Chapter 4: Installing Pro Tools | Sync X

Word Clock contains no positional information. If you want devices to play or record in sync, you still need to provide them with a po-
sitional reference. Sync X can generate timecode to provide positional reference to other devices (see Generating and Regenerating
Timecode). If frame edge sync is required, you must use Video Reference (Internal or External) (see Video Reference).
To input Word Clock to Pro Tools | Sync X:
 Using a shielded BNC cable, connect Word Clock from the master device (such as Pro Tools | MTRX) to the WC IN port on Sync X.
To output Word Clock from Pro Tools | Sync X:
 Using shielded BNC cables, connect any of the six WORD CLOCK OUT ports on Sync X to the Word Clock input of digital devices
(such as Pro Tools | MTRX) that you want to clock to Sync X.
Connecting AES Devices
To input AES clock reference to Pro Tools | Sync X:
 Connect the device’s AES output to the AES3 I/O (XLR to DB-25) or AES3-id IN (BNC) port on Sync X (cable sold separately).
To output AES clock reference from Pro Tools | Sync X:
 Connect the AES3 I/O (DB-25 to XLR) or AES3-id OUT (BNC) port on Sync X to the AES reference input on the digital device
(cable sold separately).
Connecting MTC Devices
Pro Tools | Sync X provides a 9-pin to two 5-pin DIN break out cable for making MTC (MIDI Time Code) connections. The MIDI Out
port supplies MTC—derived from conversion from LTC or Bi-Phase—to synchronize MTC-compatible consoles, sequencers, lighting
systems, and other devices. MTC output from Sync X is independent of Pro Tools MTC generation. Sync X always outputs MTC in par-
allel with its LTC output.
MIDI Time Code from the MTC Out port always matches the timecode address displayed on the front panel of Sync X. To supply MTC
from Sync X to another MTC-compatible device, connect the device as described below.
To connect an MTC-compatible device to receive MTC from Pro Tools | Sync X:
1 Connect the included MIDI I/O break out cable to the MIDI I/O port on Sync X.
2 Using a standard MIDI cable, connect the MIDI Out port on the Sync X break out cable to the appropriate MIDI input on the device.
Pro Tools and MTC
Pro Tools | Sync X does not respond to incoming MTC at this time. A separate MIDI interface is required for Pro Tools to receive MTC.
MTC is output constantly whenever Sync X is generating timecode. This output can be muted when timecode (LTC) is idle.
The MIDI In port is not used since Sync X does not respond to incoming MTC at this time.
For more information, see Generating MTC.
