TASCAM DA-98HR

In all other cases, we suggest using either the DA-
98HR’s internal generator or timecode from tape. If
you use these as sources, there will be no jitter prob-
lems, and any problems of synchronization with the
digital audio clock are eliminated
NOTE
When recording timecode from an external digital source, make sure the digital clock of the DA-98HR and that of the external source are synchronized, as explained in ?????????? and ??????????. A warning message will appear if the timecode
source and the DA-98HR are not synchronized, but timecode can still be recorded. However, the resulting timecode recording will probably cause synchronization problems in the future.
When recording timecode from a timecode generator
,
ensure there is a common video reference for both the DA-
98HR and the generator (set the
CLOCK
of the DA-98HR
to
VIDEO
).
When recording timecode from another DTRS unit
,
synchronize the two units using ABS chase (setting the
timecode/audio source unit to be a slave unit as described
in 8, “DTRS synchronization”). After the two units have
been synchronized in this way, timecode and audio can be
transferred together.
When recording timecode from a digital source (audio
or video)
, make sure that the DA-98HR and the other unit
are locked to a common word (audio recorder) or video
(video recorder) clock reference. After the two machines
have been synchronized in this way, timecode and audio
can be transferred together.
9.3.6
Recording timecode from an
analog recorder
When recording timecode from an analog recorder,
feed the analog recorder or its external synchronizer
and the DA-98HR with a common video source, and
use the video resolve function of the analog recorder
or synchronizer, if this is provided.
If the analog recorder has no video resolve function,
it may have a timecode chase function, which can be
driven by any timecode source from the following
list:
• timecode already recorded on an audio track of the
DA-98HR
• timecode recorded on other DTRS units, using
ABS chase with the DA-98HR
• timecode recorded on any other recorders synchro-
nized with the DA-98HR
• a timecode generator, video-synchronized with the
DA-98HR.
NOTE
Do not use any timecode recorded on the DA-98HR’s dedi-
cated subcode track as the timecode master when transfer-
ring timecode from an analog recorder.
If your analog recorder cannot chase to external time-
code, you must first record the timecode from the
analog recorder on an audio track of the DA-98HR
and then transfer the timecode to the dedicated time-
code track.
Timecode recorded on the audio track in this way is
synchronized to the audio clock, and can subse-
quently be transferred (through patching) to the time-
code track.

Recording timecode from
external sources
1
Set the
Time Mode
to
TC
2
Select the appropriate frame rate (9.4, “Select-
ing the frame rate”) which matches the incom-
ing timecode.
3
Set the timecode record source to
External TC
4
Press the
TC REC
key to arm the timecode
track.
5
Start the external source to check the status of
the external timecode.
If no external timecode has been received since the
DA-98HR has been switched on, the tape counter
will show all hyphens. (
-- -- -- --
).
If external timecode has been received since the DA-
98HR has been switched on, but is not currently
being received, the tape counter will flash.
If the external timecode is currently being received at
normal (play) speed, the tape counter will show the
value of the timecode currently being received. If the
external timecode is being received from a source in
fast wind mode, the tape counter will flash.
If the timecode source is not clock-synchronized
with the DA-98HR, a warning will be shown on the
display screen. In this case, although you can record
timecode, it is not recommended, as this will proba-
bly cause problems later on.
6
Stop the external timecode source, and rewind
or reset it to a point prior to where you want
recording to begin. The tape counter now
starts to flash.
7
Restart the source. The tape counter displays
the received timecode.
8
Press and hold down
RECORD
and press
PLAY
.
Timecode is recorded from the external source
onto the timecode track.
If the tape counter was flashing when the
TC
REC
indicator was flashing (the timecode track
was armed), the tape counter now shows all
hyphens, and nothing will be recorded (but any
