Sound Devices 633 - Manual (Page 56)

Timecode Hold Off
Some devices that send rec-run timecode will sometimes have a tendency to send short bursts of
running timecode or incorrect values. When using timecode to trigger recording on the 633 (External
timecode auto-record modes) this behavior can result in unintentional recordings or incorrect time-
code stamps on the 633. To eliminate these problems, the 633 features a Timecode Hold Off function.
When using external timecode auto-record modes, the 633 will wait (“hold off”) for the amount of
time specified in Setup Menu option TIMECODE > Hold Off before beginning recording. Running
timecode lasting less than the Timecode Hold Off value will not trigger a recording on the 633.
Things to consider when using Timecode Hold Off:
• This feature only applies in Ext-TC Auto-Rec and Ext-TC Auto-Rec/Cont.
• If Pre-Roll is set, it will be applied (
See “Pre-Roll”, page 36 ). Pre-Roll will only capture au-
dio from the initial detection of a timecode signal. If no Pre-Roll is selected, the file will begin
after the Hold Off time expires. It is best practice to set Pre-Roll, in the Setup Menu option
RECORDER > Pre-Roll Time , to a value greater than the selected Timecode Hold Off value. This en-
sures that audio is captured from the moment a timecode signal is detected and that unintentional
files triggered by short bursts of timecode are not generated.
