13 – Time code synchronization
In this chapter, we explain playback synchronization with
timecode.
This unit’s playback and recording can be synchronized with
SMPTE time code input through the TIMECODE IN connector on
the rear panel.
For recording and playback, this unit can be synchronized with
SMPTE timecode input through the TIMECODE IN connector on
its rear panel or with its built-in timecode generator (“master
timecode” hereafter).
Time code synchronization differs according to the operation
mode.
Playback synchronized with timecode
Timeline mode
In timeline mode, playback can be synchronized with master
timecode.
When playing back with time code synchronization, when
playback starts, it synchronizes with master timecode.
Take mode
(Support is planned in a future firmware version upgrade.)
Playlist mode
(Support is planned in a future firmware version upgrade.)
Recording synchronized with timecode
Timeline mode
In timeline mode, recording can be synchronized with master
timecode.
When recording with time code synchronization, master
timecode is captured the instant that recording starts, and
recording starts from that time (timecode time) on the timeline.
Take mode
Chase and rechase are not possible.
The timecode from the built-in timecode generator is captured
at the beginning of recording as the file starting time.
Playlist mode
In playlist mode, recording is not possible regardless of timecode
synchronization status.
Basic operation
1. In timeline or take mode, load the session that you
want to record in or play back. In playlist mode, load
the session that you want to play back. (Support for
modes in addition to timeline mode is planned for a
future firmware version upgrade.)
2. Either of the following operations will enable
synchronized playback.
 While pressing and holding the SHIFT key, press the
CALL [CHASE] key on the front panel.
 On the
SYNC page of the SYNC T/C screen, set TC
Chase to ON .
3. In timeline mode, when recording or playback starts
time code synchronization also starts and the CHASE
indicator on the Home Screen appears green.
4. Press the STOP key during recording or playback with
time code synchronization to stop the transport. The
CHASE indicator on the Home Screen blinks when
stopped.
5. To resume recording and playback with time code
synchronization, repeat steps 3 and 4.
6. Either of the following operations will turn
synchronization off.
 While pressing and holding the SHIFT key, press the
CALL [CHASE] key on the front panel.
 On the
SYNC page of the SYNC T/C screen, set TC
Chase to OFF .
After doing this, playback and other unit operations
continue. The CHASE indicator on the Home Screen is
replaced with the
TC indicator.
Time code offset
You can set an offset for master timecode synchronization.
By doing so, you can synchronize to master timecode for
playback with a set time difference (see “SYNC page” on page
74).
Rechase
This unit continues to monitor master timecode even after
synchronized playback starts. Should the playback time of this
unit and the master timecode become unsynchronized for any
reason, the unit can “rechase” the timecode. You can set
whether or not the unit uses rechase and the degree of the
discrepancy before rechasing (see “SYNC page” on page 74).
CAUTION
During synchronized recording, this unit only synchronizes to master time
code once at the start of recording. There is no rechase function as there is
with synchronized playback.
