the proper hardware connections. Use the
synchronization diagrams to be clear about how
you will be synchronizing your audio software and
the Traveler to the other components of your
system.
Synchronizing digital audio connections
If you have devices connected to the Traveler
digital inputs (optical or RCA S/PDIF), you need to
be concerned with the synchronization of the
Traveler’s d i g ital audio clo ck w it h other de v ices
connected to it digitally (if any). For example, if
you have a digital mixer connected to the Traveler
via an ADAT optical light pipe cable, you need to
make sure that their audio clocks are phase-locked.
For details, see “Syncing optical devices” on
page 34 and “Making sync connections” on
page 27. If you don’t have any digital audio devices
connected to the Traveler, digital audio phase-lock
does not apply to you.
Slaving to SMPTE time code
If you need to slave your audio software and the
Traveler sys tem to SMPTE time code, follow the
instructions in your software’s manual for slaving it
to MIDI Time Code (MTC). To ensure that your
audio tracks don’t drift out of sync with your MIDI
tracks or the time code, use a hardware
synchronizer like the MOTU MIDI Timepiece AV
or Digital Timepiece to slave the Traveler hardware
to the SMPTE (or MIDI Time) Code as well. A
digital audio synchronizer is required for drift-free
SMPTE/MIDI time code sync. Make sure the Clock
Source setting in the MOTU FireWire Audio
Console is set to Word C l ock In. For examples of
how to set this up, see “Syncing to video and/or
SMPTE time code using a synchronizer” on
page 33.
MIDI I/O VIA THE TRAVELER MIDI PORTS
Once you’ve run the Traveler software installer as
explained in “Installing the Traveler software” on
page 17, the Traveler MIDI ports will appear as a
MIDI input source and output destination in
Sonar’s MIDI I/O menus.
24-BIT OPERATION
Yo u r Tr av e l e r h a r d w a r e fully supports 24-bit
recording in any audio software that supports it.
Simply enable 24-bit operation as instructed by the
software. The Traveler system always supplies the
software with a 24-bit data stream, and when you
enable 24-bit operation, it simply uses all 24-bits
supplied by the Traveler hardware.
