Connecting Word Clock Devices
SYNC peripherals have Word Clock input and
output ports, which can be used simultaneously.
Use Word Clock when you want the SYNC pe-
ripheral to lock to 1x clock from DAT machines,
DA-88s, and similar digital devices.
Pro Tools|HD audio interfaces each have their
own Word Clock inputs, which provide addi-
tional clock options and flexibility. Refer to
Pro Tools|HD documentation for details.
To input Word Clock to a SYNC peripheral:
Connect Word Clock from the master Word
clock signal or device to the SYNC peripheral
Word Clock In.
To supply Word Clock from a SYNC peripheral:
Connect the SYNC peripheral Word Clock
Out to the Word Clock input of a digital device.
Make sure the SYNC peripheral Word Clock Out
port is configured to 1x for Word Clock.
Word Clock contains no positional informa-
tion. If you want devices to play or record in
sync, you'll still need to provide them with a
positional reference.
SYNC peripherals can generate time code to
provide positional reference to other devices.
See "Generating & Regenerating Time
Code" on page 49.
Connecting AES/EBU Devices
To input AES/EBU clock reference to a SYNC
peripheral:
Connect the device's AES/EBU output to the
SYNC peripheral AES/EBU input.
To supply AES/EBU clock reference from a SYNC
peripheral:
Connect the SYNC peripheral AES/EBU out-
put to the AES/EBU reference input on a DAT
machine or other digital device. (AES/EBU clock
does not support 176.4 kHz or 192 kHz sample
rates.)
Connecting MIDI Time Code
Devices
The SYNC peripheral MTC Out port supplies
MIDI time code, derived from conversion (from
LTC, VITC or Bi-Phase) or from MTC generation,
to synchronize MTC-compatible consoles, se-
quencers, lighting systems, and other devices.
MIDI time code from the MTC Out port always
matches the time code address displayed on the
SYNC peripheral front panel. To supply MTC
from the SYNC peripheral to another MTC-com-
patible device, connect the device as described
below.
To connect an MTC-compatible device to receive
MTC from a SYNC peripheral:
Connect the SYNC peripheral MTC Out port
to the appropriate MIDI input on the device, us-
ing a standard MIDI cable.
