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 15). For details, see
“Making inputs and outputs available to your host
software” on page 68. A quick and easy way to do
this is to choose the Audio Interface preset from
Quick Setup (item 10 on page 12).
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). Try setting the unit’s clock 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 interface.
In the Sound panel of System Preferences, the
828es 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 828es. Please see
“Monitoring through the 828es” on page 65.
How do I control monitoring latency?
See “Reducing monitoring latency” on page 64.
The Routing tab (page 15) 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 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 (optical 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 (such as the optical
banks), disable them in the Device tab (page 12).
I accidentally deleted my factory presets. How do I
restore them?
In the Device tab (page 12), click the Restore
Factory Presets button to restore all factory presets.
How do I factory reset my device?
Push the MENU knob to enter the main menu.
Navigate to
Settings > Factory Default and push
the MENU knob twice to reset.
I hear clicks and pops under word clock sync.
Many problems result from incorrect word
clocking. It is essential that all digital devices in
the system be word locked. Consult “Synchroni-
zation” on page 46 for detailed information on
how to word clock your gear. Whenever there is
any unexpected noise or distortion, suspect
incorrect word lock.
