The Samples Per Buffer setting also impacts how
quickly your audio software will respond when you
begin playback, although not by amounts that are
very noticeable. Lowering the Samples Per Buffer
will make your software respond faster; raising the
Samples Per Buffer will make it a little bit slower, but
barely enough to notice.
Monitoring live inputs without plug-in effects
As mentioned earlier, CueMix Console allows you
to monitor dry, unprocessed live inputs with no
delay at all. For complete details, see chapter 11,
"Reducing Monitoring Latency" (page 91).
Optical input/output
The Optical input and Optical output settings let
you choose between ADAT optical ('lightpipe') and
S/PDIF optical ('TOSLink') as the format for the
828mkII's optical input and output. Choose the
format that matches the device connected. If you
are not using the optical connections, it is
recommended that you turn them off (as provided
in the menus) to reduce bandwidth and processing
overhead. Note that you can operate the input and
output independently. For example, you could use
the ADAT optical format on the input (with a
digital mixer, for example) and optical S/PDIF on
the output (with a DAT deck, for example).
When the optical output is set to TOSLink, the
signal is split to both the RCA and optical output
jacks. However, when the optical input is set to
TOSLink, the RCA SDIF jack is disabled.
Phones
The Phones setting lets you choose what you will
hear from the headphone jack. Choose Main Outs
if you'd like the headphone output to match the
main outs. Choose Phones if you would like the
headphones to serve as their own independent
output, which you can access as an independent
output destination in your host audio software and
as an output destination for the four on-board
CueMix DSP mix busses.

Word Out
The Word Out menu appears when the 828mkII is
operating at a high sample rate (88.2 or 96kHz).
This menu lets you set the word clock output either
to match the current sample rate (System Clock) or
to halve the current sample rate (System Clock ÷ 2).
In the latter case, the word clock output would be
reduced to either 44.1 or 48 kHz.
Enable Sound Manager driver
Check the Enable Sound Manager option if you
would like to route Sound Manager audio to and
from the 828mkII. For example, you could listen to
an audio CD playing in the CD drive of your
Macintosh through headphones connected to the
828mkII. As another example, you could route
audio from a pair of 828mkII inputs into a third-
party Sound Manager-compatible audio
application. Use the menus provided to choose the
desired 828mkII inputs and outputs you would like
to route to/from Sound Manager. For further
details, see chapter 9, "Sound Manager" (page 1).
☛
This option is disabled when the 828mkII is
set to a high sample rate (88.2 or 96kHz).
Enable Pedal
Check the Enable Pedal option if a foot switch is
connected to the 828mkII and you would like to
trigger recording punch in/out (or other software
functions) with it. Use the Set buttons to determine
what keystroke is trigger by the pedal-up and
pedal-down positions. You can assign the pedal to
any two keystrokes you wish. (You are not
restricted to punch in/out.)
IF 828MKII SETTINGS ARE GRAYED OUT
If the MOTU FireWire driver is currently in use by
an audio program (or Sound Manager), some of its
settings cannot be changed and are therefore
grayed out in the MOTU FireWire Control Panel
menus. (Settings that cannot be changed are ones
on which audio applications continuously depend
for smooth, error free operation.) If you find that a
