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 Avid HD audio
interfaces, see Figure 4 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 a BNC
cable.
2 Connect the Loop Sync Out of the last interface to the Loop Sync In of the primary interface or SYNC
peripheral with a BNC cable.
