Operating The Traveler-Mk3 As Aconverter; Making Sync Connections - MOTU Traveler-mk3 User Manual

OPERATING THE TRAVELER-MK3 AS A
CONVERTER
As explained earlier in "Using optical I/O to
operate the Traveler-mk3 as a 16-channel
expander" on page 20, the Traveler-mk3 can serve
as a multi-channel analog-to-digital converter
when disconnected from the computer and instead
connected to another device equipped with an
ADAT optical input. For example, you could
connect the Traveler-mk3 optical output to the
optical input on another MOTU audio interface,
such as a Traveler, 896mk3 or even another
Traveler-mk3. The Traveler-mk3 then serves as a
multi-channel expander that adds additional mic,
analog TRS and digital inputs to the interface. The
benefit of connecting the Traveler-mk3 in this
manner (instead of as another FireWire interface)
is that you can seamlessly integrate the
Traveler-mk3's inputs into the on-board no-

latency CueMix monitor mixing in the interface,
since the Traveler-mk3's inputs are fed into
CueMix via the interface's optical inputs.
If the device to which you are connecting the
Traveler-mk3 supports 2x optical sample rates
(88.2 or 96 kHz), you can also use both banks of
connectors as discussed in "ADAT optical
operation at 88.2 or 96 kHz" on page 20.

MAKING SYNC CONNECTIONS

If you connect devices digitally to the
Traveler-mk3, or if you need to synchronize the
Traveler-mk3 with an outside time reference such
as SMPTE time code, you must pay careful
attention to the synchronization connections and
clock source issues discussed in the next few
sections.
