Fast Forward (>>)
Button once to skip to the next file on the current Playback drive. Press the Rewind (<<) Button once
to skip to the previous file on the current Playback drive.
The current Playback drive is indicated by the green Drive Status Main View field. To browse files on
the Playback drive, press FILES. This will display the File List of the current Playback drive. Pressing
Play () in the File List will play the currently highlighted file.
To browse files on another drive, scroll beyond the top of the File List to access the drive selection
list. When a file is played, the drive it is played from will become the current Playback drive. When
a new take is recorded, the lowest numbered drive it is written to will become the current Playback
drive.
Playback audio is routed to audio outputs as determined by output routing options in the [Audio]
Setup Menu section. (
Files will always be played back at the sample rate of the 970, whether synced to external sources
or to internal sampling rates. The sample rate that the file was originally recorded at (and that is
stamped in the file’s header) will be ignored by 970 during playback, and the 970 will play the file at
the current sample rate, as determined by Setup Menu option [Timecode/Sync - Sync Ref].
Fast Forward and Rewind
Hold down the Fast Forward (>>) or Rewind (<<) button during playback to scrub forward or back-
ward. As the Fast Forward (>>) or Rewind (<<) button is held down, playback speed in that direction
will increase (up to 50x), as indicated in the top-right of the Main View. Release the button to resume
playback in real time.
Cue Markers
Cue Markers are defined timing points in a file that can be used for playback navigation on both the
970 and some 3rd party software applications.
Bit depth defines the digital “word length” used to represent a given sample and correlates to the
maximum dynamic range that is represented by the digital signal. Larger bit depths accommodate
more dynamic range. Sound Devices recommends 24-bit recording for all critical production.
Pre-Roll
To prevent missing record cues or up-cutting takes, the 970 has pre-roll buffering available. When
active, pre-roll begins recording at a set number of seconds preceding the record command. The Pre-
Roll time can be adjusted from 0 to 10 seconds the Setup Menu option [Audio - Pre-Roll Time].
Changing the armed status of any track, changing the value of Setup Menu option
[Audio - Sample Rate], or changing the current audio synch reference will reset the pre-roll buffer.
