9.4.1 Showing input timecode

There are two primary reasons for the DA-78HR to
receive timecode: when the DA-78HR is chasing to
timecode, and must receive the master timecode, and
when the DA-78HR is to record timecode from
another unit (but see 9.5.5, "External timecode
sources" below).
To view incoming timecode, follow the procedure
below:
1 Press the
SHIFT key so that the
is flashing, then press the
display shows (
2 Press the
SUB MENU
shows (
the current setting.
3 Use the
and keys to change between
(TAPE) (off-tape setting),
timecode received at the timecode input) and
(DIFF
—the difference between the
received timecode and the actual position). Use
EXT to view the received timecode.
NOTE
Even when the DA-78HR is in ABS mode, this setting
has some effect. If T APE is selected here, the ABS
tape time is shown. If DIFF is selected here, and the
DA-78HR is chasing using DTRS sync, the difference
between the ABS time of the master unit and the
slave unit is shown.
To show the frame mode of the incoming timecode:
1 Press the
SHIFT
key so that the

2 Press the

external timecode frame mode. If no external
timecode is being received, the display shows:
( EXT -- ).

9.4.2 Timecode input timing

Because of the nature of analog-to-digital conver-
sion, the timecode input to the DA-78HR must be
synchronized either to the audio from the digital or
analog outputs.

9.4.3 Timecode output

The timecode received at the timecode input jack, or
the timecode recorded on tape (or synthesized from
ABS), can be output from the timecode output jack.
When the DA-78HR is the timecode master, the
timecode it outputs should be off tape.
However, when the DA-78HR is in the middle of a
timecode chain, you will probably want to retransmit
the incoming timecode (the
THRU ). This section explains how to perform these
operations.

ted by the DA-78HR.

9.4.4 MTC output

It is possible to select whether or not the DA-78HR
outputs MIDI timecode, and under what circum-
stances. The following functions are available:
• MTC output
• MTC output in fast modes (allows sequencers, etc.
to keep track)
• MTC output when stopped
The last two of these are dependent on the first, i.e. if
MTC is set to be off, it cannot be output in fast or
stop modes. All of these are accessed from the MIDI
menu:
