TRAVELER SETTINGS
Sample Rate
Choose the desired Sample Rate for recording and
playback. The Traveler can operate at 44.1 (the
standard rate for compact disc audio), 48, 88.2, 96,
176.4 or 192kHz. Make absolutely sure that all of
the devices connected digitally to the Traveler
match the Travelers sample rate. Also make sure
that your Digital Timepiece, MIDI Timepiece AV
or other digital audio synchronizer matches it as
well. At the 4x sample rates (176.4 or 192kHz), all
digital I/O on the Traveler is disabled.
Mismatched sample rates cause distortion and
crackling. If you hear this sort of thing, check the
sample rate settings in your hardware and here in
the MOTU FireWire Audio Console.
Operation at 4x sample rates (176.4 or 192kHz)
At the 4x sample rates (176.4 or 192kHz),
operation of the Traveler is restricted, due to the
higher audio bandwidth demands, as follows:
All digital I/O is disabled (there is no optical,
TOSLink, S/PDIF or AES/EBU input/output).
The Traveler provides 8 channels of analog input
and 8 channels of analog output, simultaneously.
The Mix1 input, as described in “Mix1 1-2” on
page 65, is not available.
The headphone output can be assigned to any
analog output pair or the Phones setting (as
described in “Phones on page 44). But at the 4x
sample rates, the Phones output is not available
from the computer. Instead, it is only available as a
destination for the four CueMix DSP mixes. In
other words, it can only take CueMix inputs.
The main outs mirror the phones.
Clock Source
The Clock Source determines the digital audio
clock that the Traveler will use as its time base. For
a complete explanation of synchronization issues,
Figure 5-1: The MOTU FireWire Audio Console gives you access to all of the settings in the Traveler hardware.
