MOTU FIREWIRE AUDIO CONSOLE

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 Traveler’s 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.
