Conversely, you can stream audio from the
computer into the mixer. Channels coming from
the computer are represented across the top of the
routing grid as inputs. To route a computer channel
to the mixer, click the grid at the intersection of the
computer channel column and the desired mix
input row. Now, that computer channel will be
routed to the mixer input.
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 79.
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 21).
