A Troubleshooting
Some or all of my MOTU interface inputs and
outputs are not available in my host audio
software.
Make sure that the inputs and outputs are enabled
in the Device tab (“Device tab” on page 14) and
routed to and from the computer in the Routing
tab (“Routing tab” on page 16). For details, see
“Making inputs and outputs available to your host
software” on page 56.
I have absolutely no audio input or output
happening to or from my interface. Why?
Make sure that the unit has a stable sample rate (the
sample rate will flash if the clock hasn’t settled yet).
Tr y s ett ing the unit’s clo ck source to Internal if you
can’t sync to any external clock sources. Check that
audio is working with Internal sync, and if so, then
work on establishing a stable external clock.
I can't hear computer audio output through my
MOTU AVB interface.
In the Sound panel of System Preferences, your
MOTU AVB interface should be selected as the
output device. Almost all applications will use just
the first two output channels, so make sure that
From Computer 1 and From Computer 2 are routed
to the physical outputs that you are listening to in
the Routing tab (e.g. Phones 1-2 or Analog 1-2).
How do I monitor live inputs?
Please refer to the documentation for the audio
application that you are using. If your application
does not support input monitoring, you will need
to use the mixer in your MOTU interface. Please
see “Monitoring through your MOTU interface”
on page 59.
How do I control monitoring latency?
See “Reducing monitoring latency” on page 59.
The Routing tab (page 16) doesn’t display some of
the inputs or outputs on my interface.
The Routing tab only displays input and output
banks that are enabled in the Device tab (page 14),
so be sure any banks you wish to work with are
enabled there. However, to conserve DSP resources
and help consolidate screen-space in the other
tabs, it is efficient practice to disable unused input
or output banks (optical banks, for example, when
only working with analog banks).
I'm getting a “Could not enable this effect because
DSP is overloaded” error. What should I do?
Disable other effects or reduce the number of mixer
inputs to conserve DSP resources. If there are audio
input and output banks on your interface that you
are not using (such as the optical banks), disable
them in the Device tab (page 14).
I accidentally deleted my factory presets. How do I
restore them?
In the Device tab (page 14), click the Restore
Factory Presets button to restore all factory presets.
How do I factory reset my device?
Push the SELECT knob/button to enter the main
menu. Navigate to Settings > Factory Default and
push the SELECT knob/button twice to reset.
I can’t authenticate AudioDesk.
When authenticating AudioDesk, the OK button
does not become active until you have entered in
your name and a valid keycode. Your name must
contain at least three characters, and you must
enter the keycode exactly as it appears (on the
jacket of your AudioDesk installer disc). If you
continue to have difficulties, try repairing
Mac OS X disk permissions using Disk Utility.
