Connecting Loop Sync
If you are using two (or more) Pro Tools audio interfaces or a SYNC peripheral, Loop Sync must be
connected to maintain proper clock synchronization among the devices. For examples that include a
SYNC peripheral, see the
SYNC HD Guide. For an example of connecting multiple audio interfaces, see
Figure 2 below.
To make Loop Sync connections:
1
Connect the Loop Sync Out of each interface to the Loop Sync In of the next interface with the BNC
cables included in your audio interface.
2
Connect the Loop Sync Out of the last interface to the Loop Sync In of the primary interface or SYNC
peripheral.
