Time Code Recording - Nagra Seven Operating Instructions Manual

Displaying time code
Time code is always in the HH.MM.SS.FF format and the user bits correspond to either the "date" format of
DD.MM.YY.xx or the "Free" format of xx.xx.xx.xx
The time code is displayed on the main screen of the Nagra. If the main function selector is in the TEST (pre-
record) position then the time code and user bits which are displayed on the screen are the values that are to
be recorded. This may be the internal generator or an external source depending on the menu selection.
In the STOP position of the main function selector, the display will show the time code and user bits of the file
current take. If the machine was previously in RECORD then this will correspond to the last time code value of
the last take recorded.
In the PLAYBACK mode, the displayed time code and user bits correspond to the selected take being played
back.

Time code recording

Recording of time code is completely automatic and will record time code according to the settings of the time
code menus. Time code on the Nagra Seven is recorded in the header of the audio file (as opposed to
longitudinally in parallel with the audio as in analogue recorders). This does mean that for the time code to be
read by another device (for example a PC) the program reading the file must be capable of interpreting the
header information, otherwise only the audio will be played back.
At the moment a recording is started the time code to be recorded is corrected according to the pre-record
buffer duration setting, thus keeping the time code coincident with the audio start point.
Time code "Assemble" recording can be selected in the menu. If so, the new take recorded will have a time
code stamp corresponding to the consecutive frame number of the last frame from the last recorded take in
the currently selected working directory.
If a new "take" is created during recording by pressing the "New Index" button then the time code system will
always make an assemble edit.
