To link units:
1 . Connect multiple units as shown in the illustration above.
2. Set all linked recorders to the same sampling rate, bit depth, file format, and time code frame rate (if
used). This will ensure that all files generated are compatible.
3. If time code is being used, set slave units to External time code mode so that they will follow the master
recorder’s time code generator.
4. Set scene names on each of the units for easy identification in post production. Take numbers should be
set to the same on all linked recorders if take numbers are reset before recording. There is no file name
synchronization with multiple unit linking.
When linked, record start and stop on slave units will not affect units “above” in the linked chain.
This makes it possible for units to get out of synchronization if a unit other than the master is set to
record or stop. Using the master unit will assure that all machines begin and end recording together.
Master/Slave relationships between C.Linked recorders is established immediately after the C.Link
Out to C.Link In connection is made. To reverse the Master/Slave relationship, power down all
recorders, establish the new Master/Slave relationships by reconnecting the C.Link Out to C.Link In
connectors in the desired sequence, then power on all units in order of their Master/Slave relation-
ships.
The master recorder in a C.Link connection can not receive wordclock sync from anywhere else. It must
be the master wordclock source for all C.Link slaves.
The C. Link jack is a proprietary RS-232 port. Under no circumstances should analog or digital telephone
lines be connected to either jack. Serious damage to the recorder could result.
Outputs – Analog and Digital
The 744T has two two-channel output buses , the Master Output Bus and Output Bus 2. Each of these
buses is assigned audio sources independently, enabling the 744T to feed multiple outputs with
unique program.
The chart below shows the audio sources available for the each channel of the Master Output Bus
and Output Bus 2 connections. The audio sources for each output bus are selected in the Setup
Menu.
