Time Code
27
00:00:00:00 at power-up. When switching to record run from another mode, the internal generator
will stop at the last number generated. A user-defi ned value can be jammed into the internal genera-
tor from the jam menu.
Continuous Jam:
The onboard time code generator will re-jam from external time code whenever time code is con-
nected to the TC input. Similar to free run mode, the generator runs continuously without regard to
record mode. For a jam to occur, the time code signal must be disconnected and re-connected to the
time code input. Continuous jam is useful when slaving additional recorders to a master recorder.
Slaves should be set to continuous jam to follow the master time code device.
24 Hour Run
Identical to free run with the exception that the generator will automatically jam itself from the
time-of-day clock on power-up. The generator will also re-jam if the time-of-day clock is reset. Once
jammed, the generator will run continuously from the time code clock, not the time-of-day clock.
If the time-of-day clock is reset during the production day, the time code generator value will change. You
must re-jam all time code devices to ensure proper synchronization.

Time code setup is done from the jam menu, Timecode Jam Menu. Pressing the drive key and
menu keys simultaneously quickly enters the jam menu. In this menu, the top of the display
shows the value of signal present on the time code input and the bottom of the display shows the
currently set time code value. In addition, the 744T displays the frame rate of the incoming time code
and the current frame rate setting of the 744T. If there is a mismatch between the incoming and 744T-
set time code frame rate the incoming frame rate value will fl ash.
The 744T time code generator can be set in three ways.
Jam RX TC
To jam the internal generator to the external value, press the enter key or the Multi-Function Control-
ler button. The screen will say “JAMMING”. Once the 744T is jammed to the external time code, the
external and internal numbers will match and run in sync.
Identical to the Ambient Recording series of time code products, the 744T time code generator is capable
of “cross jamming” differing frame rates. The 744T will cross jam time code at the top of the second giv-
ing phase-accurate (the 00 frames will match) time code at the frame rate set in the 744T instead of the
incoming frame rate.
Jam Zeros
This menu selection resets the internal generator to zero.
