7-2 Time Code Chase
Recalling the sync offset
Press the RECALL and SYNC OFFSET buttons in
that order.
The sync offset time appears in the LOCATE TIME
display in frame units.
When the sync offset is changed during time
code chase operation
If the difference between the new value and the old
value is not more than 2 frames, the re-synchronization
is achieved without interrupting playback.
If the difference between the new value and the old
value exceeds 2 frames, playback is first interrupted,
then the re-synchronization is carried out.
Relationship between sync offset and time
code values
The relationship between the time code values depends
on the sign of the sync offset, as follows.
• When positive
The slave time code value is ahead of the maser time
code value.
• When negative
The slave time code value is behind the master time
code value.
• When the offset is zero
The slave time code value is the same as the master
time code value.

7-2-7 Time Code Chase Operation
Before carrying out a time code chase operation, first
make the settings described in the sections from
"Selecting the chase mode" (page 7-7) to "Setting the
Sync Offset" (page 7-9) .
Then, use the following procedure to carry out a time
code chase operation.
1
Start playback on the master unit, or input the
external time code.
2
Ensure that the tape transport on the slave PCM-
3348HR is stationary, then press and light the TC
CHASE button.
This starts time code chase operation, and the
display units of the LOCATE TIME display switch
to subframes.
The display appears as follows.
• For the first few seconds after starting chase
operation
LOCATE TIME display: sync offset
Upper CUE display: "oF"
• Thereafter
LOCATE TIME display: offset discrepancy
Upper CUE display: "Er"
