Chapter 2: Installation and Configuration 9
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 24-Bit ADAT Bridge audio inter-
face), connect the Clock output of the HD sys-
tem to the Slave Clock Input of the legacy
interface.
To connect a legacy audio interface to an
HD-series system with a SYNC peripheral:
1 Connect the SYNC peripheral to the HD-series
system with Loop Sync as described in the previ-
ous 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
interface.
MachineControl
On MachineControl-enabled Pro Tools systems,
SYNC peripherals support limited Serial Deck
Control only.
Serial Deck Control Mode
(Non-Linear Decks Only)
A limited degree of Serial Deck Control mode is
available through a connection to the 9-pin
ports on the SYNC peripheral. For full Serial
Deck Control, a direct serial connection to the
host Pro Tools computer is required.
To connect an external deck to a SYNC peripheral:
 Connect a standard 9-pin cable from one of
the 9-pin Out ports on the SYNC peripheral to
the 9-pin connector of the external deck.
As many as two decks can be connected to the
two 9-pin Out ports on the SYNC peripheral.
You can control one deck at a time, switching
between them from within Pro Tools. These
ports on the SYNC peripheral support all Machi-
neControl modes except 9-Pin Remote (Deck
Emulation) mode.
9-Pin Remote Deck Emulation
Mode
9-Pin Remote Deck Emulation mode requires a
direct serial connection to the host computer.
Clock for SYNC I/O, a 96 I/O, and an 888|24 I/O

configuration instructions.

Due to performance limitations, this
configuration should be used primarily
with non-linear decks.
