outputs, check MOTU Audio Setup to make sure
they are enabled. If you don’t plan to use either
optical bank, turn it off to conserve computer
bandwidth.

Remember that the main outs and headphone
output can be configured in MOTU Audio Setup to
mirror other outputs. In addition, the 828x optical
banks can be disabled or configured as either
ADAT optical or TOSLink. This will affect how
they appear (and if they appear at all) in your host
software’s audio input lists. See “Optical input/
output” on page 43, “Phones Assign” on page 43
and “Main Out Assign” on page 43.

Number of channels

If your host audio software requires that you
specify the number of audio voices or channels you
will be using, be sure to choose enough channels to
cover the 16 inputs and 16 outputs provided by
your 828x.

Mix1 1-2 return bus

In your host audio software audio input menus,
you’ll see an 828x input called

Mix1 Return 1-2

.

This is a stereo feed from the 828x that matches its
main outs (Mix 1). This can be used, for example,
to record a final stereo mix for reference and
archiving purposes.

Warning: the Mix1 Return 1-2 return inputs

can cause feedback loops! DO NOT assign this
input to a track assigned to the 828x main outs.

For Mix1 Return 1-2, you can choose whether or
not to include audio being sent to the main outs
from the computer. See “Mix1 Return Includes
Computer” on page 94.

The “Phones 1-2” output

Host audio tracks assigned to the

Phones 1-2

output pair will be heard on the headphone jack
only. If the Phones are set to mirror another output

(such as the main outs), the mirrored audio stream
is mixed with the phones audio output. For further
explanation, see “Phones Assign” on page 43.

Audio Input and output names

The 828x audio driver supplies text string labels for
its inputs and outputs to clearly identify each one,
but some applications do not display these labels.
For information on how you can identify each
input and output in a numbered list like this, see
Appendix B, “Audio I/O reference” page (123).

PROCESSING LIVE INPUTS WITH HOST
PLUG-INS

If you patch a live input (such as a MIDI
synthesizer) through a plug-in effect in your host
software, you might hear a slight delay. There are
several ways to reduce this delay. For details, see
chapter 8, “Reducing Monitoring Latency”
(page 63).

WORKING WITH CUEMIX FX MIXING AND
EFFECTS

The 828x provides powerful external mixing, EQ,
compression and reverb, which you can operate
hand-in-hand with your host’s mixing
environment. For example, the 828x can serve as a
monitor mixer, routing channels to musicians, or it
can serve as an integrated extension of your host’s
mixing environment. If you program a 828x
mixing and processing configuration that goes
hand in hand with your host project, be sure to use
the file save features in CueMix FX to save the 828x
settings as a file in your host project folder for
instant recall of all settings. See chapter 9, “CueMix
FX” (page 69) f
or complete details.
