After this setup, check the following in the recorder (#2) and (#3).
* Blinking of “CHASE” in the display: This will change to constant lit upon completing chase lock in later
operation.
* “EXT SYNC” is lit in the display: This means it is externally synchronized against the input word clock
signal.
Check chase lock
1. When the master recorder (#1) is played back, MTC IN LED of the slave recorder (#2) and (#3) will be lit,
“CHASE” in the display will immediately change from blinking to lit and chase lock will be completed.
Check that the MTC time on display are same in both master and slave units.
2. When the master starts recording, the slave will also start recording upon completing chase lock.
3. When the master is stopped, the slave will also stop as MTC from the master will be interrupted.
“CHASE” in the display will change from lit to blinking.
4. During FF/REW, the master only will be in the FF/REW mode and the slaves will remain stopped but
when playback/recording is started, the slaves will immediately chase lock.
The unit re-chase window is fixed at “10 frame.” In other words, when MTC of the master and slave drifts
apart more than 10 frames, it will assume that chase lock is disengaged and the slave will match the
position again with the master (re-chase operation). During the re-chase operation, sound output will be
muted. If the drift is within 10 frames, the slave will recognize this and continue to travel.
Because the master supplies digital signal to slave in this system, re-chase is rarely carried out following
chase lock.
* Should the unit fail to correctly chase lock and control, re-check the connection /cables and all settings.
