For example, if Reel=141001, Scene=101A, Take=001, Track=01, and the Track 1 Name is Boom, then
the file’s name would be 14001-101A-001_01Boom.WAV
Mono Wave files can be written to a maximum of 2 SSD’s. Recording Mono Wave files to a mechanical
(spinning) hard drive is not supported.
Poly (Wave) File Format writes a single file to each target drive per take. All armed audio tracks are
interleaved into a single file.
If File Name Format is set to Reel-Scene-Take_Track Name, but WAV poly files are being recorded, the
alternative format of Reel-Scene-Take will be used.
Audio Mode Settings
Certain Setup Menu options apply only to Audio Mode:
• [Timecode/Sync - Sync Ref - Audio Only Mode]: This determines the sync reference source clock
for audio mode. The source can be set to Internal, Word Clock (Sync In), AES1-2, MADI, Video
Input (SDI/HDMI), or Video Ref (Sync In).
After changing the Sync Reference in Audio Mode, allow approximately 10 seconds before recording.
• [Audio - Audio Mode Sample Rate]: This menu option only applies when the
[Timecode/Sync - Sync Ref - Audio Only Mode] is set to Internal. The default sample rate is 48
kHz. When sample rate is set to 88.2k or 96k, tracks 33 to 64 are disabled.
• [Audio - Audio Mode Bit Depth]: The bit depth of recorded audio in Audio Mode. The default Bit
Depth is 24. Audio Mode allows for 16- or 24-bit recordings.
• [Audio Mode - Pre-Roll Time]: In Audio Mode, a continuous audio buffer of up to 10 seconds
is maintained. The Pre-Roll Time will be “added” to the front of all audio recordings. Timecode
stamps are automatically adjusted to match the Pre-Roll time.
Changing the armed status of any track, changing the value of Setup Menu option
[Audio - Audio Mode Sample Rate], or changing the current audio synch reference will reset the pre-
roll buffer.
• [File Storage - Wave File Split Every]: The file size that will cause a .wav file split in Audio Mode.
At factory default audio files will automatically split when the file size reaches 4 GB. Audio record-
ings can also be split when the file size reaches 2 GB.
• [Timecode/Sync - Frame Rate (Audio Only)]: The frame rate that will be stored in the iXML and
Bext area of the .wav file. The default frame rate is 29.97 non-drop. The available frame rate options
are 23.976, 24, 25, 29.97, 29.97 drop-frame, 30, 30 drop-frame.
If the synchronization source (Setup Menu option [Timecode/Sync - Sync Ref -Audio Only Mode])
is lost while in record, the recording will stop. The Sync Reference OSD field will flash
red if the synchronization source is not present. The Audio Input OSD field will flash red if
there is a mismatch between the currently selected audio sync reference sample rate and the
[Audio - Audio Mode Sample Rate] setting.
Playback of audio clips is the same as video clips. see Playback Operation
