MOTU FIREWIRE AUDIO CONSOLE
44
Traveler’s opt ica l input and output. Choose the
format that matches the device connected. If you
are not using the optical connections, it is
recommended that you turn them off (as provided
in the menus) to reduce bandwidth and processing
overhead. Note that you can operate the input and
output independently. For example, you could use
the ADAT optical format on the input (with a
digital mixer, for example) and optical S/PDIF on
the output (with a DAT deck, for example).
When the optical output is set to TOSLink, the
signal is split to both the RCA and optical output
jacks. However, when the optical input is set to
TOSLink, the RCA S/PDIF jack is disabled.
Phones
The Phones setting lets you choose what you will
hear from the headphone jack. Choose Analog 1-2
if you’d like the headphone output to match the
main outs. Choose Phones 1-2 if you would like the
headphones to serve as their own independent
output, which you can access as an independent
output destination in your host audio software and
as an output destination for the four on-board
CueMix DSP mix busses.
At the 4x sample rates (176.4 and 192kHz), the
headphone output can be assigned to any analog
output pair or the Phones 1-2 setting, as described
above. But at the 4x sample rates, the Phones
output is not available as an output destination for
software on the computer. Instead, it is only
available as a destination for the two CueMix DSP
mixes. In other words, it can only take CueMix
inputs.
Word Out
If you are running a Traveler interface at a high
sample rate (88.2, 96, 176.4 or 192kHz), the Wo r d
Out menu appears in the interface tab (as shown in
Figure 5-1 on page 40). This menu lets you choose
a word clock output rate that either matches the
global sample rate (e.g. 176.4 or 192kHz) or
reduces the word clock output to the
corresponding 1x rate (either 44.1 or 48kHz). For
example, if the Traveler is operating at 176.4kHz,
choose Force 44.1/48kHz to produce word clock
output at 44.1kHz.
To m a t ch the Traveler’s sample rate, choose System
Clock. To reduce the word clock rate to the
corresponding 1x rate, choose Force 44.1/48kHz.
Wave support for legacy (MME) software
Windows only exposes the first two channels of a
multi-channel WDM audio stream to applications
which use the legacy (MME) multimedia interface.
The Enable full Wave support for legacy (MME)
software (less efficient) option forces the Traveler
multimedia driver to expose all channels as stereo
pairs, providing full MME support.
If your host audio software does not directly
support WDM audio and instead only supports
legacy MME drivers, use this option to access
multiple Traveler input and output channels.
If your host audio software does directly support
WDM audio, leave this option unchecked for
optimal performance.
This option is only available when the multimedia
driver has been installed, and it defaults to being
not checked.
