Sample rate
Choose the desired overall sample rate for the
Traveler-mk3 system and AudioDesk. Newly
recorded audio in AudioDesk will have this sample
rate. Imported audio or soundbites in existing files
that do not match this sample rate will be displayed
in the Soundbites window with a red 'X' on their
move handles to indicate that they cannot be
played.
Clock Source
This setting is very important because it
determines which audio clock the Traveler-mk3
will follow.
If you do not have any digital audio connections to
your Traveler-mk3 (you are using the analog inputs
and outputs only), and you will not be slaving
AudioDesk to external SMPTE time code, choose
Internal.
If you have digital audio devices connected to the
Traveler-mk3, or if you are not sure about the clock
source of your setup, be sure to read "Making sync
connections" on page 26 and "Clock Source" on
page 39.
If you are slaving the Traveler-mk3 and AudioDesk
to SMPTE time code via the Traveler-mk3 itself,
choose SMPTE and follow the directions in
"Syncing to SMPTE time code" on page 28.
Buffer Size
The Buffer Size setting can be used to reduce the
delay — or monitoring latency — that you hear
when live audio is patched through your
Traveler-mk3 hardware and AudioDesk. For
example, you might have MIDI instruments,
samplers, microphones, and so on connected to
the analog inputs of the Traveler-mk3. If so, you
will often be mixing their live input with audio
material recorded in AudioDesk. See chapter 10,
"Reducing Monitoring Latency" (page 71) for
complete details.

Phones Assign
This Traveler-mk3 setting lets you choose what
you'll hear from the headphone jack. For example,
if you choose Analog 1-2, the headphones will
duplicate the main outs. Or you can choose any
other output pair. If you choose Phones 1-2, this
setting makes the headphone jack serve as its own
independent output pair. As a result, you'll see
Phones 1-2 as an additional audio destination in
AudioDesk's audio output menus. Audio tracks
assigned to this output pair will be heard on the
headphone jack only. For further explanation, see
"Phones Assign" on page 41.
Optical input and output
To make an Traveler-mk3's optical inputs and/or
outputs available in AudioDesk, choose ADAT
Optical or TOSLink from the optical input and/or
output menus. If you won't be using the optical
connectors, turn them off. Note: these settings can
only be accessed in the MOTU Audio Setup
application. For details, see "Optical input/output"
on page 41. If you are operating the optical ports at
88.2 or 96 kHz using the ADAT format, also see
"ADAT SMUX Type" on page 48.
Main Outs Assign
Use the Main Outs Assign setting to determine
what audio you will hear on the TRS main outs of
the Traveler-mk3. By default, they of course are
assigned to the Analog Out 1-2 bus, but you can
assign them to mirror any other output bus you
wish.
Return Assign
In AudioDesk's audio input menus and the Bundles
window, you'll see an Traveler-mk3 input called
Return 1-2 (Figure 8-2). This is a stereo feed from
the Traveler-mk3 that matches the output of one of
its output pairs, or any mix bus output (when
operating at 44.1 or 48 kHz). Use the Return Assign
menu in MOTU Audio Setup to choose which
output pair or mix bus you would like to hear on
this return. This can be used, for example, to
