9 – Operations related to timecode–Timecode input and output
TASCAM DA-98HR

9.5.1
Timecode input
There are two primary reasons for the DA-98HR to
receive timecode: when the DA-98HR is chasing to
timecode, and must receive the master timecode, and
when the DA-98HR is to record timecode from
another unit (but see 9.3.5, “External timecode
sources” below).
To view incoming timecode, follow the procedure
described in 9.3.8, “Checking external timecode”.
9.5.2
Timecode output
The timecode received at the
TIME CODE IN
jack, or
the timecode recorded on tape, can be output from
the
TIME CODE OUT
jack
When the DA-98HR is the timecode master, the
timecode it outputs should be off tape.
However, when the DA-98HR is in the middle of a
timecode chain, you will probably want to retransmit
the incoming timecode (the
OUT
functions as a
THRU
).

Go to menu group 5, move the cursor to
OutTc Src
(output timecode source),
and press
ENTER
:

Using the
§
and
¶
keys, select one of the three
options:
Tape
; timecode will be replayed
off-tape,
External (regen)
; the
external timecode will be re-generated by the
DA-98HR’s generator, resulting in a clean sig-
nal, or
External (reshape)
; the
timecode signal will be simply filtered before
being re-transmitted.
NOTE
When the DA-98HR is in CHASE mode, and the tape time-
code mode has been set to
TC Track
), the timecode output from the DA-98HR
will be the received timecode, with the offset value (9.6.2,
“Setting timecode offset”) added or subtracted from it. This
means that any other units slaved to the timecode output
do not need to have separate offset settings, but can use
the master DA-98HR’s offset.
9.5.3
Timecode output format
This
Fast LTC
function controls the way in
which timecode is output when fast winding the tape,
or if shuttling is carried out at greater than normal
playback speed.
The
05 Frame
setting means that timecode
information is not output continuously. Here, the
DA-98HR reads the timecode from the tape as it is
spooling, outputs 5 consecutive frames at normal
speed starting with the value which has been read
from tape, then reads the tape again, outputs another
5 consecutive frames based on the new tape position,
and so on.
The
Leap
setting means that timecode is output
continuously during fast operations, and will not be
contiguous (it will leap between frames).
The
off
setting means that timecode is not output
during fast operations.

Go to menu group 5, move the cursor to
Fast LTC
and press
ENTER
:

Use the
§
or
¶
keys to select the option as
described above.
9.5.4
Timecode input and output
timing
Because of the nature of the digital-to-analog conver-
sion, the timecode which is input to and output from
the DA-98HR must be synchronized to match the
audio timing from either the digital (either the TDIF
or AES/EBU digital connectors depending on which
is currently selected using the AES/EBU key
inputs and outputs, or those of the optional analog
audio slot boards.
1
Go to menu group 5, move the cursor to
TC
Timing
(output timecode timing) and press
ENTER
:
2
Use the
Ó
and
Á
keys to select either the
Input
or the
Output
timing parameter.
3
Use the
§
and
¶
keys to select between
Analog
and
Digital
for that
parameter.
