Carrying Out Synchronized Operation - Sony PCM-3348HR Operation Manual

7-1 Sector-Based SynchronizationOverview
7-1-2 Carrying Out Synchronized
Operation
This section assumes the following synchronization
points, by way of example.
Master unit: 00 01 00
H MIN SEC
Slave unit 1: 00 01 10
H MIN SEC
Slave unit 2: 00 00 55
H MIN SEC
1
Mount a tape with a CTL signal recorded on it on
each of the PCM-3348HR units.
2
For all units, set the REC MODE switch on the
PCM-3348HR system control block to INSERT.
3
Set the timer display mode on all of the RM-
3348HR units to CTL absolute or CTL relative
display mode.
4
Stop the tape on each PCM-3348HR unit at the
point to be synchronized.
5
On the RM-3348HR slave unit 1, press and light
the SLAVE button.
This automatically computes the sync offset time
(10 seconds) for slave unit 1, and shows it in the
LOCATE TIME display.

For a few seconds, until synchronization is
achieved, the REMOTE 3 lamp of the SYNC
CLOCK switch on the PCM-3348HR system
control block flashes, and the EXT CLOCK
ERROR lamp lights, but then automatically the
REMOTE 3 lamp changes to light continuously,

The above operations start synchronized operation of
the PCM-3348HR. O nce synchronized operation
starts, the tape transport of all three units is under the
control of the RM-3348HR for the master unit, and on
the slave PCM-3348HR and RM-3348HR units all
tape transport buttons except the STOP button (that is,
FF, REW and PLAY buttons) are disabled.
Pressing the STOP button on one of the slave RM-
3348HR units releases that unit from the slave mode.
If the SLAVE button does not operate
If pressing the SLAVE button produces an indication
"ILLG" on the LOCATE TIME display, it means that
the synchronized operation mode cannot be selected.
This occurs in the following cases.
• When the tape transport on the master or slave PCM-
3348HR unit is not stopped.
• If the sampling frequencies on the master unit and
slave unit are different.
• If the timer display mode on the master unit or slave
unit is not CTL.
Displaying the time code during the
synchronized operation
Press the CTL/TC button with the time code set to
REPRO. The playback time code appears in the TAPE
TIME display.
When you press the CTL/TC button again or the
synchronized operation mode is released, the timer
display mode returns to the CTL display mode.
