Using the [5V DC] port
Even when the UR22mkII is connected to a
computer, you can supply power via the [5V DC]
port by external power supply if the [POWER
SOURCE] switch is set to the [5V DC] side. Using
an external power supply can help to prevent noise
and other audio degradation caused by drawing
power from the USB terminal of a computer.
2 [POWER SOURCE] switch
For selecting the port for supplying power to the
UR22mkII.To supply bus power via the [USB2.0]
terminal, set this switch to the [USB2.0] side. To supply
power via the [5V DC] port, set this switch to the [5V
DC] side. When using an iPad, set this switch to the
[5V DC] side. Even if you set the power supply to [5V
DC], the power to the UR22mkII will not come on
unless it is connected to a computer or an iPad by the
[USB 2.0] terminal.
NOTE
When using a USB mobile battery, if the power of a computer
or iPad connected to the [USB 2.0] terminal is off, the power
supplied via the [5V DC] port is also stopped to prevent
wasteful consumption of the battery.
3 [USB2.0] terminal
For connection to a computer or an iPad.
NOTICE
Be sure to observe the following points when connecting
the device to the computer's USB interface.
Failing to do so may result in the computer freezing or
shutting down, as well as corruption or even loss of data.
If the device or computer does freeze, restart the
application or computer.
• Use an AB type USB cable. USB 3.0 cables are not
supported.
• Be sure to wake the computer from
sleep/suspended/standby mode before connecting it to
the UR22mkII with a USB cable.
• Before connecting/disconnecting the USB cable, quit
all open software applications on the computer.
• Before connecting or disconnecting the USB cable
from the [USB2.0] terminal, be sure to set all output
level controls to the minimum.
