Working with AVB network streams
Audio channels going to networked AVB interfaces
can be streamed to and from your host audio
software through the MOTU interface connected
directly to the computer. For information about
how to set this up, see “Mapping computer
channels to network streams” on page 73.
Mirroring computer channels to multiple
outputs
Figure 7-1 shows an example of mirroring one
stereo audio stream from your host audio software
to several outputs. In the example, computer
channels 1-2 are being sent to the main outs, plus
phones 1-2 and phones 3-4. To route an input to
multiple outputs, click multiple boxes in its
column, (see computer channels 1-2 in Figure 7-1).
Combining multiple inputs to one output
To merge (mix) any channels in the grid (computer
streams or otherwise), route them to mixer inputs
and then use the on-board mixer (“Mixing tab” on
page 17).

CHOOSING THE MOTU AUDIO DRIVER
Once you’ve made the preparations described so
far in this chapter, you’re ready to run your audio
software and enable the MOTU AVB audio driver,
which allows your host software to use the the 24Ai
or 24Ao as an audio interface.
For Mac OS X audio software
For audio software running under Mac OS X, go to
the menu item or preference where you choose the
audio device (Core Audio driver) you wish to use,
and then select the the 24Ai or 24Ao by name.
For Windows audio software
For audio software running under Windows, go to
the menu item or preference where you choose the
ASIO driver you wish to use, and then choose
MOTU AVB USB ASIO . If your host audio software
doesn’t support ASIO, choose the MOTU AVB USB
AUDIO Wave driver instead.
