TASCAM DA-78HR
To set the MTC output on or off:
2
Press the
SUB MENU
key until the display
shows
MTC ON (
MTC ON
) or MTC OFF (
MTC
OFF
).
3
Use the ▲ and ▼ keys to change the setting to
the required value (on or off).
To set the MTC output when fast or stopped:
2
Press the
SUB MENU
key until the display
shows either
FAST. MTC (
FAS T
MTC
) or
STOP. MTC (
STOP MTC
), followed by the cur-
rent setting (
on
or
off
).

Use the ▲ and ▼ keys to change the setting to
the required value (on or off).
NOTE
If MIDI is turned off using the MIDI menu (10.1,
“MMC enable and disable”), MTC output is also
disabled.
9.4.5 Fast linear timecode (LTC) output
The 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 play-
back speed.
1
Press the
SHIFT
key so that the
SHIFT
indicator
is flashing, then press the
MENU
key until the
display shows
TC-- (
TC--
).
2
Press the
SUB MENU
key so that the display
shows
FAST LTC (
FAS T LTC
) briefly, and
then changes to the current setting.
3
Use the ▲ and ▼ keys to make the appropriate
setting.
There are three settings:
The
5FRM (
5 FRM
) setting means that timecode
information is not output continuously. Here, the
DA-78HR 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 (
LEAP
) setting means that timecode is
output continuously during fast operations, and will
not be contiguous (it will leap between frames).
The OFF (
OFF
) setting means that timecode is not
output during fast operations.
9.4.6 Timecode output timing
Because of the nature of the digital-to-analog conver-
sion, the timecode which is output from the DA-
78HR must be synchronized to match the audio tim-
ing from either the digital or the analog audio out-
puts, whichever set of outputs is in use at the time.
1
Press the
SHIFT
key so that the
SHIFT
indicator
is flashing, then press the
MENU
key until the
display shows
TC-- (
TC--
).
2
Press the
SUB MENU
key so that the display
shows
OUT. TC. TMG (

) briefly,
and then changes to the current setting.

and ▼
keys to select between
ANALOG (
ANALOG
) and DIGITAL
(
DIGITAL
).
9.5 Recording timecode
9.5.1 Selecting the timecode source
The DA-78HR allows you to select one of three
sources for recording timecode: the DA-78HR’s
internal generator, external timecode, or timecode
based on tape.
To select the source for recording timecode:
1
Press the
SHIFT
key so that the
SHIFT
indicator
is flashing, then press the
MENU
key until the
display shows
TCG. REC-- (
TCG REC--
).
2
Press the
SUB MENU
key so that the display
shows
TC. REC. SRC (
TC REC SRC
) briefly,
and then changes to the current setting.
3
Use the ▲
and ▼ keys to select a source for the
timecode recording from the following options:
EXT (
EXT
), TCG (
TCG
—timecode generator)
and
TAPE. TC (
TAPE TC
).
If you select
TAPE. TC, the source of the tape
timecode will be used , 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 cases, we suggest that you use the
internal generator or the tape as sources for record-
ing timecode.
