Frequently Asked Questions - GKP-4 ROLAND

How do I power the GKP-4 and GK-2A?
Power is supplied through the GK cable from a GK-compatible device connected to the GK OUT A (POWER SUPPLIER) connector. The power source must be an AC-powered device, not battery-powered.
How many GK devices can I connect?
You can connect up to four GK-compatible devices using the GK OUT A, B, C, and D connectors.
What is the purpose of the GK SW switches?
Each GK SW switch (A-D) controls whether the switch signals (DOWN/S1, UP/S2) from the GK-2A are sent to the corresponding GK device. Set to ON for devices you want to control via the guitar switches.
What do the GK VOL switches do?
Each GK VOL switch enables or disables the GK-2A volume control signals to the connected GK device. When set to OFF, the device's volume is fixed at maximum.
What is the maximum cable length allowed?
The total cable length between the GK-2A, GKP-4, and all connected GK devices must not exceed 10 meters. Using longer cables may cause malfunction.
Can I use this with a battery-powered GK device?
No, the GK device supplying power to the GKP-4 must be AC-powered. Battery-powered devices cannot supply sufficient current.
What cables are included and what can I use instead?
The GKP-4 comes with two 1.2-meter GK cables (C-13D). You can also use optional GK cables GKC-3 (3 m) or GKC-5 (5 m). Do not use non-GK cables.
How do I clean the GKP-4?
Wipe with a soft, dry cloth. For stubborn dirt, use a cloth slightly dampened with mild detergent. Never use benzine, thinners, or alcohol.
What should I do if a device is connected but not used?
Disconnect any unused GK device from the GKP-4 to prevent malfunction and noise. Also remove any cables connected at only one end.
Where can I get repairs?
Refer to the list of Roland Service Centers and authorized distributors provided in the manual for your country.

IMPORTANT NOTES

In addition to the items listed under “USING THE UNIT SAFELY” on page 2–3, please read and observe the following:

Power Supply

- 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.

Placement

  • 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.
  • This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers.
  • To avoid possible breakdown, do not use the unit in a wet area, such as an area exposed to rain or other moisture.

Maintenance

  • 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.
  • Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.

Additional Precautions

  • 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.
  • 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.
  • 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).
  • 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.

Names of Things and What They Do

graph TD A["1: GK IN"] --> B["2: (POWER SUPPLIER)"] B --> C["3: OFF ON GK SW"] B --> D["4: OFF ON GK VOL"] C --> E["5: OFF ON GK SW"] C --> F["6: OFF ON GK VOL"] D --> G["7: OFF ON GK SW"] D --> H["8: OFF ON GK VOL"] E --> I["9: OFF ON GK SW"] E --> J["10: OFF ON GK VOL"] F --> K["11: Off ON GK SW"]…

1. GK IN Connector

Use a GK cable to connect a GK-2A here.

2. GK OUT Connectors (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 Switches

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 VOL Switches

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.

Connecting Devices

* 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.

  1. Turn on the power to the connected GK devices.

  2. Turn the power on to your mixer, amp, etc. Adjust the volume of the connected 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.

Connection Example

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.

graph TD A["Music Player"] --> B["Set to ON (A only)"] B --> C["Set to OFF"] C --> D["GR-33 WP-20G OC-20GVG-88"] D --> E["Guitar Amp"] D --> F["OUTPUT L (MONO)"] D --> G["MIX OUT R (MONO)"] D --> H["RETURN R (MONO)"] D --> I["OUTPUT OUTPUT"] D --> J["GUITAR RETURN"] D --> K["OUTPUT OUTPUT"] D --> L[…

* Set the VG-88's OUTPUT SELECT to "GUITAR AMP" (in the connection example, COMBO AMP is used).

* Set the GR-33's OUTPUT SELECT to "GUITAR AMP."

To play or not to play the various GK devices, use each unit's pedal switch (WP-20G, OC-20G), or expression pedal (VG-88, GR-33).
