Troubleshooting

A
APPENDIX
My MOTU interface isn't showing up in Audio MIDI
Setup on my Mac.
Due to the updated architecture of the new macOS
High Sierra (10.13 and above), the system
extensions for all newly-installed third-party
software will automatically be blocked from
running. If your MOTU interface is not showing
up in Audio MIDI Setup, CueMix 5 or your DAW,
you might need to enable the driver in your
System Preferences. To do so, first download and
install the very latest installer for your MOTU
interface. After restarting, open System
Preferences. Select Security & Privacy. In the
General section, click the Allow button. The Allow
button will disappear 30 minutes after installation.
To display the Allow button, run the installer for
the MOTU driver again.
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 word LOCK in the front panel displays 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
UltraLite-mk5 should be selected as the output
device.
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 UltraLite-mk5. Please see
"Monitoring through the UltraLite-mk5" on
page 46.
How do I control monitoring latency?
See "Reducing monitoring latency" on page 46.
How do I factory reset my device?
Push the SELECT knob to enter the main menu.
Navigate to RESET and push the SELECT knob
twice to reset.
I hear clicks and pops under optical or S/PDIF sync.
Many problems result from incorrect sync
settings. See "Choosing a clock source for optical
connections" on page 24 and "S/PDIF" on
page 24. Whenever there is any unexpected noise
or distortion, suspect digital clocking issues.
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 UltraLite-mk5. If
you encounter the same artifacts you may want try
using another drive in your computer. Clicks and
pops can also occur when the drive is severely
fragmented or there are other drive-related issues.
Connecting or powering gear during operation...
It is not recommended that you connect/
disconnect, or power cycle connected devices
while recording or playing back audio. Doing so
may cause a brief glitch in the audio.
