9 – Operations related to timecode–Recording timecode

TASCAM DA-98HR
1
Use the
Ó
and
Á
keys to select the “hours”
field.
2
Use the
§
and
¶
keys to set the “hours” value.
Here we assume (for simplicity) that the “hours”
value has been set to 00. If you set this to a different
value, add the appropriate offset as you read this
explanation.
Timecode is synthesized, starting at
00 57 00 00
,
allowing three minutes of timecode “pre-roll” before
the nominal start of the piece at
01 00 00 00
.
With
ABS-13
selected, once the tape is posi-
tioned approximately 13 minutes from the start, the
timecode restarts at
01 57 00 00
. If
ABS-23
has been selected, this occurs approximately 23 min-
utes after the start of the tape (the piece is 20 minutes
long). This allows another track to begin at
02 00
00 00
.
This process continues until the end of the tape is
reached. Wherever the tape is located, this calcula-
tion is performed, allowing you to locate each track
easily with reference to the timecode values.
The diagram below shows the relationship between
the “synthesized” timecode and the absolute time on
tape, assuming that the “hours” value has been set to
00.
9.2.5
Checking tape TC
The
TAPE TC
indicator by the tape counter lights
when either timecode recorded on tape
or
synthe-
sized from ABS is being read.
As well as the tape counter, the display screen can
also be used to show tape timecode values and the
frame rate currently recorded on tape, as described
below.
1
Go to menu group E, and move the cursor to
Tape TC
:
2
Start playing the tape.
3
The tape timecode value is displayed on the
bottom line, together with the system frame
rate.
If
TC Track
has been selected, but the
timecode which has been recorded on the tape
differs from the system frame rate, the frame
rate at the lower right of the screen will be pre-
ceded by an asterisk (
*
).
9.3
Recording timecode
This section refers to the process of actually striping
the timecode track with timecode.
9.3.1
Selecting the timecode source
The DA-98HR allows you to select one of three
sources for recording timecode: the DA-98HR’s
internal generator, an external source, or timecode
based on the “Tape TC” source.
To select the source for recording timecode:
1
Go to menu group 8, move the cursor to
TcRec Src
(source for timecode record-
ing), and press
ENTER
:
2
Use the
§
and
¶
keys to select a source for the
timecode recording from the following options:
Generator TC
,
Tape
and
External TC
.
If you select
Tape
, the source of the tape
timecode is also shown, as determined in the
tape timecode selection menu (9.2, “Tape time-
code mode”).
NOTE
Generally speaking, timecode should be recorded from an
external source only when audio tracks and timecode must
be transferred together from external units. In all other
