- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat
- Do not defeat the safety purpose of the polarized or grounding plug. A polarized plug has two blades with one wider than the other. A grounding plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
- Only use attachments/accessories specified by the manufacturer.
- Protect the power cord from being walked on or pinched particularly at the plugs, convenience receptacles, and at the point where they exit from the apparatus.
- Clean the product only with a soft and dry fabric. Never use liquid cleaning products, as this may damage the products cosmetic surfaces.
- Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/ apparatus combination to avoid injury from tip-over.
- Unplug this apparatus during lightning storms or when unused for long periods of time.
- Avoid placing the product in a location under direct sunlight or near any appliance that generates UV (Ultra Violet) light, as this may change the product surface finishing and cause a change in color.
- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
These apparatus are intended for professional use.
Installation and commissioning may only be carried out by qualified and

- CAUTION: These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.
- WARNING: Only use attachments/accessories specified or provided by the manufacturer (such as the exclusive supply adapter, battery, etc.)
- Before turning the power on or off for all devices, set all volume levels to minimum.
- Use only speaker cables for connecting speakers to the speaker terminals. Be sure to observe the amplifier’s rated load impedance particularly when connecting speakers in parallel. Connecting an impedance load outside the amplifier’s rated range can damage the apparatus.
- KGEAR cannot be held responsible for damage caused by improper use of the loudspeakers.
- KGEAR will not shoulder any responsibilities for products modified without prior authorization.

Assembling instructions
Tightly screw the G-POLE on top of the subwoofer, then set the GH12 12″ array element on top of the G-POLE.Install the GH-JOINT kit on top of the GH12 loudspeaker: insert the four pins on the holes according to the desired tilting angle.Secure the second GH12 on top of the system using the remaining four pins.Set the height of the pole and the tilting angle of the top loudspeaker aiming at the listening area.
GPZA wiring
Once assembled, use the 2 m (6.5 ft) long speaker cable to connect one speakON
connector on the GH12 rear panel to the speakON A connector on the active
subwoofer rear panel.
Use the short joint cable to connect the top GH12 to the bottom GH12
loudspeaker.
By default, the input signal shall be fed with a pair of cables connected to
the XLR Combo balanced input channels 1 and 2 on the GP18A active loudspeaker
rear panel.
If only one cable is used to feed the input channels 1 or 2, the mono
configuration can be set with ArmoníaPlus. GPZ wiring
The GPZ must be bi-amplified feeding the speakON B (on the subwoofer rear
panel) with two signals: one for driving the GH12 array loudspeakers on
terminals 1+ 1–, the other one for driving the GS218 subwoofer on the speakON
B terminals 2+ 2–.
The GP1812A active system implements a 4-channel amp module with DSP: a single
GP1812A can drive a GP1812 passive systems in stereo mode.Once assembled, use
the the 2 m (6.5 ft) long speaker cable to connect one speakON connector on
the GH12 rear panel to the speakON A connector on the active subwoofer rear
panel.
Use the the 15 m (49 ft) long speaker cable to connect one SpeakON B connector
on the subwoofer rear panel to the driving unit (i.e. a GPZA active system).
SpeakON A and speakON B are connected in parallel in order to make the signal
pass through (see next picture).
Cleaning
Use only a soft, dry cloth to clean the housing. Do not use any solvents,
chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives. Do
not use any sprays near the product or allow liquids to spill into any
openings.
