Sample rate
Choose the desired overall sample rate for the
Traveler-mk3 system and Digital Performer. Newly
recorded audio in Digital Performer 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
Digital Performer 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 Digital
Performer 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 Digital
Performer. 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 Digital
Performer. 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
Digital Performer'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 Digital Performer, 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 1-2 bus, but you can assign
them to mirror any other output bus you wish.
Return Assign
In Digital Performer's audio input menus and the
Bundles window, you'll see an Traveler-mk3 input
called Return 1-2 (Figure 7-2). 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 you would like to hear on
this return. This can be used, for example, to
