MOTU Traveler-mk3 User Manual page 21

To learn how to program the Traveler-mk3 when it
is operating as a stand-alone expander in this
fashion, see chapter 6, "Traveler-mk3 Front Panel
Operation" (page 43).
Choosing a clock source for optical connections
When connecting an optical device, make sure that
its digital audio clock is phase-locked (in sync
with) the Traveler-mk3, as explained in "Making
sync connections" on page 26. There are two ways
to do this:
1. Resolve the optical device to the Traveler-mk3
2. Resolve the Traveler-mk3 to the optical device
For 1), choose Internal (or any other clock source
except ADAT optical) as the clock source for the
Traveler-mk3 in MOTU Audio Setup.
For 2), choose either ADAT Optical A or ADAT
Optical B as the Traveler-mk3's clock source
(Figure 3-7). Be sure to choose the optical port that
the device is connected to.

For details about using the clock source setting and
the MOTU Audio Setup software in general, see
chapter 5, "MOTU Audio Setup" (page 37).

Using word clock to resolve optical devices
If the optical device you are connecting to the
Traveler-mk3 has word clock connectors on it, you
can use them to resolve the device to the
Traveler-mk3, similar to the diagram shown in
Figure 3-18 on page 29 for S/PDIF devices with
word clock. Also see "Syncing word clock devices"
on page 30.
S/PDIF
If you make a S/PDIF digital audio connection to
another device, be sure to review the digital audio
clocking issues, as explained in "Syncing AES/EBU
and S/PDIF devices" on page 29. The Traveler-mk3
supplies +12dB of digital trim (boost) for the
S/PDIF input pair, which can be adjusted from
CueMix FX ("Input trim" on page 83) or the front
panel ("The IN (inputs) menu" on page 49).
AES/EBU
Connect standard AES/EBU input and output.
2x sample rates (88.2 & 96 kHz) are supported; 4x
samples rates (176.4 or 192kHz) are not supported.
Be sure to review the digital audio clocking issues,
as explained in "Syncing AES/EBU and S/PDIF
devices" on page 29.
The Traveler-mk3 supplies +12dB of digital trim
(boost) for the AES/EBU input pair, which can be
adjusted from CueMix FX ("Input trim" on
page 79) or the front panel ("The IN (inputs)
menu" on page 46).
