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 12) and
routed to and from the computer in the Routing
tab (“Routing tab” on page 14). For details, see
“Making inputs and outputs available to your host
software” on page 50.
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 se t t i ng t h e un it’s clock s ou rce 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, the
Stage-B16 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 the Stage-B16. Please see
“Monitoring through the Stage-B16” on page 53.
How do I control monitoring latency?
See “Reducing monitoring latency” on page 53.
The Routing tab (page 14) doesn’t display some of
the inputs or outputs on my interface.
What is the sample rate? Some digital I/O formats
are not available at 4x sample rates (176.4 or 192
kHz). Also, the Routing tab only displays input and
output banks that are enabled in the Device tab
(page 12), 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 (AES/EBU banks, for
example, when only working with analog banks, or
all output banks when only working with Phones).
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, disable them in the Device tab
(page 12).
I accidentally deleted my factory presets. How do I
restore them?
In the Device tab (page 13), click the Restore
Factory Presets button to restore all factory presets.
How do I factory reset my device?
Press and hold in the PHONES knob for five
seconds. After the LEDs flash to indicate that the
unit is ready for a factory reset, turn the PHONES
knob one click left or right to initiate the reset.
Clicks and pops due to hard drive problems...
If you have checked your clock settings and you are
still getting clicks and pops in your audio, you may
have a drive related problem. Set your Clock
Source to Internal and try recording just using the
analog inputs and outputs on the Stage-B16. If you
encounter the same artifacts you may want try
