Rewriting The Sync Offset Time - Sony PCM-3348HR Operation Manual

7-1-3 Rewriting the Sync Offset
Time
You can rewrite the sync offset time while the PCM-
3348HR tape transport is stopped, or is in playback,
fast forward or rewind mode.
rehearsal, locate, return playback, or auto punch in/out
operations, it is not possible to rewrite the sync offset
time.
Procedure
Use the following procedure to rewrite the sync offset
time.
1
Press the SF.mS/F.S button to set the LOCATE
TIME display to the mSEC mode.
2
Press and light the RECALL button, then press the
SYNC OFFSET button to display the sync offset
time in the LOCATE TIME display.
3
Enter the change to the sync offset time using the
numeric buttons.
For example, to reduce the value by 55
milliseconds, press the –, 5, 5, and = buttons in that
order. To increase the value, press the + button in
place of the – button.
4
Press and light the STORE button, then press the
SYNC OFFSET button.
This saves the amended sync offset time.
The PCM-3348HR unit connected to the slave
RM-3348HR unit on which you changed the sync
offset time operates in synchronization with the
new sync offset time.
Adjusting the value with the TRIM +/–
buttons
Holding down the SYNC OFFSET button, press the
TRIM +/– buttons to adjust the value.
After adjustment, the new sync offset time is saved.
During recording,
Adjusting the value using the numeric
buttons
If you already know the new value of the sync offset
time which is required, use the following procedure.
1
Using the numeric buttons, display the required
sync offset time in the LOCATE TIME display.
2
Press and light the STORE button, then press the
SYNC OFFSET button.
This saves the value entered in step 1 as the sync
offset time.
Preserving the sync offset time value
Once you press the SLAVE button turning it off, the
synchronized operation mode is exited, and the sync
offset time is preserved, but will be deleted next time
you press the SLAVE button, turning it on.
To preserve the sync offset time for use in a
subsequent synchronization operation, before
switching to the synchronized operation mode, recall
the stored sync offset time, and make a note of it.
Synchronized operation
• If you use variable speed playback or vari-sync
playback on the master RM-3348HR unit, the slave
units will follow the varying synchronization.
• There is a delay of approximately 2 seconds until the
slave unit catches up with the master unit, to establish
the servo lock. If you are carrying out auto punch in/
out operation, this extra time is automatically added
to the preroll time.
• Times shown on the slave unit are the times shown
on the master PCM-3348HR unit, after correction by
the sync offset time.
For example, if the sync offset time is
"00 00 10 000 ", and the punch in point is
H MIN SEC mSEC
"00 02 50 ", when you press the AUTO PUNCH
H MIN SEC
button the respective times shown in the LOCATE
TIME display are as follows.
Master unit: 00 02 50
H MIN SEC
Slave unit: 00 03 00
H MIN SEC
