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.

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.

Setting the Size of the Audio Buer
(Windows Only)
Use the control panel to set the size of the audio buer.
1. Access the control panel as follows.
How audio buer size is related to latency
When audio data is transferred between the computer
and the Rubix, the audio data is temporarily accumulated
in the audio buer (a type of memory). This allows audio
data to be transferred smoothly without dropouts.
You can use the “USB buer” setting to change the
size of the audio buer. Increasing the size makes
data transfer more stable, but has the disadvantage of
delaying the sound (“latency”).
The ideal setting is the setting with the minimum delay
that allows stable transfer of audio data.

adjust the input level so that the level indicator does
not light red.

Rubix24
Using the Compressor/Limiter
The Rubix24 and Rubix44 let you use a compressor or limiter.
Compressor/Limiter Settings
Using a compressor makes the volume more consistent. Turning the [THRS] knob toward the right
applies the compressor more strongly, and simultaneously raises the makeup gain (boosts the output
level).
Using a limiter suppresses excessive volume.
Use the Rubix24 or Rubix44’s [COMP/LIMIT TYPE] switch (rear panel) to change this setting.
[COMP/LIMIT TYPE] switch Explanation Response
When the input signal exceeds the level
specied by the [THRS] knob, the level is
COMP1
COMP2
restrained at a xed proportion.
This setting is suitable for instruments, such as
percussion or guitar.
This compressor has a shorter attack time than
COMP1, making it suitable for vocals (the eect
applies more rapidly than COMP1).

LIMIT
This is a limiter. It prevents clipping (distortion)

Mac OS X MIDI Settings
Here’s how to congure the MIDI settings for Mac OS X.
1. In the Mac OS X Finder, open the [Applications]
folder and then the [Utilities] folder, and then
double-click [Audio MIDI Setup].
2. Click [Show MIDI Window] in the [Window] menu.
3. Conrm that [Rubix22] (or Rubix24, Rubix44)
appears in the “MIDI Studio” window or the “Audio
MIDI Setup” dialog box.
If [Rubix22] (or Rubix24, Rubix44) does not appear or if it is grayed
out, it means that the Rubix is not being detected properly.
In this case, click the [Rescan MIDI] icon. Also, try turning the Rubix
o and then on again.
4. Click the [Add Device] icon once.
One [new external device] icon will appear.
5. Click the added [new external device] icon and then
click the [Show Info] icon.
6. Enter “Rubix” in the [Device Name] eld and then
click the [Apply] button.
7. Using your mouse, drag and connect the [
I
] [H]
buttons (which represent the input/output ports of
each device) of the existing [Rubix22] and the newly
added [Rubix] so that they are connected as shown
in the gure.

RADIO FREQUENCY INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment o and on, the user is encouraged to try to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
This equipment requires shielded interface cables in order to meet FCC class B limit.
Any unauthorized changes or modications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
