Time Code Menu - Nagra Seven Operating Instructions Manual

TIME CODE MENU

This menu allows the access and setting of all the time code options of the machine. It permits the setting of
the internal time code generator, for both TIME and USER data, as well as frame rate selection and the time
code mode. It also allows the choice of the time code to be recorded and external references to be used.
THE INTERNAL TIME CODE GENERATOR
Source
This is used to choose which time code is to be used. If an external time code is present on the LEMO
connector, external time code can be selected by using the up or down arrow key.

Chapter IV
The Nagra Seven will record TC from the internal
generator.
The Nagra Seven will record TC from an external source.
If Assemble is selected each time the machine is put into REC mode a full
time code assemble will be performed. This is done by calculating the time
code value of the sample following the last sample of the previous index.
There will be no time code discontinuity between indexes.
In the Jam Sync position, the internal time code generator will
automatically be set as soon as a valid time code is connected to
the time code input connector. If the cable providing the external
time code signal is left connected to the machine, a new jam sync
will be performed automatically as soon as the machine detects a
difference between the internal time code generator and the
external signal of more than 2 ms. In order for the jam sync
function to operate when the cable is connected, certain
conditions are verified before the set is made. The incoming TC
must be at the correct speed (± 1%) for 10 consecutive frames.
Frozen or reverse time code will prevent a jam of the generator
from occurring.
