In addition to the items listed under “USING THE UNIT SAFELY” on page 2–3, please read and  
observe the following:  
Po w e r Su p p ly  
Ad d itio n a l Pre ca u tio n s  
553  
307  
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 units 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 itselfnever pull on the  
cable. This way you will avoid causing shorts,  
or damage to the cables internal elements.  
Pla ce m e n t  
351  
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 units 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).  
352  
559a  
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-2As 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  
Heres 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.
