Chapter 2: Installation and Configuration 9
To connect SYNC I/O to Pro Tools|HD interfaces:
1 Using a BNC cable, connect the Loop Sync
Out of the SYNC I/O to the Loop Sync In of your
primary HD-series audio interface.
2 Connect the SYNC I/O Loop Sync In to the
Loop Sync Out of your HD-series interface.
When using more than one HD-series audio in-
terface, make SYNC I/O the first and last unit in
the Loop Sync chain.
Using Legacy Audio Interfaces with
Pro Tools|HD
If you are using a Pro Tools|HD system that in-
cludes a legacy audio interface (an 888|24,
882|20, 1622, or ADAT Bridge audio interface),
you will need to connect the Clock output of
the HD system to the Slave Clock Input of the
legacy interface.
To connect a legacy audio interface to an HD-
series system with SYNC I/O:
1 Connect SYNC I/O to the HD-series system
with Loop Sync as described in the previous
steps.
2 Using a BNC cable, connect the Ext Clock Out
of your primary HD-series interface to the Slave
Clock In of your first legacy interface.
3 If you are connecting multiple legacy inter-
faces, daisy-chain their Slave Clock connections
by connecting the Slave Clock Out of the first
interface to the Slave Clock In of the next inter-
face.
Connecting Slave Clock for
Pro Tools|24 MIX
To connect SYNC I/O to a Pro Tools|24 MIX-series
audio interface:
■ Using a BNC cable, connect the SYNC I/O
Word Clock Out to the Slave Clock In of your
primary audio interface.
