Quick Reference:
MOTU FireWire Audio Console
Check this option if the audio software you
are using with the 896HD does not support
Windows WDM drivers and instead only
supports legacy MME (Wave) drivers. When
checked, this option makes all of the 896HD
inputs and outputs available to legacy Wave-
driver compatible audio software.
Determines the clock source for your 896HD.
If you’re just using the analog ins and outs,
set this to ‘Internal’. The other settings are
for digital transfers via AES/EBU or external
synchronization via the ADAT SYNC in port.
Enables or disables the 896HD’s
ADAT optical I/O. Turning them off
frees up FireWire bandwidth.
Choose the global sample rate
for the system here.
Provides several options for the
MOTU 896HD’s AES/EBU sample
rate conversion. See, “Syncing
AES/EBU devices” on page 28.
This menu lets you choose what you will hear
from the headphone jack. To mirror the main
outs, choose
Main Outs . Or you can mirror any
other output pair. To hear the phones as their
own independent output, choose
Phones .
Click the tabs to access general
MOTU FireWire interface settings
or settings specific to the 896HD
(or other connected interface.)
Choosing a smaller setting here
reduces the delay you may hear
when listening to live input that
you are running through effects
plug-ins in your software. But
lower settings also increase the
strain on your computer. For
details, see “Samples Per Buffer”
on page 38.
Click the 896HD tab to access
these settings.
If you have a foot switch connected to the
896HD, these settings let you map the foot
switch to any computer keyboard key for
both the up and down position. For details
about how to set this up, see “Enable Pedal”
on page 39.
This option should always be left
on (checked). There are only a few
rare cases in which you would
want to turn it off. For details,
refer to the MOTU tech support
database at www.motu.com.
There are several ways to access these settings:
■
From the Windows Start menu, choose Programs>MOTU>MOTU
FireWire Audio Console.
■
From within Cubase SX, go to the Device Setup window and click
the
Control Panel button.
■ From within other applications, refer to their documentation.
How to access these settings
Lets you choose what to monitor with the
896HD’s programmable front panel meters.
If you are running the 896HD interface at a 2x
or 4x sample rate (88.2 to 192kHz), this
option appears at the bottom of the interface
settings. It lets you choose a word clock
output rate that either matches the global
sample rate (e.g. 192kHz) or forces a word
clock output rate of either 44.1 or 48kHz.
Takes the interface off line. Inputs and
outputs are not available to audio applica-
tions, and bandwidth on the FireWire bus is
relinquished, freeing it up for other devices.
The Clip Hold Time controls how
long the top-most red LED
remains illuminated after
clipping. Choose ‘Infinite’ if you
want to be able to clear the LED
from Digital Performer. The
Peak
Hold Time controls how long the
highest illuminated LED remains
lit before going dark.
