If you do not have any digital audio connections to
your 828x (you are using the analog inputs and
outputs only), and you will not be slaving your host
software to external SMPTE time code, choose

Internal

.

If you have devices connected to the 828x optical
ports, see “Choosing a clock source for optical
connections” on page 28.

If you are slaving the 828x and your host software
to SMPTE time code, follow the directions in
chapter 10, “MOTU SMPTE Setup” (page 115).

Phones Assign

This 828x setting lets you choose what you’ll hear
from the headphone jack. For example, if you
choose

Main Out 1-2

, the headphones will

duplicate the main outs, or you can choose any
other output pair. If you choose

Phones 1-2

, this

setting makes the headphone jack serve as its own
independent output pair. As a result, you’ll see

Phones 1-2

as an additional audio destination in

your host’s audio output menus.

Optical input and output

To make a 828x optical input or output available in
your host software, choose the appropriate format
(

ADAT optical

or

TOSLINK)

from the optical input

and/or output menu. If you won’t be using the
optical connectors, turn them off.

Main Outs Assign

Use the Main Outs Assign setting to determine
what audio you will hear on the main outs of the
828x. If you would like to treat them as their own
separate output pair, choose

Main Out 1-2.

Return Assign

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

Return 1-2

. This is a

stereo feed from the 828x that matches the signal of
one of its output pairs. Use the Return Assign menu
in MOTU Audio Setup to choose which output pair

you would like to hear on this return. This can be
used, for example, to record back a final stereo mix
that includes effects processing from the 828x DSP
(such as the Leveler) for reference and archiving
purposes.

Warning: the Return inputs can cause

feedback loops! DO NOT assign this input to a
track that shares the same output as the Return
Assign setting.

Reverb return

The 828x also supplies a return to your host
software that carries the output of its reverb
processor. This return can be used for any purpose
you wish.

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 Audio driver.
Check the audio system or audio hardware
configuration window in your software. There is a
menu that lets you choose among various drivers
that may be in your system. Choose the MOTU
Audio driver from this menu.
