3.8 Working with Timecode
The D424 provides an LTC timecode input that allows to record LTC
timecode. When playing back a sequence consisting of takes with different
timecode positions, the D424 will provide a contiguous timecode defined
by the first take.
3.8.1 Recording Timecode
• Check for correct timecode wiring by selecting [INP TC] . The incoming
code should be displayed.
• When recording timecode, be sure that the timecode source and the D424
are running synchronously. The usual way is to provide a common video
reference signal.
• Enable timecode recording with [TC RDY] . When the corresponding LED
is on, the timecode position will be added to the audio information of all
subsequent recording sessions.
Notes: The timecode information will be recorded as a single TC stamp at the
beginning of an audio file. Timecode jumps during recording will not be
considered.
Timecode can be recorded only together with audio channel(s) set to
ready.
3.8.2 Playing Back Timecode
The D424 always provides the current position at the TC output connector.
If no timecode was recorded, the absolute position is present. During
STOP or CUE, a stationary code is generated.
3.8.3 Chasing to Timecode
In chase mode, the recorder is following an external timecode.
• When chasing to a master timecode, make sure that the master and the
D424 are running with the same reference clock. Both master and D424
must be configured to the same timecode format.
• Start/stop the chase mode with [CHASE] .
Chase LED is On: Chase mode is on, D424 runs synchronously in PLAY mode.
Chase LED is Flashing: Chase mode is on, but D424 waits because the master is not in PLAY
mode (STOP or fast forward/rewind).
• An offset can be applied by storing a value (±12 hours) into the nominal
offset register. It is accessed with
[REG] [0] .
• An “instant lock” command will lock the D424 at the current position by
storing the current offset to the nominal offset register and launching the
chase mode. The command is performed with
[LOC+CHASE] or with the
[INST LOCK] key of the desktop controller.
