Naming computer input and output channels
Click on any computer input or output name in
the routing grid (Figure 8-6) to change its name.
These names appear in your host audio software.
Streaming computer audio to and from the
on-board mixer
In the Routing grid, you’ll see mixer inputs across
the top of the grid, including Main, Monitor, Aux,
etc. (item 11 on page 15). These are output buses
from the 828es on-board mixer. To route one of
these mix buses 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.
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 828es connected
directly to the computer. For information about
how to set this up, see “Mapping computer
channels to network streams” on page 99.
Mirroring computer channels to multiple
outputs
Figure 8-6 shows an example of mirroring one
stereo audio stream from host audio software to
several outputs. In the example, computer
channels 1-2 are being sent to Phones 1-2, Phones
3-4 and Main L-R. To route a source to multiple
destinations, click multiple boxes in its column,
(see computer channels 1-2 in Figure 8-6).
Combining multiple sources 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 16).

WORKING WITH ON-BOARD MIXING AND
EFFECTS
The 828es provides powerful mixing, EQ,
compression and reverb, which can operate hand-
in-hand with your host’s mixing environment. For
example, the 828es can serve as a monitor mixer,
routing channels to musicians, or it can serve as an
integrated extension of your host’s mixing
environment. You can even save a particular
mixing configuration as a preset for future recall.
For details, see “Mixing tab” on page 16.
LTC-TO-MTC CONVERSION
When connected to a Mac, your MOTU interface
can convert SMPTE time code (LTC) to MIDI
Time Code (MTC), allowing any MTC-
compatible host audio software to resolve to MTC.
LTC-to-MTC conversion can be done even when
the Clock Mode setting for the MOTU interface is
set to
Internal (or any other setting). Note that the
Clock Mode setting does NOT have to be set to
LTC . In other words, the interface can convert
LTC to MTC even when it is not resolving its
audio engine to the incoming time code. This
allows your DAW host software to resolve to time
code with fast lockup response.
