Installation fails.
Installation completes, but the computer does not
recognize the unit.
If some trouble is causing installation to fail, or installation
completes but the computer does not recognize the unit,
check the following.
1) USB indicator lit
Is the USB indicator on the front panel of the unit lit?
If the USB indicator is not lit, confirm that the USB cable is
properly connected.
NOTE
Always use the included USB cable.
2) Change the USB port
Since the unit might not function properly with some USB
ports, try connecting to a different built-in USB port on the
computer, and reinstall the driver (when using Windows).
NOTE
• Try again after disconnecting other USB devices. (USB
keyboards and USB mouse can be left connected.)
• Do not use a USB hub. Always connect the unit directly to a
built-in USB port on the computer.
3) Stop other software running in the background
Since antivirus software and other software that runs in
the background can interfere with installation, stop other
software before beginning installation.
See “3 − Installation” on page 11 of this manual for how
to install and uninstall the driver.

There is no sound even when audio is playing back.
The audio output must be set on the computer.
Please confirm the following while the unit is connected to
the computer.
Note that after making the following settings, sound will be
output through the unit, but no sound will be output by the
computer's speakers or headphone jacks.
Windows 8/7/XP
Make the settings for the operating system as described in
the previous chapter (6 – Application Guide).
Set the default playback device for Windows 8 by
completing steps 1–4 and for Windows 7/XP by completing
steps 1–3.
Mac OS X
1. Shut down all applications and open “System Prefer-
ences” from the Apple menu.
2. Open “Sound”.
3. From the “Output” tab, select “TASCAM US-366”.
After completing the settings, restart the computer and
check the playback sound.
Depending on the application you are using, other device
settings might also be necessary in addition to those
above.
In particular, since DAW (Digital Audio Workstation)
software operates using audio engines that are different
from OS settings, confirm the DAW driver settings first after
installing the driver for this unit. Check the manuals for the
software that you are using for details about how to make
these settings.
Please see the manuals for the applications that you are
using for detailed setting procedures.
8 The sound breaks up or there is noise.
The processing load on the computer can cause sound to
break up and noise to occur.
Some ways to reduce the load on a computer are introduced
below.
1)
If a wireless LAN, antivirus software or other software
are running in the background, they regularly use the
computer's CPU, and this burden can cause sound to
break up and noise to occur.
Stop wireless LAN transmission, antivirus software and
other software running in the background when using
this unit.
2) Try increasing the buffer size (latency) setting in the
audio application that you are using and/or in the
control panel for this unit.
NOTE
Consult the maker of your audio application for methods to
reduce its burden on your computer.
3) Change the settings of your computer so that they are
optimal for audio processing.
