Rear Panel

1 [POWER SOURCE] switch
For selecting the port for supplying power to the UR22C.
To supply bus power via the [USB 3.0] port, set this switch
to the [USB 3.0] side. To supply power via the [5V DC]
port, set this switch to the [5V DC] side.
2 [USB 3.0] port
For connection to a computer or iOS device.
NOTICE
When connecting to a computer with a [USB 3.0] port,
observe the following to prevent the computer from freezing
or shutting down, as well as corruption or even loss of data.
• Before connecting/disconnecting the USB cable, be sure to
observe the following points.
- Quit all open software applications on the computer.
- Set all output level controls to the minimum.
• Wait at least six seconds between connecting/
disconnecting the USB cable.
Apple accessories may be required when connecting the UR22C
with iOS devices. For details, refer to the UR22C Startup Guide.
3 [5V DC] port
For connecting a USB power adapter or USB mobile
battery. Use a power supply when connecting the UR22C
to a device that does not supply sufficient bus power,
such as an iPad. (The UR22C does not include a USB
power adapter or USB mobile battery.)
NOTICE
• Read the safety precautions for the USB power adapter or
USB mobile battery that you use.
• Use a USB power adapter or USB mobile battery that can
supply power in compliance with USB standards with a 5-
pin micro USB plug.
Output voltage 4.8 V to 5.2 V
Output current 0.9 A or greater
Using the [5V DC] port
Even when the UR22C 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. This can be used to avoid power
supply problems. For example, ground loops due to
differences in voltage potential can occur if the device
connected to the UR22C is using the same power outlet
as the computer, and audio quality degradation can
occur if the power supply from the computer's USB port
is not stable.

4 [+48V] switch
Turns the phantom power on/off. When you turn this switch
on, phantom power will be supplied to the XLR jack
connected to the [MIC/LINE 1/2] jacks. Turn this switch on
when using a phantom powered condenser microphone.
NOTICE
When using phantom power, observe the following to prevent
noise and possible damage to UR22C or connected
equipment.
• Do not connect or disconnect any devices while the
phantom power switch is turned to ON.
• Set all output level controls to the minimum before turning
the phantom power switch to ON or OFF.
• When connecting devices not requiring phantom power to
the [MIC/LINE 1/2] jack, make sure to turn the phantom
power switch to OFF.
When the phantom power switch is turned on and off, all inputs/
outputs will be muted for a few seconds.
5 [MIDI OUT] jack
For connection to the MIDI IN jack of the MIDI device.
Transmits MIDI signals from the computer.
6 [MIDI IN] jack
For connection to the MIDI OUT jack of the MIDI device.
Receives and inputs MIDI signals to the computer.
• Select [Steinberg UR22C-port1] for the MIDI port when using a
MIDI jack with an iOS app. Please note that [Steinberg UR22C-
port2] is not available.
• Do not activate dspMixFx when using a MIDI device. This may
interfere with stable data transmission/reception.
7 [MAIN OUTPUT L/R] jacks
For connection to monitor speakers. These jacks can be
connected to phone-type (balanced/unbalanced) plugs.
This outputs the MIX 1 signals. To adjust the output signal
level, use the [OUTPUT] knob on the front panel.
