Connecting Loop Sync
If you are using two or more HD audio interfaces or a SYNC peripheral, Loop Sync must be connected
to maintain proper clock synchronizations among the devices. For examples that include a SYNC pe-
ripheral, see the SYNC HD Guide. For an example of connecting multiple Avid HD 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 a BNC ca-
ble.
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.
