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.
