I cannot hear any sound even when audio is played
back on the computer.
Confirm that the MONITOR BALANCE knob on the unit is not
turned all the way to the left (toward INPUT). If that is the case,
turn the MONITOR BALANCE knob to the right of center.
In addition, check the status of the unit's connection with the
computer.
Moreover, if you make the following settings, sound will be
output through this unit, but no sound will be output by the
computer’s speakers or headphone jack.
Windows 7/8
See the “8 – Application Guide” on page 16 ”- “Windows 8”
or “Windows 7” instructions in the “Windows Media Player”
section in this manual, and make settings as necessary for
the OS.
Conduct “procedures 1–4 for Windows 8” or “procedures 1–3
for Windows 7” to set the default device for playback.
Mac OS X
1. Quit all applications and open “System Preferences…” from
the Apple menu.
2. Open “Sound”.
3. On the “Output” tab, select “US-2x2” or “US-4x4”.
After completing the setting, restart the computer and
check the sound of playback. Depending on the application
that you are using, you might need to make additional
device settings. In particular, DAW software operate using
audio engines with settings that are different from the

Sound breaks up or there is noise.
The processing load on the computer causes sound to break up
and noise to occur.
Here are some methods to reduce the load on the computer.
1. A wireless LAN and software running in the background,
including antivirus software, regularly put processing loads
on the computer, which can cause sound to break up and
other noise.
Stop wireless LAN transmission, antivirus software and other
software running in the background when using this unit.
2. Set the buffer size (latency) in the audio application that you
are using or in this unit's Settings Panel to a larger value.
NOTE
Consult the maker of the audio application that you are
using for methods to reduce its load on your computer.
3. Change the settings of your computer so that they are
optimal for audio processing.
