5V DC connector
Connect this to a commercially available USB AC adaptor.
About the USB AC adaptor
Read the section on “Using the Unit Safely” in the manual
included with your USB AC adaptor. Use a USB AC adaptor
that meets the following specications.
5 USB micro-B type
5 Output voltage: 4.8–5.2 V
5 Output current: 500 mA (0.5A) or higher
We have veried that the Rubix operates with typical USB
AC adaptors that meet the above conditions, but cannot
guarantee that it will work with all adaptors that meet these
conditions.
Be aware that even under identical conditions, dierences
in the design specications of a USB AC adaptor and
dierences in the conditions of use might make the Rubix
operate or perform dierently.

[GROUND LIFT] switch
Normally, this switch should
be set to “NOR” (NORMAL).
If ground loop noise occurs,
switching this to “LIFT”
might eliminate the noise.
MEMO
5 The GND (SLEEVE) of the OUTPUT (1L, 2R) jacks (TRS
balanced type) is disconnected from ground.
5 In some cases, there might be no sound if you connect a
balanced cable to an unbalanced device and set this switch
to the “LIFT” position. If so, set the switch to “NOR.”

Ground terminal
Depending on the circumstances of a particular setup, you may
experience a discomforting sensation, or perceive that the surface
feels gritty to the touch when you touch this device, microphones
connected to it, or the metal portions of other objects, such as
guitars. This is due to an innitesimal electrical charge, which is
absolutely harmless. However, if you are concerned about this,
connect the ground terminal with an external ground. When
the unit is grounded, a slight hum may occur, depending on the
particulars of your installation. If you are unsure of the connection
method, contact the nearest Roland Service Center, or an
authorized Roland distributor, as listed on the “Information” page.
