Chapter 3: Connecting HD OMNI 19
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 among
the devices. For an example of connecting mul-
tiple Pro Tools|HD audio interfaces, see Figure 2
below.
To make Loop Sync connections:
1 Connect (daisy-chain) the Loop Sync Out of
each interface to the Loop Sync In of the next
interface with the BNC cables included with
your audio interface.
2 Connect the Loop Sync Out of the last inter-
face to the Loop Sync In of the primary interface
or SYNC peripheral.
