Naming computer input and output channels
Click on any computer input or output name in the
routing grid (Figure 7-6) to change its name. These
names appear in your host audio software.
Streaming computer audio to and from the
on-board mixer
In Figure 7-6, you'll see "mix" inputs across the top
of the grid (Main, Monitor, Aux, etc.) These are
output busses from the your interface's on-board
mixer. To route one of these mix busses to your
host computer software, click the grid at the
intersection of the mix column and desired
computer channel row. Now, the mix bus output
will be routed to the computer via the channel you
selected.
Figure 7-6: An example of routing computer channels (from host audio software) to physical outputs on a 1248. The two headphone outs are
mirroring the main outs (channels 1-2 from the computer). In this example, 30 channels are being used for streaming from the host
computer, but more can be added for streaming to the AVB network or the on-board 48-channel mixer in the 1248.

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 109.
