O w n e r’s Ma n u a l
Congratulations on your choice of the Roland GKP-4 GK
Parallel Box.
The GKP-4 Parallel Box allows you to perform with up to
four separate GK-compatible devices using a single guitar.
Before using this unit, carefully read the sections entitled:
“
USING THE UNIT SAFELY” and “IMPORTANT NOTES”
(page 2–3; page 4). These sections provide important
information concerning the proper operation of the unit.
Additionally, in order to feel assured that you have gained a
good grasp of every feature provided by your new unit,
Owner’s Manual should be read in its entirety. The manual
should be saved and kept on hand as a convenient reference.

•
Before connecting this unit to other devices,
turn off the power to all units. This will help
prevent malfunctions and/ or damage to
speakers or other devices.
•
Use a reasonable amount of care when using
the unit’s buttons, sliders, or other controls;
and when using its jacks and connectors.
Rough handling can lead to malfunctions.
556
•
When connecting / disconnecting all cables,
grasp the connector itself—never pull on the
cable. This way you will avoid causing shorts,
or damage to the cable’s internal elements.
Pla ce m e n t

•
Using the unit near power amplifiers (or
other equipment containing large power
transformers) may induce hum. To alleviate
the problem, change the orientation of this
unit; or move it farther away from the source
of interference.
558a
•
To avoid disturbing your neighbors, try to
keep the unit’s volume at reasonable levels.
You may prefer to use headphones, so you do
not need to be concerned about those around
you (especially when it is late at night).

•
•
This device may interfere with radio and
television reception. Do not use this device in
the vicinity of such receivers.
When you need to transport the unit, package
it in the box (including padding) that it came
in, if possible. Otherwise, you will need to use
equivalent packaging materials.
355
•
To avoid possible breakdown, do not use the
unit in a wet area, such as an area exposed to
rain or other moisture.
Ma in te n a n ce
401a
•
For everyday cleaning wipe the unit with a
soft, dry cloth or one that has been slightly
dampened with water. To remove stubborn
dirt, use a cloth impregnated with a mild,
non-abrasive detergent. Afterwards, be sure
to wipe the unit thoroughly with a soft, dry
cloth.
402
•
Never use benzine, thinners, alcohol or
solvents of any kind, to avoid the possibility
of discoloration and/ or deformation.

1 . GK IN Co n n e cto r
Use a GK cable to connect a GK-2A here.
2 . GK O UT Co n n e cto rs (A, B, C, D)
Use GK cables to connect GK-compatible devices (such as the VGA-7, VG-88, GR-33, WP-
20G, and OC-20G) here.
When using only one GK device, connect it to GK OUT A (POWER SUPPLIER).
3 . GK SW Sw itch e s
These switches determine whether or not control signals from a GK-2A’s switches (DOWN/
S1, UP/ S2) will be transmitted to the corresponding GK device (ON), or not (OFF).
Switch the GK SW to ON only for GK devices that you want to be affected by switch
movements on a GK-2A.
4 . GK VO L Sw itch e s
These switches determine whether GK-2A volume (SYNTH VOL) control signals are
transmitted to the corresponding GK device (ON), or not (OFF).
Switch the GK VOL to ON only on the GK devices that you want to be affected by
adjustments made using the GK-2A's volume control.
When the signals are not sent to a GK device, the device's volume level is set to maximum.

Co n n e ctin g De vice s
* To prevent malfunction and/or damage to speakers or other devices, always turn down the volume,
and turn off the power on all devices before making any connections.
After first making sure that the power to all devices is off, and that the volume controls are
turned down completely, use the following procedure to connect the devices.
1 . Connect the GK-2A and the GKP-4 with a GK cable. Insert the connector firmly until it locks
in place.
2 . Use GK cables to connect any GK devices to the GKP-4.
* Once the connections have been completed, turn on power to your various devices in the order
specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to
speakers and other devices.
3 . Turn on the power to the connected GK devices.
4 . Turn the power on to your mixer, amp, etc.
Adjust the volume of the connected devices.

Connecting Devices
* Connect only with the GK cable included with this product, or using other GK cables (GKC-3, GKC-5).
Use of other cables can cause malfunction.
* Do not allow the total length of cable used to connect together the GK-2A, the GKP-4, and connected
GK-compatible devices to exceed ten meters.
Connecting with the GKC-10 (ten meters) or C-13B (ten meters), or using all the GKC-5 (five meters)
to connect all the GK devices results in excessive cable length, which may hinder normal operation.
* Allowing a GK device to remain connected to the GKP-4 even though it is not being used can cause
your GK devices to malfunction, and can also be a source of noise. Disconnect any GK device that is
not being used.
* Whether it’s because you' ve used unnecessarily long cables, or because you have only one end of a
cable connected while the other end remains free—improper connections can cause your GK devices to
malfunction, and can also be a source of noise. Use the shortest cable length possible, and pull out any
cables that you don' t need, since they' re only connected at one end anyway.
* Power for the GKP-4 and GK-2A is supplied through the GK cable from the GK device connected to
the GK OUT A connector. Thus, the GKP-4 and GK-2A will not operate with the GK device (or
devices) connected only to the GK OUT B (and/or C and D) connector. When using only one GK
device, connect it to GK OUT A (POWER SUPPLIER).
* Allow the power provided by the GK-compatible device to supply only one other piece of equipment
besides the GK-2A. Connecting more than one GKP-4 or US-20 may cause the maximum current of
the GK-compatible device to be exceeded.
* The GK-compatible device supplying the power should be an AC-powered device, not a battery-
powered one.

Co n n e ctio n Ex a m p le
Here’s how to set up four units, a VG-88, a GR-33, A WP-20G, and an OC-20G, along with a
guitar amp (mono).
* If you wish to play in stereo, use a mixer.
The VG-88 provides the power supply to the GK-2A. The GK SW (DOWN/ S1, UP/ S2) and
GK VOL (SYNTH VOL) are used only for the VG-88.
